November 2010

This document provides various troubleshooting scenarios that you might encounter while working with Oracle Enterprise Manager System Monitoring Plug-ins.

Troubleshooting Common Issues for All Plug-Ins

The following sections provide common troubleshooting scenarios related to all plug-ins.

Installation and Deployment Issues

This section addresses installation and deployment issues.

Preferred Credentials Not Set

You might encounter the following error if you have not set the preferred credentials when you attempt to undeploy the plug-in:

The preferred credentials are not set for host

Possible Cause— Preferred credentials are not set for the host. It is mandatory to set preferred credentials on all Agents where you want to deploy the plug-in.

Action— Do the following:

From the Enterprise Manager Grid Control, click Preferences.

In the Preferences page, click Preferred Credentials in the left pane.

The Preferred Credentials page appears.

For the Host Target Type, enter the normal user name and password and click Test to ensure that the entered values are valid. If the Test returns successful, then click Apply.

Enter the same user name and password for the Agent Target Type for this host.

In the page that appears, set the credentials.

Preferred Credentials Error

You might encounter this error while deploying the plug-in leading to a deployment failure.

Possible Cause— The Domain User set in the Management Agent service properties to start the service does not have required privileges.

Action— Do the following:

Locally on the Windows node hosting the Management Agent, check that the user starting the Management Agent service belongs to the Local Administrators Group. If not, add it.

Open the Local Security Settings Windows Tool and give the following Advanced Privileges to the user starting the Management Agent service:

Act as part of the operating system

Adjust memory quotas for a process

Logon as batch job

Replace a process level token

Restart the Management Agent service if it is running.

Set the Preferred Credentials for the Management Agent in the Grid Control.

Deploy the plug-in and discover the instances.

To verify the preferred credentials, do the following:

Validate the credentials set in the Host and Cluster Preferred Credentials page.

Log in to Enterprise Manager Grid Control.

Click Preferences from the top-right corner of the page.

From the left menu bar, click Preferred Credentials.

In the Preferred Credentials page, in the table, for the Host target type, from the Set Credentials column, click the icon.

In the Host Preferred Credentials page, in the Target Credentials section, for the host that is running the Management Agent where the plug-in has to be deployed, specify the user name and password, and click Test. If you test runs successfully, your credentials are set correctly.

Run the OS Command job for the Management Agent where the plug-in has to be deployed.

Log in to Enterprise Manager Grid Control.

Click the Jobs tab.

In the Job Activity page, from the Create Job list, select OS Command, and click Go.

Fill up the details required in the following pages, and click Submit to run the job. If the job runs successfully, your credentials are set correctly.

Failure in loading Classpath: Could not create instance : <JDBC DRIVER>

Possible Cause— The JDBC Driver Name in target properties or/and the JDBC Driver in Agent's classpath.lst file is/are incorrect.

Action— Do the following:

Specify the correct JDBC Driver Name in target properties

Specify the correct path of JDBC Driver in Agent's classpath.lst file

This tool is packaged along with Microsoft SQL Server.

For diagnosis using SQL Server Enterprise Manager:

From the Start menu, select All Programs, SQL Server, Enterprise Manager and then SQL Query Analyzer.

Connect to the database instance.

Diagnostic Steps

To monitor a Microsoft SQL Server target, you need to go through 4 phases:

Phase 1— Import the Plug-in on Enterprise Manager Grid Control. See also "Phase 1 Checklist".

Phase 2— Deploy the Plug-in to the Central Agent that will monitor the SQL Server target(s). See also "Phase 2 Checklist".

Phase 3— Discover the SQL Server targets. See also "Phase 3 Checklist".

Phase 4— Ensure that various features for monitoring the discovered SQL Server target are available and display the right behavior. See also "Phase 4 Checklist".

Phase 1 Checklist

Before importing SQL Server Plug-in into Enterprise Manager Grid Control, go to My Oracle Support and review the Certification Note 412431.1 to check which release of the SQL Server Plug-in is certified with which release of:

Grid Control OMS/Agent

Microsoft SQL Server

Phase 2 Checklist

(For Microsoft SQL Server 2000 only)

Before deploying the Plug-in to the Central Agent, ensure that Windows Management Instrumentation (WMI) setup.exe was successfully installed.

Ensure that the namespace root\MicrosoftSQLServer is present and check if

Service WMI is up and running (From Start menu, go to Control Panel, and then Services to verify).

WMI calls (for root/cimv2 and root/MicrosoftSQLServer) work effectively outside the Management Agent. Use any of the Microsoft Diagnostic Tools documented in Diagnostic Tools.

Also, ensure that JDBC calls work effectively outside the Management Agent.

Phase 3 Checklist

Verify the following:

Before discovering SQL Server targets, ensure that you meet all discovery-related pre-requisites. The checklist to follow is:

Preferred Credentials have been set in Grid Control for the Central Agent which monitors the SQL Server instances and for the host on which the Central Agent is running.

(For Release 1 or Release 2 of the Plug-in only) Verify the exact name of the SQL Server Host and the SQL Server instance from the SQL Server Enterprise Manager.

Check that TCP/IP is enabled and verify the TCP/IP port. For details, Enabling TCP/IP Port and Finding TCP/IP Port.

If the target is remote, necessary configuration for remote connection must be done as a pre-requisite.

Phase 4 Checklist

For monitoring of SQL Server targets to occur ensure that you meet the following conditions:

The SQL Server instance has been successfully discovered.

To do this:

In the Enterprise Manager Grid Control, click Targets.

In All Targets page, enter Microsoft SQL Server in Search, and then click Go.

Verify if SQL Server instance you added is listed.

Click the SQL Server name for details

Check if the status of the SQL Server Instance is correct.

To do this:

Go to SQL Server Instance Home page.

Verify the status.

Ensure that the status is not Pending.

In the Alerts page, ensure that SQL Server instance is not listed in the Unknown Availability section.

In the Alerts page, ensure that there are no errors listed in the Errors section for SQL Server instance.

In the SQL Server Instance Home page, ensure that in All Metrics section, date and timestamp is displayed in the column Last Upload.

Note:

Wait for the Schedule Interval (this can be 24 hours) to check that a specific metric is collected.

Some metrics might not be collected (for example, Backups or Jobs if no backup and no job were ever run for that SQL Server instance).

Some metrics might not be collected depending on the release of the Microsoft SQL Server or if some Windows services are not started (for example, the SQL Server Agent)

In the SQL Server instance Home Page, go to Reports section and check if all the reports are available in the List View Reports.

Note:

Some reports might be empty or might display No data found.

In this case, check that the Schedule Interval of the corresponding metric and wait for the Schedule Interval.

Finding TCP/IP Port

After enabling the TCP/IP protocol, restart the SQL Server to apply the changes.

For SQL Server 2000

From the SQL Server Enterprise Manager, right-click the SQL Server instance in the left panel and select Properties. The SQL Server Properties dialog box appears.

In the General tab, click Network Configuration. The SQL Server Network Utility dialog box appears.

Select TCP/IP, click on the Properties dialog box to know the TCP/IP port.

Modifying Access Privileges of SQL Server Services

Note:

Execute the following commands only if the Windows box in which SQL Server resides, is Windows 2003 SP1 or later.

Follow these steps to modify access privileges of SLQL Server services:

Grant authenticated users the right to remotely access Service Control Manager:

Click Start, click Run, type cmd, and then click OK.

Type the following command at the command prompt, and then press Enter:

sc sdset SCMANAGER D:(A;;CCLCRPRC;;;AU)(A;;CCLCRPWPRC;;;SY)(A;;KA;;;BA)S:(AU;FA;KA;;;WD)(AU;OIIOFA;GA;;;WD)

For more information, see http://support.microsoft.com/kb/907460/.

Assign Access right to SQL Server Services:

Click Start, click Run, type cmd, and then click OK.

Type the following command at the command prompt, and then press Enter:

Check the AU (Authenticated Users) access privileges in the output. For example, the default value is:

D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;IU)(A;;CCLCSWLOCRRC;;;SU)(A;;CR;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)

The above output lists CR (Control Access) privilege for Authenticated Users (A;;CR;;;AU).

If the privileges for AU (Authenticated Users) are not same as (A;;CCLCSWRPWPDTLOCRRC;;;AU), set it using the following command by replacing (A;;CR;;;AU) with (A;;CCLCSWRPWPDTLOCRRC;;;AU):

sc sdset SQLServer_service_name D:(A;;CCLCSWRPWPDTLOCRRC;;;SY)(A;;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;BA)(A;;CCLCSWLOCRRC;;;IU)(A;;CCLCSWLOCRRC;;;SU)(A;;CCLCSWRPWPDTLOCRRC;;;AU)(A;;CCLCSWRPWPDTLOCRRC;;;PU)S:(AU;FA;CCDCLCSWRPWPDTLOCRSDRCWDWO;;;WD)

Repeat steps (a) to (c) for SQLServer Agent service also, by replacing SQLServer_service_name in step (a) with the SQLServer_agent_service_name.

General Issues

The following sections list the general issues and workarounds, if any, that can be used to resolve the issues that you may encounter while working with the Microsoft SQL Server plug-in.

Monitoring Issues

This section addresses monitoring issues.

DLL file $AgentHome\sysman\jdbcdriver\ sqljdbc_auth.dll is found missing or was never copied manually. Please copy AMD64 version of sqljdbc_auth.dll at the above location and re-try.

Possible Cause — 64-bit version of sqljdbc_auth.dll is either missing or not copied manually in the specified directory

Action— Download Type 4 Microsoft SQL Server 2005 JDBC Driver version 1.2 and copy the X64 version of sqljdbc_auth.dll to $Agent_home\sysman\jdbcdriver directory. The file sqljdbc_auth.dll is available as part of Type 4 Microsoft SQL Server 2005 JDBC Driver version 1.2 (after unzipping, you will find three files with same name, that is, auth\x86\sqljdbc_auth.dll, auth\x64\sqljdbc_auth.dll, and auth\ia64\sqljdbc_auth.dll)

DLL file $AgentHome\sysman\jdbcdriver\ sqljdbc_auth.dll is found missing or was never copied manually. Please copy IA64 version of sqljdbc_auth.dll at the above location and re-try.

Possible Cause — 64-bit version of sqljdbc_auth.dll is either missing or not copied manually in the specified directory

Action— Download Type 4 Microsoft SQL Server 2005 JDBC Driver version 1.2 and copy the IA64 version of sqljdbc_auth.dll to $Agent_home\sysman\jdbcdriver directory. The file sqljdbc_auth.dll is available as part of Type 4 Microsoft SQL Server 2005 JDBC Driver version 1.2 (after unzipping, you will find three files with same name, that is, auth\x86\sqljdbc_auth.dll, auth\x64\sqljdbc_auth.dll, and auth\ia64\sqljdbc_auth.dll)

Error: Bad arg length for Socket::inet_ntoa, length is 0, should be 4

Possible Cause — DNS resolution has failed. This may be due to incorrect host name specified in the JDBC URL field, failed attempts to contact DNS server, or "down" status of the DNS server.

Action— Check ping and nslookup for the host name specified in the JDBC URL field. If these commands fail, then include the IP address in the JDBC URL field, instead of host name, and check the behavior.

Error: Error in adding target - _Wbem_Remote_Determination_DynamicProperty - Couldn't determine the IP address of the SQL Server Host. Possible reasons are - Host Name or IP address provided in the JDBC URL is not correct - Domain Name Server (DNS) is down or Domain Name resolution failed. Please contact your system/network administrator to resolve the DNS configuration.

Possible Cause — DNS resolution has failed. This may be due to incorrect host name specified in the JDBC URL field, failed attempts to contact DNS server, or "down" status of the DNS server.

Action— Check ping and nslookup of the SQL Server target host machine (provided in the JDBC URL) field from the Enterprise Manager Agent system.

Error: 0x80041010

Possible Cause — WMI repository is not up-to-date. As the class is part of root\cimv2 namespace, it should be available as part of default WMI installation.

Action— Do the following:

At command prompt, repeat running the following command twice or thrice in sequence:

wmiadap /f

wmiadap /resyncperf

Restart Windows Management Instrumentation service.

Note:

This applies only if you use SQL Server plug-in version 3.0.2.0.0 or higher.

Note:

When this error is found for a 32-bit version of SQL Server installed on 64-bit system, instead of using the default wmiadap executable, look for the wmiadap executable under <WINDOWS_ROOT>\SysWOW64, for example, C:\WINDOWS\SysWOW64. Run this copy of wmiadap.exe with the options mentioned above.

Target is In Broken State: Metric Collection Errors Encountered

Note:

This bug has been fixed for Oracle Enterprise Manager Agent version 10.2.0.3 and higher. You might encounter this issue only for Agent versions lower than 10.2.0.3.

Cause — This behavior occurs when target, agent, or both and/or target system become slow or heavily loaded and computation of dynamic properties take longer than the default timeout value.

Workaround — Execute the following command:

emctl reload agent dynamicproperties <target name>:<target type>

OR

You can alternatively resubmit the target instance properties:

Click on the Monitoring Configuration link (under the Related Links section on the plug-in target home page).

Re-enter the encrypted properties.

Click OK.

Test Connection

This section addresses the test connection issues.

General Test Connection Issues

This section addresses general test connection issues.

Error: Missing Properties or WMI Error (with error code)

This may be any of the following:

Missing Properties : [STDINWBEM_HOST]

Missing Properties Error [servername_from_jdbc]

Missing Properties : [version]

Error 0x80007005

Error 0x80041003

Possible Cause — This may be seen when the Management Agent encounters an error while computing any of the Dynamic Properties. To verify the behavior of the computation of Dynamic Properties, try Test Connection. You can try the connection from either the Add Target page (if the target is not already added) or the Target Home page (from the Related Links section, click Monitoring Configuration).

The reason for the failure in Dynamic Property computation may be because the Management Agent process owner and/or the provided System User Name (if the target is on a remote location that is different from the host where the Management Agent is running) do not have adequate privileges and permissions to monitor these targets.

Action — The Dynamic Property computation error needs to be resolved. Details on how to resolve the issue are mentioned below:

If you tested the connection, then after successful testing of the connection, re-enter the password details. On the refreshed page, the password fields may show some encrypted values but those are incorrect values, as the credentials are not cached. So re-enter the passwords and then click OK.

To check whether the user has adequate privileges, try out a test connection using WBEMTEST or CIM Studio. Test the connection by executing queries using these tools from the agent machine to the local or remote target machine.

A failure or error message while connecting to the namespaces root\default, root\cimv2

and/or

root\MicrosoftSQLServer (in the case of SQL Server 2000) helps to find the exact problem.

After confirming this, modify the permissions so that you can add targets. For instructions to modify permissions, refer to Modifying Permissions.

However, if you do not see any error in the connection (or while running the query) through WBEMTEST for root\cimv2 or root\MicrosoftSQLServer (only in the case of SQL Server 2000) namespaces, then check the owner of the Management Agent process and the user that you logged in as and ran the WBEMTEST query. If the above two are not the same, then change the owner of the Management Agent process to the same user that ran the query through WBEMTEST (preferably, this should be a domain account) and check the behavior of the plug-in target or Test Connection.

Check the server name retrieved with JDBC is null. A null value makes the discovery fail.

Action— Refer to the related article on Microsoft Website:

http://support.microsoft.com/kb/303774/

The article 303774 documents the Microsoft bug 354825 and states how the servername can be NULL and how to fix the issue.

Important:

Contact Microsoft Support before applying the steps provided at the above URL.

Error: The host name/ IP address specified in JDBC URL is of Oracle Enterprise Manager Agent system. However, System Username is specified. For a SQL Server target on the same box as OEM Agent, System Username should not be specified.

Possible Cause — In case of Local Monitoring scenario, System User is specified in the System User Name field while adding target.

Action — Remove the System User Name from the System User Name field and re-try.

Error: Failed to connect, Network Error. Possible reasons are: Either JDBC URL is wrongly formed or one of its parameters are wrong

Possible Cause — Incorrect host name in the JDBC URL

Action — Provide the correct SQL Server hostname in the JDBC URL and re-try.

SQL Server is not running

Action — Check the correct port number for the target. For information about checking the port number, see Enabling TCP/IP Port.

Error: Cannot find the key : SOFTWARE\Microsoft\Microsoft SQL Server\SQLSRVR_2000\MSSQLServer\CurrentVersion\\CurrentVersion. Could not connect. Error code = 0x80041003 em_error=Failed while connecting to WMI.

Possible Cause — Following could be the causes of this error:

System user does not have the privilege to access the particular registry key

The registry key does not exist.

Action — Assign Read permission to the registry key(s) as documented. Replace permission entries on all child objects in the Advanced mode.

Error: MSSQL_NumClusterNodes - Error Querying: The user does not have permission to perform this action.

Possible Cause — Database User specified does not have privilege/role to the SQL Server instance.

Action — Assign sysadmin server role to the Database User as mentioned in the above article.

JDBC Test Connection Issues

This section addresses JDBC-related test connection issues.

No Owner for One or More Databases

When you do a test connection, you might encounter this error while adding the target.

Possible Cause: There is no owner for one or more databases in the SQL Server instance.

Action: Do the following:

Ensure that the output of the following are same:

Output of the query select @@servername when ran from Microsoft Query Analyzer tool (after connecting to the database)

The following registry key from the SQL Server target system

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server

Note:

If 32-bit version of SQL Server is installed on 64-bit system, the registry key to be checked on the SQL Server target system is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Microsoft SQL Server.

Using Microsoft SQL Query Analyzer:

Check if exec master.dbo.sysdatabases gives the same error.

See if you find NULL value for the second column for query select name, suser_sname(sid) from master.dbo.sysdatabases.

Run the following command for all the database for which the second column is found NULL:

* *Use <database_name>

* *exec sp_changedbowner username

The username can be the name of any database owner.

Rerun the following query:

select name, suser_sname(sid) from master.dbo.sysdatabases

Now, you should not find the value in the second column NULL.

Run the following query and ensure that the error is rectified:

exec master.dbo.sysdatabases

Error While Obtaining Connection

Possible Cause — The port number provided is wrong.

Action — Provide the correct port number for the target. See Finding TCP/IP Port for details.

JDBC Connection Fails

If the JDBC connection fails, ensure the following:

The specified user exists in the Manage Logins dialog box for the SQL Server instance.

The user has the sysadmin fixed server role.

The SQL Server Authentication method is enabled for the particular instance.

The query select @@servername,@@servicename is not returning a NULL value for the SQL Server instance.

Error : Metric collection error :" The server principal "<username>" is not able to access the database "<dbname>" under the current security context......"

Action — Provide access to that database for the login user.

Error while obtaining connection.[Microsoft][SQLServer 2000 Driver for JDBC]Error Establishing Socket or Failed to Connect.

Possible Cause — The reason can be one of these:

Incorrect port with correct host name

Incorrect host name with correct port

Incorrect port and host name

SQL Server is not running

TCP/IP port is not enabled on SQL Server instance

Action — Provide the correct port and host name. If the SQL Server is not running, then start it. Ensure that the TCP/IP port is enabled on the SQL Server instance.

The following error is encountered:

Action — Execute the following command from sysadmin user:

GRANT VIEW SERVER STATE TO "login name"

WMI Test Connection Issues

This section addresses WMI-related test connection issues.

Metric Collection Error

While doing a test connection, you might encounter the following error:

Can't get query descriptor or execution descriptor

Possible Cause— (Failed to compute wbemremote) - is cluster missing due to wrong URL, wrong credential or wrong sqljdbc.dll file location.

Action— Check the sqljdbc.dll file location, SQL Server status (if status is not Up, start Microsoft SQL Server), URL, and credentials.

WMI Error 0x8004100E

Possible Cause— The 0x8004100E error indicates the Namespace specified could not be found error string.

Action— In this case, ensure the root\MicrosoftSQLServer namespace is enabled. Otherwise the test connection will fail.

Note:

This applies only to SQL server 2000.

Could Not Connect. Error:0x80041064

You might encounter this error leading to a connection failure with a message explaining the failure to connect to WMI.

Troubleshooting IBM DB2 Plug-In

The following sections provide troubleshooting scenarios related to IBM DB2 plug-in.

How To Diagnose

The following sections help you diagnose issues that you may encounter while working with the IBM DB2 plug-in.

Finding TCP/IP Port

The communication port to access the remote IBM DB2 instance can be configured. The default value is 50000.

To find the port for a particular IBM DB2 instance, do the following:

For UNIX Platforms

Open a command prompt.

Enter cd /usr/etc.

Enter cat services.

Start of changeScroll through the list of services until you find the connection port number for the database instance of the remote database.

The instance name is usually listed as a comment. If it is not listed, then complete the following steps to find the port:

Open a DB2 command prompt.

At the DB2 command prompt, run the following command to verify that you are on the correct instance. IBM DB2 will report the current instance.

get instance

Run the following command to find the service name for your instance:

get dbm cfg | grep SVCE

IBM DB2 will report the service name.

For example:

TCP/IP Service name SVCENAME) = db2cdb2inst24

Use the service name to find the port number in the services file.

For example, enter the following command:

grep service_name /etc/services

IBM DB2 will return the information.

For example:

service_name   50012/tcp   # Connection port for DB2 instance instance

For Microsoft Windows Platforms

Open the DB2 Control Center on the remote Windows server.

Right-click one of the available instances for the local machine.

Click Setup Communications.

Click Properties.

The port number is listed in the Properties window.

For z/OS Platforms

Connect to the z/OS system.

Run the following command:

-DISPLAY DDF

The TCPPORT value in the results is the port number.

How To Fix

The following sections help you fix issues that you may encounter while working with the IBM DB2 plug-in.

Using a Suitable Operating System User and Assigning Authorities and Privileges

You might see the following error on the Monitoring Configuration page of the Enterprise Manager Grid Control console:

Figure 1 Error Message When Incorrect Privileges Are Used and When OK is Clicked

Figure 2 Error Message When Incorrect Privileges Are Used and When Test Connection is Clicked

Possible Cause -- You are not using a user or the user you are using does not have the correct privileges.

Action -- Use a user that has at least the minimum privileges. For information about creating a suitable operating system user and assigning authorities and privileges to that user, see Enterprise Manager System Monitoring Plug-in Installation Guide for IBM DB2 Database available at:

http://www.oracle.com/technology/documentation/oem.html

Incorrect Credentials Used

You might see the following error:

Failed to contact the target to be added. Following errors were received while testing the connection to the target. Update the properties accordingly, try Test Connection for testing the properties before saving.

Response - oracle.sysman.emSDK.emd.fetchlet.FetchletException: Error while obtaining connection.Connection authorization failure occurred. Reason: password invalid.

Possible Cause -- You are using incorrect credentials.

Action -- Use correct credentials.

No Data for Health Indicator Metrics

You may not see any data for Health Indicator metrics.

Possible Cause -- You have not enabled the HEALTH_MON database manager configuration parameter.

Action -- For data to be collected for the Health Indicators metric, you have to enable the HEALTH_MON database manager configuration parameter. Only then the table functions -- HEALTH_TBS_HI, HEALTH_DB_HI, and HEALTH_DBM_HI get populated.

Note:

Enabling these settings may result in some overheads, such as CPU and memory. Therefore, follow these troubleshooting steps only if you want to view the Health Indicator metrics.

To enable or disable the HEALTH_MON by CLP (Command Line Processor), run the following command:

db2==> update dbm cfg using HEALTH_MON [on;off]

To check if your changes are effective, run the following command:

db2==> get dbm cfg

The following is the output:

.....
.....
.....
Monitor health of instance and databases (HEALTH_MON) = ON
.....
..........

For more information, access the IBM Web site.

Metric Collection Error for Database Monitoring Metrics

You may see the following error:

Error: oracle.sysman.emSDK.emd.fetchlet.FetchletException: Error while executing query. DB2 SQL error: SQLCODE: -204, SQLSTATE: 42704, SQLERRMC: SYSTOOLS.STMG_DBSIZE_INFO

Possible Cause -- The table STMG_DBSIZE_INFO is not created.

Action -- For data to be collected for the Database Monitoring metric, make a call to the GET_DBSIZE_INFO package so that the STMG_DBSIZE_INFO table gets created and populated with the required data.

The GET_DBSIZE_INFO procedure calculates the database size and maximum capacity. The calculated values are returned as procedure output parameters and cached in the SYSTOOLS.STMG_DBSIZE_INFO table. The procedure caches these values because the calculations are costly.

The SYSTOOLS.STMG_DBSIZE_INFO table is created automatically the first time the procedure runs. If there are values cached in the SYSTOOLS.STMG_DBSIZE_INFO table and they are current enough, as determined by the snapshot-timestamp and refresh-window values, then these cached values are returned.

If the cached values are not current enough, new cached values are calculated, inserted into the SYSTOOLS.STMG_DBSIZE_INFO table and returned, and the snapshot-timestamp value is updated. The last parameter in the GET_DBSIZE_INFO call is refresh window.

Default value refresh window (time difference between successive calls) is 30 minutes. If your database is growing at a faster rate, then you can set a lower value.

To make a call to GET_DBSIZE_INFO by CLP (Command Line Processor), run the following command:

db2==>CALL GET_DBSIZE_INFO(?, ?, ?, -1)

In this case, the refresh window is 30 minutes.

For more information, access the IBM Web site.

Possible Cause— Following could be the causes of the error:

DIAGPATH is not set

Database is down

Action— If DIAGPATH is not set, set the DIAGPATH run from the command line as follows:

db2 update dbm cfg using  diagpath <path>

On Windows systems, the path is <db2 installation directory>\<instance name>

On Linux or AIX systems, the path is <instancehome>/sqllib/db2dump

If the DIAGPATH is already set, metric collection errors will occur if the database is down.

Troubleshooting Sybase Adaptive Server Enterprise Plug-In

The following sections provide troubleshooting scenarios related to Sybase Adaptive Server Enterprise plug-in.

How To Fix

The following sections help you fix issues that you may encounter while working with the Sybase Adaptive Server Enterprise plug-in.

Failed to connect, JZ006: Caught IOException: java.net.ConnectException: Connection refused

Possible Cause— Port number is incorrect.

Action— Specify the correct port number in the JDBC URL.

Failed to connect, JZ00L: Login failed. Examine the SQLWarnings chained to this exception for the reason(s)

Possible Cause— The DB user name and password are incorrect.

Action— Specify the correct DB user name and password.

JZ006: Caught IOException: java.io.IOException OR JZ0I6: An error occurred converting UNICODE to the charset used by the server OR Error message: java.io.CharConversionException:java.io.UnsupportedEncodingException: hp-roman8

Possible Cause— ?charset=iso_1 last is not set in the JDBC URL.

Action— Add ?charset=iso_1 last in the JDBC URL as shown below:

jdbc:sybase:Tds:<HOST>:<PORT>/?charset=iso_1

SELECT permission denied on object <Object Name>, database master, owner dbo

Possible Cause— The user who is currently monitoring the target does not have the required role and permissions.

Action— Check whether the user has all the required roles and permissions as described in the Configuring Sybase Adaptive Server for Monitoring section of the installation guide. If not, grant the required permissions.

<TABLE NAME> not found. Specify owner.objectname or use sp_help to check whether the object exists (sp_help may produce lots of output).

Possible Cause— The <TABLENAME> is not available on the target side. If <TABLENAME> is either master..mon<*> or mon<*>, then the required MDA table is not available.

Action— Check whether the MDA tables are installed. If they are not, install them.

Error Querying: Collection of monitoring data for table '<TABLE NAME>' requires that the '<PARAMETER(S)>' configuration option(s) be enabled. To set the necessary configuration, contact a user who has the System Administrator (SA) role

Possible Cause— The <PARAMETER> shown in the error message has not been enabled.

Action— Enable the <PARAMETER> that is shown in the error message. To understand how configuration parameters can be enabled, refer to the Prerequisites section of the installation guide.

The following shows the configuration parameters to be enabled for each metric.

Report Element Showing "No Data Found" or "No Rows Returned"

Possible Cause— The underlying metric data has not been collected or the data has not been rolled up into hourly views.

Action— For the report element (chart or table) that shows this message, first identify the dependent metric and then check whether metric data has been collected for it.

The following shows the report elements and their dependent metrics. Using this table, identify the dependent metric. Once that is done, go to the All Metrics page of the target in Enterprise Manager Grid Control, and check whether metric data has been collected for that dependent metric. If data has not been collected yet, then check the collection frequency and wait until the collection happens.

Troubleshooting VMware ESX Server Plug-In

The following sections provide troubleshooting scenarios related to VMware ESX Server plug-in.

How To Fix

The following sections help you fix issues that you may encounter while working with the VMware ESX Server plug-in.

Calculation of Dynamic Properties Time Out

The VMware ESX Server target instance has a number of dynamic instance properties that are calculated by the Management Agent when a new target instance is added. This calculation also occurs for an existing target instance as a result of one of the following:

Emctl reload agent dynamicproperties <target_name>:vmware_esx_server

Emctl reload agent (and the target type definition has changed, that is, metadata has been updated)

The plug-in is upgraded (and the target type definition has changed)

The Management Agent has a default timeout of 30 seconds as to how long it will try to recalculate the dynamic properties. It is possible for the calculation of the dynamic properties to time out.

Possible Cause -- The calculation of the dynamic properties can time out when the Management Agent is under heavy load.

The ESX Server target type has a dynamic property named version that is used to provide different versions of metric definitions for different versions of ESX Server. If version does not get computed within the timeout period, then metric collection errors will occur with a message similar to the following one:

Error encountered while retrieving metric VMConfigSumm.  Exception in thread "main" java.lang.NumberFormatException: For input string: "%version%"
at java.lang.NumberFormatException.forInputString(NumberFormatException.java:48)
at java.lang.Integer.parseInt(Integer.java:489)
at java.lang.Integer.valueOf(Integer.java:595)
at oracle.sysman.mpi.vmware.esx_server.MetricCollector.main(MetricCollector.java:269)

Action --You can resolve this issue in one of the following ways:

The emctl reload agent dynamicproperties command can be rerun while the Management Agent is under lighter load.

It is possible to increase the default value of 30 seconds for the timeout period.

In $AGENT_HOME/sysman/config/emd.properties, there is a Management Agent property named dynamicPropsComputeTimeout. You can uncomment that definition and increase the value of the timeout period, for example, to 120 seconds. This will then apply to all target types.

It is also possible to increase the timeout period for a particular target type by adding the following declaration where nn is the number of seconds for the timeout:

dynamicProspComputeTimeout_vmware_esx_server=nn

When either of these values are added or changed, the Management Agent must be refreshed with an emctl reload agent command in order to recognize the new value.

Documentation Accessibility

Our goal is to make Oracle products, services, and supporting documentation accessible to all users, including users that are disabled. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.
