21 Oracle Technology Adapters

21.1.1.1 ECID Propagation Is Not Supported by Oracle Technology Adapters

ECID (Execution Context Identifier) propagation is not supported by Oracle Technology adapters. The ECID is used to keep track of message flow in Oracle Enterprise Manager, and hence this feature is not available in Oracle Technology adapters.

21.1.1.2 Retry Occurs for the Specified Retry Interval Even on Undeploying the Composite

Adapter references for which retries are specified at the binding level, continues to retry for the cumulative retry interval (retry count * retry interval) even after the composite is undeployed.

If you have configured the retries, as shown in the following example:

<property name="jca.retry.count" type="xs:integer" many="false"                override="may">20</property>
<property name="jca.retry.interval" type="xs:integer" many="false"                override="may">10</property>

Based on this configuration the interval should be 200 seconds, and even if the composite is undeployed after 30 seconds during the retry, the retry continues till the cumulative retry interval (retry count * retry interval) is reached.

21.1.1.3 Outbound Adapter Does Not Perform an Outbound Retry If the Outbound Adapter Throws an Exception with GLOBAL_RETRY

If an outbound adapter throws an exception with GLOBAL_RETRY, then the retry configured at the outbound adapter level will not take effect. The retry falls back to the caller which could be a BPEL process. It is observed that the retry happens from the inbound to the BPEL process (caller of BPEL process) in either of the following transaction semantics in Oracle BPEL process:

Scenario 1:

<property name="bpel.config.transaction">requiresNew</property>
<property name="bpel.config.oneWayDeliveryPolicy">sync</property>

Scenario 2:

<property  name="bpel.config.transaction">required</property>
<property name="bpel.config.oneWayDeliveryPolicy">sync</property>

If the adapter throws a LOCAL_RETRY, then the retry configured at the outbound adapter level will take effect.

Note that for the inbound retry to work, Oracle BPEL process must not have any dehydration points.

21.1.2.1 Files Lost During an SOA Server Failover

The Oracle File Adapter picks up a file from an inbound directory, processes the file, and sends the processed file to an output directory. However, during this process if a failover occurs in an SOA managed server, then the file may be lost because of the nontransactional nature of Oracle File Adapter. As a result, some files read by the inbound adapter may not be sent to the output directory. You must configure the Oracle File Adapter for high availability, to ensure that files are not lost during a failover.

21.1.2.2 DOM Parsing Exception at Run Time

When Oracle File and FTP Adapters read a Unicode XML file with byte order mark (BOM), a DOM parsing exception is thrown at runtime. If the Unicode XML file does not use BOM, then an exception is not thrown.

21.1.2.3 Rejection Handling Not Working Properly for XML-Debatching Scenarios

In case of debatching scenarios with XML payloads that have errors such as extra tags and spurious data, output files are created along with the rejected messages.

21.1.2.4 JCA Property Updates from Enterprise Manager Console Are Not Applied If a Logical Directory Is Used

If Oracle File and FTP Adapters use logical directories for inbound or outbound operations, then JCA property updates from Oracle Enterprise Manager Console are not applied.

21.1.2.5 Prerequisite for Oracle FTP Adapter Debatching Scenarios on FTPS

You must use a synchronous process in case of Oracle FTP Adapter debatching scenarios on FTP over SSL (FTPS) for large payloads. If a synchronous process is not used, then the FTP server throws the error code, 421.

21.1.2.6 Chunked Read Feature Not Supported for Secure FTP

The Chunked Read feature of Oracle FTP Adapter is not supported for SFTP (Secure FTP) using SSH transport.

21.1.2.7 Editable Append Property With Dynamic File Name

When a dynamic file name is specified for an output file, the Append property must not be edited. However, the Oracle Enterprise Manager Fusion Middleware Control Console allows you to edit the Append property even when you specify a dynamic file name for an output file. Ensure that you do not edit the Append property when you specify a dynamic file name for an output file.

When using a dynamic file name the value of the Append property must be false. By default, the value of the Append property is false and this must not be edited while using a dynamic file name.

21.1.3.1 Oracle AQ Adapter Reading Field from Object Type Depends on Server Locale Encoding

In an SOA project that contains outbound AQ adapter, Mediator or BPEL, and an inbound AQ adapter, when you select the business payload option as Field within the Object, the national characters are garbled.This issue depends on server locale encoding and exists only on native locale. However, when the server is running on UTF-8 encoding, this issue does not exist.

21.1.3.2 Oracle AQ Adapter Does Not Dequeue Messages from Queues in Oracle E-Business Suite Applications

It is recommended that you use Oracle Adapter for Oracle Applications to dequeue from queues in E-Business Suite Applications and not Oracle AQ Adapter.

21.1.4.1 Example of Flow Control Settings for Oracle JMS Adapter

Anytime the exception weblogic.messaging.kernel.QuotaException: Quota blocking time exceeded and no quota available is encountered, WLS JMS provider allows flow control settings that you can tweak to control the number of messages that are produced/consumed.

For more information about tweaking the control settings, see

http://e-docs.bea.com/wls/docs90/ConsoleHelp/pagehelp/JMSjmsconnectionjmsconnectionfactoryconfigflowcontroltitle.html

The following is an example of the flow control settings used and the various thresholds for a message carrying a payload size of 5k:

Config JMSServer:
    Message Buffer Size:5000
    
Config JMSConnectionFactory:
    Flow Control:
    Flow Maximum: 30
    Flow Minimum: 1
    Flow Interval: 10
    Flow Step: 10
  
check Flow Control Enabled
    Default Delivery: Send Timeout: 3000000
    
Config JMS Destinations:
       Bytes Threshold High: 50000
       Bytes Threshold Low:  50
       Messages Threshold High: 100
       Messages Threshold Low: 1
       Set Quota

21.1.4.2 Oracle JMS Adapter Re-entrant Wizard Displays a Warning Message When the Destination and JNDI Names Are Invalid

While migrating a project from one environment to another, Oracle JMS Adapter Wizard populates the Destination and JNDI name fields in edit mode in the following pages:

• Consume Operation Parameters page

• Produce Operation Parameters page

• Request Operation Parameters page

• Reply Operation Parameters page

• Request/Reply Operation Parameters page

However, if you click Next, the Adapter Configuration Wizard validates whether this is a valid destination, and accordingly, displays a warning message if found to be invalid. You have the option to proceed or enter a valid destination.

21.1.4.3 Distributed Topic in Clustered Environment Creates Extra Messages

When you use Oracle JMS adapter with a distributed topic deployed in a cluster, the scenario would result in more messages processed than the actual number of messages passed to the topic.

Each subscriber to the topic is handed a copy of the message to be processed by WLS JMS. So, the number of processed messages will be equal to the number of active subscribers on the distributed topic. This is a known behavior of Oracle WebLogic JMS in Oracle WebLogic Application Server 10.3.

21.1.5.1 The Value Of the Active Unit Of Work Property Is Not Saved for Outbound SELECT Operation

While configuring an outbound Oracle Database Adapter to perform a SELECT operation, if you select Get Active Unit of Work in the Adapter Configuration Wizard - Advanced Option page, then the value of the GetActiveUnitofWork property is not saved in the .jca file.

The workaround for this issue is to manually add this property in the .jca file of the Oracle Database Adapter, as shown in the following example:

<property name="GetActiveUnitOfWork" value="true"/>

21.1.5.2 The Binding Fault Retries During Remote Fault Is Not Captured in the Oracle Enterprise Manager Console

Consider a scenario in which the Oracle Database Adapter retries the transaction at remote fault (that is, when the database is down) in a condition where the binding fault retry is specified in the composite.xml file, and there is no fault policy defined. In such a scenario, the binding fault retry performed by the Oracle Database Adapter is not captured in the Audit Trail in the Oracle Enterprise Manager Console.

21.1.6.1 Oracle MQ Series Adapter Does Not Support Asynchronous Request-Response Pattern for Mediator

Oracle MQ Series Adapter does not support asynchronous request-response pattern (where Mediator is the server).

21.1.6.2 Oracle MQ Series Adapter Does Not Perform an Outbound Retry If the Outbound Resource Is XA

If you select the outbound resource as XA, then the Oracle MQ Series Adapter throws an exception and does not retry because it does not support an outbound retry with outbound resource as XA. On the other hand, if the outbound resource is non-XA, then the retry happens correctly.

21.1.6.3 Oracle MQ Series Hangs If the Channel Is Brought Down in a Cluster Environment

When working with more than one managed server, if you try to bring down the channel, then Oracle MQ Series hangs. This occurs in both Windows and UNIX operating systems.

21.1.6.4 Adding Additional Encoding Not Supported

Standard Java encodings and their mappings are provided with the MQ Series Adapter but the Adapter Configuration Wizard does not support addition of additional Java encodings that you may require.

To add support for the standard Java encodings that are not provided in the list, you can perform the following steps:

1. Extract the MQSeriesAdapter.jar file from the MQSeriesAdapter.rar file.

2. Extract the mq.properties file from the MQSeriesAdapter.jar file.

3. Add the entry in the mq.properties file. This file has two entries for a mapping between MQ Series encoding and Java encoding. For each new encoding that you require, you must make two entries to the mq.properties file. Make an entry for the MQ Series encoding to the corresponding Java encoding and the other entry for the Java encoding to the corresponding MQ Series encoding.

21.1.7.1 Oracle Socket Adapter Not Supported On a Cluster-Based Environment

Oracle Socket Adapter is not supported on a cluster-based environment. If you try to deploy an inbound Oracle Socket Adapter in a clustered environment, then one of the managed servers throws an error message that the server's port is already in use.

21.1.8.1 Delimited by White Space Option Not Supported in NXSD

In the Specify Delimiter's page of the Native Format Builder wizard, the White space (any number of tab, space) option in the Delimited by list is not supported.

21.1.9.1 Populating Default Values for Record Types While Using PL/SQL APIs

Certain PL/SQL APIs exposed from Oracle E-Business Suite take record types as input. Such APIs expect default values to be populated for parameters within these record types for successful execution.

The default values are FND_API.G_MISS_CHAR for characters, FND_API.G_MISS_DATE for dates, and FND_API.G_MISS_NUM for numbers. Adapter for Oracle Applications can default these values when the parameters within the record type are passed as nil values, as shown in the following example:

<PRICE_LIST_REC>
<ATTRIBUTE1 xsi:nil="true"/>
<ATTRIBUTE2 xsi:nil="true"/>
<ATTRIBUTE3 xsi:nil="true"/>
...
</PRICE_LIST_REC>

This can be achieved with the help of a function in a Transform activity, or by directly passing the XML input with nil values and then assigning them to the record types within an Assign activity.

21.1.9.2 Re-creating Wrapper Packages While Using Existing PL/SQL SOA Composites Against a Different Release Instance

When a user has a SOA composite of a PL/SQL API created against an Oracle E-Business Suite Release 11i instance and intends to use it against the Release 12 instance or vice versa, for the compatibility in the target instance, the wrapper package of the SOA composite must be recreated. This approach updates the signature in the generated wrapper SQL file for the target instance and avoids the possible confusion whether the signature is the same or has changed in the target instance.

21.1.9.3 Locating SQL Scripts in XSD Folder and Recreating Wrapper Packages for Concurrent Program SOA Composites When Deploying them to Different Instances

When a user creates a Partner Link by selecting a concurrent program through Adapter for Oracle Applications, the SQL script that creates a wrapper package to submit the concurrent request is getting generated under the XSD folder in the composite artifacts and is not directly under the root composite folder. Therefore, if a user creates the composite against one Oracle E-Business Suite instance and deploys it on a different Oracle E-Business Suite instance, the user needs to find the script under the XSD folder and run the same against the target instance.

21.1.9.4 Using Old Retry Property Names for Business Event Inbound Retry to Work Properly

For business event inbound retry to work properly with Adapter for Oracle Applications in this release, users need to use the older retry property names retryMaxCount and retryInterval in place of the new jca retry properties jca.retry.count and jca.retry.interval.

21.1.9.5 Retried Instances of Adapter for Oracle Applications Have Non-unique ECIDs

All retried instances of Adapter for Oracle Applications share the same ECID. The ECID of the original instance also does not match the ECIDs of the corresponding retried instances.

21.1.9.6 Reselecting Applications Database Connection from the Wizard Will Not Work at Design Time

When multiple applications database connections are created in Oracle JDeveloper, if a user selects one database connection in the Adapter Configuration Wizard and clicks the Next button, but then realizes that a different database connection should have been chosen, instead of clicking the Back button to reselect a new database connection, he or she has to cancel the Wizard and restart the process. Clicking the Back button and reselecting a different database connection will not work in this release.

21.1.9.7 Rejection Handling Is Not Working

In case of an occurrence of a fault when a composite fails to process a message, the rejected message will not be handled appropriately by Adapter for Oracle Applications in this release.

21.1.9.8 Manually Adding Rule Function and Out Agent Values in the Event Subscription While Connecting to an 11.5.9 Instance

When trying to create a new business event Partner Link with Oracle E-Business Suite Release 11.5.9, the associated event subscription is also created with the values for Rule Function and Out Agent as blank. As a result, the subscription will not be executed when the business event is raised.

The workaround is to manually edit the subscription by adding the value WF_RULE.DEFAULT_RULE as the Rule Function and WF_BPEL_QAGENT<system_name> as the Out Agent.
