This section contains information about troubleshooting. It includes information about the following topics.
"Problems Connecting Multiple I/PM Systems to Single Repository"
"I/PM Session Time Out When Using OSSO Requires Browser Refresh"
"Oracle Content Server 10g Provides Incorrect Dates for BPEL"
"Required Fields Added to Oracle Content Server Must Have Default Value Specified"
Oracle I/PM supports 15 digits of precision centered around the decimal separator. Note the min/max values are not inclusive. Some examples:
Scale of 2:
Value must be less than 10,000,000,000,000.00
Value must be greater than -10,000,000,000,000.00
Scale of 5:
Value must be less than 10,000,000,000.00000
Value must be greater than -10,000,000,000.00000
Oracle I/PM uses OutsideIn Technology which requires certain libraries to be installed that are not part of Oracle I/PM. These libraries must be installed on the Oracle I/PM server, Content Server, and client machines using the advanced viewer mode, regardless of the machine platform. For more information on what libraries are required for each platform and how to obtain, install, and configure them, see the Oracle Fusion Middleware Installation Guide for Oracle Enterprise Content Management Suite.
When a search is executed on an application with a number field that returns hits with documents with nothing entered in a number field, either a 0 or a -1 appears in the field. When an application containing documents is modified to have a number field, the search returns -1 for those documents. When a document is uploaded and the number field is left blank, the search returns 0. If a search is executed with the number field as a condition, they are treated as empty fields and when viewed in Oracle Content Server, the fields are empty.
The null number field issue is a result of Oracle Content Server functionality.
By default, the maximum document size that will be indexed is 10MB. This is changed by setting the MaxIndexableFileSize configuration variable in the Content Server repository. The default is MaxIndexableFileSize=10485760. If larger documents require full-text indexing, the value of MaxIndexableFileSize should be increased.
A Oracle Content Server repository can get full to the point of reducing Oracle I/PM efficiency at which time it will not accept any new applications. However, you may continue to upload documents to existing applications in that repository.
A Oracle Content Server repository is considered full if any of the following are true:
The number of security groups exceeds the value of the environment variable IpmMaxGroupLimit.
The number of roles assigned permission to security groups exceeds the value of the environment variable IpmMaxGroupRoleLimit.
The number of metadata fields exceeds the value of the environment variable IpmMaxMetadataFields.
The Content Server configuration setting IpmRepositoryForceFull=True
Setting IpmRepositoryForceFull equal to True allows you to configure Content Server to identify itself as full to I/PM in order to prevent additional applications from being created. This does not prevent documents from being uploaded.
To get additional space for applications, do one of the following:
Install an additional Oracle Content Server repository and set it as a proxy to the main content server. For information on how to configure a proxy server, see the Oracle Fusion Middleware System Administrator's Guide for Content Server.
Increase the values of the IpmMaxGroupRoleLimit and IpmMaxMetadataFields environment variables by editing the config.cfg file directly or by using the Oracle Content Server administrative server. For more information about changing Oracle Content Server environment variables, see the Oracle Fusion Middleware System Administrator's Guide for Content Server.
You can also change these environment variable values in the config.cfg file for your Content Server Repository. For more information, see the Oracle Fusion Middleware System Administrator's Guide for Content Server.
When two or more I/PM systems are using the same Content Server repository, the AgentUser must be configured with the same user. If AgentUser is configured with different repository users for each I/PM system, each I/PM system competes with what AgentUser should be within the repository.
Documents with text content require the fonts necessary to render the document to be available to the OutsideIn rendering engine, which uses TrueType fonts. Fonts are not provided by Oracle. If the font used in a document is not available to OutsideIn, then a suitable substitute will be used. Font substitutions can cause a document to be unreadable, create incorrect text formatting, or cause shifting of data or repagination on text documents, including potentially exposing redacted content.
To ensure that proper fonts are used when rendering documents, the administrator should install them to the client and server system. The server MBean GdFontPath should be set to the directory where the fonts are installed. When using the advanced viewer mode on Linux systems, the fonts can be installed and the environment variable GDFONTPATH set to that directory. If the environment variable is not found, the user will be prompted for that path the first time the advanced viewer mode is used. In cases where an attempt to download a document as a TIFF before the path is set, and error may occur that prevents downloading the TIFF rendition.
For more information, see "Configuring the AgentUser and GDFontPath MBeans".
The following issues involve input agents or input files.
If the input agent will not pick up input files, try the following steps to determine a solution.
Check the settings of the following Oracle I/PM MBeans:
AgentUser: This must be set to a valid user in the security store for the agents to operate. Content Server and I/PM must be restarted if the AgentUser changes. Note that if multiple I/PM systems connect to one Content Server repository, the same AgentUser should be configured for each I/PM system.
CheckInterval: Make sure this is set to a reasonable amount of time for your environment (for example, maybe 1 minute for test systems or 30 minutes for production systems that do not need to get data right away) and ensure that enough time has expired for at least one polling interval to have occurred.
InputDirectories: Examine the list of directories and ensure that they are the correct directories where the input files are stored.
Ensure that the input file has Read/Write permissions for WebLogic Server.
Check the permissions on the input directory paths and make sure they are accessible to the user that is running the WLS managed server.
Look at the input definition in the user interface and make sure the input that is supposed to be processing is marked online and that the input file mask matches the files that are in the directory.
If the input agent is still not running then examine the log files to see if an error was encountered that is preventing the agent from functioning.
Auto-detect does not work if the provided sample file is not large enough to get an accurate determination of the character set. If the sample file is too small, disable Auto-detect input file character set and manually select the character set.
For the steps below, refer to the following directory structure:
Input - Errors – Failed — YYYY-MM-DD – Processed — YYYY-MM-DD – Samples – Stage
If some or all of the entries in the input file have errors, try the following steps to determine a solution.
Look at the Errors directory in which the input file was placed and see if an error file was created. If an error file exists, then open it and examine the last column of the file to determine the specific error.
Examine the input file and verify that the path to the image file is accessible to the user that is running the Oracle I/PM managed server and that the user has permissions to the path and image files.
Copy one of the failing input files to the samples directory and load it into the input definition editor UI. Verify that the mappings are correct and that one of the columns has not shifted.
Finally, look at the Oracle I/PM log file and examine the errors that are listed for the individual lines to determine the exact cause of the problems.
Once you have determined the cause of the error and are able to correct it, copy the corrected input file back into the input directory. For additional information, see "Checking Results and Error Files".
In cases where the advanced viewer applet experiences transformation errors, the first response is to delete temporary files on the user's workstation. Doing so will remove the distribution of OutsideIn files which will cause a new deployment next time the applet is used.
The Advanced Viewer mode renders Group 6 and Group 7 TIFFs, while the Basic Viewer mode supports Group 7 but not Group 6 TIFFs. Group 7 TIFFs must conform to the TIFF standard for JPEG compression. Color images should use YCbCr for photometric interpretation or the image will be treated as a grayscale image. YCbCr is the standard color for JPEG images.
When using Oracle I/PM in a multi-user Linux environment, ensure that individual temp directories are set up for each user. Using a temp directory shared among several users can cause the Advance Viewer to delete temp files for one user that are necessary for another, causing a problem with documents not displaying. Ensure that each user has a temp directory created and configured as recommended by the operating system documentation.
Annotations are placed based on coordinates, and in some circumstances, content underneath the annotation may shift. This can be a particular problem when a redaction annotation shifts, potential exposing sensitive information. For example, if a document contains text data and the font used in a document is not available to the OutsideIn rendering engine, then a suitable substitute will be used. Font substitutions can cause a document to be unreadable, create incorrect text formatting, or cause shifting of data and repagination on text documents, including potentially exposing redacted content.
If annotations become misaligned and expose text they originally covered, ensure that a consistent set of fonts is being used across the servers and clients. For information on font errors, see "Font Errors".
By default, not all exceptions caught within I/PM are logged. In the event that all exceptions need to be monitored, the following steps will help identify all exceptions thrown.
By default, not all exceptions caught within I/PM are logged. I/PM exception handlers do not inherit a log level from a parent logger (oracle.imaging.service). To get exceptions from the core I/PM services, you must explicitly set the logger named oracle.imaging.service.exceptions.To enable some degree of flexibility, it uses the following log levels:
ERROR 1(SEVERE): Logs SYSTEM and DATABASE ImagingExceptions
NOTIFICATION(INFO): Logs SYSTEM, DATABASE, and SECURITY ImagingExceptions
TRACE(FINE): Logs SYSTEM, DATABASE, SECURITY, and USAGE ImagingExceptions
For example, all ImagingExceptions would be logged at throw time by setting oracle.imaging.service.exceptions to TRACE:32.
If documents are deleted from I/PM, administrators can view the entry for the delete action in the Content Server DocumentHistory table. This is the only place for administrators to view audit entries for deleted documents.
A nested stack error, also called a nested exception, is basically an error that has been wrapped by another error, which is standard with Java and other languages to help provide more context to the issue. You can usually find the nested exception by locating the caused by string in the stack trace as shown in bold in the following example. If there is not enough information provided by the Oracle I/PM error, look deeper into the error message to see if other components are involved. Oracle I/PM uses nested stack errors to display repository related problems, BPEL issues, or problems caused by other components. After you locate the possible initial error, check the diagnostic logs for more troubleshooting information.
In the following example, the TCM-00787 error is occurring because the default provider within the Oracle Content Server repository was corrupted and reset (see boldface text).

When using Oracle Single Sign On, POST requests to WebLogic Server will return an internal server error when the Oracle I/PM session has expired. Refreshing the page returns to the I/PM log in page for reauthentication to start a new session.
When using Content Server 10g, the BPEL payload is populated with the incorrect date when the date is less than 1969 or greater than 2068. As a workaround, it is recommended that if you are using dates that fall outside the range of 1969-2068, use four digit years for the date. You can set this using the Content Server System Properties utility.
Users that are getting a host name or IP address that they don't expect for the document URL probably need to configure the Listener Address in their WLS server. This can be done either by setting listen-address in config.xml for the WLS server, or by using the WLS console. To use the console, expand Environment and click Servers in the Domain Structure window. In the Servers Configuration tab, click on the desired server name. Set Listen Address on this page. Restart WLS. For more information about WLS configuration, see Oracle Fusion Middleware Administrator's Guide.
Adding a metadata field to an Oracle Content Server instance using Configuration Manager can cause problems if the field is set as required but no default value is specified. Any metadata fields set as required in Oracle Content Server that do not have default values specified in Content Server prevents Oracle I/PM from creating documents on the Content Server instance. Administrators can prevent issues within Oracle I/PM by either setting a default value for the metadata field or by using Oracle Content Server profiles to address the field.
To view documents on a UNIX operating system, you must ensure that library path and display environment variables are properly set. For more information, see the secion on setting a library path in an environment variable on a UNIX platform in the Oracle Fusion Middleware Installation Guide for Oracle Enterprise Content Management Suite.
