This section lists the known issues and limitations for 11g Release 2 (11.2) release. They are grouped into the following categories:
9777682: CONTROL CENTER SERVICE MAY FAIL TO START WITH ORA-29532 ERROR ON AIX ON POWER (64-BIT)
On IBM AIX on POWER Systems (64-bit), the Warehouse Builder Control Center Service may fail to start with the error ORA-29532 when started from within the Oracle Database (for example, using start_service.sql or the automatic startup from check_service job).
Workaround: You can use any of the following workarounds:
Start the Control Center Service from the command line. For example, use the following command:
echo owbsys_pwd | ;/run_servcie.sh -manual $ORACLE_HOME OWBSYS HOST:PORT:SID
Implement MPROTECT_TXT=OFF at the Oracle Listener used by MGW, as described in Note 1135185.1.
8596439: WAREHOUSE BUILDER ONLINE HELP LINKS FROM DESIGN CENTER START PAGE NOT WORKING
In the Oracle Warehouse Builder integrated installation that is included with Oracle Database 11.2, links from the Start Pages in the Design Center to the Warehouse Builder online help will not function properly. This problem does not affect the Oracle Warehouse Builder standalone installation.
Workaround: To enable invoking online help from the Start Pages, temporarily rename or delete the file ORACLE_HOME/jlib/oracle_ice.jar.
8661211: OWB DESIGN CENTER WARNING: UNKNOWN DIRECTIVE: SETSKIPJ2SDKCHECK
When you start the Oracle Warehouse Builder Design Center on Windows, you may notice the following warning in the command window that is displayed while starting the Design Center:
WARNING: Unknown directive: SetSkipJ2SDKCheck
Workaround: You can ignore this warning and proceed with logging in to the Design Center.
6074518: UI MESSAGES ARE NOT DISPLAYED IN SQL*PLUS WINDOW
In the Design Center, if you attempt to start the SQL*Plus window from the Tools menu, you may encounter errors. For certain languages such as Japanese, Korean, and Chinese, you may not be able to invoke the SQL*Plus window from the Design Center. Or, you may not be able to see user interface messages.
Workaround: Invoke SQL*Plus from a tool other than Warehouse Builder.
5031270: NAMES OF SEEDED OBJECTS IN THE REPOSITORY ARE NOT TRANSLATED
Seeded objects in the repository are not translated. These include, for example, the names of predefined transformations as displayed under the Public Transformations node of the Globals Navigator. This also includes the default project named MY_PROJECT, the default Control Center named DEFAULT_CONTROL_CENTER, the folder called DERIVED_DATA_RULES that contains derived data rules, and the default configuration called DEFAULT_CONFIGURATION.
3066632: WAREHOUSE BUILDER FLAT FILE SAMPLE WIZARD COUNTS A MULTIBYTE CHARACTER LENGTH AS 1
When translated into Japanese, the Warehouse Builder Flat File Sample Wizard does not handle multibyte characters in delimited files correctly. The wizard handles a multibyte character in delimited files as 1 length.
Workaround: Manually edit the length using the Flat File Sample Wizard.
Limitations on Using Database Links Between Oracle Database Versions
When a Warehouse Builder mapping that uses database links for data movement between Oracle databases is executed on a given target database, connectivity between database versions will be limited by compatibility supported for database links between the source and target database. For example, a Warehouse Builder mapping running on Oracle Database 11.2 cannot access data on Oracle Database 10.1 over a database link. See Metalink Note 207303.1 for a compatibility matrix that details support for database links between database versions.
6050580: MAPPINGS WITH TIMESTAMP DATA MAY BEHAVE INCORRECTLY
Under some conditions, you may encounter unexpected behavior when running a mapping that loads and transforms timestamp data. For example, if you deploy and run a mapping that transforms a column from TIMESTAMP type to VARCHAR2, the resulting data in the target column may be incorrect.
Workaround: This behavior does not arise when using the Mapping Debugger. Run the mapping and load the data using the Mapping Debugger.
9882655: DEFAULT EXECUTION UNIT FOR CODE TEMPLATE (CT) MAPPINGS MAY NOT ALWAYS BE VALID
Warehouse Builder assigns default execution units to a Code Template (CT) mapping in the following circumstances:
When the user selects Default Execution Units in the execution view of the Mapping Editor
When validating or generating code for a CT mapping with no assigned execution units
When importing a CT mapping with no assigned execution units from MDL
You should always review automatically generated default execution units for CT mappings, to ensure that processing and data are distributed optimally among locations. Note that for some complex mappings, Warehouse Builder may generate default execution units that fail to validate. In such cases, use the Execution View to assign operators to execution units manually.
9830333: ERROR PLS-00305 WHEN DEPLOYING MAPPINGS WITH A REPOSITORY HOSTED ON ORACLE DATABASE 10.2
When hosting the Warehouse Builder repository in Oracle Database 10.2, and using Table operators with long physical names in a mapping, Warehouse Builder may generate PL/SQL code containing types with non-unique names. In such cases, deployment fails with error PLS-00305.
Workaround: Assign shorter names to the Table operators.
To connect to non-Oracle databases, you need the JDBC driver corresponding to that database. Non-Oracle JDBC drivers are not shipped as part of the Oracle Warehouse Builder software. You can obtain the JDBC drivers from the vendor and copy them to the OWB_HOME/owb/lib/ext folder.
Table 1 lists the drivers that are required to connect to DB2, SQL Server, and Teradata. For other databases, consult your vendor.
7135670: OMBPLUS CANNOT LOAD SCRIPTS CONTAINING NON-ASCII CHARACTERS
If you use OMB*Plus to run a Tcl script containing non-ASCII characters, the characters may be corrupted in OMB*Plus. Scripts with non-ASCII NLS characters may not execute successfully. There is no workaround.
5215322: WAREHOUSE BUILDER CONNECTOR TO SAP R/3 REQUIRES SAP LIBRARY FILE
Workaround: To access SAP R/3 in the Design Center, first obtain the SAP RFC library from SAP and copy it to the OWB_CLIENT_HOME/owb/bin/admin directory.
To access SAP R/3 in the Control Center, first obtain the SAP RFC library from SAP and copy it to the OWB_SERVER_HOME/owb/bin/admin directory. OWB_SERVER_HOME is the directory where the Warehouse Builder Control Center Service is installed.
Using Oracle Warehouse Builder 11g Release 2 in an Exadata environment requires additional setup steps. Please contact Oracle Support for details.
5129228: MULTIPLE REPOSITORY BROWSER SESSIONS FROM A SINGLE CLIENT MACHINE NOT SUPPORTED
If you launch multiple Repository Browser sessions from a single Internet browser on a single client machine, you will encounter unexpected results. This scenario is not supported. As a consequence, you cannot browse multiple repositories with a single Internet browser on a single machine.
Workaround: Each Repository Browser session requires its own Internet cookies storage. If feasible, you can launch multiple, different Internet browsers to maintain separate Repository Browser sessions on the same machine.
9835013: ARRAYINDEXOUTOFBOUNDSEXCEPTION DURING MDL IMPORT
When importing MDL files, you may encounter one of the following errors:
Trying to access invalid Object
MDL1261: Error importing OWBAssoc_CopyOfMDW
Workaround: You can use one of the following workarounds:
Increase the heap size when running the Repository Assistant
For Windows, edit the OWB_HOME\owb\bin\win32\reposinst.bat file. For Linux, edit OWB_HOME/owb/bin/unix/reposinst.sh. Increase the value set for the -Xmx flag.
Increase the heap size when running the Design Center client
Edit the OWB_HOME/bin/owb.conf file and increase the value set for the -Xmx flag in the AddVMOption.
Oracle Warehouse Builder 11.2 Repository Must Contain a Workspace Before Upgrade of Oracle Warehouse Builder 10.2 or 11.1 Repository MDL Export
If you are upgrading a Warehouse Builder 10.2 or 11.1 repository to Warehouse Builder 11.2 by exporting the entire repository to MDL with the Repository Assistant, then importing it into Warehouse Builder 11.2, then your destination Warehouse Builder 11.2 repository must have at least one Warehouse Builder 11.2 workspace in it before you can import the MDL.
If your Warehouse Builder 11.2 repository does not already contain a workspace before import, then you must create a dummy workspace, with a name that does not conflict with the names of any workspaces to be imported.
Follow the instructions in Oracle Warehouse Builder Installation and Administration Guide to create a workspace. At step 6 in the Repository Assistant, assign a workspace name and workspace owner that do not conflict with workspaces and workspace owners you actually plan to use. Note that if importing a Warehouse Builder 10.2 repository, the workspace name will be the name of the source schema in which the repository was stored in Warehouse Builder 10.2
You can then run Repository Assistant again to import your Warehouse Builder 10.2 or 11.1 repository export MDL file to your Warehouse Builder 11.2 repository.
Patch Addressing Multiple Repository Upgrade Issues
Before upgrading or migrating repository contents from a previous release, review Note 1074813.1 on My Oracle Support, as well as the white paper "OWB 11gR2: Upgrade and Migration Paths" for details of migration options and processes, as well as known issues that may affect the migration process.
Customers using Warehouse Builder 11.2.0.1 should consider applying patch 9802120, which resolves all known upgrade and migration-related issues as of the date of its release. See My Oracle Support for more details.
Use the following URL to access My Oracle Support:
9970120: UPGRADE TABLE DEPLOYMENTS MAY FAIL WHEN USING CONTROL CENTER SERVICE ON DOUBLE-BYTE CHARACTER SET PLATFORMS
When running the Control Center Service on a platform with double byte character sets, an Upgrade deployment of a table may fail. In this situation, Warehouse Builder generates an invalid upgrade script.
Workaround: Force the Control Center Service to run in English by adding a JVM option to run_service.sh (on Linux) or run_service.bat (on Windows) and then restarting the Control Center Service.
On Linux, edit the OWB_HOME/owb/bin/unix/run_service.sh file and replace the entry set JVM_OPTIONS=-Xmx768M with the following:
set JVM_OPTIONS="-Xmx768M -Duser.language=en"
On Windows, edit the OWB_HOME\owb\bin\win32\run_service.bat file and replace the entry set JVM_OPTIONS=-Xmx768M with the following:
set JVM_OPTIONS=-Xmx768M -Duser.language=en
Required Client-Side Update to Preference.Properties Before Upgrading Repository to Warehouse Builder 11.2.0.2
Using Warehouse Builder Design Center with a Warehouse Builder repository of a different patch level can cause repository corruption. The Design Center can check for inconsistent repository versions at connect time. To enable this check, edit OWB_CLIENT_HOME/owb/bin/admin/Preference.properties on each client installation, and update the OverrideRuntimeVersionCheck and OverrideRepositoryVersionCheck preferences as follows:
OverrideRuntimeVersionCheck=false
OverrideRepositoryVersionCheck=false
This change must be applied manually to all Warehouse Builder 11.2.0.1 Design Center installations.
Applying the Warehouse Builder 11.2.0.2 patch to the Design Center host also updates these preferences.
Large Warehouse Builder Repository Upgrades May Appear to Hang at 96%
When upgrading or importing a very large older repository into Oracle Warehouse Builder 11.2, the import process may appear to hang around 96% complete. The import process can take several hours or more on large files, and will show a 96% complete status for much of this period before completing successfully. Do not interrupt the import process as long as it appears to still be running.
The following is a limited list of known issues from previous releases. These issues were reported in a previous set of release notes and are now resolved in Oracle Warehouse Builder 11g Release 2 (11.2).
