Information Server installations that run on UNIX with WebSphere Liberty encounter a number of issues after it is upgraded to Information Server 22.214.171.124. They might not be able to log in to Information Server Administration console or WebSphere Liberty. Additionally, installations that use DB2 as the metadata repository might experience database failures in actions like metadata import, or discovery.
Information Server operations (for example, metadata import) encounter database errors with a Db2 metadata repository due to missing configuration information.
1. Information Server is installed on Linux or AIX.
2. The installation uses WebSphere Liberty.
3. Information Server 126.96.36.199 was upgraded to Information Server 188.8.131.52 or Information Server 184.108.40.206
4. Next, the installation was upgraded to Information Server 220.127.116.11.
Diagnosing The Problem
For example, /opt/IBM/InformationServer
If any of the following are applicable, then the problem is present in your installation:
1. Check for the presence of a wlp.backup folder.
If it exists, check whether a wlp folder exists within this folder.
2. On the services tier, in ASBServer/conf/iis-client-truststore.p12 check whether any certificates are missing after the upgrade.
3. If Db2 is used as the metadata repository, in wlp/usr/servers/iis/dataSources.xml check whether strings useJDBC4DataType and useJDBC4ColumnNameAndLabelSemantics are not present.
Resolving The Problem
This approach is less risky and less likely to encounter regression issues.
Restore from backup the Information Server version that was installed before 18.104.22.168 was installed.
Follow the 22.214.171.124 installation instructions and ensure that section 3.3.8 is followed to clean up the WebSphere Liberty folders before the installation is started.
Option 2: Restore the WebSphere Liberty folders, and reapply the Fix pack
1. Stop WebSphere Liberty.
2. Back up your wlp.backup and wlp folders.
cp -r <INSTALL_LOCATION>/wlp.backup /opt/backup/wlp.backup
cp -r <INSTALL_LOCATION>/wlp /opt/backup/wlp
3. Remove <INSTALL_LOCATION>/wlp folder.
rm -rf <INSTALL_LOCATION>/wlp
4. Restore contents of wlp folder from the wlp.backup folder.
cp -r <INSTALL_LOCATION>/wlp.backup/wlp <INSTALL_LOCATION>/wlp
5. Remove wlp.backup folder.
rm -rf <INSTALL_LOCATION>/wlp.backup
6. If the wlp.new folder exists, remove it.
rm -rf <INSTALL_LOCATION>/wlp.new
7. Check that you have only one wlp folder.
ls -ldr <INSTALL_LOCATION>/wlp*
Now, the wlp folder is back into the state it was in before 126.96.36.199 was installed.
8. Reapply 188.8.131.52 with the -force option.
Option 3: Apply Information Server 184.108.40.206 Service Pack 4.
