Problem(Abstract)

Unable to login to IBM Information Governance Catalog

Symptom

When attempting to login, receiving error:

"error occurred on todays date at ___ time further details may be found in the server logs... " and "localtrancoor e wltc0017e..." and "agent checker handshake has not been established to the asb agent at (server name), port 35131 for over 300 seconds."

IBM Websphere Application Server (WAS) log SystemOut.log shows:


An unexpected error occurred on the server.
com.ibm.iis.isf.security.SessionLimitExceededException: The maximum number of sessions has been reached.

com.ibm.ws.webcontainer.webapp.WebApp logServletError SRVE0293E: [Servlet Error]-[ServicesFrameworkServlet]: java.lang.NullPointerException


Cause

The issue was due to the maximum sessions being reached.


Diagnosing the problem

On the IBM Infosphere Information Server Services tier, run these commands from the <InformationServer Install Path>/ASBServer/bin:

> ./iisAdmin.sh -key com.ibm.iis.isf.security.TrustedSessionTokenCacheMaxCapacity -d

This command will return the maximum number of trusted sessions. The default is 1000

> ./SessionAdmin.sh -url https://servername:9445 -user <isadmin> -password <password> -lss

If there are 1000 sessions, you are having this problem

Resolving the problem

Confirm that no one is logged on and then follow the steps below.

Shut down your Engine and NodeAgents.

On the Information Server Services tier, run these commands from the <InformationServer Install Path>/ASBServer/bin:
> ./iisAdmin.sh -key com.ibm.iis.isf.security.TrustedSessionTokenCacheMaxCapacity -d

This command will return the maximum number of trusted sessions. The default is 1000

> ./iisAdmin.sh -key com.ibm.iis.isf.security.TrustedSessionTokenCacheMaxCapacity -value 1010 -set
where 1010 is the maximum number of sessions from the above command plus 10

> ./SessionAdmin.sh -url https://servername:9445 -user <isadmin> -password <password> -kss

> ./iisAdmin.sh -key com.ibm.iis.isf.security.TrustedSessionTokenCacheMaxCapacity -value 1000 -set

Shutdown WebSphere.

Restart everything.

Test and verify if users are able to login.

BLAFS is a bloat-aware filesystem for container debloating. The design principles of BLAFS are effective, efficient, and easy to use. It detects the files used by the container, and then debloats the container by removing the unused files. The debloated containers are still functional and can run the same workload as the original containers, but with a much smaller size and faster deployment. https://github.com/negativa-ai/BLAFS?tab=readme-ov-file
