Hi,
The error:
"unable to extend segment by 8 in undo tablespace 'PSAPUNDO'..." must be solved in your system first -
Please refer to SAP note 3155 – "Termination due to tablespace overflow"
It explains the issue and how to fix it.
In addition due to this problem, it might cause problems during deployment of the applications.
Hence it might be that you will need to redeploy the applications, or check for *.err files in the deployment folder of the portal. If there are any, then you should remove the suffix *.err, and restart the system.
For further details please refer to SAP note 1130469 - Deployment failure of PAR and EPA (EPT) files in the portal.
The problem you are facing was already reported in the SCN, and was solved. See the following thread:
java iview Runtime error after Portal SP Update
It contains detailed explanations about the problem analysis.
I hope it will solve your issue as well,
Thanks & regards,
Michal Zilcha-Lang
