JSPM - Restore

Hello All,

We are using EP 7.0 with BI 7.0 in two different unix system with SP

level 15 in both the stacks. Our issue is few month before we applied

the sp for abap(BI system) and JAVA(Portal system). No issue we faced

in the BI system.

After applied the SP15 for JAVA stack we faced lot many problem from

user and administration side (eg : customized Theme changed to

original , SSO expire(system received an expired SS0 ticket) ).

Now we are planned to apply the latest SP 17 for both prodcution

system.We need pre and post informations about the java patch(JSPM)

application.Like OS-files directory backup details, portal frontend

side,precautionary steps.

Is there any documents regarding this apart from help.sap.com.

Look forward to move ahead
