After performing a system copy with SAPINST, we recently encountered a problem where the SAP Management Console would display the message "J2EE Status Info Unavailable" at the end of the dispatcher status. Then under the Java work process folder, the message "No Info Available" would show up. The exact error messages will depend on your kernel version, but you get the point.
After countless hours pulling out my hair and working with SAP support, we finally discovered the issue. Apparently something went wrong with the Java extract from the source system, so settings were not transferred correctly to the extract files, and thus the target system was populated with erroneous information. Unfortunately, everything from my standpoint was showing to be correct and successful with the system copy. I was only able to correct the problem by returning to the source system and running a new System Copy, utilizing the "database specific" option so that SAPINST only ran the Java migration steps. I then went to the source system and re-ran the system copy target steps, and pointed it to the new Java Migration files.
Worked like a charm.
Hope this helps...
