EHP 7 upgrade - Got stuck at Pre-processing - urgent help required
I am upgrading my current ECC 6 EHP 6 system to EHP7. I got stuck in the Pre-processing phase "imports included Add-on and Support Packages into the shadow tables and the new tables". there is no error but it is runnign for more than 15 hours now. i dont even see a latest log showing its progress. The logs got updated 14 hours ago and there is no update after that.
The shadow instance was down. Main instance is up and running and no Jobs running. I manually started the shadow instance and checked if that will help . but no use. so restarted the SUM tool. it gives a different problem now. I have listed out the current probelms below. please check and advise
1. SUM tool shows, "ABAP- Starting handshake" - SAPUP.Out erro message (ERROR in GUI communication: Error in network interface: NIEINVAL (0/53 written))
2.Shadow instance up and running but while trying to login from GUI,it says "rabax during SAPGUI logon". i can see all its WP in 'waiting' status at the OS level
3.in DB02, "oldest Open Transaction" shows Aug 15 2014 10:30 PM, which means this transaction is there at the DB level for more than 16 hrs now.
Please help trouleshoot and resolve this. useful inputs will be rewarded immediately
