MaxDB Upgrade, unable to establish DB instance session

636 Views

Hi all, I am trying for to perform a SAP DB upgrade from 7.3.0.28 to version 7.5.0.21. My problem is that when I execute command SDBUPD the following messages appear on screen almost immediately and the update is terminated:

beginning to check sap db instances

start new instance update

cannot establish database instance session

I followed the instructions in the upgrade guide and notes mentioned but this issue is nowhere mentioned. I am not a database specialist so any help and/or suggestions are more then welcome.

Thanks in advance, Tiest
