Hi all, I am trying for to perform a SAP DB upgrade from 220.127.116.11 to version 18.104.22.168. 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
