Upgrading our BW 3.0A to 3.0B

Question:
Hi all,
I’m trying to upgrade SAP BW from 30A to 30B and after 60% of the upgrade phase in ACL_620, the system wait long time.
I check the processes in the windows task manager and the CPU usage was 100% and the process oracle.exe used 99%.
What I have to do?
Thanks in advance,
Carlos Pereira
Answer:
You can check the logfiles on OS level. If the time stamp of the current log file is changing from time to time, the phase is still active. I had the same problem. The ACT_620 was running for several hrs, but the logfiles were still active.
If not: As far as I remember they say what to do in the installation/upgrade guide
