Dear Techies,
Request inputs on the current issue mentioned below for an SAP upgrade activity facing currently.
We are performing ECC EHP upgrade on Dev. system and there is issue of performance of upgrade speed.
overall upgrade is running very slow (running for last 14 days)
SHADOW_IMPORT_INC phase running for more than 10 days, there are no errors observed in upgrade and OSS message raised for the same.
The infrastructure environment is Apps server Suse Linux 11 SP2 on VMware.
Database - Oracle 11.2 on RED-HAT 6.0 Linux on RAC+ASM VMware
Oracle has suggested to check the solution on native OS and they suggested note 1173954 which says Oracle has not certified any of its production on Vmware virtualized environments.
We did the upgrade on single host Sandbox system which was on standalone Vmware server, (SAP+DB on same server) .It was completed within 4 days or regular timeline and no issues observed there.
Your inputs on the current query will help a lot.
