Better workaround for S_ACCELERATOR_M9 SQL Server bug
For those upgrading to IP 17/18 on SQL Server you will face bug
IP2017 Production Mode Upgrade Failing with Duplicate Key on _M9 indexes, SQL Server (Doc ID 2376204.1)
BUG:27616636 - DUPLICATE KEY ERROR ON _M9 INDEX IN PROD MODE UPGRADE ON SQL SERVER
We ran into the same bug and don't like the workaround suggested and are providing what we think is a better work around. The problems with the suggested workaround are these:
- Running the dev upgrade sequence in production will add hours of downtime you don't want. E.g. instead of the upgrade running two hours now it will run 10 hours.
