Grid Infrastructure upgrade from 12.2 to 19.8 succeeds but ASM won't start -- Problem and Solution
Just updating this discussion to say I completed the upgrade after submitting an Oracle Support Request and, with their help, determining their is a bug in the 19.8 grid upgrade. This was an Oracle restart grid infrastructure on a single instance install. The orarac19.dll in the bin directory should remain in a disabled state by being renamed something like orarac19.dll.dbl. However, the following procedure results in the dll being enabled (renamed orarac19.dll):
- Install 19.3 grid software only
- Patch grid home to 19.8.0.0.
- Run gridSetup.bat to upgrade 12.2 to 19.8 grid home.
Before running the upgrade, I ensured the orarac19.dll.dbl existed in both the 12.2 and 19.8 grid homes. After upgrade the extension was removed from the dll and Real Applications Clusters was enabled. ASM would not start.
