Graceful switchover terminates with an error:
- `Unable to load the shared library "orasrvmhas12.dll"or a dependent library`
This error might be seen with Oracle Database releases 12.2 and above on Windows based platforms.
The Oracle Instant Client libraries for Dbvisit Standby Version 8 and 9 are 12.1
This is to cater for Oracle Database version 10.2 and above.
If you encounter this error, there are potentially two workarounds available.
Note: This issue is fixed in Dbvisit Standby Version 10, where it provides an option to choose Oracle Instant Client version 12.1 or 12.2
Go to %DBVISIT_BASE%/standby/lib directory
rename file orannzsbb12.dll to orannzsbb12.dll_norun
Replace the Instant client libraries in %DBVISIT_BASE%/standby/lib with the 12.2 instant client equivalent files.
