SQL2022 CU12 Question

  • Hi.

    I installed SQL2022 CU12 and in the notes it says:



    Fixes an issue in which the sp_server_diagnostics stored procedure doesn't respond to the Always On availability group (AG) resource DLL within the HealthCheckTimeout when the I/O takes a long time, which causes unnecessary restart and failover. For example, when the sp_server_diagnostics stored procedure is waiting for the PREEMPTIVE_OS_GETFINALFILEPATHBYHANDLE wait type.

    Note: To apply this fix, you need to turn on trace flag 16301, which is off by default. Tracing is added for this event regardless of the trace flag.


    I added the flag to startup on my primary and both secondary's. Is that correct - it's not just the primary is it?

    Can't find any info on this.
