Backup

Tomasz SuderDec 18 2024 — edited Dec 18 2024

Hi Everyone,

We are using Oracle 19 with patch like below On Windows 2016.

35681552;Windows Database Bundle Patch : 19.21.0.0.231017 (35681552)

Very often We have backup issues of Oracle instances.

Backup are failing using Commvault and in Windows event log there is such event (id 12366, VSS):

An unhandled exception was encountered while processing a VSS writer event callback method. The VSS writer infrastructure is in an unstable state. Restart the service or application that hosts the writer.

Writer name: Oracle VSS Writer - <Oracle_Instance>
Writer id: {26d02976-b909-43ad-af7e-62a4f625e372}
Writer instance: {19f3a5ba-5dba-40f6-adcb-3bcdeeb1bb33}
Process command line: C:\Oracle\product\19.0.0.0\dbhome_1\bin\oravssw.exe <Oracle_Instance>
Process ID: 17512
Writer operation: 1000
Writer state: 0
Exception code: 0x4fff0007
Exception location: 02

I suspect it might be related with Oracle VSS writer. I have tried lot of things including fixing the whole VSS, reinstalling Oracle VSS writers, etc … but so far no success.

does anyone encounter such problem ?

Thanks,

Tomasz
