OCUM 5.2 CORE (7-Mode) on Linux - SQL Startup Error

[ Edited ]

We had abnormal shutdown of the OCUM core Linux based server couple of times.

Right after that DFM service couldnt start successfully.

 

Basically customer did the kernel upgrade and rebooted the server without stopping DFM services properly. Second time they rebooted again without stopping the services.

 

Now we are getting this error in logs:

Seems like This is the actual error

 

"Assertion failed: 201865 (16.0.0.2087)

Checkpoint log: Invalid pages at 0x74bb9 and 0x74c63"

 

Could someone please help us into this ?

 

Re: OCUM 5.2 CORE (7-Mode) on Linux - SQL Startup Error

If you have a backup for the DFM server (.ndb file) captured before the host upgrade, safeguard it - you may need it as a restore option.

Open a case with Support - the database itself (monitordb.db) will need to be investigated to determine the details behind the page faults.
