Recovery of 7.8 MAXDB BACKup into MAXDB 7.7 instance problems

[jack_park]

I attempted a recovery in a MAXdb 7.7 DB using a Backup file from a 7.8 Maxdb installation. The backup logs show "OK" for the restore, but the MaxDB will not come back online. Below are the error logs from when I try to restart. Whats the best action to take to do: a recovery with another backup file of a 7.7 Max DB instance (same version)? If so, should it be a standard recovery or a recovery with initialization?

Hello,

I attempted a recovery in a MAXdb 7.7 DB using a Backup file from a 7.8 Maxdb installation

This is strange for me.

I think due to software release difference, you get this error -

ERR Admin 20017: RestartFilesystem failed with 'System error: unexpected error',_FILE=Kernel_Administration.cpp,_LINE=425 2011-10-14 11:42:11 ERR Kernel 20000: Assertion of state The software version is too old failed!,

Thanks

That statement is present in the log, I cut it out:

LINE=425 2011-10-14 11:42:11 ERR Kernel 20000: Assertion of state The software version is too old failed!,_FILE=Kernel_Migration.cpp

Plus:

The persistent version is : Version = 7.8.1.14

Does that help?

I haven't worked that much in MaxDB but I suspect if restoring a MaxDB 7.8 on maxDB 7.7 will work.

I think you should try backup/restore with same MaxDB version.

Thanks

Hi Jack,

>> Recovery of 7.8 MAXDB BACKup into MAXDB 7.7 instance

It is not possible
