MaxDB 7.8 backup problem

[Former Member]

Hi guys,

        I'm facing problems with a MaxDB database 7.8 (7.8.02.21) 32 bits, installed in a Windows 2003 Server 32 Bits.

        The database has 1Tb and it was running fine until January/2015.

        There was a Microsoft Windows Security Patch applied in this server and, maybe by coincidence, the Database Backup COMPLETE and the Database Backup INCREMENTAL don't run anymore and return the error below:

              -915 No more memory 3,Data backup failed

        After this process the database status has changed to OFFLINE.

        Do you know a way to solve this problema?

Thanks in advance!

Hi Ricardo,

I guess, database performance is not one of your priorities, otherwise you would not be running a 1 TB database on a 32 bit OS 🙂

Please understand that Windows 32 bit can only address 4 GB of memory. My guess is that with the Windows security patch or due to other reasons, the memory consumption of the OS or other processes increased and so less is available for MaxDBs datacache to be allocated.
To workaround, there is no other option as to reduce the datacache size, which will reduce performance even more.

Of course, let stress that you should urgently move to a 64 bit OS and running a 64 bit MaxDB version. This would allow you to increase the datacache size to e.g. 32 GB depending on your available server memory...

Hi Thorsten,

        Thank you for you atention.

        I've created the new environment with a Windows 64Bits and MaxDB 64Bits but I'm facing problems with the migration.

        I put a new comment with the subject: "Restore - MaxDB 7.9".

        Could you please take a look ?

Thanks a lot!!!
