MaxDB full backup failure: RTEMem_Allocator : could not allocate memory

[Former Member]

Hello,

The version of Maxdb is 7.5.00.52, O.S is 2003 32bit with 4GB physical memory. The database space is approximately 4 TB.

Recently the backup on disk and the backup with external storage fails with the following error:

0x1480 ERR 54008 MEMORY   RTEMem_Allocator : could not allocate me

Build 052-123-232-633

I checked out some parameters which CACHE_SIZE that is currently set at 260000.

When we tried to change it to lower values the resource MaxDB never went online.

Dear all,

To close the problem it was necessary to migrate the platform to 64-bit and apply the parameters of memory in the right way....

Hello Emiliano,

If you are an SAP customer, goahead and create an SAP message describing the above issue and attach the database logs in the RUN directory.

Attach all the /sapdb/data/wrk/<sid>/dbm*  files, Knldiag* to the message.

It looks like the runtime memory allocater is not able to allocate the memory, but we need to check the database logs to determine the root cause of this problem.
