Memory allocation request for image backup operation was
refused by the operating system.
Explanation
TSM requires access to memory in order to store
information about used blocks of a file system. In this case, more
memory was requested than the operating system would allocate.
System action
If imagegapsize is too small for a dedicated
filesystem and TSM faces out-of-memory condition then TSM automatically
switches to full volume backup. Operation continues with imagegapsize
= 0.
User response
Some recommendations to avoid the out-of-memory
condition:
- check to see if the memory resource limit is too low by entering
the following command: ulimit -a Then you can ask
the UNIX system root user to
increase memory limit.
- increase the value of the imagegapsize option. The bigger imagegapsize
is used, the less memory is needed for image backup, but more unused
data is sent to server. And vice versa: the smaller imagegapsize
is used, the more memory is needed for backup, but less unused data
is sent to server. The outcome also depends much on how data is spread
on the volume.
