Hash file memory

Post by vikas gupta »

enabled Pre_load file to memory in hash file and I updated Read cache and write cache to size 999MB

Then also I got following error

Error: add_to_heap() - Unable to allocate memory :?:

Depending on your brand of UNIX and its configuration there are some limitations on how much memory you can allocate, not a DataStage limitation but a UNIX restriction.

Hi,
the warning you get implies that your expiriancing 1 of 2 things:
1. you actually run out of available memory while this event was logged.
2. your process exceeded the resource limit specified in the kernel for a single process.

usually when it happens its the later of the 2.

consult your sys admins for extending process resources in order to avoid such warnings.

IHTH,
