Heap Size Limit Environment variable

[bensonian]

Is there an Environment variable we can set at the Project level, to increase the 'heap size limit'. Please find the attached error message below:

The current soft limit on the data segment (heap) size (1610612736) is less than the hard limit (2147483647), consider increasing the heap size limit

Any help would be appreciated.

That's controlled by the operating system via the ulimit function. Have a chat with your SysAdmin and see if they're willing to bump that up for your user.

Thanks for a quick response. But, the current ulimit function is set to unlimited. I beleive this error is more specific to Datastage and its about some Environment variable which we are not too sure about.

How are you checking? You can't use "the same user" and check from the command line, you need to check from a job's environment. Take any job and add an "ExecSH" before-job call to "ulimit -a" and see what it logs... unless you've already done that?

Actually the abort we are encountering is in 'PROD' environment. Currently a 'batch id' was used to run these jobs. Being a user other than 'batch id' these are the results after executinng 'ulimit -a'.
