Hi Experts,

Where can I find the Environment variable "APT_LUTCREATE_NO_MMAP" ?
I dont see it in the Usual list of Env Variables that we find the Administrator Client.

Do I need to import this from else where? Please help.

regards,

APT_LUTCREATE_NO_MMAP is one of the environment variables that are not exposed in DataStage Administrator client.

Simply add an entry for the variable in DSDesigner at job level and set this variable to True (or 1).

Oh... Thanks for thar quick response Roland

.

So I have created just a normal parameter with the name and prompt as "APT_LUTCREATE_NO_MMAP" of type 'String' and given the value as "True".

Will test the jobs and revert with the result.

Basically our server is performing very slow and thus trying some things out to Improve the performance.

Thanks again.

You need to create the environment variable (using DataStage Administrator client) and bring that into the job as a parameter. The parallel execution engine is looking for an environment variable.
