Maximum number of DataStage Jobs in a project

Filesystems can have a hard limit on number of subdirectories that can be contained in a directory, for example 32766 (32K -2) for Linux

For every job, DataStage will create hash files as subdirectories in the project directory. Here is a list of the subdirectories created for every job. In this list "nn" represents the number (or id) of the job:

DS_TEMPnn

RT_CONFIGnn

RT_STATUSnn

RT_LOGnn

RT_BPnn

RT_BPnn.O

RT_SCnn (only for parallel jobs)

The folders have been created for jobs -- 

Parallel Job - 07

Server Job - 06

Our assumptions are below  --

Total sub directories can be created is - 32766
Project threshold - 80   
No of Parallel job can be creates is -   32766/7 - 80  ~ 4600
No of Server job can be creates is -   32766/6 - 80  ~ 5380

where 80 is for overhead of project default directory. In practice, the number might be smaller due to subdirectories not counted above, such as directories created by QualityStage jobs, some project folders etc.

This is just approximated calculation, variables can vary system to system.
