MailStream Plus™ (MSP) can ran multiple jobs at the same time.
It is important to confirm that all the different jobs use different output names and different work file names.
(One exception is the MSETCI file. There is only one of those because that file is used to keep track of the Intelligent Mail serial numbers assigned to Sacks, Trays, and Pallets. All jobs should be using the same MSETCI file.)
Users can refer to the Installation Verification test job, which is installed with the software, to see how file names are assigned. Depending on the computer platform being used, the default job name is ivp.bat (Windows), ivp.job (UNIX/Linux), IVPFILE (z/OS), or @IVP@ (IBMi).
The only limitations would be the computer system's resources for memory, and the space available for writing output files and for temporary sort and work files.
