Need to know what MAES stands for, and what is its significance to CA Aion Business Rules Expert?
In the "CA Aion Business Rules Expert Installation Guide", Chapter 1, page 9, it states:
CA Aion Multi-Tasking Aion Execution System (MAES)
Note: The term MAES continues to be employed by internal programs and JCL for compatibility purposes. Wherever MAES is mentioned in documentation, it refers to the CA Aion Multi-tasking Aion Execution System.
As for the significance of MAES to CA Aion Business Rules Expert, the document "CA Aion Business Rules Expert Mainframe User Guide" chapter 5 page 171 states:
The CA Aion BRE Multitasking Aion Execution System (MAES) permits access by multiple users to a single Aion application in a shared address space.
MAES is started up using JCL, as described on page 174.
The MAES PROC is used to start the MAES region. Start MAES by submitting the installed MAES PROC JCL to z/OS. CA Aion BRE provides the sample JCL that you can use to start MAES. This JCL is supplied in the MAES member of the Aion PROCLIB.
To ensure adequate performance, set the MAES parameters to be equal to those of the CICS/VS or IMS/VS region with which MAES is communicating, and make MAES non-swappable. To customize your MAES startup JCL, use the instructions that follow this sample.
Note: MAES PROC resides in <aionhlq>.PROCLIB and the JCL to execute this PROC resides in <aionhlq>.MAES.JCL(MAESJOB).
