The MULTIPLE ENCLAVE feature is a performance enhancement for the support of LE/370 COBOL programs running under CA-IDMS/DC. It enables multiple programs running under the same CA-IDMS/DC task to share the same LE enclave, thus reducing CPU consumption and storage usage.
As described in the above appendix, only some programs are eligible for the MULTIPLE ENCLAVE feature. Therefore, when defining a DC-COBOL program to the CA-IDMS System Generation compiler, you must specify whether the program is to run with MULTIPLE ENCLAVE ON or OFF.
If you define a program that is not eligible for the MULTIPLE ENCLAVE feature as ON, then at runtime the task will abend with a UFF3 with reason code 0007. Unfortunately, neither the abend message nor the place at which the task abends will necessarily indicate which program has caused the problem.
