CICS Load Module Size

CICS Load Module Size

CICS Load Module Size

I know that with CICS TS 1.3, there is a 16MB limit on the size of the load module.  Is this limitation still there with CICS TS 2.2 also?


RE: CICS Load Module Size

The load module resulting from any application program can occupy up to two gigabytes of main storage. Clearly, there is an extra cost associated with loading and initializing very large load modules, and CICS dynamic storage limits (EDSA) would need to be set correspondingly high. You should, if possible, avoid the use of large load modules. However large applications written in an object-oriented language, such as C++, can easily exceed 16M in size. Experience with C++ classes bound into a single DLL is that performance of the classes is degraded if the single DLL is reorganized into two or more DLLs. This is due to the processing required to resolve function references between multiple DLLs.
