Preallocate Required Control-M/IOA Files in TSO Logon Procedures

If entry to the Online facility is slow due to allocation problems, consider pre-allocating the required Control‑M/IOA files in the TSO Logon JCL procedure, instead of in the Control‑M/IOA CLISTs. JCL allocations are faster than TSO dynamic allocations. However, you should only consider doing this if there is no other way to speed up MVS allocations at your site.
