The default setting for the ENCRYPTION system initialization parameter has changed to STRONG. If you have no high encryption ciphers installed (security level 3) on z/OS®, then you need to downgrade the default setting for the ENCRYPTION system initialization parameter. The NORMAL setting that has been used as the default in previous releases, has changed to MEDIUM for this release of CICS®. For migration purposes, NORMAL is accepted as an alternative to MEDIUM.
The SSLTCBS system initialization parameter is now obsolete and has been replaced by MAXSSLTCBS. MAXSSLTCBS controls the maximum number of S8 TCBs that are allowed to run concurrently in the open transaction environment (OTE) TCB pool for SSL.
