Obsolete system initialization parameters

Table 1 shows those system initialization parameters that are obsolete.

Remove any of these obsolete parameters from your system initialization table, or from your CICS® startup JCL (for example, the SYSIN data set) before migrating.

Table 1. Obsolete system initialization parameters
Obsolete keywords Explanation
MAXHPTCBS Run-time support for Java™ program objects and hot-pooling (HPJ) has been removed. The system initialization parameter MAXHPTCBS is not required, and is removed. The open TCB mode H8, which was used for hot-pooling Java program objects and was controlled by MAXHPTCBS, no longer exists.
SSLTCBS This parameter is now obsolete and is only kept for compatibility. If it is specified, it is rejected with a message and MAXSSLTCBS is assumed.
TCAM This parameter is now obsolete and is only kept for compatibility. If it is specified, it is rejected with a message and TCAM=NO is assumed.

CICS Transaction Server for z/OS®, Version 3 Release 1 does not support the TCAM/ACB interface. It supports the TCAM/DCB interface indirectly.
