Special Product Considerations
Review the following considerations before installing the product:
Installation Consideration
- If the installation data sets have been loaded to a cataloged data set with an HLQ other than IBM.fmid, the SMP/E RECEIVE command must change the HLQ by specifying the RFPREFIX(hlq) parameter, for example, RECEIVE SELECT(HDGA620) RFPREFIX(hlq).
Exits Considerations
- Sample source code for Stage 1 Signon Security exit (DGACXSIG in SDGASAMP) and Stage 2 Security exit generation macro (DGASECUR in SDGASAMP) have been renumbered. Verify line numbers before applying any SMP/E USERMOD or custom code changes. For changes to Signon Dummy Passwords, refer to Global Signon Defaults.
- The IBM® Connect:Direct® startup JCL has a user-definable DD statement (USRINFO) for displaying user-defined information from User Exits. If the USRINFO DD is allocated, then IBM Connect:Direct opens it during product initialization and initializes it with the string SITA523I USRINFO INITIALIZED.
Initialization Parameters Considerations
-
In a IBM Connect:Direct/Plex environment, if you specify ANYADDR or ANYADDR6 for the TCP.LISTEN local initialization parameter associated with a IBM Connect:Direct Server but do not specify the CDPLEX.REDIRECT parameter, a default address is created as the IBM Connect:Direct/Plex redirection address. For the IPv6 protocol, the default is generated by adding a::FFFF: prefix to the IPv4 default. If you do not want this to be your default address, specify the value you do want using the CDPLEX.REDIRECT parameter.
If you use the dynamic VIPA resources, you may need to specify the SOURCEIP parameter in the network map if the remote node cannot perform network map checking. The SOURCEIP address is used to bind the socket and by the remote node to perform netmap checking.
- The following initialization parameters are obsolete and must be removed from the initialization parameter file:

| ZEDC.EXCLUDE | ZIIP.EXTCOMP.DATASIZE.THRESHOLD | |
Process Retention Considerations
- To enable Process Retention, increase the TCQ space before activating it. A Process is retained in the PR queue until manually deleted, space is required, or MAX.AGE value is reached. Increasing TCQ space reduces the likelihood that a Process in the PR Queue is automatically deleted when space is required. For information on enlarging the TCQ, see Planning the Installation.
Network Map Considerations
- If IBM Connect:Direct FTP+ for z/OS communicates with an earlier version of IBM Connect:Direct for z/OS®, the CDFTP.TEMPFILE specification in the netmap must be an zFS file unless appropriate maintenance has been applied to that version of IBM Sterling Connect:Direct for z/OS.
- Session Management of Adjacent Nodes - Use the SESS.SNODE.MAX network map parameter only with the TCP/IP and LU6.2 protocols.
Storage Considerations
- To maximize available storage below the 16-MB line, define sufficient
storage above the 16-MB line, and maximize concurrent processing,
define a region size of 0 MB for IBM Connect:Direct.Note: Depending on your system-specific storage requirements, the MAXTHREADTASK and MAXASSIZE parameters in SYS1.PARMLIB member BPXPRMxx may also have to be altered to ensure maximum storage and concurrent processing within IBM Connect:Direct.
