IMSPLEX=ccccc parameter for procedures
Use the IMSPLEX=ccccc parameter in procedure to specify the 5-character IMSplex group name, left-justified and padded with blanks, if necessary.
The IMSplex group name is passed to the SCI registration exit routine DSPSCIX0. The sample version of DSPSCIX0 shipped with IMS returns the value that you supply to DBRC as the IMSplex name.
Restriction: If you want to use Automatic RECON Loss Notification but you are not going
to use DSPSCIX0, you must add the IMSPLEX= keyword and its value to the DBRC procedure. You must
also manually ensure that all IMS instances that use the
procedure are in the same IMSplex. This is because the z/OS®
START command that IMS issues internally does not include an
IMSPLEX= value.
Recommendation: Use the SCI registration exit, DSPSCIX0.
