Warm and emergency starts

When you use program autoinstall, the restart time depends upon whether you are using program autoinstall with or without cataloging.

If you are using program autoinstall with cataloging, restart times are similar to those of restarting a CICS® region that is not using program autoinstall. This is because, in both cases, resource definitions are reinstalled from the catalog during the restart. The definitions after the restart are those that existed before the system was terminated.

If you are using autoinstall without cataloging, CICS restart times are improved because CICS does not install definitions from the CICS global catalog. Instead, definitions are autoinstalled as required whenever programs, mapsets, and partitionsets are referenced following the restart.

See the Troubleshooting for recovery processing for information on cataloging.
