Enabling the Dynamic Dictionary

There are no new CA JARS control statements required.

Dynamic dictionary support is enabled by adding three mandatory and one optional DD cards to the CA JARS JCL.

The mandatory DD cards are //CAIJSDIN for CAJ1CMU3 control statements, //SYSPRINT for CAJ1CMU3 messages, and //CAJRCTMP, which is used to pass the CA JARS dictionary updates back to CA JARS main processing from CAJ1CMU3. The recommended form of these statements is identified by arrows in the JCL below.

The optional DD statement, //CAIJSDCO, is discussed in the section, Saving Dynamic Dictionaries.

//CAIJSDIN in the JCL activates dynamic dictionary support:

• If //CAIJSDIN is coded, //SYSPRINT and //CAJRCTMP must be coded.
• If //CAIJSDIN is not coded, //SYSPRINT and //CAJRCTMP are ignored.

Even with dynamic dictionary support enabled, CA JARS must be started with a populated CA JARS dictionary in the dictionary file //CAIJSDCI. This is because there is no guarantee the first SMF 110 record encountered in a run will be the appropriate CICS dictionary SMF record. Monitor records that do not match a dictionary entry are discarded by CA JARS.
