Schema versions

Schema versions are used to provide the greatest compatibility with your systems.

The schema version is identified by a version and release number shown in the schema; for example a schema version of 2.0 is expressed in the schema as:
CICSEPSchemaRelease="0" CICSEPSchemaVersion="2"

The schema version number is incremented at each CICS® release, if the release contains a new schema. The schema release number is incremented when a new schema is introduced by the IBM® service organization. You can display the highest supported schema level by entering the CEMT INQUIRE EVENTPROCESS command.

The CICS event binding editor keeps your schema at the lowest level possible to provide the greatest compatibility with systems that might not support later schema versions. The CICS event binding editor sets the version and release numbers in the evbind file to the minimum level for the options chosen by the user. If the event binding file is using a later schema version than the schema version supported by CICS, the installation of the event binding file fails. If a feature is not listed in Table 1 it is a base feature with a minimum schema level of 1.0.
