627: INCORRECT_SVC_LEVEL

The release level of the CICS® SVC (DFHCSVC) is not the same (or higher) than the release level of the external CICS interface.

System Action

The Initialize_User request is terminated. This error occurs before the external CICS interface SDUMP facilities are initialized, therefore EXCI issues an MVS abend (U0407) to force a SYSMDUMP.

User Response

Determine the level of the CICS SVC being used and ensure it is the same release level as the external CICS interface, or higher. If the SVC number is allowed to default (CICSSVC=0 in DFHXCOPT), the SVC number being used is the SVC first used by a CICS region on the MVS image. That is, the SVC used by the first CICS region to open the CICS interregion communications (IRC). If the SVC number is specified on CICSSVC in DFHXCOPT, the SVC number specified is at an incorrect level. For more information, see the description of the CICSSVC parameter in Using the EXCI options table, DFHXCOPT.
