Error description
Transactions are entered to CICS through the VSE console using MSG F2,DATA=CEMT INQ TAS commands. However, some of the CEMT transactions never start. . EVA100 in DFHEVA10 is the CICS OC exit routine (Operator Communications exit). EVA100 runs whenever a VSE MSG for the partition console is issued, and passes the data on to the subtask in a console input buffer (CIB). Parameter CIBVMAXN controls the number of CIBs obtained during startup, and is hardcoded to 64 (decimal). The CEMT transactions are sometimes dropped when the number of messages exceeds this CIB count. . Change Team provided a testfix to increase CIBVMAXN to 128, and this resolves the problem. Customer is also requesting a WTO informational message when CICS drops a transaction, rather than to just ignore the MSG and exit. VSE may also have same problem. See DY46353.

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: MSG commands sent to CICS using the * * VSE console may be lost. * **************************************************************** * RECOMMENDATION: * **************************************************************** When a MSG command to a partition running a CICS system is entered from a VSE console the Operator Communications Exit, EVA10O, is invoked to process the command. The input is passed to the messaging subtask in a Console Input Buffer (CIB). The number of CIBs available is determined by CIBVMAXN, which is currently hardcoded to 64. If all the CIBs are already in use the input message will be ignored, without notification. Note that VSE apar DY46353 fixes a problem with similar symptoms.

Problem conclusion
The number of CIBs getmained at CICS initialization has been increased to the current maximum possible, 255.The storage used for the CIBs will now be above the 16M line. A new message DFHEV5010I will be issued if there are still not enough CIBs to process a command. The CICS transaction Server for VSE/ESA V1.1 Messages and Codes GC34-5561-07, will have new message DFHEV5010I added to section 1.24 as follows: DFHEV5010I CICS is busy. VSE MSG command has been rejected. Explanation: CICS cannot accept the MSG command as 255 MSG commands to invoke transactions are currently queued. System Action: CICS rejects the MSG command. User Response: Reenter the MSG command. Destination: Console Module: DFHEVAS
