DFHZC2424 E date time applid termid tranid SESSIONC command request invalid. sense ((instance) Module name: {DFHZSES | DFHZSES | })

Explanation

A SESSIONC request is incomplete or invalid. Possible reasons are as follows:

  1. The TCTTE was altered.

  2. The command request bits are incomplete. DFHZSES checks TCTEISDT for a Start Data Traffic (SDT) command, TCTEISTS for a Set and Test Sequence Number (STSN) command, and TCTEICLR for a CLEAR command. If it does not find any of these, DFHZSES causes the message to be issued.

  3. The wrong request was queued to SESSIONC.

This imbed is inserted in DFHZC xxxx messages with sense inserts. For the meaning of sense , see message DFHZC2400.

System action

All outstanding send and receive requests are purged. If a task is attached, it is abnormally terminated with a transaction dump.

Message DFHME0116, which contains the symptom string for this problem, is produced.

Communication with the node is terminated by issuing the VTAM CLSDST macro instruction.

User response

Ensure that application programs running concurrently do not alter the TCTTE.

If the TCTTE is not altered, check for conditions 2 or 3.
