Error description
Abend 0c4 in DFSCON20 during /ERE while processing a type12 log record. The 0c4 is due to the fact that CTBCNT contains zeroes and the CTB should point to the LTERM (CNT) while terminating a conversation. The abend is the result of the fact that the /Assign command that connected the LTERM to the NODE was not processed across the restart. This assign failed because at the point where the 02 log record was processed, the CTB4RESP bit was still on. The node and lterm were static blocks and prior to the 02 log record there was a 4021 with CTB4RESP set and this was followed by a CVCT and a 16 for signoff and a 63 for logoff. It was not a valid condition for the CTB4RESP to still be set.

Problem summary
**************************************************************** * USERS AFFECTED: All IMS V13 users entering Response mode * * transactions, conversation transactions or * * both, and issuing /ASSIGN commands in a VTAM * * environment. * **************************************************************** * PROBLEM DESCRIPTION: ABENDS0C4 in DFSCON20 during an * * Emergency restart when CTBCNT * * contains zeroes. * * * * This is a forward-fit of APAR PM77485. * **************************************************************** * RECOMMENDATION: INSTALL CORRECTIVE SERVICE FOR APAR/PTF * **************************************************************** An ABEND0C4 occurs in DFSCON20 during /ERE while processing a type12 log record. The abend is due to the fact that CTBCNT contains zeroes. The CTB should point to an LTERM (CNT) when the conversation is terminating. The abend is the result of the fact that the /Assign command that connected the LTERM to the NODE was not processed across the restart. When the 02 log record for the Assign was processed during restart, DFSICL70 detected that CTB4RESP bit was still on and rejected the command. CTB4RESP should have been reset during session termination. Since the Assign command was not processed correctly, this led to the subsequent abend.
Problem conclusion
GEN: KEYWORDS: *** END IMS KEYWORDS *** DFSCRPD0 has been modified to reset CTB4RESP when processing a 63 termination log record.
