Not being able to IPL from a loader general file (LGF). 2. When cycling from NORM to 1052 state, the system would take a CTL-E1 every 1 second from CDCP. 1052 state was never reached. The system would have to be re-IPLed to reach 1052 state. 3. Unable to build UF1T.ASM because the fixed file definition of the CDC record was not provided. SOLUTION: APAR PJ30137 addresses the following items: 1. The CDC_HEADER structure now contains a date in addition to the time stamp. 2. When writing to tape and the file system, one additional CDC_HEADER is written at the beginning of the record with its type filed = 0x93. This indicates the beginning of CDC record. The header will also contain the number of subsequent headers for the record. 3. A check for an LGF IPL has been added. 4. A check to make sure that CDC ECBs are created only in NORM state has been added. 5. CDC ECBs now have ecbptr()->ce1aii |= CCE1CYC; to prevent a CTL-E1 error during cycle down. 6. A check has been added to uf1t.asm to make sure that the DBDEF statements for CDC are assembled for the basic subsystem only. Stage 1 SIP generation with SYSSET.MAC and SYGKB.MAC is needed to pick up the change. 7. Corrected handling of the shutdown indicators in the CDC client and updated with the new CDC header structure. To correctly assemble uf1t.asm, TPFDF fixed file record #DCA0DF needs to be defined as follows: RAMFIL TYPE=4SA,RECNO=00036,RECID=#DCA0DF,DUPE=YES, X UFTI4=(51,1015),UFTI5=(51,1016) SIP has to be run to generate a new FACE table. If it is decided to not load UF1T, TPFDF co-requisite APAR PQ95747 should not be loaded.

MIGRATION CONSIDERATIONS: To correctly assemble uf1t.asm, TPFDF fixed file record #DCA0DF needs to be defined as follows: RAMFIL TYPE=4SA,RECNO=00036,RECID=#DCA0DF,DUPE=YES, X UFTI4=(51,1015),UFTI5=(51,1016) SIP has to be run to generate a new FACE table. If it is decided to not load UF1T, TPFDF co-requisite APAR PQ95747 should not be loaded.
