IBM Connect:Direct IUI ABEND Dumps
When the IBM® Connect:Direct® abends, a system dump might be required for problem resolution. To obtain a dump of the TSO address space, allocate a SYSMDUMP DD to an appropriately defined data set, and run the ISPF with the TEST option. To send a dump of the IUI to a data set, allocate SYSMDUMP with DISP=MOD to account for the two dumps that IBM Connect:Direct produces.
To recreate an ABEND of the IUI to produce a dump, perform the following steps:
- Ensure that the SYSMDUMP DD is allocated.
- Reinvoke ISPF with the ISPF TEST command.
To allocate a SYSMDUMP DD, type the following TSO command where filename is a valid DSN name that has LRECL=4160, BLKSIZE=0, and RECFM=FBS.
TSO ALLOC F(SYSMDUMP) DA(filename) MOD
The system will determine blocksize, and will prevent short blocks. Generally, 110 cylinders on a 3390 device is enough space for an IUI dump.
- When the ABEND message is displayed, press ENTER to produce a dump. Two dump messages (and dumps) are produced. Press PF3/END to bypass the dump.
