DWW0655S

Log dddd has an invalid BB setting. For first block in a sequence the only valid settings are X'00' and X'01'. The actual setting is xx.

Invalid BB settings were detected while reading a queued sequential access method (QSAM) copy of an MVS™ log stream. The settings could be invalid for one of these reasons:
  1. The flag bits have a value that should never appear.
  2. A block that was expected to begin a sequence of QSAM blocks forming a log stream block does not have the flag value of X'00' or X'01'.
  3. A block that was expected to be part of a split log stream block did not have the flag value X'02' or X'03'.
Here are the explanations of the hex codes:
00 The MVS™ log stream block was not split.
01 The MVS™ log stream was split. Subsequent QSAM blocks are part of the same MVS™ log stream block.
02 More QSAM blocks that are part of the same MVS™ log stream block exist.
03 This is the last QSAM block of the MVS™ log stream block.

CICS® VR processing stops.

Make another copy of the MVS™ log stream using a different block size. If the problem persists, contact your local IBM® Support Center.
