Address space dumps and transaction dumps

For some abends, an address space dump is produced. For CICS transactions, a transaction dump showing the storage areas of interest to the transaction is provided.

• If an application passes some data, the address of which is no longer valid, a dump is sometimes produced in the user's address space.
  Note:

  For a batch dump, the dump is formatted and written to SYSUDUMP. For information about SYSUDUMPs, refer to SYSUDUMP information. For CICS, a system dump is written to the SYS1.DUMP data sets, as well as a transaction dump being taken.

• If a problem with WebSphere MQ for z/OS itself causes an abend, an abend code of X'5C6' or X'6C6' is returned, along with an abend reason code. This uniquely describes the cause of the problem. Refer to WebSphere MQ for z/OS abends for information about the abend codes, and see the WebSphere MQ for z/OS Messages and Codes manual for an explanation of the reason code.
