IBM SC34-7012-01 manual Indoubt options for distributed transactions, WAITTIME00,00,00dd,hh,mm

SPURGE({NOYES})

This option indicates whether the transaction is initially system-purgeable; that is, whether CICS can purge the transaction as a result of:

vExpiry of a deadlock timeout (DTIMOUT) delay interval

vA CEMT, or EXEC CICS, SET TASK(id) PURGEFORCEPURGE command.

The default is SPURGE(NO).

TPURGE({NOYES})

This option indicates whether the transaction is system-purgeable in the event of a (non-VTAM) terminal error.

The default is TPURGE(NO).

Indoubt options for distributed transactions

When defining user transactions that update remote resources, you can specify the following options for remote recovery purposes:

ACTION({BACKOUTCOMMIT})

Specifies the action to be taken when a failure occurs during two-phase commit processing, after the unit of work has entered the indoubt period.

If you’ve specified WAIT(YES), the action is not taken unless the interval specified on WAITTIME expires before recovery occurs.

Whether you specify BACKOUT or COMMIT is likely to depend on the kinds of changes made to resources in the remote system.

WAIT({YESNO})

Specifies whether a failed indoubt unit of work is to wait, pending recovery from the failure, to resolve its indoubt state, or whether CICS is to take immediately the action specified by the ACTION option.

Note: A WAIT(YES) option can be overridden by WAIT(NO) defined on an intrapartition transient data queue. If a TD queue that is access by a transaction specifies WAIT(NO), and the transaction specifies WAIT(YES), the TD queue definition forces the transaction to either backout or commit, as specified by the ACTION attribute on the transaction resource definition.

WAITTIME({00,00,00dd,hh,mm})

Specifies, if WAIT(YES), how long the transaction is to wait before taking the action specified by ACTION.

You can use WAIT and WAITTIME to allow an opportunity for normal recovery and resynchronization to take place, while ensuring that a transaction commits or backs out within a reasonable time. See the CICS Intercommunication Guidefor information about defining wait times for distributed transactions.
