This parameter specifies the time
interval in seconds for which a transaction manager (TM), resource
manager (RM) or sync point manager (SPM) should retry the recovery
of any outstanding indoubt transactions found in the TM, the RM, or
the SPM.
This parameter is applicable when you have transactions
running in a distributed unit of work (DUOW) environment. This parameter
also applies to recovery of federated database systems.

Recommendation: If, in your environment,
indoubt transactions will not interfere with other transactions against
your database, you might want to increase the value of this parameter.
If you are using a DB2 Connect™ gateway
to access DRDA2 application servers, you should consider the effect
indoubt transactions might have at the application servers even though
there will be no interference with local data access. If there are
no indoubt transactions, the performance impact will be minimal.
