Setting the RESUMABLE_TIMEOUT Initialization Parameter

You can specify a default system wide timeout interval by setting the RESUMABLE_TIMEOUT initialization parameter. For example, the following setting of theRESUMABLE_TIMEOUT parameter in the initialization parameter file sets the timeout period to 1 hour:

RESUMABLE_TIMEOUT  = 3600

If this parameter is set to 0, then resumable space allocation is disabled even for sessions that run an ALTER SESSION ENABLE RESUMABLE statement without a timeout value.

You can also use the ALTER SYSTEM SET statement to change the value of this parameter at the system level. For example, the following statement disables resumable space allocation for all sessions that run an ALTER SESSION ENABLE RESUMABLE statement without a timeout value:

ALTER SYSTEM SET RESUMABLE_TIMEOUT=0;
