This option specifies the number of seconds that REBUILD INDEX should wait when draining the table space or index. The specified time is the aggregate time for objects that are to be checked.
You can specify any integer from 0 to 1800. If you do not specify DRNWAIT or if you specify a DRNWAIT value of 0, BMC AMI Recover uses the value of the lock timeout subsystem parameter IRLMRWT.
You can override DRNWAIT installation option at run time by using the DRAIN_WAIT integeroption from the REBUILD INDEX command. For more information, see DRAIN_WAIT integerin SHRLEVEL.
