#

#"run_script_timeout" is the number of Seconds allowed for package to start.

#"halt_script_timeout" is the number of Seconds allowed for package to halt.

run_script_timeout600

halt_script_timeout700

Note:"halt_script_timeout" has to be more than the sum of

all the individual "service_halt_timeout"s of the "service_cmds". In SGeRAC toolkit this value is 600, by default.

Since the "service_halt_timeout"s for the service_cmds, "rac_check", and "dataguard_monitor" are each 300, a value larger than 600 has to be specified for "halt_script_timeout".

#file.
