2.2.3 userApplication Creation

Operating userApplication is configured as follows:

Scalable operation with Oracle9i RAC

userApplication	Description	Resources
app1,app2	Controls Oracle instances and listeners. It is created on each node.	Oracle resource (instance, listener) Gds resource
app3	Starts up or stops userApplication (app1 and app2) simultaneously on all nodes. (Option)	Controller resource
app4,app5	Used as standby for Gls or takeover network. (Option) Create them according to operating conditions.	Gls resource, etc

Information

The following setup values are recommended for app1 and app2. The other attributes not described below are optional.

Attributes	Values
Operation method	Standby
AutoStartUp	Optional If you control userApplication startup and stop on all nodes by using the controlling userApplication, be sure to specify No.
AutoSwitchOver	No
PersistentFault	1

Standby operation

userApplication	Description	Resources
app1	userApplication on all operation nodes	Oracle resource (instance, listener) Gds resource Fsystem resource Gls resource

Information

The following setup values are recommended for userApplication app1. The other attributes not described below are optional.

Attributes	Values
Operation method	Standby
AutoSwitchOver	HostFailure\|ResourceFailure\|ShutDown
PersistentFault	1
HaltFlag	yes

The flow of userApplication creation is as follows:

1	userApplication with No Oracle Resources userApplication Operation Check	2.2.4 2.2.5 2.2.6
2	Oracle Database Creation and Setting	2.2.7
3	userApplication with Oracle Resources userApplication Operation Check	2.2.9 2.2.10 2.2.11 2.2.12

Information

PersistentFault remains the same resource status (Faulted) even after RMS is restarted in the event of a resource failure. Users are supposed to locate the fault and check completion of recovery processing then start userApplication manually. For example, if a failure occurs, users can detect which userApplication failed even after server reboot. Even though AutoStartUp setup is set, userApplication will not be started, and automatic startup will prevent recurrence of the failure.
