5 Clusterware Attributes for TimesTen

The attributes defined in this chapter are used to set up TimesTen active standby pairs that are managed by Oracle Clusterware. These clusterware attributes are set in the cluster.oracle.ini file. The ttCWAdmin utility creates and administers active standby pairs based on the information in the cluster.oracle.ini file.For more information about creating a high availability replication scheme, see Oracle TimesTen In-Memory Database TimesTen to TimesTen Replication Guide. Also see "ttCWAdmin".

List of attributes

This section lists the clusterware attributes in these tables:

Table 5-1, "Required attributes"
Table 5-2, "Conditionally required attributes"
Table 5-3, "Optional attributes"

Table 5-1 Required attributes

Name	Description	Default
MasterHosts	Lists host names that may contain master data stores in an active standby pair scheme.	None
ScriptInstallDir	Specifies the path to be used to store action scripts for Clusterware resources	None

Table 5-2 Conditionally required attributes

Name	Description	Default
AppCheckCmd	Command line for checking the status of an application that is managed by Clusterware	None
AppName	The name of an application that is managed by Clusterware	None
AppStartCmd	Command line for starting an application that is managed by Clusterware	None
AppStopCmd	Command line for stopping an application that is managed by Clusterware	None
AppType	The data store to which the application should link.	None
CacheConnect	Specifies whether the active standby pair replicates cache groups.	N
MasterVIP	A list of two virtual IP addresses that can be associated with the master data stores.	None
RemoteSubscriberHosts	A list of subscriber hosts that are not part of the cluster.	None
RepBackupDir	The directory to which the active master data store is backed up.	None
SubscriberHosts	List of host names that can contain subscriber data stores.	None

VIPNetMask	The netmask of the virtual IP addresses.	None

Table 5-3 Optional attributes

Name	Description	Default
AppFailoverDelay	The number of seconds that the Clusterware resource that monitors the application will wait after a failure is detected before performing a failover.	0
AppFailureThreshold	The number of concurrent Clusterware resource failures to tolerate before considering the active standby pair failed and recovering the backup. This attribute is ignored if the configuration does not use virtual IP addresses or if RepBackupPeriod is 0.	2
AppScriptTimeout	The number of seconds the TimesTen application container waits for the action scripts to complete for a specific application.	60
AutoRecover	Specifies whether an active master should be automatically recovered from a backup if both master data stores fail.	No
ClusterType	The type of cluster.	Active
DatabaseFailoverDelay	The number of seconds that Oracle Clusterware waits before migrating a data store to a new host after a failure.	60
FailureThreshold	The number of failures of resources that Clusterware can tolerate before giving up.	2
MasterStoreAttribute	A list of all desired replication scheme STORE attributes on master data stores.	None
MonInterval	An integer representing the number of seconds for the monitoring interval of processes that monitor an active standby pair.	5
RepBackupPeriod	The number of seconds between each backup of the active master data store.	0 (disabled)
RepDDL	A SQL construct of the active standby pair scheme.	None
RepfullbackupCycle	The number times an incremental backup occurs between full backups.	5
ReturnServiceAttribute	The return service attribute of the active standby pair scheme.	None
SubscriberStoreAttribute	The list of all desired replication scheme STORE attributes for the subscriber data store.	None
TimesTenScriptTimeout	The number of seconds that Clusterware waits for the monitor process to start before assuming a failure.	21600 (seconds, or 6 hours)
