7 TimesTen Attributes for Oracle Clusterware

The attributes defined in this chapter are used to set up TimesTen active standby pairs that are managed by Oracle Clusterware. These 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.

List of attributes

This section lists the clusterware attributes in these tables:

Table 7-1 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 Oracle Clusterware resources

None


Table 7-2 Conditionally required attributes

Name Description Default

AppCheckCmd

Command line for checking the status of an application that is managed by Oracle Clusterware

None

AppName

The name of an application that is managed by Oracle Clusterware

None

AppStartCmd

Command line for starting an application that is managed by Oracle Clusterware

None

AppStopCmd

Command line for stopping an application that is managed by Oracle 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 data store is backed up.

None

SubscriberHosts

List of host names that can contain subscriber data stores.

None

SubscriberVIP

The list of virtual IP addresses that can be associated with subscriber data stores.

None

VIPInterface

The name of the public network adapter that will be used for virtual IP addresses on each host.

None

VIPNetMask

The netmask of the virtual IP addresses.

None


Table 7-3 Optional attributes

Name Description Default

AppFailoverDelay

The number of seconds that the Oracle Clusterware resource that monitors the application will wait after a failure is detected before performing a failover.

0

AppFailureThreshold

The number of concurrent Oracle 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 data store 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 Oracle 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 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 Oracle Clusterware waits for the monitor process to start before assuming a failure.
