Table 3 Variable or Parameter Name in haoracle.conf file (continued)

MAINTENANCE_FLAG

This variable will enable or disable maintenance mode for the Oracle database

 

package. By default this is set to "yes". In order to disable this feature

 

MAINTENANCE_FLAG should be set to "no". When Oracle Database or ASM needs

 

to be maintained, then a "<package directory>/Oracle.debug" file needs to be

 

touched. During this maintenance period Oracle database or ASM instance's process

 

monitoring is paused. Even if an Oracle instance is brought down, its package will

 

not be failed over to the standby node. To continue monitoring and come back from

 

the maintenance mode, remove the Oracle.debug file. It is the user's responsibility

 

to ensure that Oracle instance is properly running after the maintenance phase.

 

NOTE: Setting MAINTENANCE_FLAG to "yes" and touching the Oracle.debug

 

file in the package directory will put the package in toolkit maintenance mode.

 

Serviceguard A.11.19 release has a new feature which allows individual components

 

of the package to be maintained while the package is still up. This feature is called

 

Package Maintenance mode and is available only for modular packages. For more

 

information using Package Maintenance mode, see Modular package support in

 

Serviceguard for Linux and ECM Toolkits available at http://www.hp.com/go/

 

hpux-serviceguard-docs—>HP Serviceguard Enterprise Cluster Master Toolkit.

 

If the Oracle database package is dependent on the SGeRAC clusterware package

 

(OC MNP), then the Oracle database package will automatically go into toolkit

 

maintenance mode if the SGeRAC OC MNP is put into toolkit maintenance mode. To

 

put the SGeRAC OC MNP into toolkit maintenance mode, its MAINTENANCE_FLAG

 

attribute must be set to 'yes' and a file oc.debug must be created manually in the

 

OC MNP working directory on that node. More details about how to put the SGeRAC

 

OC MNP package in toolkit maintenance mode can be found in the SGeRAC toolkit

 

user guide. If the MAINTENANCE_FLAG attribute of the SGeRAC OC MNP is set to

 

'yes', this parameter must also be set to 'yes' in the single-instance Oracle database

 

package.

ORA_CRS_HOME

This parameter must be set only in case where Oracle database packages created

 

using ECMT Oracle toolkit and SGeRAC packages run in the same cluster. This

 

parameter must be set to the Oracle Clusterware home directory.

MONITOR_INTERVAL

The time interval script (in seconds) will wait between checks to ensure that the Oracle

 

instance is running. Default value is 30 seconds.

TIME_OUT

The amount of time, in seconds, to wait for the Oracle abort to complete before killing

 

the Oracle processes defined in MONITOR_PROCESSES. The TIME_OUT variable is

 

used as protection against a worst-case scenario where a hung instance prevents the

 

package halt script from completing, therefore preventing the standby node from

 

starting the instance. The value of TIME_OUT must be less than the

 

HALT_SCRIPT_TIMEOUT value set in the package configuration file. If

 

HALT_SCRIPT_TIMEOUT is not defined then, it is the sum of all the

 

SERVICE_HALT_TIMEOUT defined in the package. This variable has no effect on

 

the package failover times.

PARENT_ENVIRONMENT

This is used to mention if the Oracle user's shell should be invoked as a new shell or

 

as a subshell that inherits the variables set in the parent shell. This can be set to only

 

yes or no. Set to 'yes' if the Oracle user's shell should be invoked as a subshell. Set

 

to 'no' if the Oracle user's shell should be invoked as a new shell. If set to no, the

 

Oracle user's profile file is executed and the variables set in this profile file are available

 

to the new shell.

CLEANUP_BEFORE_STARTUP This parameter indicates whether 'shutdown abort' needs to be executed before the startup of the Oracle or ASM instance. 'shutdown abort' ensures the cleanup of uncleared shared memory or semaphores. This parameter can be set to only 'yes' or 'no'. Default value is no.

USER_SHUTDOWN_MODE

This parameter is used to specify the database shutdown mode only when a shutdown

 

is initiated by the user and not due to a failure of a service. This parameter can take

 

values "abort" or "immediate" only. If "abort" is specified, the database is shutdown

 

using the abort option. If "immediate" is specified, the database is shutdown using

 

the immediate option.

ALERT_MAIL_ID

This parameter is used to specify the e-mail address for sending alerts.
