HP Serviceguard Toolkit for Oracle on Linux User Guide Version A.12.00.00

5 Oracle toolkit features
Alert mail notification
This feature facilitates you to configure email address to get the alert notification from toolkit
package. Alert mails are sent to configured email addresses in case of failure scenarios. It can be
a resource failure or altogether database failure that results in package failure.
Toolkit sends an alert email with failure messages in the following scenarios:
• Listener failure.
Message: Oracle listener Listener1 failed in Oracle toolkit package Oracle_pkg on node
NODE1.
• Multiple listeners failed.
Message: Oracle listener Listener1 failed in Oracle toolkit package Oracle_pkg on node
NODE1.
Message: Oracle listener Listener2 failed in Oracle toolkit package Oracle_pkg on node
NODE1.
• Database hung.
If configured, alert mail will be sent for Oracle database hang detection. For example:
$SGCONF/scripts/tkit/oracle/tkit_module.sh oracle_hang_monitor 30
alert.
Message: Database hang detected in Oracle toolkit package Oracle_pkg on node NODE1.
• Toolkit package failure.
Message: Oracle toolkit package Oracle_pkg failed on node NODE1.
Cluster verification feature for Oracle toolkit
Cluster verification is a proactive mechanism to identify cluster inconsistencies that adversely affect
toolkit package failover to an adoptive node.
Advantages of cluster verification
The important advantages of cluster verification are:
• To identify inconsistencies in Serviceguard and the Oracle toolkit resources across package
nodes before you create and configure the Oracle toolkit package.
• To automate the process of validating certain attribute values specified in the package
configuration file.
• To achieve complete validation of cluster and application toolkit using single command
execution.
• To build a steady cluster for high available solution.
NOTE: The verification for the Oracle configuration files and binaries are done only if they are
placed in the root filesystem.
You can use either the cmcheckconf –v or cmcheckconf –P commands to initiate the cluster
verification.
Run the cmcheckconf –v command to perform cluster wide verification of resources. This
command also verifies the packages that are presently deployed in the system. Run the
cmcheckconf -v 2 command to display the ERROR, WARNING, or INFO messages during
the package verification.
