Mapping

Output of this command is used to fill in the attributes of the CIs:

CMD Output Attribute	CI Name	CI Attribute
SomeClusterName	Service Guard Cluster	Name
PackageName1,..., PackageName3	SG Package	Name
IP Address	SG Resource	Name
Subnet value	Network	Name
Node1	Node	Name

Output:

/etc/cmcluster/scripts/exampleapplicatie.cfg
/etc/cmcluster/package1/package1.cfg
/etc/cmcluster/package2/package2.cfg
/etc/cmcluster/package3/package3.cfg

Mapping:

This command is used to find package configuration files in the SG Cluster configuration directory.

Output:

/etc/cmcluster/scripts/exampleapplicatie.config
/etc/cmcluster/package1/package1.config
/etc/cmcluster/package2/package2.config
/etc/cmcluster/package3/package3.config

Mapping:

This command is used to find package configuration files in the SG Cluster configuration directory.

Output:

# "PACKAGE_NAME" is the name that is used to identify the package.
# Legal values for PACKAGE_NAME:
PACKAGE_NAME package1
# "RUN_SCRIPT" is the script that starts a package.
# Legal values for RUN_SCRIPT:
RUN_SCRIPT /etc/cmcluster/package1/package1.cntl
# "RUN_SCRIPT_TIMEOUT" is the number of seconds allowed for the package to start.

Mapping:

PACKAGE_NAME and RUN_SCRIPT variable values are used in further commands for discovery of IP and Mount Points, which are managed by this package.

Output:

Jul 11 09:27:10 - Node "Node1":
Mounting /dev/vg1/lvol1 at /oracle/somename1
Jul 11 09:27:22 - Node "Node1":
Mounting /dev/vg1/lvol2 at /oracle/somename2
Jul 11 09:27:53 - Node "Node1":
Mounting /dev/vg1/lvol3 at /oracle/somename3

Mapping:

Discovered data for mount points will be used to link the RunningSoftware to the proper Clustered Service (actually a package). This linking approach relies on the running process path.

Output:

Jun 12 09:27:11 - Node "Node1":
Adding IP address 192.168.62.146 to subnet 192.168.62.0
Jun 12 09:27:11 - Node "Node1":
Adding IP address 172.24.10.142 to subnet 172.24.0.0

Mapping:

Discovered IP Address and Network will be reported as corresponding CIs. This is done because not all IP Resources might be present in the cmviewcl output.

Output:

orauser 21926 1 0 Jun 9 ?
6:09 /oracle/somename1/applic/oracle/db/
10.2.0/instns1/bin/tnslsnr listener_name1 -inherit

Mapping:

From the fetched Oracle Listener process information ORACLE_HOME value, listener name and pid will be parsed out. ORACLE_HOME and listener name will be used in further discovery to get listener status and parse out Oracle DB SIDs.

The command completed successfully

Mapping:

Instance value will be parsed out and treated as SID; any instance name starting from PLSExtProc will be filtered out since this is RPC call service.

Mapping:

Discovered IP and port information is used to set Application IP and Port on reported Running Software.

Mapping:

The Oracle iAS CI name is taken from value of ias-instance in the following order: parameter name, parameter id, Default Server.
