TnsAdmin
|
string-scalar |
The $TNS_ADMIN path to directory in which the Listener configuration file resides (listener.ora).
Default is /var/opt/oracle.
|
|
Listener
|
string-scalar |
Name of Listener. The name for Listener is considered case-insensitive by the Netlsnr agent and the Oracle database server.
Default is LISTENER.
|
|
LsnrPwd
|
string-scalar |
The ApplicationHA encrypted password used to stop and monitor the listener. This password is set in the Listener configuration file.
Encrypt passwords only when entering them using the command-line. Passwords must be encrypted using the ApplicationHA Encrypt utility.
|
|
EnvFile
|
string-scalar |
Specifies the full path name of the file that is sourced by the entry point scripts. This file contains the environment variables set by the user for the Oracle listener environment such as LD_LIBRARY_PATH and so on.
The syntax for the contents of the file depends on the login shell of Owner. This file must readable by Owner. The file must not contain any prompts for user input.
|
|
MonScript
|
string-scalar |
Pathname to the script provided for detail monitoring. By default, the detail monitoring is enabled to monitor the listener process.
Note: |
If the value of the attribute MonScript is set to an empty string, the agent disables detail monitoring. |
The pathname to the supplied detail monitoring script is /opt/VRTSagents/ha/bin/Netlsnr/LsnrTest.pl.
MonScript also accepts a pathname relative to /opt/VRTSagents/ha. A relative pathname should start with "./", as in the path ./bin/Netlsnr/LsnrTest.pl.

IMF
|
integer-association |
This resource-type level attribute determines whether the Netlsnr agent must
perform intelligent resource monitoring. You can also override the value of
this attribute at resource-level.
This attribute includes the following keys:
-
Mode: Define this attribute to enable or disable intelligent resource
monitoring.
Valid values are as follows:
0 - Does not perform intelligent resource monitoring 1 - Performs intelligent resource monitoring for offline resources and
performs poll-based monitoring for online resources 2 - Performs intelligent resource monitoring for online resources and
performs poll-based monitoring for offline resources 3 - Performs intelligent resource monitoring for both online and for
offline resources Default: 3
-
MonitorFreq: This key value specifies the frequency at which the agent
invokes the monitor agent function. The value of this key is an integer.
Default: 5
You can set this key to a non-zero value for cases where the agent
requires to perform both poll-based and intelligent resource monitoring.
If the value is 0, the agent does not perform poll-based process check
monitoring.
After the resource registers with the AMF kernel driver, the agent calls
the monitor agent function as follows:
-
RegisterRetryLimit: If you enable intelligent resource monitoring, the
agent invokes the netlsnr_imf_register agent function to register the
resource with the AMF kernel driver. The value of the RegisterRetryLimit
key determines the number of times the agent must retry registration for
a resource. If the agent cannot register the resource within the limit that
is specified, then intelligent monitoring is disabled until the resource state
changes or the value of the Mode key changes.
Default: 3
|
|
Encoding
|
string-scalar |
Specifies operating system encoding that corresponds to Oracle encoding for the displayed Oracle output.
Default is "".
|
|
IntentionalOffline
|
static-boolean |
