This test reports the numerical statistics of the wait events pertaining to all the session modules of this Oracle instance.

This page depicts the default parameters that need to be configured for the OraRacSesModuleTest.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed. 

• Specify the variable name of the oracle instance in the ORASID text box.

• In order to monitor an Oracle Cluster, a special database user account has to be created in every Oracle database instance that requires monitoring. A Click here hyperlink is available in the test configuration page, using which a new oracle database user can be created. Alternatively, you can manually create the special database user. When doing so, ensure that this user is vested with the select_catalog_role and create session privileges. The sample script we recommend for user creation for eG monitoring is:
  
  create user oraeg identified by oraeg
  create role oratest;
  grant create session to oratest;
  grant select_catalog_role to oratest;
  grant oratest to oraeg;

  The name of this user has to be specified in the USER text box, and the password of this user has to be entered in the PASSWORD text box. Confirm the password by retyping it in the CONFIRM PASSWORD text box. This login information is required to query Oracle's internal dynamic views, so as to fetch the current status / health of the various database components. 

• If the ISPASSIVE parameter is set to YES, then it means that, by default, all Oracle servers being monitored by the eG system are the passive servers of an Oracle cluster. No alerts will be generated if the servers are not running. Measures will be reported as "Not applicable" by the agent if the servers are not up.

• A ServiceName exists for the entire Oracle RAC system. When clients connect to an Oracle cluster using the ServiceName, then the cluster routes the request to any available database instance in the cluster. By default, the SERVICE NAME is set to none. In this case, the test connects to the cluster using the ORASID and pulls out the metrics from that database instance which corresponds to that ORASID. If a valid SERVICE NAME is specified instead, then, the test will connect to the cluster using that SERVICE NAME, and will be able to pull out metrics from any available database instance in the cluster.

  To know the ServiceName of a cluster, execute the following query on any node in the target cluster:

  select name, value from v$parameter where name = ‘service_names’

• Once the necessary values have been entered, clicking on the Update button will register the changes made.

When changing default configurations of tests, the values with "$" indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to "xyz" and $port will be changed to "80" when configuring a test.
