Default Parameters for OraRacSessWaitTest

The OraRacSessWaitTest connects to the global view on the monitored Oracle server in an RAC (Real Application Cluster), and pulls out critical statistics pertaining to the session-level cluster-related events that wait on the global cache or any other global resource on that Oracle server.

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

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

• In order to monitor an Oracle database server, 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.  

• The INFO text box, indicates the variable name of the oracle instance.

• In the EXCLUDE text box, provide a comma-separated list of wait events that need not be monitored. For example, your specification can be: gc cr request,gc buffer busy. By default, 'none' is displayed here indicating that all wait events are monitored, by default.

• 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.

• Once the necessary values have been provided, click the UPDATE button, which 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.
