Default Parameters for OraDgTest

This test helps administrators determine whether the oracle Data Guard feature is enabled, and if enabled helps figure out the current role of the database server. The test also reveals whether any standby database has switched into production role recently.

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

• 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 (in Oracle database server versions before 12c) 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 sample script we recommend for user creation (in Oracle database server 12c) for eG monitoring is:

  alter session set container=<Oracle_service_name>;

  create user <user_name>identified by <user_password> container=current default tablespace <name_of_default_tablespace> temporary tablespace <name_of_temporary_tablespace>;

  Grant create session to <user_name>;

  Grant select_catalog_role to <user_name>;

  The name of this user has to be specified in the USERNAME text box.

• In the PASSWORD text box, specify the password of the specified database user.

• Confirm the password by retyping it in the CONFIRM PASSWORD text box.

• If the value of ISPASSIVE chosen is YES, then the Oracle server under consideration is a passive server in an Oracle cluster. No alerts will be generated if the server is not running. Measures will be reported as “Not applicable” by the agent if the server is not up.

• Once the necessary values have been provided, 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.
