Oracle TS Parameters Test
This test measures the number of tablespaces that are not locally managed. This test is disabled by default. To enable the test, go to the enable / disable tests page using the menu sequence : Agents -> Tests -> Enable/Disable, pick Oracle Database as the Component type, Performance as the Test type, choose this test from the disabled tests list, and click on the << button to move the test to the ENABLED TESTS list. Finally, click the Update button.
This test reports the count and details of ‘dictionary managed tablespaces’ only. Since Oracle 9i (and above) supports ‘Locally Managed Tablespaces alone, this test is applicable only up to Oracle 8i.
Target of the test : An Oracle server
Agent deploying the test : An internal agent
Outputs of the test : One set of results for every instance of an Oracle database.
Configurable parameters for the test
- TEST PERIOD - How often should the test be executed
- Host – The host for which the test is to be configured
- Port - The port on which the server is listening
User – 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 here.
Password – Password of the specified database user
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.
- Confirm password – Confirm the password by retyping it here.
- ISPASSIVE – If the value 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.
DETAILED DIAGNOSIS – To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.
The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:
- The eG manager license should allow the detailed diagnosis capability
- Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
