Oracle Database File Status Test

This test reports the status of each datafile in each database of an Oracle instance and the current access mode of every datafile.

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.

Note:

This test will not report metrics for an Oracle 12c CDB server.

Target of the test : An Oracle server

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every datafile on the Oracle server.

Configurable parameters for the test
  1. TEST PERIOD - How often should the test be executed
  2. Host – The host for which the test is to be configured
  3. Port - The port on which the server is listening

  4. 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.

  5. 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.

  6. Confirm password – Confirm the password by retyping it here.
  7. 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.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

File status:

Indicates the current status of this datafile.

 

The table below indicates the values that this measure can report and their corresponding numeric equivalents:

Numeric Value Measure Value
1

System
2

Online
3

Recover
4

Unknown

If a datafile is part of the SYSTEM tablespace, its status is SYSTEM (unless it requires recovery).

If a datafile in a non-SYSTEM tablespace is online, its status is ONLINE. If a datafile in a non-SYSTEM tablespace is offline, its status can be either OFFLINE or RECOVER.

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the current status of a datafile. However, in the graph of this measure, data file states will be represented using the corresponding numeric equivalents only - i.e., 1 to 4.

File access mode:

Indicates the current access mode of this datafile.

 

The table below indicates the values that this measure can report and their corresponding numeric equivalents:

Numeric Value Measure Value
0

Disabled
1

Read Only
2

Read Write
3

Unknown

Note:

By default, this measure reports the above-mentioned Measure Values while indicating the mode through which this datafile can be accessed. However, the graph of this measure will be represented using the corresponding numeric equivalents i.e., 0 to 3.
