Tibero TSM Test

This test periodically monitors the space usage of the shared memory, and proactively alerts administrators to excessive space consumption by, or deficiencies in space allocations to, the shared memory.

Target of the test : A Tibero Database server

Agent deploying the test :An internal agent

Outputs of the test : One set of results for the target Tibero Database server being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The host for which the test is to be configured.

Port

The port to which the specified host listens. By default, the port number is 8629.

User and Password

In order to monitor a Tibero database server, a special database user account has to be created in every Tibero database instance that requires monitoring. A Click here hyperlink is available in the test configuration page, using which a new Tibero 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 any dictionary and create session privileges.

The sample script we recommend for user creation for eG monitoring is:

create user tibeg identified by tibeg default tablespace <users> temporary tablespace<temp>;

grant create session, select any dictionary tibeg;

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. This login information is required to query Tibero'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.

Tibero SID

Specify the SID of the target Tibero database instance that is to be monitored in this text box.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total size

Indicates the total size of the shared memory space.

MB

 

Used size

Indicates the used size of the shared memory space.

MB

 

Free size

Indicates the free size of the shared memory space.

MB

Ideally, the value of this measurement should be very high.

Space usage

Indicates the space usage of the shared memory space.

Percent

Typically, a low percentage of free space is desired. A value close to 100 or a consistent increase in the value of this measure could indicate excessive space consumption by the shared memory or insufficient space allocation; lack of free space for shared memory can severely affect database performance, and can even cause the database to hang! To avoid such adversities, you might want to consider allocating more space to the shared memory.
