Sybase Deadlocks Test

This test monitors the locking activity on the Sybase server, and reports the number of deadlocks. For this test to work, the following configuration parameters need to be enabled on the server:

  • enable monitoring
  • deadlock pipe max messages
  • deadlock pipe active

Target of the test : A Sybase ASE server on which the MDA tables have been installed

Agent deploying the test : An internal agent

Outputs of the test : One set of results for every Sybase ASE server being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

Refers to the IP address of the Sybase ASE server.

Port

The port number at which the Sybase server listens to.

User

To enable this test to connect to the Sybase server and collect the required metrics, it is enough if you configure the test with the name of a Sybase user who has the “mon_role”. However, for best results, it is recommended that you configure all Sybase tests with the credentials of a Sybase user who has the “mon_role”, “sa_role’, and “sybase_ts_role”.

Password

The password corresponding to the above user

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.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Number of deadlocks

The number of deadlocks found in the Sybase Server.

Number

A deadlock may arise due to various situations including bad design of queries and deficient coding practices. A deadlock is a situation where both/all the lock requestors are in a mutual or a multi-way tie. Any deadlocks are detrimental to database application performance. The detailed diagnosis for this measure provides a listing of dead locks for each lock type.
