Default Parameters for IBMDb2WorkloadTest

At configured intervals, this test compares the usage levels and execution times of all queries that started running on the server in the last measurement period and identifies a ‘top query’ in each of the following categories - CPU usage, memory usage, disk activity, and execution time. The test then reports the resource usage and execution time of the top queries and promptly alerts administrators if any query consumes more resources or takes more time to execute than it should. In such a scenario, administrators can use the detailed diagnosis of this test to view the inefficient queries and proceed to optimize them to enhance server performance.

This page depicts the default parameters that need to be configured for the IBMDb2WorkloadTest.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the USER text box, specify the name of the user who has any of the following privileges to the specified DATABASE: SYSADM or SYSCTRL or SYSMAINT or SYSMON. You can create a separate user on the OS hosting the DB2 server for this purpose, and assign any of the aforesaid privileges to that user. The steps for the same are detailed in the Creating a Special User for Monitoring DB2.

• Enter the password of the specified USER in the PASSWORD text box.

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

• Specify the name of the database on the monitored DB2 server to be used by this test, in the DATABASE text box.

• The test emulates a user executing a query on the specified DATABASE, and thus determines the availability and responsiveness of the database server. In the QUERY text box, specify the select query to execute.

• 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.
