The DbLogQueueTest monitors the usage of the log queue, which is the main memory area that stores redo log entries from transactions. The default parameters associated with this test are as follows:

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

• In the HOST text box, the host name of the component for which the test is to be configured has to be specified.

• In the PORT text box, specify the port at which the specified HOST listens.

• The test connects to a database on MaxDB and extracts performance statistics from the system tables in the database. Therefore, provide the name of a database in the DATABASENAME text box.

• Since users with the SYSDBA privilege alone are allowed access to system tables, specify the name of such a user against USERNAME.

• The password that corresponds to the USERNAME will have to be specified in the PASSWORD text box.

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

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific components, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
