You can use to
tune SQL statements that you are monitoring in Optim Performance Manager.
Before you begin
- The IBM Data Studio client must be installed on the system
where the browser that you are using for Optim™ Performance Manager is installed.
- The DB2® database
or subsystem that your SQL statements run against must be configured
for query tuning.
- The IBM Data Studio client must be running, and the
embedded HTTP server must be active. To check whether the embedded
HTTP server is active, move your cursor over the embedded HTTP server
button in the toolbar at the top of the IBM Data Studio client. Read
the tooltip that appears. If the server is not running, click the
button.
- If you are capturing SQL statements from the Optim Performance
Manager repository, the database or subsystem that the SQL statements
run against must be enabled for monitoring.
- If you are capturing SQL statements from the Optim Performance
Manager repository, ensure that your user ID is authorized to access
the performance metrics stored in the repository database. To be authorized,
your user ID must be a member of the user group that was authorized
for accessing the repository database. This authorization takes place
when InfoSphere Optim Performance Manager is installed.
