Use the SQL Activity window to view subsystem-wide SQL
activity for determining the SQL workload on the system. This information
displays the number of times each SQL statement has been executed.
To display this window, select SQL Activity from
the DB2® Statistics Detail panel.
The SQL Activity window consists of the following sections:
Total DML (Data Manipulation Language)
This section shows the number of executions performed by various
SQL statements concerning the manipulation of data.
Total DCL (Data Control Language)
This section shows the number of executions performed by various
SQL statements concerning the controlling of various activities.
Total DDL (Data Definition Language)
This section shows a table that contain the number of executions
performed by various DDL SQL statements for each of the applicable
object types. These SQL statements are used to create, drop, and alter
objects.
Incremental Binds
This field is the number of INCREMENTAL BINDs.
If a plan is
bound with VALIDATE(RUN), Db2 performs
validity checks (such as authorizations and existence of referenced Db2 objects) at bind time and rechecks
any failures at run time. This can result in catalog contention and
degraded application performance, depending on the number of statements
flagged and the number of times they are executed. Therefore VALIDATE(RUN)
should be avoided as much as possible. Ensure that all objects are
created and all privileges are granted before binding, and select
the VALIDATE(BIND) option.
In addition to plans bound with
VALIDATE(RUN), this counter is incremented for plans using Db2 private protocol.
