Creating DDL to define a DB2 table
CICS PA builds the JCL that contains the CREATE TABLE statement required to define the DB2® table for this HDB data set. The HDB name is used as the table name, however you can change this by editing the JCL.
DSNTIAD, the sample Dynamic SQL program, is used to run the DDL that defines the DB2 table. CICS PA only provides a basic facility to load data into DB2. It does not provide any management or reporting capabilities once the data is in DB2.
- Create Options
- Select Create Database if you want the CREATE TABLE statement
to be preceded by a CREATE DATABASE statement to define the DB2 database. You might need to
ask your DB2 administrator to
do this for you if you do not have sufficient authority.
Select Create Storage Group if you want the CREATE TABLE statement to be preceded by a CREATE STOGROUP statement to define the DB2 Storage Group.
- Include Clock Field Components
- CMF performance class Clock fields accumulate data for both their count and time components in
the HDB. You have a choice as to which components to load into DB2. For example, selecting Time only will load the time component but not the count
component. Time only is sufficient for most analysis requirements.
For an HDB that is intended to be used in the CICS® PA plug-in for CICS Explorer®, this option must be set to "1. Time and Count".
- Summary Options
- Specify Include Sums of Squares to load sum-of-square values into the DB2 Table. CICS PA always loads the Total. This allows
you to calculate averages. Sums of Squares are required to calculate standard deviation and peak
percentiles. Totals (and not Sums of Squares) is sufficient for most analysis requirements.
This option must not be selected for an HDB that is intended to be used in the CICS PA plug-in.
Upgrade Settings
For details of the data set options you can specify when upgrading existing DB2 tables, see "Data Set Allocation Settings" in Define a Performance HDB.


When you have specified the options, press Enter to
generate the JCL and display it in an ISPF Edit session.
Review the JCL and make any changes you require. When the JCL is complete, submit it to create the DB2 table.
Review the job output in SDSF to verify that the table was created successfully.
