Chapter 8 Configuring Your Pagestore on z/OS : Defining an Additional Segment

Defining an Additional Segment
Tasks Required to Define Additional Segments
You can define additional segments as your system requirements increase. To define an additional segment, complete the following tasks:
 
Task A Edit and save the sample JCL
1.
2.
3.
4.
Refer to TIBCO Object Service Broker for z/OS Installing and Operating for more information about this sample JCL.
5.
Sample JCL
The following sample JCL defines five segments. The first, segment 0, uses the installation supplied name. The second, segment 99, uses the installation supplied name. The next three page segments are named SALES, EXPENSES, and PURCHASE.

 
//ASM.SYSIN DD *
DBSET Q1=S6B
DB TYPE=PAGE,ACBS=3,NAME=SEGMENT0
DB TYPE=PAGE,ACBS=1,NAME=SEGMNT99,ID=99,SYSTEM=Y
DB TYPE=PAGE,ACBS=3,NAME=SALES,ID=01
DB TYPE=PAGE,ACBS=3,NAME=EXPENSES,ID=02
DB TYPE=PAGE,ACBS=3,NAME=PURCHASE,ID=03
DBSET Q1=S6B,NAME=OSB50
DB TYPE=JOURNAL,ACBS=2
DB TYPE=REDOLOG
DB TYPE=RESOURCE
DB TYPE=CACHE
DB TYPE=PENDING
DBGEN

 
Task B Define new data sets
Use IDCAMS to define the new data sets to be added to the segment. All z/OS naming conventions apply to the naming of the data set. The data set names must be:
Q1.NAME.PAGEn
Example
Following the sample JCL, the data set names for data in segment 1 would be:
S6B.SALES.PAGE1
S6B.SALES.PAGE2
S6B.SALES.PAGE3
Task C Format the data sets
After you define the new data sets, you must format them to prepare them for the data:
1.
Update the S6A5FRMT member in the OSB.INSTALL data to include new DD lines with calls to S6BTLFPS for the Q1.NAME.PAGEn data sets.
Ensure that you specify only the new data set names in your DD statements. S6BTLFPS fails if you try to initialize data sets that are not empty.
2.
Upon completion, the new data sets are initialized.
Task D Shut down the TIBCO Object Service Broker system
To ensure an orderly shutdown, complete the following steps:
1.
2.
3.
4.
5.

Task E Submit the S6A5DBDG for execution
When you submit the S6A5DBDG for execution it executes in the same manner as it did during the initial installation process. As part of the job, other routines are called that assemble and link edit the updated database information. Output is sent to the DBDLIB.
Task F Restart the Data Object Broker
From the system console, issue the command to start the Data Object Broker as shown in the following example:
/F OSTARDOB
