Generalized sequential access method (GSAM) databases are
sequentially organized databases that are designed to be compatible
with z/OS® data sets. Use the
GSAM database PCB statement section of the PSB summary page to
create or alter a GSAM database PCB statement. The GSAM database PCB
statement defines a view that controls how application programs can
access the GSAM database.
Before you begin
Open the
PSB summary page for
the PSB that contains the GSAM database PCB.
Procedure
- From the GSAM database PCB statement section of the PSB
summary page, you can create a GSAM database PCB statement, and remove
and modify existing statements.
- To create a PCB statement, click Add.
A new row is added to the table and the statement properties you can
modify are displayed. A sequential PCB number uniquely identifies
the new row.
- To remove a PCB statement, click a row in the
table to select it, then click Remove.
- To edit a PCB statement, click a row in the table
to select it, then click Edit and modify the
properties. You can edit only one statement at a time.
You can specify values for these statement properties.Property |
