A subset of the installation steps are required
to upgrade an existing version 1.2 system to version 2.1.
You must complete three actions to upgrade
CICS®
VT
system components:
- my.SVIDCNFG.custom member VIDB2BND
binds the version 2.1
DB2®
packages and plans. Refer to
Bind CICS VT packages and plans
for instructions.
The package VIDMIGG2 is new in version 2.1.
All
CICS VT
system DBRMs have a version ID related to the product version. If you
have to fallback from version 2.1
to version 1.2, you do not have to run version 1.2
my.SVIDCNFG.custom
member VIDB2BND.
When you have fully migrated to version 2.1, the version 1.2 packages
can be freed. The version ID
for version 1.2 is CVT120.
- The existing version 1.2
CICS VT
objects defined in
CICS are used by
version 2.1. New
CICS VT
objects associated with the VTMU transaction must be to be defined to
CICS.
Member VIDCDEF2 in my.SVIDCNFG.custom
contains the input to the batch CSD update
utility to define the new objects. Add them to the same
CICS
group as the existing version 1.2 objects. The default group name is VID.
- There are 5 new JCL procedures in version 2.1. The version 1.2
procedure VIDPRE is
replaced by procedure VIDDB2 in version 2.1. Refer to
Make JES JCL procedures available
for a discussion on implementing JCL procedures.
