This part of the Natural CICS Interface documentation describes the customization of VSAM RRDS roll files.
It covers the following topics:
This section does not apply if you are using the Natural Roll Server.
Where appropriate, any references to CICS tables (DCT, FCT, PCT, PPT, TCT, etc.) can be considered as references to the corresponding:
assembly-type resource definitions,
online resource definitions via CEDA,
batch resource definitions via DFHCSDUP.
This Dokument covers the following topics:
Up to nine VSAM RRDS roll files can be allocated. Each roll file has an
ID consisting of a user-defined prefix followed by a fixed suffix. The prefix
can be 1 to 9 characters long. The suffix consists of two characters from
R1 to R9.
To add a new VSAM roll file, perform the following steps:
Create an empty VSAM RRDS conforming to your local site standards.
Then initialize the data set using the batch program NCISCPRI,
which must have been assembled during the Natural installation.The
SPACE and RECORDSIZE attributes can differ between
different roll files, so you can modify them as required to find the best
values in your environment.
Create an FCT entry and change the CICS JCL accordingly, using the prefix/suffix for both.
The new roll file becomes available when the Natural CICS Interface is initialized again.
Perform the following steps:
Ensure that Natural is not active.
Either delete the FCT and JCL definitions or delete the file.
The number of roll files is adjusted when the Natural CICS Interface is initialized again.
Perform the following steps:
Execute the procedures described above for decreasing the number of roll files.
Execute the procedures for increasing the number of roll files.
