WebSphere Enterprise Service Bus for z/OS, Version 6.2.0 Operating Systems: z/OS


Planning for product data sets

WebSphere® ESB for z/OS® product code resides in partitioned data sets (which contain the product data sets) and hierarchical file system directories (which contain the product directory and its subdirectories). The default high-level qualifier for the product data sets is BSB.

Product data set contents

The WebSphere ESB product data sets are divided into target data sets (used during product customization and execution) and distribution data sets (used to "back off" maintenance if necessary). In the following information, wesb_hlq is used to represent the high-level data set name qualifier for a particular set of WebSphere ESB for z/OS product data sets.

WebSphere ESB has the following target data sets:
wesb_hlq.SBSBEXEC
REXX execution scripts
wesb_hlq.SBSBJCL
JCL for installation jobs
WebSphere ESB has the following distribution data sets:
wesb_hlq.ABSBANT
installation file system files (ASCII)
wesb_hlq.ABSBEBCD
installation file system files (EBCDIC)
wesb_hlq.ABSBEXEC
REXX executables
wesb_hlq.ABSBJCL
JCL for installation jobs

See the WebSphere ESB for z/OS Program Directory (GI13-0527-00) for allocation information about each target data set and distribution data set. Updates to this information are included in the Preventive Service Planning (PSP) bucket for each release of WebSphere ESB for z/OS. You can find the Preventive Service Planning (PSP) bucket at http://www14.software.ibm.com/webapp/set2/psp/srchBroker.

Product data set naming convention

Certain WebSphere ESB for z/OS data sets must have the same high-level data set name qualifier in order for the product to function correctly. Product maintenance and migration is easier if all product data sets have the same high-level qualifier.

Alternatively, to continue to run WebSphere ESB for z/OS while applying maintenance, you must have at least two copies of the product data sets: one for the running application execution environment and one to which service is applied.

Choose a middle level qualifier for each separate release and maintenance level of WebSphere ESB for z/OS. This middle level qualifier can reflect a very simple production or test distinction; for example "BSB.V6PROD.*" or "BSB.V6TEST.*". Alternatively, the middle-level qualifier can include specific service level information; for example "WESB.W6610FP1.*" or "WESB.W610FP2.*".

There are many places where you must specify the product data set names, so, to avoid confusion, use the simplest data set naming scheme that accomplishes your maintenance goals.
