Today’s Business Challenges

We often hear…

“I used to manage DB2 for z/OS, now I have IMS too”

“We have four production systems, three test systems, multiple

LPARs…and I have to maintain all of it”

“The guy who wrote that has left, so we don’t touch it for fear it will break”

• Increased burden of IMS management and maintenance – systems are large and complex

• Unanticipated problems

• Downtime

• Loss of revenue

• Problem determination time and resource intensive

• Expert personnel

• Spend time on maintenance/administration

• Prefer to develop new applications, pursue new technologies, and grow business

Utility JCL Generation

• Generate task-based, error-free utility JCL

• Product/utility registration

• IBM IMS Tools ‘register’ themselves during setup

• Skeletons and variables

• IBM IMS Tools will provide base skeletons and variables

• Users can modify base skeletons or create their own

• Create User Profiles for all levels of expertise

• Object Profiles define Groups of Databases based on sets of rules

• Utility Profiles define Groups of IMS Tools Product Functions

• Job Profiles combine one Object Profile and one Utility Profile

• Many Job profiles can share Object and Utility profiles

41




Object Profiles – Choose and Group IMS objects

42




Object Profiles – Choose and Group IMS objects

Object profiles allow you to select and group your

IMS objects to perform certain functions on them.

You can filter down to select the object(s) you are

interested in and then set specific rules and options

to control how they are processed.

43




Utility Profiles – Customize the Utility Functions to Perform

44




Utility Profiles – Customize the Utility Functions to Perform

Choose from a long list of IMS functions and then generate

the JCL to drive them against your IMS objects. You can

select individual functions and then reorder them to define

customized sequences of job steps.

45




Combine Functions and Order Them

46




Combine Functions and Order Them

Update your Utility profile by

selecting individual functions and

reordering their sequence to

generate just the JCL job you

desire. You have total control and

you always have the opportunity

to edit your JCL later.

47




Job Profiles – Create and Save for Anyone to Run

48




Job Profiles – Create and Save for Anyone to Run

The real power comes when

you combine your Object

and Utility profiles to create

customized Job profiles.

49




DDNAME and Keyword Variables Automatically Populated
