Change Man is a comprehensive system designed toprovide both reliable & streamlined implementation of

software changes from development into production.

Change Man lets you quickly

implement an automated inf rastructure

that delivers tangible and long-term

benefits.

What is ChangeMan ?

Create Change Package Within Change Man, a Change Package is the vehicle in which all

changes are moved from a development environment to a production

environment.

A change package may contain one or more components (source,

copybook, load, JCL, control cards, compiling procedures,

documentation, and other components) which are required to

implement a software change.

Checkout The checkout process allows to copy components from baseline

libraries to a Change Man staging library or to a personal

development library where you can make changes.

Components such as fixes,Control cards or copy members are

copied into the staging libraries, if they are not there already.

For source components, staging will run the appropriate

translation procedures to create associated load modules.

16/33

The audit process identifies out-of-synch condition with in the BaselineLibraries and other participating packages.

It Checks whether package is complete and logically correct

MUST RUN Prior to Freeze

Out-of-synch conditions could result from:

Copybooks being modified after compiling the source component thatcalls them

A package containing a load component that does not match its sourcecomponent

Member Not being active

Member Copied, but not staged

Promotion allows a package to be moved through

various levels of testing. For example, promote from system testing to

acceptance testing.

The freeze process locks the package and makes the package

available for the promotion and approval processes.

Approve


25/33

The approval process consists of browsing the package information and

Staging Libraries for quality control and standards and selecting to

Approve (or Reject) the package.

A change package must be in Frozen (FRZ) status to be Approved or

Rejected.

After all of the approvals have been gathered by Change Man, the

package is ready to be installed.

Installation depends on whether or not an internal scheduler is set up

If no scheduling system is specified, the package goes through the

Installation process immediately.

If a Scheduling system is specified , the package follows the respective

Scheduling system.

BackoutPromote


30/33

If there is a problem with the change package after it has been Installed,

the change package is backed out by deleting the updated component in

production and then retrieving the previous version of application

software from the Backup Library.

ChangeMan will back out the entire package by copying the components

from the Backup Libraries to overlay production.

The package status is changed from BAS to BAK.
