Work Management Standards › Using Libraries › Naming Convention for Libraries › Library Types

Library Types

Live production libraries should be of type *PROD. Development libraries should be of type *TEST: they may then be safely used in conjunction with live data under debug if UPDPROD(*NO) is specified when using the OS/400 Start Debug (STRDBG) command.

The above convention gives the following benefits:

• Complete segregation of the live and test data
• A test environment that is as close to the live environment as possible
• Separate backup regimes for data, application objects, and source
• Control of implementation of changes, retention of the penultimate version, preservation of existing authorities
• Control of conflicts due to changes made off-site or on a parallel machine
• Different data test packs
• Eventual archiving of source
• Use of software tools to implement new versions

The following are examples of the library lists required to use the system described above.
