Application Migration

After a system fallback, you must reformat RCBs for all database objects, before

accessing the database. Fallback SPR is provided for SQL/MX Release 2.3.4 (ANC

SPR on H06.21). To fall back to an earlier release of SQL/MX 2.x, you must adopt the

following sequence:

1. Fall back to SQL/MX Release 2.3.4.

2. Fall back to the required SQL/MX 2.x version.

Note. SQL/MX Release 2.3.x metadata (v 1200) for existing applications and data objects in

existing catalogs can co-exist on a single system with SQL/MX Release 3.0 metadata (v 3000)

for objects in newly created catalogs. To use version 3000 metadata for existing objects, all

existing version 1200 metadata must be upgraded and embedded applications recompiled.
