SQL/MX 3.2.1 Installation and Upgrade Guide (H06.26+, J06.15+)

Errors are generated under the following circumstances:
• If you assign a wrong value for number
• If a normal user executes the command (Only a SUPER ID user can convert the MXCS metadata.)
Warnings are generated under the following circumstances:
• If a qualifying row from ENVIRONMENTVALUES has an inconsistent value, the row is skipped
and a warning is issued.
• If a qualifying row from ENVIRONMENTVALUES has an ambiguous value, the row is converted
according to the format specification and a warning is issued.
Installing SQL/MX Release 2.x
To install SQL/MX Release 2.x, complete the following steps:
1. Install SQL/MX Release 2.x. For more information on installing SQL/MX Release 2.x, see
“Installing SQL/MX” (page 14).
2. Perform the operations described in “Migrating applications after system fallback” (page 54).
Migrating applications after system fallback
The modules that were generated on SQL/MX Release 3.2.x are no longer compatible after a
system fallback to an earlier release. Therefore, all such modules must be recompiled after system
fallback.
An alternate method is to save a copy of the modules before system upgrade and then reinstate
that copy after fallback. This method is applicable for the following scenarios:
• If the database layout after the fallback is similar to the layout before the system upgrade.
• If the application executables are not pre-processed, language-compiled and linked on SQL/MX
Release 3.2.x.
NOTE: The application programs, which are pre-processed and language-compiled on SQL/MX
Release 3.x, are not compatible with SQL/MX Release 2.3.x. After a fallback to SQL/MX Release
2.3.x, such application programs must be pre-processed and language-compiled before recompiling
the modules.
Changes required after falling back
Falling back might require changes to some or all of these corequisite product versions, particularly
if you fall back to an earlier RVU:
• RDF (Independent Product)
• NonStop Server for Java
• JDBC Driver for SQL/MX
• DP2
• TMF
• Measure
• Backup and Restore 2
For more information, see the Release Version Update Compendium for H06.25, J06.14 or later
RVUs.
