NonStop SQL/MP
Fallback
After falling back, you must install the previous SPRs for the OSS products and DP2.
In addition, in either of the following cases, you must run fsck on Version 3 filesets to
downgrade the filesets to Version 2:
•
If the fsck utility has been run on a fileset to upgrade it to a Version 3 fileset.
•
If the fileset was created on a system running the G06.29 or later RVU.
NonStop SQL/MP
After migrating to a new version of NonStop SQL/MP, falling back to a previous version
is more difficult if you have performed any of these actions:
•
Create a SQL/MP catalog whose version is newer than the previous version of the
SQL/MP software. This situation occurs automatically when you create a catalog
on a node running the new version of the software.
•
Create a SQL/MP table using new features that cause the version of the table to be
newer than the previous version of SQL/MP software.
•
Compile a program using the new version of the SQL/MP compiler.
In general, try to determine whether a fallback is necessary before performing these
actions.
NonStop SQL/MX Release 2.1.1
For more information about migrating to NonStop SQL/MX 2.0 and 2.1.1, see the
Interactive Upgrade Guide 2 and the SQL/MX Installation and Management Guide.
Requirements for migrating to NonStop SQL/MX 2.1.1 are similar to those for NonStop
SQL/MX 2.0. See also the SQL/MX Comparison Guide for SQL/MP Users and the
T0650 softdoc, which is the master softdoc for SQL/MX software components.
Note. NonStop SQL/MX Release 2.0 (released with the G06.27 RVU) and later requires
processors that support IEEE floating-point functions. All processors in a node on which
NonStop SQL/MX Release 2.0 or later is installed must be Model 1954 (S72000) or later. A
processor halt%005101 can result when one or more processors in a system do not meet the
minimum hardware requirements for installing NonStop SQL/MX Release 2.0.
In addition to supporting IEEE floating-point functions, a NonStop system on which NonStop
SQL/MX Release 2.0 or later is installed must support the SQL/MX minimum requirement of 1
GB per processor. Therefore, the S74000, S7000, and S7400 cannot be used because they do
not support the minimum memory requirement. For more information about the SQL/MX
hardware and memory requirements, see the SQL/MX Installation and Management Guide.
