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.
OSS Name Server Limits Relief Migration Issue
The default values of the INODECACHE and LINKCACHE attributes of the OSS Name
Server are changed from 4096 to 64,000.
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 .
