IMAGE/SQL and TurboIMAGE/XL Overview
STATISTICS command of ISQL for each of the tables you access
frequently. If you have created SQL data using an earlier release of
IMAGE/SQL, perform the ALLBASE/SQL migration to migrate your
DBEnvironment to the current G3 format. For more information, refer
to the ALLBASE/SQL Database Administration Guide.
TurboIMAGE/XL is enhanced to increase the concurrency of
modification intrinsics, DBPUT, DBDELETE, and DBUPDATE (Critical Item
Update feature ON). To use this enhancement, your database must be
activated to use the Dependency Semaphore. To achieve this, the
ENABLE and DISABLE commands of DBUTIL introduce a new option,
DSEM. The default for DSEM is DISABLED.
Important Information
1. The default for Critical Item Update option is now changed from
DISALLOWED to ALLOWED.
2. A jumbo data set cannot be enabled for dynamic expansion.
3. If you have third-party indexing (TPI) enabled for the database and
want to create B-Tree indices, obtain the correct version of the
third-party software which recognizes this coexistence. Otherwise,
you will get run-time errors returned by third-party software for new
modes of DBFIND, DBINFO, and other utility commands.
ODBCLink/SE
IMAGE/SQL is bundled with ODBCLink/SE, which is a replacement for
HP PC API. ODBCLink/SE is an implementation of Microsoft's Open
Database Connectivity (ODBC) interface that enables Microsoft
Windows based applications and tools to access TurboIMAGE/XL data
on the HP 3000 in a client/server environment.
HP PC API will no longer be distributed with IMAGE/SQL software. It
can co-exist with ODBCLink/SE but will no longer be enhanced. For
more information, refer to the article, "Introducing ODBCLink/SE," in
this Communicator 3000 and the manual, ODBCLink/SE Reference
Manual, which is bundled with IMAGE/SQL.
