StarSQL for UNIX v6.50 Release Notes

December 2022

StarSQL Provides Fast, Reliable Access to DB2

StarSQL for UNIX is a powerful ODBC driver that enables applications running on a UNIX workstation to transparently access, send SQL queries to, and retrieve results from DB2 databases running on remote IBM mainframe, midrange, or Unix systems. It supports the merged ODBC 3.0/CLI specification.

The following topics are addressed in these Release Notes. Refer to the StarSQL for UNIX Quick Start Guide for detailed information about installing StarSQL for the first time, and refer to the StarSQL for UNIX User's Guide (ssqlunix.pdf) for detailed information about using the StarSQL for UNIX driver.

What's New in StarSQL 6.50

This release of the StarSQL for UNIX introduces the following new features and improvements:

Upgrade Considerations

This section describes issues of interest for users who are upgrading from a prior version of StarSQL for UNIX.

Detailed Upgrade Considerations

See the technical document Upgrade Considerations for StarSQL 6.1 & Later for detailed information when upgrading to StarSQL 6.1x & later from earlier versions of StarSQL, including data source changes, installation hints and information about deprecated features.

Rebinding Packages

After installing StarSQL 6.x, you should rebind StarSQL packages on the host system if you upgrading from a version of StarSQL prior to V6.27. We suggest that you use StarAdmin to do this; see the StarSQL technical document Binding StarSQL Packages Using StarAdmin for details. StarAdmin is available for Windows or Linux. If you are using any version of StarSQL prior to v6.19, upgrade those clients to StarSQL v6.19 or later or use a different package collection.

There is no need to bind SQL packages for Derby databases.

Character Substitution

To identify problems with character conversion, StarSQL detects if one or more characters cannot be converted between the host and client character sets and substitutes a question mark, ?, in place of the character(s).  A warning is generated when the substitution occurs, which may be problematic for certain applications that are not anticipating this warning.  To avoid character conversion warnings, either correct any character conversion issues or, if the character substitution is acceptable, set the CharacterSubstitution value to Silent in the StarSQL DSN.

Dynamic SQL for Catalog Queries

To improve performance when connected to DB2 for z/OS servers, StarSQL executes dynamic SQL statements for catalog queries.  This behavior differs from versions of StarSQL prior to v5.36, where static SQL located in the driver's host packages was used to perform all catalog queries.  In order for StarSQL to use dynamic SQL for catalog queries, users must be granted SELECT privileges to the catalog tables, such as SYSIBM.SYSTABLES, SYSIBM.SYSCOLUMNS, SYSIBM.SYSROUTINES, etc.  If you want the StarSQL driver to use static SQL for catalog functions, set the UseDynamicCatalogSQL parameter to No in the StarSQL DSN. Refer to the StarSQL technical document SQV00SQ051 - StarSQL User Requirements for Dynamic SQL Catalog Queries for details.

StarSQL 6.34 & later supports (and properly describes) TIMESTAMP columns with a scale between 0 and 12. We have chosen to expose DB2's default timestamp precision of 6 as a separate data type name in SQLGetTypeInfo(), named "TIMESTAMP(6)", the type name "TIMESTAMP" is now described as having variable scale from 0 to 12. Setting the data source option HideTsScale=YES will instruct StarSQL to revert to pre-6.34 behavior and hide the variable scale version of TIMESTAMP in SQLGetTypeInfo().

DRDA tracing
The trcviewer application has been removed from StarSQL for UNIX. Instead, use the Trace Viewer on Windows to examine DRDA traces created on UNIX; append a .sqd extension and transfer the trace using binary mode.


System Requirements

You can install and run StarSQL for UNIX on computers with the following operating systems.

Linux x86_64 (AMD64 or Intel EMT64)


Host Databases:

You can use the StarSQL driver to connect to any of the following host databases:

FixPak and PTF Notes

This section describes specific IBM issues and the FixPak and PTFs that may be necessary for StarSQL to function properly.

Refer to StarSQL for UNIX User's Guide (ssqlunix.pdf) for specific IBM issues and the FixPak and PTFs that may be necessary for StarSQL for UNIX to function properly.

In addition to those documented in the User's Guide, the following FixPaks should be installed:

IBM i (OS/400) PTFs

In general, it is a good idea to stay current with the PTF CUM and HIPER packages and the DB2 Group PTF, and to use the latest version of StarSQL. The following sections describe more specific issues for different versions of IBM i (OS/400); check to see that the PTFs listed below are either installed or superseded.

Installing and Using the StarSQL for UNIX Software

Documentation Errata

UTF-8 characters and SQLBindParameter() with SQL_C_CHAR

To ensure proper conversion when using SQLBindParameter() with SQL_C_CHAR to insert UTF-8 characters such as the Euro sign ('€'), add ICONV4UTF8=Y to your ODBC data source.

Suppress Warnings from stored procedures

After upgrading from an older version of StarSQL or an older version of DB2, you may encounter new warning messages when invoking stored procedures; for example:


If you have an existing application that expects the older behavior, you can suppress warnings from stored procedures by adding the following to the [Default] section of $STARDIR/etc/swoodbc.ini (Where STARDIR is the directory where StarSQL is installed):


Known Issues
