StarPipes for Windows v4.08 Release Notes

April 2020


StarPipes is StarQuest's gateway product for DRDA communications for use with StarSQL, StarSQL for Java, and other DRDA requesters. It provides central management for access to multiple DB2 hosts through a single Windows server, Secure Sockets Layer (SSL) support for secure communcations, and TCP/IP-to-SNA conversion. In addition, it can be used to centralize the licensing for StarQuest products such as StarSQL, and can be used for troubleshooting DRDA applications that run as a Windows service, such as StarQuest Data Replicator and Microsoft SQL Server Linked Server.

The following topics are addressed in these Release Notes. Refer to the Quick Start Guide for StarPipes for Windows for detailed information about installing StarPipes for Windows for the first time, and refer to the StarPipes Help file for detailed information about using the StarPipes for Windows software.

What's New in this Release

This release of the StarPipes for Windows introduces the following new features and improvements:

Refer to the StarPipes Help file for detailed information.

Upgrade Considerations

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

If you are upgrading from StarPipes for Windows NT v2.20 and earlier, you must first remove the old version by selecting "Uninstall
StarPipes for Windows NT" from the StarPipes for Windows NT Program Group.

If you are replacing a 32-bit version of StarPipes with the 64-bit version, you must remove the 32-bit version first.

Upgrading from any version of StarPipes earlier than 4.0 will remove your StarPipes configuration; you should make a note of the configuration before upgrading.

System Requirements

You can install and run the StarPipes for Windows on computers with the following operating systems:

We recommend installing the latest Windows updates. For Windows Server 2012R2 and windows 8.1, the  April 2014 update rollup for Windows RT 8.1, Windows 8.1, and Windows Server 2012 R2 (2919355) is required.

StarPipes for Windows requires Visual C++ 2015/2017/2019 runtimes. The StarPipes installer will install the Microsoft-supplied Microsoft Visual C++ Redistributable package if it is not already present on the system. The Microsoft Redistributable package will remain on the system if StarPipes is upgraded or uninstalled.

This information supercedes the system requirements documented in the Help file.


During installation, you will be prompted for your choice of SNA server (Microsoft Host Integration Server, IBM Communications Server, or none). If you wish to switch later, you will need to reinstall StarPipes for Windows.

StarPipes for Windows will work with either the client or server software of the SNA server; however, for best performance we recommend that StarPipes for Windows be installed on the same machine as the SNA server.

FixPak and PTF Notes

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


Installing and Using the StarPipes for Windows Software

Known Issues

Email Notification and SMTP Authentication

When SMTP authentication is not being used, you can supply any value for the From field. When using SMTP authentication, the From field should be a valid email address hosted by the SMTP server, although it does not need to match the userID being used for SMTP authentication. If you supply an invalid email address for the From field, a misleading error message is displayed ("550 <> No such user here", where is the recipient).
