5.7 Upgrading from Tuxedo Previous Releases to Oracle Tuxedo 22c Release 1 (22.1.0.0.0)

If you are upgrading from Oracle Tuxedo previous releases to Oracle Tuxedo 22c Release 1 (22.1.0.0.0), please note the following:

• In order to allow an Oracle Tuxedo 22c Release 1 (22.1.0.0.0) server to interoperate with Tuxedo 6.5 software, the Oracle Tuxedo 22c Release 1 (22.1.0.0.0) server servopts -toption must be specified. The server may be a workstation listener (WSL) process (where the servopts -t option allows interoperability for all of its workstation handler—WSH—processes), a domain gateway (GWTDOMAIN) process, or a system or application server process. For more information, see GWTDOMAIN(5) in the Oracle Tuxedo File Formats, Data Descriptions, MIBs, And System Processes Reference.
• In order to allow a domain gateway (GWTDOMAIN) in Oracle Tuxedo 22c Release 1 (22.1.0.0.0) to interoperate with a domain gateway running on Tuxedo 6.5. you must upgrade to Tuxedo 6.5 patch level 446.

  If you have not upgraded to patch level 446, then you must set the TM_GWT_OLDSECCHECK environment variable of the domain gateway in this Oracle Tuxedo 22c Release 1 (22.1.0.0.0). For more Oracle Tuxedo environment variable information, see tuxenv(5) in the Oracle Tuxedo File Formats, Data Descriptions, MIBs, And System Processes Reference.

• If your Tuxedo 6.5 COBOL program calls TPINITIALIZE(), you must set the TM_CBL_IGNORE_CONTEXT environment variable to “Y” when you run the COBOL application. For more Oracle Tuxedo environment variable information, see tuxenv(5) in the Oracle Tuxedo File Formats, Data Descriptions, MIBs, And System Processes Reference.
• In this release, tpreturn() API method throws an exception when an error is encountered. You need to change your existing code to invoke tpreturn() API method in a try-catch block; otherwise, you fail to successfully compile the code.
