This appendix provides a summary of changes in previous versions of the Oracle Procedural Gateway for APPC.
This appendix contains the following sections:
The following sections list changes and enhancements that were made to previous releases of the gateway.
The following section lists changes and enhancements that were made to release 10.1.0.2.0 of the gateway:
TCP/IP Support for Connecting the Gateway to IMS Connect Release 1.2
This release of the gateway includes TCP/IP support for IMS Connect. IMS Connect is an IBM product which allows TCP/IP clients to trigger execution of IMS transactions. The gateway can use a TCP/IP communication protocol to access IMS Connect, which triggers processing of IMS transactions. There is no SNA involvement with this configuration. Related to this new feature of the gateway is the pg4tcpmap tool. This release of the gateway includes a new tool whose purpose is to map the information from your side profile name to TCP/IP and IMS Connect attributes. You may turn on a trace for this tool as well. For more information about the gateway mapping tool refer to Chapter 10, "Gateway Configuration Using TCP/IP Communication Protocol".
Tip:
refer to Oracle Procedural Gateway for APPC User's Guide for Microsoft Windows for more information about the gateway mapping tool.Improved Gateway Log File
The log file for the gateway remote application has been improved.
The following section lists changes and enhancements that were made to Release 9.2.0.1.0 of the gateway:
Oracle Call Interface: Because of changes to the Oracle Call Interface (OCI), Oracle Procedural Gateway for APPC internal codes for calling COMMIT or CONFIRM have changed. This does not affect user functions.
APPC log file: The Oracle Procedural Gateway for APPC log file has been improved and provides more information about transactions. For a sample of the new log file, refer to Chapter 6 of the Oracle Procedural Gateway for APPC User's Guide for Microsoft Windows, Release 9.2.0.1.0.
Password encryption utility for gateway initialization file: This release of the gateway includes a utility to support encryption of plain-text passwords in the gateway initialization file.
The following section lists changes and enhancements that were made to Release 9.0.1.1.0 of the gateway:
Release 9.0.1.1.0 of the Oracle Procedural Gateway for APPC requires an Oracle9i release 9.0.1.1.0 (Oracle 9i database server 9.0.1) or higher Oracle Integrating Server.
If you are installing Oracle Procedural Gateway for APPC release 9.0.1.1.0 on the system for the first time, the ORACLE_HOME directory is C:\orant, by default.
The following section lists changes and enhancements that were made to Release 9.0.1.0.1 of the gateway:
PGA_TRACE parameter no longer supported: With this release of Oracle Procedural Gateway for APPC, the PGA_TRACE parameter is no longer supported. If you are copying the initsid.ora file from an older version of the gateway, then you must remove this parameter.
FDS_CLASS_VERSION parameter added: You will need to add the FDS_CLASS_VERSION parameter to your startup shell script file (initsid.ora). A default value is specified in initsid.ora.
The following section lists changes and enhancements that were made to Release 8.0.6.0.0 of the gateway:
The Oracle Procedural Gateway for APPC does not support Oracle7 server or earlier.
Heterogeneous Services architecture
This release of Oracle Procedural Gateway for APPC uses the Oracle Heterogeneous Services component within the Oracle8 server. Heterogeneous Services is the building block for the next generation of Oracle Open Gateways.
Performance enhancements
Oracle Procedural Gateway for APPC contains several internal performance enhancements. This product has shown major improvements over the version 4 gateways, particularly in response time and CPU utilization for all relevant address spaces for a variety of workloads. The actual performance improvement at your site may vary, depending on your installation type and workload.
PL/SQL V3 compatibility
Before release 8, you had to set the PLSQL_V2_COMPATIBILITY parameter to TRUE to compile PGAU80-generated TIP specifications. This is no longer necessary.
Oracle server dependencies
This release of Oracle Procedural Gateway for APPC requires that the Oracle Integrating Server be an Oracle8 server Release 8.0.6.0.0 or later.
Gateway initialization parameters
In previous versions of the gateway, the initialization parameters were stored in files named initsid.gtwboot and initsid.ora, both found in the gateway instance directories. With version 8, most parameters that were in initsid.gtwboot have been moved to the initsid.ora file. The syntax of initsid.ora has been simplified.
When migrating from previous releases of the gateway, be aware of these differences.
tnsnames.ora: The service name definition (from the Oracle Integrating Server to the gateway) must contain an extra parameter, (HS=(DRIVER)).
In this release of the Oracle Procedural Gateway for APPC for Microsoft Windows, the following names have changed:
PGAU80.EXE (known as PGAU80) has been changed to PGAU.EXE (known as PGAU).
PG4APPC80.EXE (known as PG4APPC80) has been changed to PG4APPC.EXE (known as PG4APPC)
With this release of the Oracle Procedural Gateway for APPC for Microsoft Windows, the gateway no longer runs as a Windows service. The process-based gateway provides faster performance because it does not need a management utility. Instead, each Oracle Integrating Server user session that accesses a particular gateway creates an independent process on Windows that runs the gateway server and executes SNA functions.
GTWSRV.EXE is no longer included
As a result of the process-based gateway, the Oracle Procedural Gateway for APPC package no longer includes the GTWSRV.EXE management utility.
The process-based gateway removes the restriction of a four-character limit for the SID name. Refer to the Oracle Database Net Services Administrator's Guide for more information about character limits for SID names.
The GTWCONF.EXE process is no longer included in the Oracle Procedural Gateway for APPC for Windows, beginning with this release.
Microsoft SNA Server version 2 is no longer supported with this release of the Oracle Procedural Gateway for APPC for Microsoft Windows.
The following section lists changes and enhancements that were made to release 4.0.1.1.0 of the gateway:
Gateway components now based on Oracle7 Server release 7.3.3
The gateway components are now built using the Oracle7 server release 7.3.3 product libraries as a base. All product components shipped with the gateway, including SQL*Net, are now at the release 7.3.2 level.
Gateway supports Oracle8 Server release 8.0.3
The gateway now supports Oracle8 server release 8.0.3 as an integrating server.
UTL_PG now shipped with Oracle Server
The scripts for installing the UTL_PG PL/SQL package are now shipped with the Oracle7 or Oracle8 server and are no longer shipped with the gateway.
Gateway no longer supports Oracle7 Server release 7.1.6 and 7.2
The gateway no longer supports Oracle7 server release 7.1.6 and 7.2 as integrating servers.
User ID and password overrides now supported by gateway (Enh. No. 423300)
A new TIP override is now available to allow the user ID and password sent by the gateway to the OLTP to be specified by the user. For complete information about using this override, refer to "Overriding TIP Initializations" in Chapter 2 of the Oracle Procedural Gateway for APPC User's Guide.
New LENGTH IS clause supported by PGAU (Enh. No. 428783)
A new LENGTH IS clause in COBOL data definitions is now recognized by PGAU and allows the definition of variable-length character fields without using OCCURS DEPENDING ON. For complete information on using this clause, refer to "Format Conversion" in Appendix G of the Oracle Procedural Gateway for APPC User's Guide.
Date/time stamp in trace output
All trace and debug output from the gateway server now contains a date/time stamp in the beginning of each line.
Installer improvements: The installer prompts not relevant to the gateway have been eliminated to streamline the installation process.
