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 10.2.0.1.0 of the gateway:
Users migrating to Release 10.2.0 from a previous release of the gateway will no longer use the pg4hoa1.sh bootstrap shell script when defining listener.ora. In earlier releases, the value used when defining listener.ora was pg4hoa1.sh. You will now use the pg4asrv program directly.
SunLink cannot support 64-bit architecture and is no longer regarded as a strategic product for the Solaris platform. Therefore, with this release of the Oracle Procedural Gateway for APPC, the SunLink P2P SNA protocol is no longer supported for the Solaris Operating System. Instead, you must use the SNAP-IX SNA communication product.
APPC API calls are not supported for an SNA Communication Server 6.0.1 running on AIX 5L.
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 execution 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 might turn on a trace for this tool as well. For more information about the gateway mapping tool, refer to Chapter 6 of the Oracle Procedural Gateway for APPC User's Guide and to Chapter 13, "Gateway Configuration Using TCP/IP Communication Protocol" in this guide.
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/CONFIRM have changed. This does not affect user functions.
APPC log file: The Oracle Procedural Gateway for APPC log file is 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 UNIX, 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.
AIX-only: password encryption utility for Resource Recovery Manager: This release of the gateway includes another utility to support encryption of plain text passwords, which is called LOG_PASS in the initialization file for local LU. For more information, refer to "AIX-Based Systems Only: Using the pg4rrmpwd Utility" on page 5-6 in Oracle Procedural Gateway for APPC Installation and Configuration Guide, Release 9.2.0.1.0.
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.
TRACE_LEVEL and LOG_DESTINATION parameters moved: With this release of Oracle Procedural Gateway for APPC, the TRACE_LEVEL and LOG_DESTINATION parameters were moved from the pg4hoa1.sh file to the initsid.ora file.
FDS_CLASS_VERSION parameter added: You need to add the FDS_CLASS_VERSION parameter to your startup shell script file (pg4hoa1.sh). A default value is specified in pg4hoa1.sh.
The following section lists changes and enhancements that were made to Releases 8.0.6.1.0 and 8.0.4.1.0 of the gateway:
Heterogeneous Services architecture
This release of Oracle Procedural Gateway for APPC utilizes 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 8.0.6.1.0, you had to use the PLSQL_V2_COMPATIBILITY =TRUE parameter to compile PGAU-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 Version 8.0.6.2.0 (Oracle database server release 8.0.6.2.0) 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.
In addition, Oracle Procedural Gateway for APPC's executable (pg4asrv) calls the gateway indirectly through a startup shell script sample file called pg4hoa1.sh. This startup shell script is also used for setting SNA environmental variables, such as APPCLU.
tnsnames.ora: The service name definition (from the Oracle Integrating Server to the gateway) must contain an extra parameter, (HS=).
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 7.3.2
The gateway components are now built using the Oracle7 server release 7.3.2 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 (online transaction processor) to be specified by the user. For complete information on 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.

The following section lists restrictions that were known to exist in previous releases of the gateway.
AIX-Based systems only: two-phase commit provides no automatic recovery with CICS/ESA: When an update transaction with CICS/ESA at LU6.2 Sync Level 2 fails, CICS always rolls back or commits the transaction (based on the INDOUBT parameter of the CICS transaction definition), making automatic recovery by the Oracle Integrating Server impossible.
The following problems in other products are known to affect the operation of products in this release:
UTL_PG Does Not Handle Numeric Data Values Between 0 and +1 (Bug No. 360427)
The UTL_PG.NUMBER_TO_RAW function erroneously issues messages ORA-08414 and ORA-08467 when converting an Oracle number between 0 and +1 into a COBOL numeric value. Contact Oracle Support Services to order the patch correcting this bug.
