The following topics in this chapter describe how to install and configure the Oracle Procedural Gateway for APPC:
Configuring an online transaction processor to allow access by the gateway requires actions on the OLTP and on certain components of the host operating system. Although no Oracle software is installed on the host system, access to, and some knowledge of the host system and the OLTP are required. Although this chapter includes some information about host system and OLTP installation steps, you must ensure that you have the applicable OLTP and host system documentation available.
Some of the configuration actions on the OLTP might require you to restart the OLTP. In preparation for this, have your host system programmer or DBA review the instructions for your OLTP to allow for any necessary preparations.
To install and configure the gateway with a single Oracle Integrating Server and a single OLTP, perform the procedures described in this chapter.
|
Note: If your gateway uses the SNA communication protocol, you will follow the instructions for installation and configuration in this chapter and in Chapter 5, " Configuring Your Oracle Network " and in Chapter 9, " Gateway Configuration Using SNA Communication Protocol ".If your gateway uses the TCP/IP communication protocol, you follow the instructions for installation and configuration in this chapter and in Chapter 5, " Configuring Your Oracle Network " and in Chapter 10, " Gateway Configuration Using TCP/IP Communication Protocol". |
If you have an earlier version of the Oracle Procedural Gateway for APPC installed on your system, you may be upgrading or migrating to the current release. A gateway "upgrade" represents a minor software upgrade within a release, (for example, moving from Release 9.0 to Release 9.2.0); a gateway "migration" represents a significant change from one version number to another, (for example, migrating from Release 9.0 to 10.1).
This section is only for customers who have a previous release of Oracle Procedural Gateway for APPC. If you have a previous gateway installation, you will need to carry out specific tasks before you can install Release 10.1.0.2.0 of the Oracle Procedural Gateway for APPC.
After reading this section, you will need to read Chapter 12, " Migration From Existing Gateways" to determine the specific actions you must take to prepare for upgrade or migration of your gateway. If you are migrating to Oracle Procedural Gateway for APPC Release 10.1.0.2.0 from version 4.01 or earlier, you will find specific material related to migration of the gateway in Chapter 12, " Migration From Existing Gateways".
You may find it helpful to refer to Appendix D, " Summary of Changes in Previous Versions" for information on changes or corrected problems from earlier releases of the gateway.
If you are installing for the first time, begin with "Performing Pre-Installation Procedures".
Perform the following steps to prepare for upgrading the Oracle Procedural Gateway for APPC to current versions:
Make backups of altered PGA shipped files.
Remove or rename any old gateway directories.
Upgrade considerations are as follows:
PGAU control files from Gateway Release 8 or 9 are upward compatible and you do not need to change them.
After upgrade, the PG DD contains all of its earlier entries without modification. New PGAU control information has been added along with some columns to support new features, but no customer entries are altered by the upgrade.
All TIPs from Oracle Procedural Gateway for APPC Release 4.0.1 or earlier must be recompiled, due to changes in the following:
PL/SQL compatibility
gateway server RPC interface
UTL_PG interface
TCP/IP only: If you have existing TIPs that were generated previously on a gateway using the SNA communication protocol and you want to utilize the new TCP/IP feature, then the TIPs will have to be regenerated by PGAU with mandatory NLS_LANGUAGE and Side Profile Settings. Specify the appropriate ASCII character set in the DEFINE TRANSACTION command.
This is due to the fact that the gateway assumes that the appropriate user exit in IMS Connect is being used, which would translate between the appropriate ASCII and EBCDIC character sets.
Before you install the gateway, perform the following pre-installation procedures:
Ensure that your system meets all of the hardware and software requirements specified in Chapter 3, " System Requirements".
A CD-ROM drive is required.
The Oracle Procedural Gateway for APPC is currently shipped on CD-ROM media. The hardware required for the medium on which the gateway was ordered must be installed on your system.
Ensure that your security requirements are met.
Refer to Chapter 3, " System Requirements" for more information about the security requirements for connections and data access on your OLTP.
Fill out the worksheet identifying unique parameter names needed to configure your system and your chosen communication protocol (either SNA or TCP/IP), which is located in Chapter E, " Configuration Worksheet".
Decide on a SID (system identifier) for your gateway. This SID is used in Section 9.7, "Configuring the Gateway".
The SID must be unique and must not be used by any other gateway or Oracle Integrating Server on the system.
SNA only: Your SNA package must be installed and configured before you can proceed with installation of the gateway. Ensure that your system can communicate with the OLTP using the SNA Server appropriate for your platform. Refer to Chapter 6, " Configuring the SNA Communication Package on Windows" for more information about setting up and configuring SNA for Windows.
TCP/IP only: Your TCP/IP package must be installed and configured before you can proceed with installation of the gateway. Refer to Chapter 7, " Configuring the TCP/IP Communications Package for IMS Connect" for more information about setting up and configuring TCP/IP for Windows.
Ensure that your system can communicate with the OLTP using the TCP/IP communication package for your platform.
If you need general information about installing Oracle products and using the Oracle Universal Installer, then refer to the Oracle Database Installation Guide.
You can install the gateway in either of the following ways:
On the same machine as the existing Oracle Integrating Server but in a different directory.
All tasks for this type of installation or upgrade are discussed in this section.
On a system different from a local Oracle Integrating Server.
On the same machine as the Oracle Integrating Server, and in the same Oracle home directory. Note that in this case, the Oracle Integrating Server and the gateway must be at the same release level.
For general information about installing Oracle products and how to use the Oracle Universal Installer, refer to the Oracle Database Installation Guide for Microsoft Windows and perform all necessary tasks there first.
If your server release is different than your gateway release, do not install the gateway in the same Oracle home directory as the Oracle Integrating Server. This is required to isolate the gateway from the Oracle Integrating Server upgrades that might cause incompatibilities if the gateway executables were relinked with later versions of the Oracle server libraries.
If you wish to install the gateway in the same Oracle home as the Oracle Integrating Server, then the release number of both products must be the same.
Logon to your Windows system as a member of the Administrators group. If you are not currently a DBA user, then contact your system administrator to create a DBA login user ID. Refer to the Oracle Database Installation Guide for login information.
If you are installing the gateway for the first time, ensure that there is enough space on the disk where the gateway will reside, as specified in"Disk Space Requirements".
Before beginning the gateway installation process, you must stop all Oracle services that are currently running. Follow these steps:
Click Start, then Settings, then Control Panel.
Choose Services. A list of all Windows services appears.
Select an Oracle service (those services begin with "Oracle").
Click Stop.
Continue to select and stop Oracle services until all active Oracle services are stopped.
Verify that the drive is assigned to the logical drive you selected and that you can access files on the CD-ROM.
|
Note: The installation steps that follow assume that the CD-ROM drive is mapped to the D: drive. |
