System Requirements

This chapter describes the system requirements of Oracle Procedural Gateway for APPC. It contains the following sections:

Hardware Requirements

The hardware requirements for this release of the gateway are described in the following sections.

Processor

Table 3-1 lists the processor requirements for Oracle Procedural Gateway for APPC for your platform.

Table 3-1 Processor Requirements

Platform	Processor
AIX-Based Systems	IBM RS/6000
HP-UX	HP 9000 Series HP-UX that can run the required version of HP-UX
Solaris	A Sun SPARC workstation that can run the required version of Solaris

Memory

For most installations, Oracle Corporation recommends 256 of real memory to support Oracle Procedural Gateway for APPC.

The following factors affect the memory requirements of the gateway server process:

number of concurrent APPC connections open by each user
number of data items being transferred between the gateway and the remote transaction program
additional factors such as configured network buffer size
the Oracle Net protocol adapters that were included during the gateway installation

Network Attachment

Oracle Procedural Gateway for APPC requires any network attachment supported by the SNA Communication Package for your platform.

CD-ROM Drive

A CD-ROM drive is required for installation of the software.

HP-UX Only

Oracle uses ISO 9660 format CD-ROM disks with RockRidge extensions.

Disk Space

Table 3-2 lists the disk space requirements for the Oracle Procedural Gateway for APPC for your platform.

Table 3-2 Disk Space Requirements

Platform	Disk Space
AIX-Based Systems	1500 MB
HP-UX	800 MB
Solaris	500 MB

Software Requirements

The system software configuration described in these requirements is supported by Oracle Corporation provided that the underlying system software products are supported by their respective vendors. Verify the latest support status with your system software vendors.

Software Requirements for AIX-Based Systems

Depending on your platformm, the software requirements are as follows:

Table 3-3 lists the software requirements for AIX-Based Systems
Table 3-4 lists the software requirements for HP-UX
Table 3-5 lists the software requirements for Solaris

Table 3-6 lists the software requirements which are common across the UNIX platforms.

Table 3-3 Software Requirements for AIX-Based Systems

Item	Requirement
Operating System	AIX version 4.3.3 or AIX 5L
Communications	SNA Server for AIX version 6.01 or higher

The following table lists the software requirements specific to HP-UX.

Table 3-4 Software Requirements for HP-UX

Item	Requirement
Operating System	HP-UX version 11.0 is required on a 64-bit system.
Communications	HP-UX SNAPlus2 Link Release 11.x and HP-UX SNAPlus2 API Release 11.x or higher are required.

The following table lists the software requirements specific to Solaris.

Table 3-5 Software Requirements for Solaris

Item	Requirement
Operating System	Sun Solaris version 2.6 or higher.
Communication	Sunlink SNA Peer-to-Peer Communication Server version 9 SNAP-IX version 6

The following table lists the software requirements which are common across the UNIX platforms.

Table 3-6 Software Requirements Common Across UNIX Platforms

Item	Requirement
Oracle Integrating Server	The latest patchset for Oracle9i release 1 (9.0.1), Oracle9i release 2 (9.2.0), and Oracle8i release 8.1.7. If necessary, refer to your vendor for the latest patchset information.
OLTP	The OLTP must support mapped APPC conversations. If the OLTP transaction programs to be executed through the gateway perform database updates, then the APPC verbs CONFIRM, CONFIRMED, and SEND_ERR must be supported by the OLTP. These verbs implement APPC sync level 1. All resources controlled by an OLTP that can be updated by transaction programs invoked through the gateway must be defined as recoverable resources to the OLTP and host system if COMMIT/ROLLBACK capability is required for those resources. For example, a VSAM file updated by a CICS transaction must be defined to CICS as a recoverable file for COMMIT/ROLLBACK to control the updates. CICS/MVS and CICS/ESA Release 4.3 or higher is required CICS/VSE Release 2.3 or higher is required. IDMS-DC Release 12 or higher is required. IMS/TM Release 5.1 or later is required. APPC/MVS OS/390 V2R7 is required. Important: For a list of known restrictions, be sure to read the "Known Restrictions" section before proceeding with installation of the gateway.
Oracle networking products	Oracle Net Client and Oracle Adapter must be installed on the system where the Oracle9i Server is installed. In addition, Oracle Net and the Oracle Adapter must be installed on the system where the gateway is installed.

Item

Requirement

Oracle Integrating Server

The latest patchset for Oracle9i release 1 (9.0.1), Oracle9i release 2 (9.2.0), and Oracle8i release 8.1.7.

If necessary, refer to your vendor for the latest patchset information.

OLTP

The OLTP must support mapped APPC conversations. If the OLTP transaction programs to be executed through the gateway perform database updates, then the APPC verbs CONFIRM, CONFIRMED, and SEND_ERR must be supported by the OLTP. These verbs implement APPC sync level 1.

All resources controlled by an OLTP that can be updated by transaction programs invoked through the gateway must be defined as recoverable resources to the OLTP and host system if COMMIT/ROLLBACK capability is required for those resources. For example, a VSAM file updated by a CICS transaction must be defined to CICS as a recoverable file for COMMIT/ROLLBACK to control the updates.

CICS/MVS and CICS/ESA

Release 4.3 or higher is required

CICS/VSE

Release 2.3 or higher is required.

IDMS-DC

Release 12 or higher is required.

IMS/TM

Release 5.1 or later is required.

APPC/MVS

OS/390 V2R7 is required.

Important: For a list of known restrictions, be sure to read the "Known Restrictions" section before proceeding with installation of the gateway.

Oracle networking products

Oracle Net Client and Oracle Adapter must be installed on the system where the Oracle9i Server is installed. In addition, Oracle Net and the Oracle Adapter must be installed on the system where the gateway is installed.

Documentation Requirements

Oracle recommends that you read the following documentation on products other than the gateway:

PL/SQL User's Guide and Reference
Oracle9i Installation Guide for UNIX
Oracle9i Administrator's Reference
Oracle9i Server Concepts
Oracle9i Server Messages
Oracle Net Administrator's Guide
Programmer's Guide to the Oracle Call Interface

For Operating System and SNA communications package references, refer to the appropriate vendor documentation.
