This chapter describes the system requirements of the gateway. It contains the following sections:
The hardware requirements for this release of the gateway on your platform are described in the following sections:
Table 3-1 lists the minimum hardware requirements for Oracle Database Gateway fro APPC.

The following factors affect the virtual memory requirements of the gateway server process:
Number of concurrent gateway connections open by each user
Number of data items being transferred between the gateway and the remote transaction program
The Oracle Net protocol adapters that were included during the gateway installation
Additional factors, such as configured network buffer size
The gateway requires any network attachment supported by either the SNA communication package for your platform or the TCP/IP Networking Facility for TCP/IP communication.
However, if you are using only the new TCP/IP support for IMS Connect feature, you will not need an SNA package. Your operating system comes with TCP/IP installed.
The system software configuration described in this section is supported by Oracle, provided that the underlying system software products are supported by their respective vendors. Verify the latest support status with your system software vendors.
This section contains the following topics:
Refer to the Oracle Database Installation Guide and to the certification matrix on My Oracle Support for the most up-to-date list of certified operating system version requirements to operate the gateway for your Linux 64-bit systems, AIX-Based, or Solaris system. The My Oracle Support Web site is available at
Each operating system uses specific communications servers, as described in this section.
Note:
If you choose to use TCP/IP support for IMS Connect as communication protocol, then you do not need to use an SNA communication package from the following list. Each operating system comes with a TCP/IP protocol automatically installed. If you choose to use the TCP/IP protocol, then you need to configure it to work properly with the gateway. Refer to Chapter 11, "Gateway Configuration Using TCP/IP Communication Protocol".Communications Protocols for Linux for Intel Pentium-based 32-bit Systems
Communications protocols for Linux for Intel Pentium-based 32-bit System IBM Communications Server V6.0.1.1 for Linux or higher, or the TCP/IP communication software that comes with your operating system.
Communications Protocols for AIX-based Systems
SNA Server for AIX version 6.01 or higher, or the TCP/IP communications software that comes with your operating system.
Communications Protocols for Solaris
SNAP-IX version 6 or higher, or the TCP/IP communications software that comes with your operating system.
All UNIX platforms require that the Oracle database, that is to act as the Oracle database be up to date with the latest patchset for supported Oracle database releases.
Oracle Net is automatically installed on the system where Oracle database is installed and on the system where the gateway is installed. Refer to Chapter 5, "Configuring Your Oracle Network" in this guide for detailed configuration information. Additionally, you might refer to the Oracle Database Net Services Administrator's Guide.
In addition to the other software requirements of the gateway and the platform being used, the following list outlines other requirements necessary on the IBM mainframe:
OLTP for SNA
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 SYNCLEVEL 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.
The gateway is compatible with all supported releases of SNA-enabled products such as CICS, IMS/TM, IDMS and z/OS.
Note:
For a list of known restrictions, read the "Known Restrictions" section before proceeding with the installation of the gateway.IMS/TM: Release 7.1 or later is required, as well as any APARs (patches) listed in the IBM IMS Connect Guide and Reference.
