3 System Requirements

3.1.1 CPU

The gateway requires any processor that can run the required z/OS operating systems listed in "Software Requirements". 

3.1.2 Disk Space

The following are the disk space requirements:

• Temp z/fs: 600 MB.

  If you want to further reduce the requirement of temporary z/fs disk space, then delete the zip file after uncompressing it, and before running the installer. After running the Oracle installer, if you are sure you would not need to configure another gateway instance, then you can delete the installer home which is the result of uncompressing the zip file.

• Permanent z/fs: 220 MB with locale builder, 166 MB without locale builder

• Permanent Data Set Space: 200 cylinders

3.1.3 Virtual Memory

Each concurrent user of the gateway increases the virtual memory consumption, and it varies depending on:

• The number and complexity of SQL statements referring to tables through the gateway

• The number of columns and column sizes of those tables

• The configured network buffer size

• The number of open cursors and the HS_RPC_FETCH_SIZE initialization parameter

Oracle recommends defining 0M for the REGION parameter in the Oracle Transparent Gateway for DB2 address space.

Oracle also recommends defining 0M for the REGION parameter in the Oracle Net address space.

3.2.1 Operating System

z/OS 1.4 (or V1R4) or higher is required.

3.2.2 UNIX System Services (USS)

An operational z/OS UNIX System Services (USS) is required.

3.2.3 IBM Maintenance

Oracle recommends running Oracle Transparent Gateway for DB2 at the most current operating system service level.

3.2.4 DB2 Maintenance

If you are using the current version of the Oracle Transparent Gateway for DB2 to access DB2 v7.1 you need to apply the following DB2 maintenance:

APAR PK20664: SQLCODE330 ON DESCRIBE OF A PREPARED STATEMENT USING BIND OPTION ENCODING(UNICODE). The corresponding PTF is UK13641.

3.4.1 Oracle Net IBM TCP/IP

A z/OS host using Oracle Net IBM TCP/IP requires hardware capable of interfacing with the IBM TCP/IP stack.

The IBM TCP/IP software must be on the same z/OS system as Oracle Net IBM TCP/IP.
