2.1 Hardware Requirements

Table 2-1 shows the hardware requirements for Oracle Transparent Gateway for Sybase.

Table 2-1 Hardware requirements for Oracle Transparent Gateway for Sybase

Hardware Items	Required for AIX-Based Systems	Required for HP 9000 Series hp_ux	Required for Solaris Operating System	Required for hp Tru64 UNIX
CPU	IBM RS/6000 AIX-Based System Processor	HP 9000 Series 700 or 800 processor for hp-ux 11.0	Sun Solaris Operating System (SPARC) Processor	Alpha processor
Temporary Disk Space	500 MB	500 MB	500 MB	500 MB
Disk Space	1.5 GB	1.5 GB	750 MB	1.5 GB
Memory	512 MB	512 MB	512 MB	512 MB
Swap Space	1 GB	1 GB	1 GB	1 GB

2.1.1 Checking the Hardware Requirements

The system must meet the following minimum hardware requirements:

512 MB of physical RAM
1 GB of swap space (or twice the size of RAM)

On systems with 2 GB or more of RAM, the swap space can be between one and two times the size of RAM. On AIX systems with 1 GB or more of memory, do not increase the swap space more than 2 GB. See the Oracle Database Administrator's Reference for UNIX for more information about configuring swap space on AIX.
500 MB of disk space in the /tmp directory
Between 750 MB and 1.5 GB of disk space for the Oracle software, depending on the installation type and platform

To ensure that the system meets these requirements, follow these steps:

To determine the physical RAM size, enter one of the following commands:

Operating System	Command
AIX	# `/usr/sbin/lsattr -E -l sys0 -a realmem`
hp-ux	# `/usr/sbin/dmesg \| grep "Physical:"`
Solaris	# `usr/sbin/prtconf \| grep "Memory size"`
Tru64 UNIX	# `/bin/vmstat -P \| grep "Total Physical Memory"`

If the size of the physical RAM installed in the system is less than the required size, you must install more memory before continuing.

To determine the size of the configured swap space, enter one of the following commands:

Operating System Command

AIX # /usr/sbin/lsps -a

hp-ux # /usr/sbin/swapinfo -a

Solaris # /usr/sbin/swap -s

Tru64 UNIX # /sbin/swapon -s

If necessary, see your operating system documentation for information about how to configure additional swap space.

Operating System	Command
AIX	`# /usr/sbin/lsps -a`
hp-ux	`# /usr/sbin/swapinfo -a`
Solaris	`# /usr/sbin/swap -s`
Tru64 UNIX	`# /sbin/swapon -s`

2.2 Software Requirements

The follow section describes the software requirements for Oracle Transparent Gateway for Sybase.

2.2.1 Operating System

Table 2-2 shows the operating system version required for Oracle Transparent Gateway for Sybase.

Table 2-2 Operating Systems version for Oracle Transparent Gateway for Sybase

Operating System	Version
Solaris	Solaris 8 or Solaris 9, 64-bit
hp-ux	hp-ux 11i (11.11) PA-RISC
AIX	AIX 5L version 5.2, Maintenance level 1 or higher
hp Tru64 UNIX	hp Tru64 5.1b

2.2.2 Checking the Software Requirements

To ensure that the system meets the software requirements, follow these steps:

To determine which version of AIX is installed, enter the following command:
```
# oslevel -r
```
If the operating system version is lower than AIX 5.2.0.0 Maintenance Level 1 (5200-01), upgrade your operating system to this level. AIX 5L version 5.2 maintenance packages are available from the following Web site:

http://techsupport.services.ibm.com/server/aix.fdc

To determine which version of hp-ux is installed, enter the following command:

# uname -a
HP-UX hostname B.11.11 U 9000/800 109444686 unlimited-user license

To determine which version of Solaris Operating System is installed, enter the following command:
```
# uname -r
```
If your operating system is lower than Solaris 8 (5.8), upgrade your operating system to this level.
To determine which version of Tru64 UNIX is installed, enter the following command:
```
# /usr/sbin/sizer -v
Compaq Tru64 UNIX V5.1B (Rev. 2650); Mon Nov 3 10:13:28 PST 200
```
In this example, the version shown is V5.1B. If necessary, see your operating system documentation for information about upgrading the operating system.

2.2.3 Non-Oracle System Requirements

This release of the gateway supports Sybase Adaptive Server. For the latest versions supported refer to the OTN Web site:

2.3 Installation Steps for Oracle Transparent Gateway for Sybase

To install the gateway, follow these steps:

Run the Oracle Universal Installer

See "Running the Oracle Universal Installer" section for more information on running the Oracle Universal Installer.
Step through the Oracle Universal Installer

Oracle Universal Installer is a menu-driven utility that guides you through the installation of the gateway by prompting you with action items. The action items and the sequence in which they appear depend on your platform.

See Table 2-3 for description of the installation procedure of Oracle Transparent Gateway for Sybase.
Configure the Gateway

Refer to Oracle Transparent Gateway for Sybase Administrator's Guide of your platform for instruction on how to configure your gateway.

Step Through the Oracle Universal Installer

Table 2-3 describes the installation procedure for Oracle Transparent Gateway for Sybase.
