Hardware Requirements

Table 4-1 lists the minimum hardware requirements for Oracle Database Gateway for Informix.

Table 4-1 Hardware Requirements for Oracle Database Gateway for Informix

Hardware Items	Required for IBM AIX on POWER Systems (64-Bit)	Required for Linux x86 64 bit	Required for Oracle Solaris on SPARC (64-Bit)	Required for Oracle Solaris on x86-64 (64-Bit)	Required for HP-UX Itanium
Temporary Disk Space	400 MB	400 MB	400 MB	400 MB	400 MB
Disk Space	1.5 GB	750 MB	750 MB	750 MB	1.5 GB
Physical Memory*	512 MB	512 MB	512 MB	512 MB	512 MB
Swap Space	1 GB	1 GB	1 GB	1 GB	1 GB
Processor	IBM RS/6000 AIX-Based System Processor	x86_64	Sun Solaris Operating System (SPARC) Processor	x86_64	HP Itanium processor for hp-ux 11

* The minimum swap space is 1 GB (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.

Checking the Hardware Requirements

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

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

Operating System	Command
IBM AIX on POWER Systems (64-Bit)	# `/usr/sbin/lsattr -E -l sys0 -a realmem`
Linux x86 64 bit	`# grep MemTotal /proc/meminfo`
Oracle Solaris on SPARC (64-Bit)	# /`usr/sbin/prtconf \| grep "Memory size"`
Oracle Solaris on x86-64 (64-Bit)	# /`usr/sbin/prtconf \| grep "Memory size"`
HP-UX Itanium	`# /usr/contrib/bin/machinfo \| grep -i 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
IBM AIX on POWER Systems (64-Bit)	`# /usr/sbin/lsps -a`
Linux x86 64 bit	`# grep SwapTotal /proc/meminfo`
Oracle Solaris on SPARC (64-Bit)	`# /usr/sbin/swap -s`
Oracle Solaris on x86-64 (64-Bit)	`# /usr/sbin/swap -s`
HP-UX Itanium	`# /usr/sbin/swapinfo -a`

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

To determine the amount of disk space available in the /tmp directory enter the following commands:

Operating System	Command
IBM AIX on POWER Systems (64-Bit)	`# df -k /tmp`
Linux x86 64 bit	`# df -k /tmp`
Oracle Solaris on SPARC (64-Bit)	`# df -k /tmp`
Oracle Solaris on x86-64 (64-Bit)	`# df -k /tmp`
HP-UX Itanium	`# bdf /tmp`

To determine the amount of disk space available on the system enter the following commands:

Operating System	Command
IBM AIX on POWER Systems (64-Bit)	`# df -k`
Linux x86 64 bit	`# df -k`
Oracle Solaris on SPARC (64-Bit)	`# df -k`
Oracle Solaris on x86-64 (64-Bit)	`# df -k`
HP-UX Itanium	`# bdf`
