For Linux
To display the timeout value, enter:

Checking for hardware errors
The following types of hardware error messages indicate problems that may
lead to database corruption:
• Disk read, write, or retry errors
• Timeouts
• System panics
• Memory problems of any type
For HP-UX
Check the /var/adm/syslog/syslog.log file on a regular basis. You can view the
file directly, or you can use the HP-UX
dmesg
command. See your operating
system documentation for more information.
