Re: Bus error

I will try to help you.
I do not have idea about Oracle bbdd, so if you want if there was a I/O problem, then you have to see the /var/adm/syslog/syslog.log file or using dmesg command.
I hope this help you.

I would like to be lie on a beautiful beach spending my life doing nothing, so someboby has to make this job.

Re: Bus error

Thanks Juanma but it is not I/O problem. Host works fine, DB works fine.

Please read Bill Hassell's response:,,0x68cca2db8513d6118ff40090279cd0f9,00.html

On solaris the error "kgefec: fatal error 0" is caused by this:

EXPORT of DB on different platform leaks memory in the Export process. This memory leak can cause the export to fail with errors of the form: "kgefec: fatal error 0"

Re: Bus error

We ran into this today.. and found this article on metalink.. we did as it said and it worked fine...

Cause ~~~~~~~ The operating system was not able to keep up with the Oracle Process. Fix ~~~~ Check system logs for errors. There may be an issue with physical memory. Try decreasing the buffer size in the export to prevent Oracle from sending so much data at once. In some environments, increasing the buffer will allow Oracle to hold more data in the buffer before sending it to the OS allowing the OS to catch up. Try running the export with DIRECT = TRUE. This will bypass the heap and heap and all possibility of this issue. If you are running the export from a client and the database is not the same wordsize, ie one is 32bit and the other is 64bit, you could be experiencing bug#2298968(unpublish), One-off is available for and in Metalink, fixed in, and
