Hi,

I have an issue with export(expdp).

When i exporting an user using expdp utility, the load the on the server is going up-to 5. The size of the database is 180GB. Below is the command that i use for export.

expdp sys/xxxx directory=dbpdump dumpfile=expdp_trk_backup.dmp logfile=expdp_trk_backup.log exclude=statistics schemas=trk

Can you please help me to resolve this issue!

Do i need any look into any memory parameters for this?

Thanks
Sivanarayana

If your server is a 10 CPU one, having a load of 5 just means your server is idle.
If your server is a 1 CPU one, this means it is overloaded on CPU.
How changing a memory parameter would change this?
Either increase the parallelism of expdp hoping they will wait on IO, or remove others activity.

Michel
