Very Very slow restore with SMO

Hello

I own a AIX 5.3 TL9 with Java 1.4.2, Oracle version 11g,  Smo 3.2 and SnapDrive 4.2,

I can say that the backups are done well, but we have made a FULL test Oracle Restore Control Files and now takes about 6 hours.

Anyone know what might be going to go so slow restoration.

thanks

Hi,

Basically, I've been on the same problem since yesterday. IHAC encountering the same problem.

The root cause seems to be with mount options. Data files are mounted with option "cio". When the SnapShot is connected (with this option) the copy is very slow (sequential access are slower).

I don't have any idea how get around it.

Regards,

Mathias

hello mrobicho

Indeed mount points were with the "CIO", we proceeded to change the file "filesystems", dismount and mount the mount points

Nowtherestorehas improved,the transfer rateis 1.5minutes the 1 GB of data.

We have won twice as long. !!

We have seen that done a lot of paging and do not know if there is any way to improve paging.

thanks
