Hi all !
We have a strategic OLTP application which use an 8.1.7 database on Solaris 2.8.
This database is not in archivelog mode and the only backup performed on it is a simple daily export full (that's for real !).
There is no physical backup (copy of the datafiles).

I know that it would be very necessary to implement a secure backup strategy ...
But I'm just wondering if the archivelog mode will not cause slowdown performance problem ...

Does anybody could share his experience on the implementation of the archivelog mode and performance problem on Solaris with 8.1.7 databases ?

Thanks a lot in advance !
