Setting "Overwrite mode for the Log Area SAPDB"

Hello!

After Installing SAP Solution Manager and executing SGEN-jobs my DB-partition was full.

So I had to redirect the other Data files and log files to the other partition.

My free space on the second partition seems also to be full.

Now I am about to switch the log mode from "normal" to "Overwrite mode for the Log Area SAPDB".

What I should I do/prepare/check before executing this step?

(should SAP and/or DB be down)

After this:

Can I delete the existing Log files that are empty?

How can I check, which Log files are empty?

Thank you very much indeed!

regards

Thom
