Hi all

in the network\Admin directory my Oracle home directory
we have the listener ,sqlnet and tnsnames.ora files together with these we do have a lot of files with names like

listener98062411PM2545.bak
listener9807228AM0120.bak

tnsnames98060810AM2548.bak
tnsnames9806197AM3316.bak

sqlnet98062612AM3319.bak
sqlnet9807228AM0120.bak

Waht are these files? are these required for database operation ? can i delete then ?

Sorry to take your time ?

If you use an assistant to modify these files, existing files get copied to backup (.bak). You can manually edit the files, and there are pro's and con's about doing it.

Can you get rid of them? Yes. Should you? That's up to you.
