First check if in your Server Configuration document has notes.ini settings added.

Now go to the Domino server console and type in, "set conf LOG=log_New.nsf,1,0,7,15000", 15000 is the page length shown in log, 7 the number of days.

to check it go to the Domino server console and type in, "sh conf log*".

When the server restarts a new log will be made.

Note: The log can be deleted, or renamed when the domino server is offline and a new log is made automatically.

Mr. Scott,

I'm trying to change parameter LOG=log.nsf,1,0,9,50000 to LOG=log.nsf, 1,0,5,40000 ,2. Actually I'm trying reduce log.nsf file size, according to IBM's suggestion the link below:

Thank You !!!

Are you running the notes administrative client on the same machine as the dominio server?  Also, ensure that you have complete access (OS level Access to the notes.ini).

Open names.sf, view Configurations, check ALL Configuration documents, "notes.ini" tab if an admin has not put the log parameter there just in case....
