sp_cycle_errorlog is generally better to use than dbcc errorlog, correct?

and, what is the procedure when switching the log over like that?  is it possible to keep the old error log at that point (back it up or archive it)?   just wanted to know what people generally do, procedurally.

sp_cycle_errorlog will indeed call dbcc ErrorLog, so there is no difference at all

Every time SQL Server is started, the current error log is renamed to errorlog.1; errorlog.1 becomes errorlog.2, errorlog.2 becomes errorlog.3, and so on. sp_cycle_errorlog enables you to cycle the error log files without stopping and starting the server.

i'm away from EM at the moment & am just trying to understand this -- is it possible to view errorlog.2 & errorlog.3?    they're part of the database itself (and contribute to filesize), correct?    if it's not possible to view them now, can i replace errorlog.1 with errorlog.2 at a later time?  

that is, i'm trying to understand the procedure for archiving/viewing these logs.   i got the impression that you don't simply cycle the error log & then delete it - it's kept for a later date; just trying to confirm this.   thanks!

Use 'sp_readerrorlog' for this pupose

sp_readerrorlog 2  --will read the second log

In order to recycle it , right click on the SQLServerLog from EM, and set the option there
