the reason i'm asking this question is that i found (by dropping error logs) my DB size decreases substantially.  

they're not needed immediately, but i'd like to save them (for now) and if possible reload into the database.   is this even possible?

I have answered this part for ur previous question...
You can set the option how soon you can recycle it, by default it is unlimited. In order to recycle it , right click on the SQLServerLog from EM, and set the option there

yes, my question evolved a bit (and i noticed your response came in just after i accepted the last question - thanks for the last bit).  

but i started a new question... here's my problem:

1) DB size is out of control.  i'm performing many things including archival of unnecessary data.
2) When i delete the error logs it clears a lot of space
3) These error logs may be needed for viewing later... I'd like to analyze them when I have more time
4) However right now I want them *out* of the DB, to free space.

Is this possible?   Is it possible to detach an error log, archive it (as files only), then re-attach it later & use sp_readerrorlog to read it?   that would help me out.

you can change the path of the default path, i got this from another newsgroup

In Enterprise Manager, right click the server and choose
Properties. Click on the startup parameters button and
add a new one. For example to move it to c:\errorlog
you would add a new parameter

-ec:\errorlog\ERRORLOG


Then remove the old -e parameter (be careful it's the right one!)
Stop and restart the SQL Service and it's done.


You can backup up your previous settings before doing this by
exporting the following registry key (default instance)


HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSQLServer\MSSQLServer\Parameters
