System Login Flow

Art Wiens — Tue, 12 Jun 2007 09:36:48 GMT

I'm having a bit of trouble understanding which command procedures get called/run when a user logs in. Reading System Manager's Essentials, it says:

"System checks whether SYS$LOGIN is defined.

If SYS$LOGIN is defined, the logical name is translated (in the case of DCL, to SYS$MANAGER:SYLOGIN.COM) and that procedure executes. If SYS$SYLOGIN is not defined, no system login is run."

But SYS$LOGIN does not translate to that, it translates to the user's home directory.

I do have SYS$SYLOGIN defined, but it translates to SYS$MANAGER:SYS$SYLOGIN.COM (custom I'm sure).

The trouble is, there also is a SYLOGIN.COM which would appear to run as well ... trying to figure out how it gets invoked.

Or does the above statement just have too many words (if you leave out the "in the case of DCL") .. if SYS$LOGIN is defined, then it executes SYS$MANAGER:SYLOGIN.COM ?

Obviously I'm missing something (again)!

Cheers,
Art

Hi Art

Sys$login is the logical name for a users login directory.

Sys$sylogin, if defined, is the logical name for the system-wide login procedure, which is normaly sys$manager:sylogin.com

If sys$sylogin is undefined, the system executes sys$manager:sylogin.com as well.

The protection of those files may also be important (W:RE)

hope that helps

Geni

It's a documentation error. And an old one.
