utility daemon

niniti

I have asked this question before also, but did not get satisfactory reply.

At what time does utild come in picturey. Its very briefly mentioen in manual that its used for impersonation for commands. I dont understand this much. WHen I preview an output and if there is an error in TPL, I have to check iwutild_cmdout.log.

SO please let me know at what operations does utility daemon come in picture and how ?

Thanks

Processes run as a single user, "NT Authority\SYSTEM" on Windows and "iwts"+"iwui" on Solaris and Linux. When those processes write to the filesystem, the changes would register as those users. In order to "act on the behalf" of the logged-in user, the process needs some OS-level magic to "pretend" the user is logged on to the OS and is the one doing the changes. The Utility Daemon is a process that contains OS-specific native code, allowing other IW processes to operate on behalf of other users by actually doing the operations and changing the operational user and group SIDs.

In short, if IW was acting alone, all your generated files would be modified by "SYSTEM". The utild makes it such that the files are modified by the user who triggered the generate call.
