$SDEHOME/temp is full

[ArinStark]

I have many enterprise SDE connections that recently stopped working.  When I try to connect, I get a message reading "Failed to connect to database.  Temporary file I/O error -- possibly $SDEHOME/temp is full."  This is on my local desktop, not the SDE servers.   I am still able to connect to some SDEs.  

Details:  Am using ArcInfo 9.3.1.  The connections are all direct, but otherwise no consistent similarities.  Some are Oracle, some SQL Server; some are Windows-authenticated, others contain names/passwords.  The very few connections that still work are also varied.  And I seem to be the only user in the group having this problem.

Any ideas would be appreciated.

The SDEHOME for a Direct Connect connection is on the client (usually the ArcGIS install directory).
Check for permission issues on any "temp" directories in your install.

Thanks for the suggestion.  I expanded permissions on any "Temp" directory I could find.  There is no "SDEHOME" environment variable set on my local machine.  Still having the problem.

I've never heard of this problem before, so it's probably pretty rare.  You'll probably
need to work with Tech Support, but first try a re-install of ArcGIS Desktop.

Unfortunately, a complete re-install from scratch didn't fix the problem either.  But I do appreciate your time and suggestions.

I had this same problem. I had changed my $TEMP system variable to C:\temp from the default location. When I changed it back to the stupid Microsoft location my SDE connection worked fine.

Talk about chasing your tail for no benefit.

At least I didn't re-install...

I got this error, add full control for all user on $SDEHOME and I got the same error.

Then I check if the user that run the service that start the program using arcobjects code, then I see that the user who has the permission to run this service was deleted.

Then I change for an user that exist and had permission and works fine.

Soooo... as usually the message error could betray you.

When trying to connect to a database in ArcCatalog or ArcMap, a user gets this error: "Failed to connect to database. Temporary file I/O error -- possibly $SDEHOME/temp is full"

This is due to the temp folder being full

Solution:

Set the Windows Environmental Variables to "c:\temp" then logged out and logged back in and the connection was successful (see screenshot)
