Urgent - loggin problem and logical log problem

Hello, i am familiar to Oracle but new to Informix. Since this morning some users cannot logged into the database some others can. I check this with dbaccess. dbaccess return the error message : ...err = -951.... A second problem since this morning : i can´t start „ontape –a“; the error message is : could not write log tape Is there an relationsship ? I shutdown the Informix Server and restart it. This dosn´t work. Thank´s in advance Rainer

So those users for who it is failing do not have a valid login on the server host that matches either their local login name or id or the username specified in the ~/.netrc file for the server host. > A second problem since this morning : > > i can´t start „ontape –a“; the error message is : > > could not write log tape > Is there an relationsship ? Nope different problem. Any other information like an errno? Can you read/write/position the tape manually using 'mt' or 'dd'? Is the LTAPEDEV parameter in the ONCONFIG file set to "/dev/null"? You cannot back up logs to /dev/null using ontape they are automatically discarded when LTAPEDEV = /dev/null so no backup is neccessary or possible. > I shutdown the Informix Server and restart it. This dosn´t work. I imagine it did not since the engine seems fine. Art S. Kagel
