Must be a DBSA to run this program - error

All, I've got a mysterious one for you. Last night, I tried to bounce one of our Informix engines so that I could make a change to the sqlhosts file. When I ran onmode -ky, I got the error, "Must be a DBSA to run this program." The error message had no error number. I was logged in as informix directly (i.e. not su'd from some other username), and I've confirmed that $INFORMIXDIR/bin/onmode has informix as its owner and group. The permissions on that file are -rwsr-sr-x. Has anyone seen this error before? I've performed an electronic search of Informix's Administration Guide and Error Messages manuals, and neither make any mention of this error message. I was concerned that the execute permission flag was set to "s" instead of "x", but it's also that way on our other servers, and they allow me to run onmode just fine. When I try to go through onmonitor to take the engine off-line, it goes through all the motions, and appears to work fine, but when you look at it, the engine is still on-line. I'm concerned that if I can't bring this system off-line through onmode, I might not be able to bring it on-line with oninit. Does this look familiar to anyone? Thanks for any insights. -- Kind regards, John Bejarano bebe stores, inc. Personal e-mail: jbejaran@yahoo.com
