Shared memory. Error.

Posted in 2003

Summary

A user reported two issues starting IDS 2000: the online log complained that chunk '/home/informix/dbs/tempdbs' must have owner-ID informix and group-ID root, even though the symlink itself appeared correctly owned, and running onstat as user informix failed with "Shared memory: permission denied" while it worked as root. The only reply asked what the underlying permissions were on the symlink's target device, /dev/raw/raw10 (the usual suspect, since the link's own ownership is irrelevant). No further posts appear, so no resolution is recorded in the thread.

Hi, - When starting informix the following error appears: 12:52:14 Informix Dynamic Server 2000 Initialized -- Shared MemoryInitialized. 12:52:14 Physical Recovery Started. 12:52:14 The chunk '/home/informix/dbs/tempdbs' must have owner-ID"informix" a nd group-ID "root". 12:52:14 Physical Recovery Complete: 0 Pages Restored. 12:52:14 Logical Recovery Started. the file tempdbs has the correct permissions: 0 lrwxrwxrwx 1 informix informix 14 mar 13 2003 tempdbs -> /dev/raw/raw10 - When I execute the command "onstat" with the user informix, the following error appears: onstat: Shared memory: permission denied. when it's the root that executes it, it works perfectly ! ??? Thanks in advance.
