Problem in starting Online

When i tried to up Online (oninit) I am getting this message oninit: cannot open chunk '/dev/rdsk/c0t6d0se' see online message log oninit: fatal error in shared memory initialization In Online.log (Message log file) it has been logged as 00:35:55 warning: chunk timestamps are invalid 00:35:55 I/O error, Primary Chunk '/dev/rdsk/c0t6d0se' -- Offline (sanity) 00:35:55 INFORMIX-OnLine Stopped Root dbspace size is 40000 Physical Log size is 1500 There are 6 logical log files with size as 600 Dynamic server version 6.x What could be the reasons? My problem is that I did'nt have any backup at all. Is that possible I can restore all my data. I need you suggestions on this. Please help us in restoring the data.

Even if it may be a bit expensive, call Informix Tech Support. Most of the time they are able to make Your server continue work. I wouldn't try to solve a problem like this on my own, because it's to risky.

This looks like a Solaris/Sun system. Is this a recently created engine instance? Did you remember not to use the first few cylinders for Informix chunks? If not you have probably over written the vtoc (Solaris partition table) stored there. Run prtvtoc /dev/rdsk/c0t6d0se and if you do not see a valid partition table you are hosed! BTW it is really bad practice to use the actual device file paths for chunks. It is much better, for many reasons, to create a directory containing symbolic links to the actual devices and use these link names' paths for chunk paths. Art S.
