Running onsmsync in single-user mode
Precisely what does onsmsync do when it is run with no parameters, and in what order, i.e., what is it using as basis of comparison: storage manager, sysutils database or ixbar file? Will I lose data if someone mistakenly runs onsmsync without parameters? Also, the manual is somewhat equivocal on this point: Does onsmsync behave differently if it is run in single-user mode? Using IDS 10.00.FC6 on RHEL4/2.6.9

Thank you ever so much for your redundant response, but I need a useful answer from somebody who can reply knowledgeably.

Running onsmsync with no options synchronises the ixbar file and the sysutils database with what the storage manager knows. From the manual : no options Synchronizes the sysutils database and emergency boot file with the storage-manager catalog e.g. You can drop / create the sysutils database and remove the ixbar.<SERVERNUM> file, then running onsmsync the ixbar file and the sysutils database is populated from the storage manager information. You will not lose data if someone runs it "mistakenly" without any parameters. 2. Running in single user mode as informix and it runs fine - identical. 3. Review the BAR_ACT_LOG file for more details, and if even more details are required set BAR_DEBUG to various values from 1 to 9 (I would NOT recommend setting higher that 5 in a big instance). 10.00.FC6 is no longer in support.
