Adaptive Server checks the file version number when each instance is started. The version number in the server configuration file must match the version number that is stored on the quorum device. If the file version numbers do not match, Adaptive Server prints an error message, extracts the latest copy of the configuration file from the quorum disk to the local file system, and aborts the instance start-up.
At this point, you can decide whether to restart the instance using the latest configuration file, or you can manually edit the file and then restart the instance.
If the version numbers now match, and there has been no change to the configuration file, you can successfully restart the instance.
If you edit the configuration file, the version numbers match, but the content of the configuration file has now changed. Restart the instance: Adaptive Server automatically increments the version number, updates the sysconfigures table with the new version number, writes the new configuration file to the local directory and to the quorum device, and instructs all instances to dump a new copy of the configuration file from the quorum device.
