Check your message log (online.log) for status messages that pertain to bringing Dynamic Server 10.0 online. The conversion process ends when the following message is written to online.log:
Conversion completed successfully
This message indicates that the conversion process completed successfully, but it does not guarantee that each individual database was converted successfully. The message log could contain additional information regarding the success or failure of each individual database conversion. If a particular database conversion fails, then you should try to connect to the database to find out the exact cause of the failure.
At the end of the conversion of each individual database, the conversion process runs a script to update some system catalog table entries. The message log includes messages related to this script. The success or failure of the script does not prevent the usage of a database. If the script fails for a database, however, for better performance run the following script as user informix while connected to the database for converting to Dynamic Server 10.0 from Dynamic Server 7.3x or 7.24:
$INFORMIXDIR/etc/dummyupds7x.sql
If you encounter a failure during the conversion, you should revert to the source database server and then restore it from a backup.
The conversion process involves two phases: internal conversion and external conversion. Internal conversion is the process of converting each individual database in the system. External conversion is the process of converting the utilities, such as ON–Bar.
