Saving copies of the current configuration files
Save copies of the configuration files that exist for each instance of your source database server. Keep the copies available in case you decide to use the files after migrating or you need to revert to the source database server.
Although you can use an old ONCONFIG configuration file with Informix® , you should use the new ONCONFIG file, or at least examine the file for new parameters.
Configuration files that you might have are listed in Configuration files to save from the source database server.
| UNIX™ or Linux™ | Windows™ |
|---|---|
| $INFORMIXDIR/etc/$ONCONFIG | %INFORMIXDIR%\etc\%ONCONFIG% |
| $INFORMIXDIR/etc/onconfig.std | %INFORMIXDIR%\etc\onconfig.std |
| $INFORMIXDIR/etc/oncfg* | %INFORMIXDIR%\etc\oncfg* |
| $INFORMIXDIR/etc/sm_versions | %INFORMIXDIR%\etc\sm_versions |
| $INFORMIXDIR/aaodir/adtcfg | %INFORMIXDIR%\aaodir\adtcfg.* |
| $INFORMIXDIR/dbssodir/adtmasks | %INFORMIXDIR%\dbssodir\adtmasks.* |
| $INFORMIXDIR/etc/sqlhosts or $INFORMIXSQLHOSTS | %INFORMIXDIR%\etc\sqlhosts or $INFORMIXSQLHOSTS |
| $INFORMIXDIR/etc/tctermcap | |
| $INFORMIXDIR/etc/termcap |
If you use ON-Bar to back up your source database server and the logical logs, you must also save a copy of any important storage manager files and the following file:
- UNIX™ or Linux™:
- $INFORMIXDIR/etc/ixbar.servernum
- Windows™:
- %INFORMIXDIR%\etc\ixbar.servernum
The Informix® Primary Storage Manager does not use the sm_versions file. If you plan to use the Informix® Primary Storage Manager, you do not need the sm_versions file. However, if you use the Spectrum Protect or a third-party storage manager, you do need the sm_versions file.
If you are using a different directory as INFORMIXDIR for the new database server, copy sm_versions to the new $INFORMIXDIR/etc, or copy sm_versions.std to sm_versions in the new directory, and then edit the sm_versions file with appropriate values before starting the migration.
