New configuration option allows you to disable IFIL path improvements so files can be opened by earlier releases
FairCom DB includes enhancements to the storing of data and index file paths in the IFIL resource of a c-tree data file to avoid potential problems when files are moved to a different location. An attempt to open a data file that was created with these enhancements with a V11.5 (or earlier) server fails with error FREL_ERR (744, "file requires unavailable feature").
FairCom Server supports a configuration option that allows newly-created files to keep the IFIL resource in the old format, so that the data file can be opened by V11.5 and earlier. To use this option, add the following keyword to ctsrvr.cfg:
SUPPRESS_PATH_IN_IFIL NO
Note: This error will be seen only in environments in which a file is created on a server with the index file path enhancements and then is copied (replicated) to earlier versions of the server without this feature. As a best practice, FairCom always recommends keeping all servers in the same operating environment on the same release. If it is not possible to upgrade all servers to the same release, the keyword can be used as a last resort.
