Compress the Data Index
You can configure the IDOL Content component to compress the nodetable
directory to reduce the disk footprint, by using the NodeTableCompression configuration parameter.
NOTE: If you change the compression method after you have started the server, the compression applies only for operations that index new data or rewrite existing data (such as DREREPLACE).
To compress or change the compression of the whole index, you can run a DRECOMPACT operation with the NodeTableCompactWindowKB
NodeTableCompactWindowKB parameter set.
For more information about the NodeTableCompression option, and the compression method to use, refer to IDOL Expert.
