The Index Utility Ixutil

The ixutil utility supports reorganizing an SPD Server hybrid index to improve query
performance and minimize disk space. The utility also prints the disk usage statistics or the
contents of indexes.

<data set1,column1> < data set2,column2> ...
-libpath
< number of parallel join work units > ;
Create a join index for a pair of data sets in the same domain that can be used by the
SPD Server Parallel Range Join optimization. The columns must already be indexed.
The recommended number of parallel join work units is two times the number of
processors.
<data set1,column1> < data set2,column2> ...
-libpath
Delete a join index.
List the join indexes in a domain.
