The Catalog dredger (dscat.nlm) is a search engine that dredges (searches) an NDS database for user-specified NDS objects and their properties and puts these in a catalog. The dredger is installed and during the NetWare server installation, under Other Products. You must then load the dredger NLM by typing
load dscat
at the NetWare server console.
One dredger can serve multiple catalogs. You can initiate dredges manually, or you can schedule them to be performed automatically.
The NetWare server object has a list of the catalogs for which the dredger is responsible.
