Using the rck2 utility 153
The VDB optimization option optimizes the packing of a collection’s VDBs. When VDBs are
built during normal indexing operations, the segments are not stored sequentially in the one-file
VDB file system. As a result of VDB optimization, performance can be improved by reserializing
the packed segments in the VDBs so that all segments are contiguous, and VDBs can grow in size.
Optimized VDBs can grow up to 2 gigabytes in size, as opposed to the maximum 64 megabytes
for an unoptimized one.
Using this option might degrade your indexing performance when certain indexing modes are set
for the collection.
Performance tuning options
The mkvdk utility provides performance tuning options, as the following table describes:
Using the rck2 utility
The rck2 command-line utility lets you search collections associated with a Verity server. The
rck2 executable file, which starts the rck2 utility, is located in the
platform /bin directory. For more
information on the specific location of this directory, see “Location of Verity utilities”
on page 142 .
The rck2 syntax
Use the following syntax to start rck2 from the command line:
rck2 -server <servername> -port <portno>
For example:
c:\cfusionmx7\verity\k2\_nti40\bin\rck2 -server localhost -port 9901.
The following table describes rck2 syntax elements:
Option Description
-maxfiles num Sets the maximum number of files that the mkvdk utility can have open at once.
The default is 50.
-diskcache num
Sets the size of the mkvdk disk cache in kilobytes. The default is 128.
Syntax element Description
-server <servername> The server name for K2 Server to which to attach. The server name is
defined in the k2server.ini file. The rck2 utility searches the collections
attached to this server.
-port <portno>
The port number where K2 Server (specified by
-server
) is running.
