JNA is listed as a "Recommends" dependency in DSE as it is with the stock Apache Cassandra packages. It is recommended to install on production machines as it provides access to native memory and IO functions for higher performance and access to off-heap caching. libmx4j is only required if you would like to expose the JMX attributes via HTTP directly from Cassandra is detailed here: <a href="http://wiki.apache.org/cassandra/Operations#Monitoring_with_MX4J" rel="nofollow">http://wiki.apache.org/cassandra/Operations#Monitoring_with_MX4J</a> Please let us know if you have any more questions. thobbs on "No command 'dse' found" http://www.datastax.com/support-forums/topic/no-command-dse-found#post-661 Fri, 11 Nov 2011 18:39:24 +0000 thobbs 661@http://www.datastax.com/support-forums/ No, those libraries are not required to start DSE. Did you try running the commands that Nate suggested? In Unix/Linux, to run executables that are not in your path (directories like /bin, /usr/bin, /usr/local/bin, etc), you need to prefix the filename with path (which is just './' if it's in the current directory).

Is it because they have already been included as part of the package install here: <a href="http://www.datastax.com/docs/1.0/datastax_enterprise/install_dse_packages#install-dse-pkg" rel="nofollow">http://www.datastax.com/docs/1.0/datastax_enterprise/install_dse_packages#install-dse-pkg</a> If they are not included, which directories should they be installed at? Can I use the instructions here: <a href="https://sites.google.com/a/techlabs.accenture.com/cassandra/home/installcassandra07" rel="nofollow">https://sites.google.com/a/techlabs.accenture.com/cassandra/home/installcassandra07</a> zznate on "No command 'dse' found" http://www.datastax.com/support-forums/topic/no-command-dse-found#post-635 Tue, 08 Nov 2011 21:01:03 +0000 zznate 635@http://www.datastax.com/support-forums/ By default, you have to invoke the command like so: ./dse Or from a directory up: ./bin/dse You can add ~/datastax/dse-1.0-3/bin/dse to your path as well so you can invoke it directly. joaquin on "No command 'dse' found" http://www.datastax.com/support-forums/topic/no-command-dse-found#post-634 Tue, 08 Nov 2011 20:59:56 +0000 joaquin 634@http://www.datastax.com/support-forums/ Hello, Were you perhaps looking for dsetool? <a href="http://www.datastax.com/docs/1.0/datastax_enterprise/about_hive#setting-the-job-tracker-node-for-hive" rel="nofollow">http://www.datastax.com/docs/1.0/datastax_enterprise/about_hive#setting-the-job-tracker-node-for-hive</a> Anonymous on "No command 'dse' found" http://www.datastax.com/support-forums/topic/no-command-dse-found#post-633 Tue, 08 Nov 2011 20:58:06 +0000 Anonymous 633@http://www.datastax.com/support-forums/ usr@ubuntu:~/datastax/dse-1.0-3/bin$ dse --help No command 'dse' found, did you mean: Command 'dsh' from package 'dsh' (universe) Command 'ds9' from package 'saods9' (universe) dse: command not found
