I checked out the coding with this: Import sys >>> Sys.maxunicode >>> if> 65535: ... print 'UCS4 build' ... else: ... print 'UCS2 build' UCS2 build. The solution for this was to reinstall python but this: . / configure --prefix= / home/username/python-2.7.2 --enable-unicode=ucs4 I check again Import sys >>> Sys.maxunicode >>> if> 65535: ... print 'UCS4 build' ... else: ... print 'UCS2 build' UCS4 build worked on Red Hat 4.1.2-51 + python-2.7.2 Anonymous on "undefined symbol: PyUnicodeUCS4_Decode when Start OpsCenter" http://www.datastax.com/support-forums/topic/undefined-symbol-pyunicodeucs4_decode-when-start-opscenter#post-723 Fri, 18 Nov 2011 18:57:00 +0000 Anonymous 723@http://www.datastax.com/support-forums/ No worry, I'll have a try on RH5.5. mbulman on "undefined symbol: PyUnicodeUCS4_Decode when Start OpsCenter" http://www.datastax.com/support-forums/topic/undefined-symbol-pyunicodeucs4_decode-when-start-opscenter#post-722 Fri, 18 Nov 2011 18:49:19 +0000 mbulman 722@http://www.datastax.com/support-forums/ Unfortunately the lowest version of RHEL we support is 5.4. Is it possible for you to use a machine with 5.4+ as its OS? Keep in mind OpsCenter does not need to be installed on the same machine as DSE Server/Cassandra, so you don't have to worry about reinstalling those.

I'm eager to demo the OpsCenter to our workmates. If it doesn't work today, I'll demo Hive on a 3 node Cassandra cluster. My customer is <a href="http://www.bookfinder.com/" rel="nofollow">http://www.bookfinder.com/</a> and <a href="http://www.fillz.com/" rel="nofollow">http://www.fillz.com/</a> , hope I can persuade them to have DSE as their next big data project database platform.

I would recommend installing python via EPEL by running the following commands as sudo/root: rpm -Uvh <a href="http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm" rel="nofollow">http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-4.noarch.rpm</a> yum install python26 If that works, then you should be good to go with OpsCenter. Please don't hesitate to let us know if you have any more problems.

We're working on fixing that in the next release. Your initial output indicated python2.6. If you have since installed python2.7, but python2.6 is still available, you can workaround this by adding the following line to /etc/default/opscenterd: PYTHON=/usr/bin/python2.6 Let us know if that doesn't work or if you have any more questions.
