Review and merge pull request https://github.com/OpenNMS/opennms/pull/458 which resolves this issue for RHEL/CentOS and Debian/Ubuntu.

Use JRRD2 but from what jeffg has said it will only be supported for v.17 forward even though we can attest to its operational functionality with Meridian and v.16 from when David Hustace and Jeff G were here onsite at USPTO.

The main difference between jrrd and jrrd2 is that jrrs2 is multi-threaded. So, it is going to be a lot faster than jrrd.

How to configure it ? Exactly on the same way you configure jrrd.

After installing the jrrd2 RPM, you can obtain the relevant information:

[root@localhost ~]# rpm -ql jrrd2
/usr/lib64/libjrrd2.so
/usr/share/java/jrrd2-api-2.0.1.jar

Then, edit rrd-configuration.properties and add the following:

org.opennms.rrd.strategyClass=org.opennms.netmgt.rrd.rrdtool.MultithreadedJniRrdStrategy
org.opennms.rrd.interfaceJar=/usr/share/java/jrrd2-api-2.0.1.jar
opennms.library.jrrd2=/usr/lib64/libjrrd2.so
