Setting environment variables

Environment variables are specific preset values that establish the working environment of the probe.

The following table indicates the minimum Java requirement to run the probe.

Table 1. Java version required by probe

Spectrum Version

Java Version


Spectrum Version 9.4

Java 7

JRE 7 available with OMNIbus 8.1

Spectrum Version 10.0

Java 8

Omnibus 8.1 is not available with JRE 8.

The selection of the Java Runtime Environment (JRE) used for the probe's runtime environment adheres to the following order of precedence:

  1. The JRE specified by the $NCO_PROBE_JRE environment variable.
  2. The JRE specified by the $JAVA_HOME environment variable.
  3. The most recent JRE version available to Netcool/OMNIbus.
Note: If the version of Netcool/OMNIbus that you are using did not come with the minimum required Java version, you must perform one of the following actions before running the probe:
  1. Download and install the required version of JRE from the Oracle download page.
  2. Edit the $OMNIHOME/probes/java/nco_p_ca_spectrum_corba.env file to add the latest Java directory to the $NCO_PROBE_JRE environment variable.
