Probe Specific Hardware Requirements
The websphere probe must be installed on systems with the following minimum resources:
  • Memory: 2-4GB of RAM. The OOB configuration of the probe requires 256MB of RAM.
  • CPU: 3-GHz dual-core processor, 32-bit, or 64-bit
Probe Specific Software Requirements
The websphere probe requires the following software environment:
  • Nimsoft Monitor Server 7.6 or CA Unified Infrastructure Management 8.0 or later
  • Robot 7.6 or later (recommended)
 For SOC functionality, Nimsoft Monitor Server 7.6 or CA UIM 8.0 or later and UMP 2.5.2 or later is required.
  •  Verify installation of Java JRE 6 or later.
  • WebSphere Application Server version 7.0 or later.
 WebSphere Community Edition (CE) is not supported.
Installation Considerations
The websphere probe can be installed on either a server running WAS or on a remote computer.
  • If installed on a server running WAS, install the relevant environment files on that server.
  • If installed on a remote computer, install the relevant environment files on that computer.
     Install WAS files/AppServer directory on the system where the probe is deployed for all WAS versions.
  • For WebSphere version 
    7.0
    8.0, 
    and 
    8.5,
     copy the 
    runtimes 
    and 
    plugins 
    folders from the WebSphere directory of the WAS.
  • If the OS on the remote computer with the probe and the WAS are different, copy the 
    etc
     and 
    lib
     folders from the WebSphere server to the remote computer.
  • If the probe is running on Windows OS, use the AppServer directory for Windows. Similarly, if the probe is running on Linux or Solaris, use the AppServer directory of the respective environments.
Verify Java Installation
Install Java version 6 or higher from IBM on the computer running the probe and include the java executable in the probe path. You can also copy the Java folder from the WebSphere server directory to the remote Windows computer on which probe is installed.
 Java JRE 6 and above is available with WAS 7.0 and above and you can use the same path for java_home.
On UNIX
You can configure the JVM and Java Home settings to install the probe on a UNIX OS.
 
Follow these steps:
 
  1. Set the JAVA_HOME environment variable to the directory in which IBM JVM is installed and export JAVA_HOME. For example,
    export JAVA_HOME=/usr/lib/jvm/ibm-java2-i386-50/jre/bin
  2. Ensure that the PATH variable includes $JAVA_HOME. For example,
    export PATH=$JAVA_HOME:$PATH
  3. Open a shell as a root user and run the command 
    java - version
    .
The output shows the IBM JVM version installed.
On Windows
You can configure the JVM and Java Home settings to install the probe on a Windows OS.
 
Follow these steps:
 
  1. To set the Java path, right-click 
    My Computer
     and select 
    Properties
    .
  2. In the 
    Advanced
     tab, click 
    Environment variables
    .
  3. Alter the 
    Path
     variable so that it also contains the path to the IBM Java executable.
  4. Open a DOS window and use the command 
    java - version
    .
    The output shows that IBM java version is installed. 
PMI
Enable Performance Monitoring Infrastructure (PMI) on the WAS for the probe to gather performance data. For more information about PMI, see http://www-01.ibm.com/support/knowledgecenter/SSTVLU_8.6.0/com.ibm.websphere.extremescale.doc/txsenablepmi.html?lang=en 
WAS Versions
Certain WAS versions prevent external PMI clients like the websphere probe to obtain correct PMI values from the server. The internal error is fixed in the following WAS versions:
  • For both WAS 5 and 6, the error is corrected.
  • For WAS 5, the error is fixed in version 5.1.1.10.
  • For WAS 6, the error is fixed in version 6.0.2.9, older versions like 6.0.2.5 and 6.0.2.7 contain the error.
Known Issues
This section describes the known issues of the probe.
  • After deploying websphere version 1.81, you cannot edit or save the resource in the IM console, after deleting an existing profile which has advanced alarming configuration. As a workaround, manually update the advance alarming configuration in the cfg file by modifying the alarm_on_resource key.
  • The probe stops functioning if you save the probe configuration with an invalid 
    Java Home
     path or 
    Libraries 
    path.
The Admin Console GUI of the probe has the following more limitations. 
  • The probe stops functioning if you do not refresh the web page after adding new resource.
  • The probe does not let you create Templates, Auto Monitor, and Auto Configuration. 
  • The probe does not support any other QoS except Default.
  • The probe does not support the Rescan for host option, which allows you to scan the profiles in the host server after a preconfigured interval of 15 minutes.
  • The probe displays the message "Controller: Max. Restarts reached for probe 'websphere' (command = )" and the probe fails to work. This is a known issue and occurs when multiple robots run on the same Linux machine. The probe works on one robot but fails on another robot. As a workaround, manually assign a value for the parameters -DNIM_SPOOLER_PORT and -DNIM_CONTROLLER_PORT using the Infrastructure Manager Raw Configure.
