OPNBI Cluster Manager Setup

This Document explains how to set up Cluster Manager in OPNBI for Clustering instances.

Prerequisites​

Cluster Manager jar ACM-0.0.1-SNAPSHOT.jar, hazelcast-all-4.2.jar & opnbi.jar [latest release], application.yml file

Procedure for clustering:

You will find all prerequisites in ACM Files.zip Here

  1. Unzip this folder and place it in storage drive:/OPNBI/ folder

  2. Stop OPNBI tomcat server till changes are done.

  3. Go to the ACM folder you have extracted, you will find all opnbi.jar & hazelcast.jar files.

  4. Copy these all jar files and paste it in C:/OPNBI/tomcat/webapps/opnbi/WEB-INF/lib/ path.

  5. open config.json file copy whole cluster property, for that go to C:/opnbi/repository/Config/ folder and open existing config.json file.

  6. Paste copied files inside the config.json file outside of general settings as shown in the image below, 

"cluster" : {
    "checked" : true,
    "description" : "AIV Clustering",
    "properties" : [ {
      "name" : "cname",
      "displayName" : "Cluster Name",
      "defaultValue" : "OPNBI",
      "type" : "text",
      "placeholder" : ""
    }, {

      "defaultValue" : "5702-5720",
      "type" : "text",
      "placeholder" : ""
    }, {
      "name" : "totalTasks",
      "displayName" : "Total Tasks",
      "defaultValue" : 10,
      "type" : "text",
      "placeholder" : ""
    }, {
      "name" : "maxbackoff",
      "displayName" : "Max backoff time",
      "defaultValue" : 1800000,
      "type" : "text",
      "placeholder" : ""
    }, {
      "name" : "multiplier",
      "displayName" : "Multiplier",
      "defaultValue" : 2,
      "type" : "text",
      "placeholder" : ""
    }, {
      "name" : "connectiontimeout",
      "displayName" : "Connection timeout",
      "defaultValue" : 60000,
      "type" : "text",
      "placeholder" : ""
   
    } ]
  },
info

Make sure property “checked”: true otherwise clustering will not work.

  1. Save and close it

  2. Now open a command prompt as administrator, change directory to ACM folder.

  3. Run the ACM jar file using this command, and wait for the server to start.

java -jar ACM-0.0.1-SNAPSHOT.jar --spring.config.location=application.yml
  1. You will see the log “Started Application in –some- seconds (JVM running for 11.581)” when the server is started.

Docusaurus Slash Introduction

  1. Once the server is started, start OPNBI by running batch file “start_opnbi.bat” and wait for the server to start as the server is started, you can use OPNBI.
info

As cluster property “checked”: true you cannot start OPNBI without starting the ACM server.
