Getting Started with Coherence*Web in Web. Logic Server 1. 2. Introduction. Coherence*Web is a great feature which allows you to store your HTTP sessions in a Coherence Cluster.
This will ensure that the manages servers in both WLS clusters are associated with a common set of Coherence caching services. Storage. Tier – 2 Coherence managed servers storage. Create a Coherence Cluster. Navigate to Domain Structure then Environment and click on Coherence Clusters. Give it a name and leave the defaults.
Create the Web. Logic Clusters, place both your WLS clusters in the Coherence cluster and configure Coherence storage for each WLS cluster. Navigate to the Clusters link and create 2 clusters. Storage. Tier and Client.
Tier. Leave the defaults as is. Select the Storage. Tier cluster and click on the Coherence tab. Select your newly created Coherence cluster and click Save. Select Coherence Web Local Storage Enabled to ensure any managed servers in this cluster store Coherence*Web session data.
Click Save to continue. Select the Client. Tier cluster and click on the Coherence tab. Select your newly created Coherence cluster and click Save.
De- select Local Storage Enabled and click Save. We don’t want to actually store HTTP sessions in the client tier, but we want to be able to access them. Create Managed Servers to populate each WLS cluster. Note the managed servers added to each cluster will inherit their Coherence config form the cluster wide values which you set above. This means the Coherence managed servers added to the Storage Tier WLS cluster will be providing session storage while the Regular managed servers in the Client Tier WLS cluster will be coherence clients.
Navigate to the Servers link. Create a new managed server called client. Client. Tier as well as the machine you created.
Set the listener port to 7. Create a new managed server called storage.
Storage. Tier as well as the machine you created. Set the listener port to 7. Clone storage. 1 and name it storage. Start up you managed servers.
Deployment. Now we need to Deploy applications which will demonstrate session fail- over and management features we have configured. Cluster. JSP – (optional) shows session failover. Sample- applications (optional) shows session management features. Deployment 1 Cluster. JSPDeploy Cluster.
JSP as a directory deployment rather than a archive deployment. This will make modifications of the deployment descriptors easier. Console navigate to the Deployments page.
Click the Install button and navigate to the applications directory where you should find the clusterjsp- ear directory. Click the select button to the left of the folder and click the Next button at the bottom of the page. Leave Install as application selected and click Next. Select Client. Tier cluster and click Next. Leave the defaults and click Finish. Test the application. In a browser access the clusterjsp with the following url: http: //yourhostname: 7.
Follow the instructions at the bottom of the displayed page. To access the page from the other server in the client tier cluster change the the port number in the browser and hit enter. Notice the session attribute and value which you had added are not present because we have not yet enabled Coherence*Web. Enable Coherence*Web Session Storage. Create a WLS deployment descriptor to enable Coherence*Web sessions by saving the text below into a new file called: < wls install.
Console navigate to the Deployments page. Update the deployment by click the Select button next to the clusterjsp- ear application and click the Update button. Repeat your previous test. This time you should see your Session attributes are present regardless of which client tier server you access.
Stop the servers one at a time in each tier and notice when the session data is no longer available. Note. For a multi- machine Web.
Logic app- tier cluster, to ensure all machines have a common cookie path for the app, you must access the cluster jsp through a load balancer. Sample using the test- only lb. It’s that simple!
Next, run the application using the URL: http: //your- ip- address: 7. Here we are just using the HTTP session and no Coherence specific code is used. You can experiment with the other links in the sample application. You could just as well browse the MBean tree, but the Plug- in shows this in a nicer format. For detailed information on how to install and connect jvisual.
VM to a Web. Logic Server environment please see the Coherence Incubator site. Install the Coherence Visual. VM plugin brief steps. Download the latest pre- built plug- in module (NBM) from search.
Start JVisual. VM by running jvisualvm or jvisualvm. Windows) from the bin directory under your Java home. Choose Tools - > Plugins. Click on the . If you are on Windows then please ensure the command is on one line.). JAVA. Use the following for the connection URI and enter the credentials for the Web. Logic Server Admin: (the following should contain no spaces)service: jmx: iiop: //hostname: port/jndi/weblogic.
Once you have opened the newly created connection you will see the . You can see from the screenshot below, that you are able to view the number of sessions created and any session- reaping, which is cleaning up of old sessions. Conclusion. It may have seemed that we went though a few steps above, but I wanted to show the evidence of the HTTP sessions begin stored Coherence*Web. The high- level steps to setup Coherence*Web are pretty straight forward: In your Web. Logic domain, create a Coherence Cluster. Create a Client Web.
Logic Server Cluster and managed servers for your web apps and associate with the Coherence cluster as storage- disabled. Create a Storage Web. Logic Server Cluster and managed servers for your data tier. Make this storage- enabled and also check.
The Oracle Coherence Incubator - Overview. Provides a JVisual. VM Plug- in allowing developers to view. JMX to a. Coherence cluster. For monitoring, managing and.
Oracle's Enterprise Manager, Fusion Middleware. Control and/or other 3rd party tools. Distribution. The JVisual. VM Plug- In is distributed in the Net.
Beans Module (nbm) file. Summary graphs show total cluster. Coherence. Machines. Displays a list of the physical machines that make up the Coherence cluster as well as.
Members Displays the full list of Coherence members/nodes including individual publisher/ receiver. Services. Displays information about the running services including partition counts and status. HA values. To get the correct information to be displayed for memory usage, you must be using the binary. If you select a cache, on the next data refresh you will see detailed information.
Proxy Servers. If your cluster is running proxy servers for Coherence*Extend, this tab displays information about. Coherence*Web. If your cluster is configured for Coherence*Web, this tab displays information about the number. HTTP sessions being stored as well as other information.
On any of the tables you are able to right- click and export the current data from that table as CSV. JMX Monitoring Considerations. Important. When using JMX to retrieve statistics from Coherence clusters which have large number of members. With this in mind it is recommended to change the 'Management Refresh'. This can be achieved by using the following system property on your cache servers: -Dtangosol.
See Oracle Documentation for more information. JVisual. VM has screen refresh intervals setup in the Preferences. The plug- in has been built to only refresh data from the. Coherence MBean server by default every 3. Combined with the above management refresh setting, this should.
Coherence cluster. For development or demo purposes only, if you wish to refresh data more often, you can add the following. JVisual. VM command line. To connect to the Domain Runtime MBean server via JVisual. VM requires a few more additional steps: Source your Web. Logic Server Environment.
You should use . I am using Linux for my example. See Oracle Documentation. JMX in Coherence. Information does not display on tabs Navigate to 'About Java Visual. VM' menu item and click on 'Logfile' to see if there are any.
