In several of my projects for Oracle WebLogic Server and Oracle Fusion Middleware Environments a main topic is the monitoring.
Oracle provides with the Oracle Enterprise Manager Cloud Control are really powerful solution to monitor Oracle WebLogic Server and Oracle Fusion Middleware Environments, but the disadvantage is the huge license cost for the necessary Management Packs for Oracle WebLogic / Fusion Middleware. Moreover in many small to midrange sized environments the Oracle Enterprise Manager Cloud Control can be an overkill and due to the license costs for the Management Packs a no-go.
There are several solutions on the market, some commercial and some open source, for Oracle WebLogic Server Monitoring.
I will show you a short test case, how to consume Oracle WebLogic Server RESTFul Management Services with the so called ELK Stack (Elasticsearch / Logstash / Kibana). How to setup the ELK stack, just check Google or the documentation on elastic.co Read the complete article here.

If you are worried about your password showing up in clear text in the startup scripts, you can use the storeUserConfig command to generate encrypted userconfigFile and a userKeyFile that you can then use in the „nmConnect“ and „connect“ command.

Place there two files on the protected place and decide to set right permissions

Create storeUserConfig for the Node Manager

Start wlst via the shell script $ORACLE_HOME/oracle_common/common/bin/wlst.sh:

/u01/app/oracle/product/FMW/Oracle_Home/oracle_common/common/bin/wlst.sh

Connect to Node Manager (important note: the Node Manager must be running!): Read the complete article here.

Several Weblogic components like EJBs, Datasources and Queues are accessed using JNDI-lookups. In default Weblogic configurations, the JNDI-Tree can be accessed without any kind of authentication. This is far from ideal, because any process, inside or outside the Weblogic container is capable of invoking these components. Only Datasources have an extra layer of security and can only be used remotely by activating the property “weblogic.jdbc.remoteEnabled”.

In this blog entry I will not only show how to secure the JNDI-Tree but also what this means to the development of components such as Session EJBs, Message Driven Beans and external frameworks.

1. Securing the JNDI-Tree lookups

In Weblogic it is possible to secure single JNDI addresses, a group of addresses and the whole JNDI-Tree. There are two ways to do this: the administration console and with WLST

1.1 Administration Console

  • In Environment->Servers-> admin_server-> View JNDI Tree

Oracle recently made their ‘Kafka on Cloud’ service available: the Event Hub cloud service – offered as part of the Big Data Compute Cloud Service. In this article, I will briefly show the steps I went through to get up and running with this service. To be frank, it was not entirely intuitive – so this may be handy the next time I have to do it or perhaps when you are struggling. One obvious point of confusion is the overloaded use of the ‘service’ – which is applied among others for Kafka Topics.

The steps are:

  1. Initialize the Oracle BigData Compute CS | Oracle Event Hub Cloud Service – Platform – -expose REST Proxy
  2. Create Network Access Rule to enable access to the Event Hub Platform instance from the public internet
  3. Create a Event Hub service instance on the Event Hub Platform – corresponding to a Kafka Topic
  4. Inspect Event Hub using PSM
  5. Interact with Event Hub through CURL
  6. Create application (e.g. NodeJS) to access the Event Hub Service (aka Kafka Topic): produce message, create consumer, consume messages (through the REST proxy) – discussed in a subsequent blog article

Initialize the Oracle BigData Compute CS | Oracle Event Hub Cloud Service – Platform – -expose REST Proxy

From the Dashboard, open the BigData Compute Cloud Service. Open the dropdown menu. Select option Oracle Event Hub Cloud Service – Platform. Read the complete article here.
