Show EC2 Instances across all Regions

July 28, 2017 by Leave a Comment

A note to myself (might be useful to you as well):

for region in `aws ec2 describe-regions --output text | cut -f3`
do
     echo -e "\nListing Instances in region:'$region'..."
     aws ec2 describe-instances --region $region
done

OSB / SOA Suite 12c Domain Types

November 28, 2016 by 1 Comment

OSB / SOA Suite 12c Domain Types

screen-shot-2016-11-30-at-16-22-10Let me explain you some news about the domain types in 12c, since some of my colleagues were fiddling around with this. Due to the new quickstart installer for SOA Suite and OSB 12c there are more domain types available now for SOA Suite and OSB12c that you need to understand. The following options describe those types with added comments of when the make sense.

 

 

Options:

  1. The integrated domain that gets generated by JDeveloper if you run a project. Sometimes it is called default domain. This domain is bound to JDeveloper. Whenever you quit JDev, the domain shuts down. The downside is that this domain always supports OSB and SOA Suite, so a bit of waste of resources if you are only after OSB . This is the easiest solution for your first steps because no manual domain creation is required and JDev does it all for you.
  2. A standalone domain. This is the new and interesting option, because a standalone domain uses the Java DB and does not require you to run the RCU utility. Still a standalone domain is running independent from JDeveloper 12c, so you could you use this type of domain for development with OSB web console.You create the domain by setting the QS_TEMPLATES environment variable and running qs_config.sh, then create an application server connection with JDev, use the standalone server option in the application server connection wizzard, and point it to the standalone domain.
    You will be able to use “Deploy” from JDeveloper, but unfortunately not “Run as”.
    There are more benefits to a standalone domain not mentioned in the official documentation: Whereas the integrated domain includes everything needed for SOA suite you can restrict a standalone domain to Service Bus only and therefore reduce the number of internal deployments from 304 to 278 which will save you startup time.
  3. A compact domain can be used with quickstart. Also compact domains are targeted for development. This domain will be compatible with add-ons such at MFT, OES, etc. Note that you have to specify a special parameter CONFIG_JVM_ARGS=-Dcom.oracle.cie.config.showProfile for this option to be visible in the configuration wizzard.
    Since you can use it with an compatible Oracle DB, the necessary schemas have to be created with the RCU utility. Note: A compact domain is a developer domain consisting of a single admin server and no managed servers.
    The opposite of a compact domain is called extended domain where resources are deployed on a cluster of managed servers. Use extended domain for environments such as test, integration, load test, prod. These environments are distributed and clustered typically due to HA requirements.

Conclusion

It is important to understand the various domain types and to choose the correct domain type for your requirements. You can strip down a standalone domain to be OSB only, then make sure to select Integrated Servers if you want to deploy directly from JDev to it.

Zero Downtime, REST, Domain Partitions / Multi Tenancy, Elasticity and WLDF. WebLogic 12.2.1 (12c)

July 4, 2016 by 2 Comments

I just finished a two week long hands-on consulting session for some pretty experienced application managers and architects.

In 5 days we explored WebLogic 12.2.1 extensively:

  • Zero Downtime
  • REST
  • Domain Partitions / Multi Tenancy
  • Resource Group Management
  • Java Mission Control
  • WLST
  • Elasticity
  • JMS Clustering
  • WLDF

Here is some feedback from the group. You can tell we had fun, although we worked very hard.

This is how a happy group looks like.

People seemed to be happy, here is what they liked.

Cloud Survey: Computerworld Quotes

October 13, 2014 by Leave a Comment

Update as of Nov 2014: You can get the whole survey now from here (registration required though).

 

Cloud is more popular than ever. Even the slower, more traditional software vendors now pick up the concepts I wrote about back in 2011. Keep going!

Find attached some quotes from the Computerworld magazine.

RESTful WebLogic Monitoring of Servers, Applications, JDBC and JMS with Jolokia

April 19, 2012 by 6 Comments

[This posting will be a part of my upcoming WebLogic 12c book]

This article is part II of III. Make sure you read part I explaining the basics of monitoring WebLogic with WLST, the WebLogic 12c REST-ful management API and the open source framework Jolokia.

There will be a part III in a few of days, explaining how to use j4psh with WebLogic. j4psh is a JMX shell that resembles WLST in interactive mode but includes features such as syntax highlighting and tab-completion of commands and MBean names. j4psh is highly useful to interactively find out the correct MBean names used for the requests below.

WebLogic with Jolokia

Did you ever wonder how to retrieve the configuration values for a WebLogic managed server, runtime data of a JDBC connection pool or the number of messages in a particular JMS queue with a fast and simple HTTP GET?

The examples show typical use cases for monitoring a WebLogic domain with the following configuration:

– Admin server running at localhost:7001
– Managed server with name surf1 running at localhost:7003
– JDBC datasource with the name emergencyDB and associated connection pool (target set to surf1)
– JMS configuration with a JMS server surfJMS running on managed server surf1, a module surfJMSModule containing a queue name jms/ShippingRequestQueue (target of JMS server is surf1, JMS module subdeployment set to surfJMS)
– A deployment of a web service with the name SubmitOrder and target AdminServer and surf1.

An installation of Jolokia with target set to all server of the domain is recommended to follow the examples in this part.

Note, that without the ?ignoreErrors=true parameter the request would fail with an “NoAccessRuntimeException” because you cannot access the SSL keystore passphrases without proper authentication. Authentication is easily possible, but beyond of the scope of this article.

JMS: Find all JMS Servers with Target set to Managed Server Running at localhost:7003


http://localhost:7003/jolokia/search/com.bea:Type=JMSServerRuntime,*


which returns the JMS server surfJMS:


{
   "timestamp":1334776840,
   "status":200,
   "request":{
      "mbean":"com.bea:Type=JMSServerRuntime,*",
      "type":"search"
   },
   "value":[
      "com.bea:Name=surfJMS,ServerRuntime=surf1,Type=JMSServerRuntime"
   ]
}



JMS: Runtime Properties for a Particular Queue


Request the MessagesCurrentCount, MessagesHighCount and MessagesReceivedCount for a queue with the name jms/ShippingRequestQueue (note the “!” is used in the URL to escape the “/” character in the queue name) in a JMS module with the name surfJMSModule (note that JMS module and queue name are typically separated in the MBean Name attribute with a “!” which has to be escaped by another “!”).


http://localhost:7003/jolokia/read/com.bea:JMSServerRuntime=surfJMS,Name=surfJMSModule!!jms!/ShippingRequestQueue,ServerRuntime=surf1,Type=JMSDestinationRuntime/MessagesCurrentCount,MessagesHighCount,MessagesReceivedCount


which returns the following JSON structure.


{
   "request":{
      "attribute":[
         "MessagesCurrentCount",
         "MessagesHighCount",
         "MessagesReceivedCount"
      ],
      "mbean":"com.bea:JMSServerRuntime=surfJMS,Name=surfJMSModule!jms/ShippingRequestQueue,ServerRuntime=surf1,Type=JMSDestinationRuntime",
      "type":"read"
   },
   "status":200,
   "timestamp":1334775025,
   "value":{
      "MessagesCurrentCount":0,
      "MessagesHighCount":1,
      "MessagesReceivedCount":3
   }
}




The output for the queue monitoring shows that there was a total of 3 messages sent, with a maximum of 1 in the queue (because of a deployed receiver retrieving the messages immediately) and currently 0 message in the queue.
