if we have a .ear application that we publish to WebLogic, however this application uses a fixed name to relate to the weblogic datasource. I need to create a multitenant environment for six different clients on the same WebLogic infrastructure, is there any way to resolve the sharing of six identical applications within the same weblogic which use the same name for the datasource, without having to change the application code?
35:08 JVM has the heap with it. JVM is running stuffs with it. I didnot get the part of pulling out JVM from the server (Running System.gc() in the server. How it is working).
Hello Vishnu! I meant that JVM can be pulled out from the Load Balancer pool. System.gc() can be triggered and then JVM can put back in to the pool. So that GC pause time will not impact customer transactions.
The same way you would without Kubernetes. I think you can also pass JVM arguments in the deployment file. For example, containers: - image: tomcat:9-jre8 name: tomcat env: - name: JAVA_OPTS value: "-Xlog:gc=debug:file=/tmp/gc.log:time,uptime,level,tags:filecount=5,filesize=100m"
Of course the most exciting feature of Eclipse Paho is that presentations like this are made to convince your boss/employer how easy all this is whilst providing almost ZERO documentation on how to get the job done for non-trivial projects. There is the Eclipse Paho Java Docs, but that is like trying to complete a jigsaw comprising of no corners, no straight edges and a box lid showing an image of each jigsaw piece and no image of the finished picture. Pure genius!
Interesting concept but the syntax is terrible, and his random monologue about energy efficiency was bollucks. Also, as a concept most investment banks, who this would be useful for, have things like Morgan Stanley's Optimus, which handle all this stuff whilst allowing users to write in native Scala.
I have a doubt, at 43:12 in that example, ArrayList will be increased by half of its original size right? for example, if the initial size of the List is 10, then it would be 15, when we try to insert 11th element.
Hello Laxman! Greetings. ArrayList size double when it's capacity limit is reached. Say if current capacity is 10 and when you try to add 11th element, ArrayList will double up. From it's current size of 10, it will become 20. Thanks.
@@ramlakshmanan5313 greetings!!! I just reverified. The grow method increases the list by half of its size. So it would be 15 when 11th element added. (This is for arraylist).
I have verified it using Java 8, in arraylist add method , it ensures the capacity before adding any new element. If the size exceeds it has a private method grow, which does the job of increasing the size. newCapacity = oldCapacity + (oldCapacity >> 1) So it would be "newCapacity = 10 + 5"
No Comment and only 31 thumps up since 8 years. You should make piercing or nail paint tutorials... *haha Na, thank you very much, it helped very good for understanding the history and possibility of Mqtt.. Best regard from Germany
This was great. Thanks! There was a reference to one or more talks/lectures about maintaining the order of messages. Is it possible to get links for those?
I love the warning at 8:24. If my memory serves me right, I recall one of the earlier waterfall model papers that had a similar warning, and got completely ignored. I cannot find the reference to it unfortunately :(.
You're right, it's here: www-scf.usc.edu/~csci201/lectures/Lecture11/royce1970.pdf. "I believe in this concept, but the implementation described above is risky and invites failure."
@@timklinke9669 Thank you very much!!! I've been searching for that quote for a while now :D. It comes very handy for a presentation I'm preparing at the moment. Thanks again!
