OSB: Disable Chunked Streaming Mode recommendation by Martien van den Akker

Intro

These weeks I got involved in a document generation performance issue. This ran for several months, maybe years even. But it stayed quite unclear what the actual issue was.
Often we got complaints that document generation from the front-end application (based on Siebel) was taking very long. End users often hit the button several times, but with no luck. Asking further, it did not mean that there appeared a document in the content management system (Oracle UCM/WCC). So, we concluded that it wasn’t so much a performance issue, but an exception along the process of document generation. Since we upgraded BI Publisher to 12c, it was figured that it might got something to do with that. But we did not find any problems with BI Publisher, itself. Also, there was an issue with Siebel it’s self, but that’s also out of the scope of this article.

The investigation

First, on OSB the retry interval of the particular Business Service was decreased from 60 seconds to 10. And the performance increased. Since the retry interval was shorter, OSB does a retry on shorter notice. But of course this did not solve the problem.
As Service developers we often are quite laconical about retries. We make up some settings. Quite default is an interval of 30 seconds and a retry count of 3. But, we should actually think about this and figure out what the possible failures could be and what a sensible retry setting would be. For instance: is it likely that the remote system is out of order? What are the SLA’s for hoisting it back up again? If the system startup is 10 minutes, then a retry count of 3 and interval of 30 seconds is not making sense. The retries are done long before the system’s up again. But of course, in our case sensible settings for system outage would cause delays being too long. We apparently needed to cater for network issues.
Last week our sysadmins encountered network failures, so they changed the LoadBalancer of BIP Publisher, to get chunks/packets of one requests routed to the same BI Publisher node. I found SocketReadTimeOuts in the logfiles. And from the Siebel database a query was done and plotted out in Excel showing lots of request in the  1-15 seconds range, but also some plots in ranges around 40 seconds and 80 seconds. We wondered why these were. Read the complete article here.

Undeploy non default, retired or inactive soa suite composites using java by Hugo Hendriks

When building a lot of soa suite composites, your environments end up with many different versions. So we might end up with 3 LocationService composites with versions[1.0.0.0], [1.0.1.0] and [1.0.2.0] which is the default. This takes up resources and clutters the EM. So you might want to have a way to remove these easily with having to go to the EM and manually uninstalling all of them with the risk of mis-clicking. In this blog I will show an easy way to undeploy old soa composites using java.

At first I looked at WLST and there is a sca_undeployComposite but we don’t want to specify each composite seperate. We just want to look through al composites and see which ones aren’t default and then undeploy them. There is also a sca_listDeployedComposites but I couldn’t find a way to pipe the output of this to an array to be able to work with it. So I just did what I know best and write it in Java. It basically does the same. Just connect through JMX, look up all the composites and check if they are: Read the complete article here.
