Our thick client desktop application provides a tool similar to Workspace Monitor, where our users can open a list of instruments with specific fields to monitor. Sometimes that list can be fairly large, up to 500 instruments. In profiling the memory usage in our desktop application we noticed that a large portion of the…
Hi All, I believe I am not using best practices when processing the response. for ex., chunking, paging, or streaming. Hence my application goes out of memory (breaching 500MB). I would like to get your advice on how to avoid an oom situation by processing the data efficiently. I tried looking at the examples on pages:…
Hi, I'm using EMA Java from Scala 2.11. I `registerClient()` 3,558 RICs at once by the following code: val client = new MyClient() // sub-class of OmmConsumerClient val rics = List("/1418.T", ...) // Ordinary stocks in Tokyo Stock Exchange, whose length is 3558 rics.map { ric =>…
Hi, this is my code : instrumentsInQuestion.forEach(instrument -> arrayI.add(EmaFactory.createOmmArrayEntry().codeState().ascii(instrument.getRootSymbol()))); arrayView.add(EmaFactory.createOmmArrayEntry().intValue(1)); batchView.add(EmaFactory.createElementEntry().array(EmaRdm.ENAME_BATCH_ITEM_LIST, arrayI));…
Hell, everyone, is there any method to know the size of RefreshMsg or UpdateMsg object ? Currently in onRefreshMsg & onUpdateMsg, I will create a new object using new operator and push back into an internal queue that has no size limit that will be popped by a decoder thread for processing. But on market open time, the…
We need to switch between hosts in case of unavailability. To do this, we recreate OmmConsumer with new settings (only one OmmConsumer exists at a time). If all hosts are unavailable, the memory leaks out exponentially during 30 attempts, which leads to the process crash. It is empirically established that the memory leak…
We are using RFA8 libraries to connect to Reuters. We have observed that the memory utilization of our service has increased and it is gradually increasing daily whenever we access reuters. Seems a memory leak with RFA8. Please advise as we are afraid that our service might crash anytime due to OutOfMemoryException
OmmServerBaseImpl::uninitialize() accesses variable "_pRsslServer" after calling rsslUninitialize(), so that free'd memory is accessed.
We are currently using RFA.NET 8.1.0 and we are seeing a drastic increase in our memory usage while subscribing to around thousands RICs. We've attempted to reduce the memory usage by making use of Dynamic Views to reduce the number of Field Entries we get back and we've moved our processing logic out of the ProcessEvent()…
Dear sir, We are using one EMA consumer batch application to collect markets, stocks etc. After a while, application breaks and it is mostly doing so when the whole markets are open. It is retaining heap memory up to 3GB. We have already increased the java max heap size to 4GB. The class holding the heap is…
