Oracle java.lang.OutOfMemoryError Tips Oracle Database Tips by Burleson Consulting February 12, 2015 Question: When installing Oracle it stops at 91% and I get the java.lang.OutOfMemory error. I see this message in my installation log file: java.lang.OutOfMemoryError <Operating System, R12, Technology, TroubleShooting | Tags: heap, oacore, oc4j, outofmemory, R12 | Recently we had encountered a situation, wherein end users where not able to get the R12 login page https://oraclepitstop.wordpress.com/2008/09/11/how-to-change-java-heap-size-in-r12-to-avoid-javalangoutofmemoryerror-java-heap-space-error/ and it just hangs, but all the opmn processess were up and running - adopmnctl.sh status gives status as alive for all the components viz., HTTP, oafm, oacore & forms. The same environment https://github.com/elastic/elasticsearch/issues/1043 was available and end users were able to access without any isuses 15 minutes before. This error happens only when multiple people login to the same page and perform simillar activity like permgen space employee self service form etc. So where and what exactly could be the problem. This is how we approached and resolved the issue. First we checked apache error log. The following error was reported in the error log. ============================================================== [warn] [client IP Address ] oc4j_socket_recvfull timed out [error] [client IP Address ] mod_oc4j: There is no oc4j process (for destination: application://oacore) available to service request. [error] outofmemoryerror permgen space [client IP Address] mod_oc4j: request to OC4J [servername:OC4J AJP Port Range for Oacore] failed: Connect failed ============================================================== Above error message does give us a hint that the problem is with oacore, but as i said earlier the oacore is alive according to opmn. Next, we verified the oacore log file. ($INST_TOP/logs/ora/10.1.3/opmn/oacore_default_group_1/oacorestd.err) Error Message in the file ======================================================= Exception in thread "OC4JMonitorThread" java.lang.OutOfMemoryError: Java heap space ======================================================= While checking the error in file, parallely we opened another window to see the CPU and memory usage and we could see one java process was taking more than 100% CPU. This process was spawned by the opmn -d process and the process id didnt match with the oacore process id. Hint: adopmnctl.sh status will give the status as well the process id. It looked like a end client java process. At this stage we had 3 options. 1. Kill the java process which is consuming high cpu. 2. Bounce oacore component 3. Adjust java (jvm) memory parameters Each of the above options has its own implications and advantages. To minimize the downtime we decided to kill the java processes, and the moment we killed the java pr

I have one elastic search server 0.16.1 and a java webapp client. Both of them discover themselves via broadcast. Everything works fine. Then I close my laptop, it goes to sleep. A while after that I reopen it. From that point I have errors on the elasticsearch server. Every 30 sec I have: [2011-06-17 20:27:49,752][WARN ][discovery.zen.ping.multicast] [McKenzie, Namor] failed to connect to requesting node [Magician][d-dJv8_MTCW_reKnhnYd-A][inet[/10.0.0.208:9301]]{client=true, data=false} org.elasticsearch.transport.ConnectTransportException: [Magician][inet[/10.0.0.208:9301]] connect_timeout[30s] at org.elasticsearch.transport.netty.NettyTransport.connectToChannels(NettyTransport.java:512) at org.elasticsearch.transport.netty.NettyTransport.connectToNode(NettyTransport.java:473) at org.elasticsearch.transport.TransportService.connectToNode(TransportService.java:126) at org.elasticsearch.discovery.zen.ping.multicast.MulticastZenPing$Receiver$1.run(MulticastZenPing.java:354) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:680) Caused by: java.net.ConnectException: connection timed out at org.elasticsearch.common.netty.channel.socket.nio.NioClientSocketPipelineSink$Boss.processConnectTimeout(NioClientSocketPipelineSink.java:37
