multithreading - Application deployed in weblogic instance is running Slow -


my application deployed in weblogic instance getting slow sometimes. @ time, it's hitting error related stuck thread time in managed server log. initially, when noticed this, did research , increased value of max stuck thread time 800 seconds in place of 600 seconds. but, didn't fix issue. got following error again.

watchrule: (severity = 'error') , ((msgid = 'wl-000337') or (msgid = 'bea-000337')) watchdata: message = [stuck] executethread: '58' queue: 'weblogic.kernel.default (self-tuning)' has been busy "812" seconds working on request "http request information: weblogic.servlet.internal.servletrequestimpl@42f38088[post /****/faces/index.jsf] ", more configured time (stuckthreadmaxtime) of "800" seconds in "server-failure-trigger". stack trace:   oracle.jbo.pcoll.pcollnode.objectat(pcollnode.java:1753)   oracle.jbo.pcoll.pcollnode.objectat(pcollnode.java:1753)   oracle.jbo.pcoll.pcollection.elementat(pcollection.java:839)   oracle.jbo.server.querycollection.get(querycollection.java:2556)   oracle.jbo.server.viewrowsetimpl.getrow(viewrowsetimpl.java:5540)   oracle.jbo.server.viewrowsetiteratorimpl.getrangeindexof(viewrowsetiteratorimpl.java:1179)   oracle.jbo.server.viewrowsetiteratorimpl.notifyrowupdated(viewrowsetiteratorimpl.java:3491)   using adf 12c application development weblogic version: 12.2.1 in windows server database : oracle 11g jdk version : 1.8-65

can please advise me on reason , possible solution issue? in advance.

increasing stuck threads time not resolve issue. stack trace looks application may reading file. there can different reason slowness

1) may file reading large 2) may slow network 3) may io latency

if possible can introduce debugging messages in application. provide details on process application running. if running application on linux/unix environment can monitor process activity inside /var/proc directory

c# - Check Keyboard Input Winforms -

i wondering if instead of doing this protected override void onkeydown(keyeventargs e) { if (e.keycode == keys.a) console.writeline("the key down."); } i set bool method , this: if(keydown(keys.a)) // whatever here i've been sitting here ages trying figure out how it. can't wrap head around it. in case wondering, plan call bool inside different method, check input. since want perform action after pressing key, using keydown event enough. but in cases suppose want check if specific key down in middle of process, can use getkeystate method way: [dllimport("user32.dll", charset = charset.auto, exactspelling = true)] public static extern short getkeystate(int keycode); public const int key_pressed = 0x8000; public static bool iskeydown(keys key) { return convert.toboolean(getkeystate((int)key) & key_pressed); } you should know, each time check key state using example iskeydown(keys.a) method returns true if ke...
