Select the Inspection tab and then select run All Inspections.YourKit is an excellent way to drill down inside the Java JVM Java to capture Garbage collection,CPU and memory statistics.DESCRIPTION YourKit is a tool for profiling Java.NET applications.It can collect memory, CPU threading as well as JVM garbage collections.
This is a useful tool to drill further down in to the Java processes to help identify blocking and performance issues. You can monitor threading processes as well as TSQL statements. Required Software 1. SUP 2.x.x or higher. YourKit Java Profiler 2013 Release. Read Write Permissions. Assumption This document assumes you have a working SUP environment. You have downloaded the YourKit from Have Administrator rights to the Operating System and Sybase Unwired Server. Solution You need to configure Your Kit java profiler. Yourkit Java Profiler Guru Download YourKit FromDownload YourKit from 2. Get a YourKit evaluation license. Install yourKit. 4. Add C:Program Files (x86) YourKit Java Profiler 12.0.6binwin64; Figure 1 4. Stop the SUP server from the Windows Services. Backup Sybase UnwiredPlatform Servers UnwiredServer binmlsrv.ext.ini 6. Edit Sybase UnwiredPlatform Servers UnwiredServer binmlsrv.ext.ini 7. Add - agentlib:yjpagent before - cp in mlsrv.ext.ini See Figure 2. Figure 2 Example: java (- jrepath C:SAPMobilePlatformJDK1.6.031-x64jre - agentlib:yjpagent - cp 8. This completes the configuration of the YourKit and the SUP Server. Yourkit Java Profiler Guru How To Start CollectingIn the next steps I will show you how to start collecting the performance for the CPU, Memory and Garbage collecting. User needs to monitor and collect CPU, Memory and Garbage collecting information. Solution In order to do that, you need to have access to the YourKit as an Administrator. Open YourKit via the desktop icon. You should see in the list of application ini. Figure 3 3. To start collecting double click on the ini. On the menu you will have several option to view. CPU threading as well as memory. Here is a running dialog menu item showing the CPU performance and what is taking place. Figure 4 6. And here for the same CPU process showing the threads that are active. Figure 5 7. In the following screen you can see the additional option to create snapshots for memory. The default location for snapshots is saved C:UseruserprofileSnapshots. YourKit saves the data with a.snapshot format so you would need the YourKit in order to read the files. Figure 6 Figure 7 This completes the collection phase using the YourKit At this point you should have several collection files under your user profiles with the extension.snapshot. In the next section I will show you how to load the files and run the analyzer to extract the information you have collect. Step 2: Reading and analyzing the data that was collected. ![]() Figure 8 2. Point to you use home directory and select one of the snap shot files. Figure 9 Once the file is loaded you can select each option to view such as CPU usage. Figure 10 Figure 11 Note in Figure 12 the message not closed files and Socket connection this is from a test connects from the SAP Control Center. There was no work done except a test connect so this is expected. Figure 12 Here are the side by side screen you will see for the memory pool and usage.This is great way to compare memory usage. Figure 13 If you wish to go even deeper in to the YouKit file there is an option to analyze the file.
