If you forget to do this, as a one off when you start SongKong for the first time after installation you can Run as Administrator and this will allow SongKong to delete the files no longer required from the installation.Īlso the executables have changed, we used to haveĬ:/Program Files/Jthink/SongKong/Songkong64.batĬ:/Program Files/Jthink/SongKong/Songkong64.exeĪnd these were added to the Windows Start menu under SĬ:/Program Files/Jthink/SongKong/SongKong.exeĬ:/Program Files/Jthink/SongKong/SongKongGui.exeĬ:/Program Files/Jthink/SongKong/SongKongRemote.exeĪnd these were added to the Windows Start menu under Jthink, this is the same location as the latest release of Jaikoz so useful if you have both applications So before installing new version it is best to simply delete C:/Program Files/Jthink/SongKong to remove the old installation, do this rather than trying to uninstall which does not work reliably (don’t worry this will not remove your settings or license because these are stored under C:\Users*username\AppData\Roaming\SongKong* ) 1.7K Training / Learning / Certification.165.3K Java EE (Java Enterprise Edition).ħ.9K Oracle Database Express Edition (XE).3.8K Java and JavaScript in the Database.With the release of SongKong 6.10 we now use a completely new installer for Windows, this is provided by Oracle (the makers of Java) and provides a much better integration with Windows, making it easier to install and uninstall SongKong.īut it has an different folder structure to the previous Izpack installer, So although it still installs to C:/Program Files/Jthink/SongKong it doesnt overwrite the existing files from previous install, and they cannot be removed by SongKong itself because administrator permission is required to delete them and this is only available when installing Upping the heap space will of course give you more memory to play with, but there are a few reasons why you might not want that to be your full solution:Ģ. if you need to start loading more or larger images/media files then you're just fighting fires if you up it to something which approaches the machine's available Ram and/or there are a number of other applications running, you'll find that it results in paging memory to disk - your application will still work but it will be dog slow and horrible to useģ. You can employ some tactics to economise on memory usage. Each Java process has a pid, which you first need to find with the jps command. SongChanges section of Report running out of memory on large folder contaning all files 02.53.34:MDT:SongCache:findCoverImageByDataKey:SEVERE: Java heap space java. You should take a look at your application and ask yourself these questions:ġ. Once you have the pid, you can use jstat -gc insert-pid-here to find statistics of the behavior of the garbage collected heap. jstat -gccapacity insert-pid-here will present information about memory pool generation and space capabilities. ![]() do you really need all these things in memory at once?Ģ. are you storing files in memory in their compressed (ie file format) form as well as their uncompressed (eg Java Image) formģ. PermGen Memory: This is a special space in java heap which is separated from the main memory where all the static content is stored in this section. can you resample any images smaller and throw away the larger ones?Ĥ. Apart from that, this memory also stores the application metadata required by the JVM. Metadata is a data which is used to describe the data. What you see from the Operating System perspective is the ‘process’ memory which ‘includes’ heap. The Java heap is the area of memory used to store objects instantiated by applications running on the JVM. If you aren't using all the files all the time, you may well benefit from using a cache based on SoftReferences (see here for a bit about reference objects - ) -properly implemented, this will allow you to keep some temporarily unused objects kicking about unless the GC "needs" the space. When the JVM is started, heap memory is created and any objects in the heap can be shared between threads as long as the application is running. ![]() ![]() The size of the heap can vary, so many users restrict the Java heap size to 2-8 GB in order to. No, Java already cleans up its own heap space. ![]() Sadly, Sun's VM interprets that "need" rather oddly and seems very eager to clear soft references when there's no need to do so, so I ended up having to put in a cute little trick to stop them getting unnecessarily wiped. Its called 'garbage collection' and it happens automatically. If you run out of memory (which is what I gather from your vague paraphrase of the problem) then you either need to allocate more memory for the Java runtime, or modify your Java code to use less memory.
