Want to increase Java Heap Size to 4GB+: Physical Memory 8 GB, JVM 64-bit -

-

I want to run a memory intensive package on a web server.

The settings of the current computer are. Windows 7 64 bit 64-bit JVM RAM: 8 GB

When I run EXPLUS CO-XMS 1024 M-XMX 2048 M -XX: I try: Maxim Sylez = 256m

I am getting:

An error occurred during the initialization of the VM, enough space could not be reserved for the object pile, the Java Virtual Machine Could make

The post I read, it seems that I should be able to use more than 4GB when I ran the code of memory, then I was able to exclude memory at max-Xmx1200M And still be able to run the code. But what I want to accomplish, I need to use more memory. How can I increase memory size here?

Thank you all for the issue that I was using the 32-bit version of JDK. After switching JDK to 64 bit version, I was able to run the memory in 2 GB. Thanks!

The problem was that I was using the 32-bit version of JDK.

Thank you, and thank you for telling Mr Smith that I should answer this and solve it.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

Oh, for the moment I am not sure how it is officially supported, but for the success of the people Using Monodroid Vic Cool Storage I am able to leave and compile assemblies in my project, but while trying to use some classes, the errors of time have to be gathered. Especially when trying to connect like the example for Mono Touch string dbName = path. Cobain (environment.

python - referencing a variable in another function? -

-
I am an experienced TCL developer and write my own processes to help myself. I call it a proc i callVar, print out the value of the variable in a certain format, so I know that it is variable and what is the value "set foo 1; putVar foo" result 'foo = "1" I want to do the same thing in Python, but I can not find the answer :( In TCL I use the up command because when I pass the name of the variable, then I can see the value at the top. . I understand that an advanced light in the dragon There is no mechanism of r, but with its introspection capability, I would think that this is something trivial, but I am not getting the answer anywhere. It seems that this should work: and expanded: def foo (): y = "Hello World" printwor ("y") foo () y = "Hello World " You can, but you should not do so if your code is correct If is needed , then there is something wrong with your design, and you should probably use the dictionar...
