What do I do if I get a Java™ out-of-memory error?

HANDLE.NET FAQs
If you get an out-of-memory error (or would like to increase the amount of memory that the server can use), add the "-mx128m" argument when running java/jre. In fact, we recommend increasing the amount of memory available to Java to allow Java and the server to use up to 128 megabytes of virtual memory, if necessary. Alternatively, the config.dct file can be edited to cut down on the amount of memory used by changing the number of threads allocated for each listener.

What size is a .NET object?

Andy Mc's .NET Framework FAQ
Each instance of a reference type has two fields maintained by the runtime - a method table pointer and a sync block. These are 4 bytes each on a 32-bit system, making a total of 8 bytes per object overhead. Obviously the instance data for the type must be added to this to get the overall size of the object. So, for example, instances of the following class are 12 bytes each: class MyInt { ..

Object concepts Q: What's the difference between a class and an object in Java?

Code Style: Java objects frequently asked questions (FAQ)
A Java class is a definition or model of an object type. A class has a specific set of fields, methods and constructors with distinct argument types. Any object that fulfils a class definition directly or by inheritance has a set of properties and behaviour that is common to all instances of the class. In this sense, a class is like a set of things that are alike. In Java concrete classes also provide a code implementation that can be instantiated to create an object reference.

I am getting a memory allocation error. Why?

Answers to Questions
If you can access your security features, verify that you have them set the way you want them. If you cannot access the security features, go into Unibase\misc and delete etpasswd file. You will then have to recreate your security features.

How do you handle error messages, memory allocation, etc.?

Visual Kinematics - Products
All detected errors are reported through a single error handler function. All memory allocation is performed with three functions which most of our clients override so that they can detect any memory allocation failures and recover. As component software, our products must exist dutifully in the host application - nowhere do we "exit", "assert", "printf", etc.

D.1.5] What is the best memory allocation for Bringer?

Winboard and Chess engines : Section D - Engine Specific Pro...
For 16Mb RAM , the author suggests using 10/2/2 [Position/Evaluation/Pawn] allocation and another 2 Mb for Tablebases caches. For allocating 32 Mb RAM a 20/4/4 Split might be best. You could also try optimising the memory allocation yourself, but this requires some understanding and monitoring of the line "Hash% Pos: 1%/5%, Eval 53%/16%, pawn 99%/80%" etc in the program.

Q Why does registration and set up fee increase with memory size?

FAQ's & Terms
This is to reflect the initial costs of providing and preparing the capacity. The annual fees are only for maintenance and operation.

I have my own memory allocation scheme. Can I still use Memory Advisor?

Frequently Asked Questions
Memory Advisor performs dynamic allocation error detection only on memory areas returned by malloc(), calloc(), and realloc(). If you have based your own allocation scheme on these functions, you have Memory Advisor's full error detection capabilities. On the other hand, if your routines call sbrk() and manage the memory themselves, Memory Advisor does not check accesses to those areas. The use of sbrk() may cause problems of which we are not aware.

Can the object move?

In Nomine Frequently Asked Questions - Celestials
Also depends on the object. Anything designed to bend or move will be able to do so. So a door could open and close, a car could drive around, a ball could roll, a puppet could walk around. But a candlestick couldn't move around on its own, since it is inflexible. Neither could a hammer lift itself to hammer a nail (or whatever). Certain Songs can give movement abilities, however. For example, Numious Corpus: Wings and that toaster vessel . . .

Are there any limits on the size of a serialized object?

jGuru: Serialization FAQ Home Page
There are limits, but in practice you shouldn't encounter them. You are limited by the amount of memory your JVM can allocate to the creation and maintainence...

How can I recall one object from a memory archive?

HP48 Frequently Asked Questions List (FAQ): Questions about ...
There is a little-known method of recalling objects from within archives. Just make a list representing the PATH to the object, and tag the list with the port number. Then hit RCL or EVAL.

D.1.4] How do I change the Transposition Table memory allocation for Bringer?

Winboard and Chess engines : Section D - Engine Specific Pro...
Unlike most Engines, there is no ini file to edit to change the size of the transposition tables. You need to do it in the Bringer GUI and then save.

Will we ever get Java?

Answers to Some Frequent webtv.users Questions
According to posts in webtv.users from Steve Perlman, ex-president of WebTV, WebTV has been working to provide a form of Personal Java for the WebTV Plus terminal (and possibly the new Classics and Dishplayer, but nothing was said specifically about them as they were not announced products at the time of the posts)?there is no guarantee this will happen.

Q: What is Highway Allocation money and how is it determined?

City of Hastings-Engineering Department
Highway Allocation Fund monies are the funds distributed by the State of Nebraska from the collection of Gas Tax collected on motor fuel at the pump. Funds are distributed by a formula established by the State that utilizes population size and lane miles of streets in the formula for distribution. As our community grows in population and increases its street inventory in lane miles, our allocation factor increases.

Q: What is the underlying principle of the allocation Formula?

NHSSCOTLAND RESOURCE ALLOCATION COMMITTEE - Scotland's Healt...
The main objective of the Arbuthnott Formula is to provide for equity of access to healthcare. Resources are distributed among NHS Boards on the basis of relative need for health care services within that population group, where use of services has been used as a proxy for need. Scotland uses an indirect approach to measure healthcare needs.

How can I specify the amount of memory to be used by Java?

Frequently Asked Questions (v0.7)
There are two ways to control this. If you get an OutOfMemoryError when Cocoon is generating pages, see the first paragraph. If you get an OutOfMemoryError when outside of Cocoon (e.g., copying raw files), see the second paragraph. The maxmemory property in the forrest.properties file controls how much memory Cocoon uses. Like many other properties you can copy them from the default configuration at src/core/fresh-site/forrest.

How do I increase the memory for the Java Virtual Machine?

SQL Developer - FAQ
Usually the default memory configuration of your VM should be sufficient to work with SQL Developer. If you want to increase the available memoy anyway you will have to start the application with additional command line options. If you use a Sun Microsystem Java VM open a shell window, change to the SQL Developer folder and type java -Xmx256m -jar sqldeveloper.jar to start with a maximum heap memory of 256 MB. The default maximum heap size is 64 MB.
