Java 1.4.2 default cache size problems

Hello all -
I am delivering panoramic image Virtual Travel® tours via Flash and the Java PTviewer applet, e.g. http://www.taj-mahal.net
We want to deliver much larger & "full screen" panoramas as well. This all works fine on PCs (sigh), but not on Macs.
On the Mac, I am seeing hanging" during loading of panos, and traced this to the fact that Windows typically has a 60 MB Java cache. I thought this was the same for Mac, but ....
I note that my Java 1.4.2 Plug-In Control Panel shows that only 50 MB is allocated. Since I have not adjusted this, I wonder...
a) Is the default Java cache for Mac OSX set a 50 MB after installation? Would most typical Mac users then have only 50 MB of Java cache?
b) Is there a user-friendly way to adjust the Java cache size up to 60 MB on the Mac? Some application or AppleScript or some such? If so, I can post an error message when (poor) Mac users try to view our large panoramas.
( I want to avoid trying to explain how to find and use the Java Plug-In control panel.... )
Thanks for your help !

Where does that prerequisite come from?
On linux x86, Oracle provides the j2se jdk/jre for OracleAS itself, meaning OracleAS Forms & Reports services 9.0.4 does not require you to install a JDK. I think that actually the requirement is that you should not install any JDK. Of course, some other software might require you to install 1.4.2 java sdk.
You can find the AS 9.0.4 docu libraries here:

(see docu library B13597_05, Platform tab for installation guides)

Is there a solution to Rapidweaver Stacks Cache size problems?

Is there a solution to Rapidweaver Stacks Cache size problems?
My website http://www.optiekvanderlinden.be , has about 100 pages and is about 250MB in size. Every time I open RapidWeaver with the Stacks-plugin, the user/library/cache/com.yourhead.YHStacksKit folder grows to several Gigabytes in size. If I don't manually empty the com.yourhead.YHStacksKit Cache daily, AND empty the Trash before i turn off my mac, my Mac still has problems and stalls at startup the next day. Sometimes up to 5 minutes and more before he really boots. If i have a been working on such a large site for a few weeks without deleting that cache, than my iMac doesn't start up anymore, and the only thing left to do is completely reinstall the iOs operating system. This problem doesn't happen the days i use all my other programs but don't use Rapidweaver.
Does anyone know a solution and / or what is the cause of this?

once more,
i just launched my project in Rapidweaver, and WITHOUT making any changes to my pages, the cache/com.yourhead.YHStacksKit folder filled itself with 132 folders (total 84Mb), most of them containing images of specific pages etc. The largest folder in the cache is the one with the images of a page containing a catalogue of my company, this folder is 7Mb. It seems by just starting up a project, immediately different folders are created containing most of the images in my project, and some folders with a log.txt file. Still i don't see the reason why it is filling op a huge Cache even without making changes to the project. I have 2 different sites, so 2 different projects, and i get this with both of them.

Default cache size reduced to 350 MB (from 1024 MB)

Why was the default size of the automatic cache management reduced from 1024 MB to 350 MB ?
How does that improve Firefox ?

Default artboard size problem

In Illustrator CS2 I am converting CAD files (typically dxf's) to EPS's scaled to fit on an 8.5" x 11" artboard. I generate these files in AutoCAD and lately, the DXF's will open in Illy by default on a 22" x 64" artboard. I use this size occasionally for a different project but I need this artboard size to default to letter portrait instead. I've checked the AutoCAD layout manager and it is also set to letter size. Somehow when either exporting or saving a 22" x 64" file, I managed to force Illy to change it's default artboard size. I have double checked my startup files and the document set up is 8.5" x 11". My page size is also set to letter and I have not edited my PPD file. New AI files still open to my start up file's specifications. I'm guessing this is either a glaringly obvious oversight on my part or a glich. Any ideas? Much appreciated.

Default paper size problems

Recently upgraded to Lion OS X (all software updates installed).
It doesn't seem to matter which application I'm in (outlook, office for mac, firefox, adobe, etc), and how many presets I save and set up - every time I print the application thinks I am printing on US Legal sized paper. But I only have US Letter (as the printer's defaults selections say (in System Preferences)).
It means Every Time I want to print I have to go in and change it to US Letter from US Legal, and if I forget it cuts off the printing making the printing unusable. Is there not somewhere centrally I can save this once and for all??
It also means when I try and print double-sided I get an error message saying: "The Two-sided option, Long-edge binding, is not available when the destination paper size is set to US Legal."
But when I look at the default print settings in System Preferences it clearly says:
Default Printer: HP Officejet Pro 8500 A909a
Defailt paper size: US Letter
- I'm not sure where else to tell the printer that I Do Not Have Any US Legal Sized Paper!
I have an: HP Officejet Pro 8500 All-in-One Printer - A909a.
Can anyone help please?!

Hello Sawest,
Thanks for the post. With this one, the Apple Links were provided for the post above yours. It sounds like either your default printer has been changed in XP or removed, especially since you indicated you lost your ability to scan. As far a re-installation, sound like a good idea based on your description of the printers behavior. Yes, depending on which model of printer that you have and operating system, you can locate drivers that can be downloaded and installed to get you back and running again. Locate your printer model and then go here:
http://www8.hp.com/us/en/support-drivers.html
Plug in you model and go to software and drivers, choose your OS and then you can see what is available for download. I hope this helps, Good Luck!
I worked for HP but my posts and replies are my own....Thank you!

Default Adobe Drive cache size is only 128MB

The Adobe Drive cache size defaults to 128MB. This doesn't seem a very logical value as a single file may be easily larger than that. Is there a reason it's so small? As most users would probably benefit from a larger cache size and today's harddrives should also allow a larger cache size.
Would it make sense to have a default cache size of 5-10GB? Maybe depending on the amount of free disk space available during installation?

Hello.
To help automatically clear up some cache from Firefox, click on each of the images from left to right. Now at least you won't have to constantly do it yourself.
Also, to help you with your space issues, download Clean Master from the Google Play app Store: https://play.google.com/store/apps/details?id=com.cleanmaster.mguard this app will clean up hidden cache and useless files on your phone, helping free up space.
And as for why Firefox keeps reverting to the default cache in "about:config", I do not know. We are sorry for any inconveniences that this has caused you. But please try doing what was mentioned above to help with your issue.
Hope this helps!

Sequence - cache size ?

I created my sequence to increment by 1 with a default cache size of 20. This works fine as long as all my entries are done in the same session ( n + 1, n + 1... and so on). However, when I exit/return to my app the new sequence begins like: Last n + 20, n + 1, n + 1. . . and so on. Is it possible to reduce the cache size of a sequence?

Leo,

Jinitiator Question - JAR Cache Size Location

Using Jinitiator 1.3.1.22 - on Windows 2000 Pro
Does anyone know where this setting is stored on the PC when set in the Java Console? I have looked at the properties121222 in the .jinit folder under the User profile in Docs and Settings and it isn't in there!

Thanks Francois...I know that bit. I want to know where the value for the default is actually derived from for my installation. According to the Forms Services Deployment Guide 'The default cache size for Oracle JInitiator is 20000000. This is set for you when you install Oracle JInitiator.'
If you override the default in the Jini Configuration Panel, it's value will appear in a text file in the users .jini folder. Where is it held before that?!
When Jini is installed at my workplace, the default for the JAR cache is 50mb. No one knows why and how it differs from what the documentation states! This is what I am trying to get to the bottom of!

ADO Recordset Cache Size Breaking SQL Reads

I've got a C++ application that uses ADO/ODBC to talk to various databases using SQL.
In an attempt to optimize performance, we modified the Cache Size parameter on the Recordset object from the default Cache Size of 1 to a slightly larger value. This has worked well for SQL Server and Access databases to increase the performance of our SQL reads.
However, talking to our Oracle 8i (8.1.6 version) database, adjusting the Cache Size causes lost records or lost fields.
We've tried the same operation using a VB application and get similar results, so it's not a C++ only problem.
For the VB app, changing the cursor-type from ForwardOnly to Dynamic does affect the problem, but neither work correctly. With a ForwardOnly cursor the string fields start coming back NULL after N+1 reads, where N is the Cache Size parameter. With a Dynamic cursor, whole records get dropped instead of just string fields: for example with a Cache Size of 5, the 2nd, 3rd, 4th and 5th records are not returned.
In our C++ application, the symptom is always lost string fields, regardless of these two cursor types.
I've tried updating the driver from 8.01.06.00 to the latest 8.01.66.00 (8.1.6.6) but this didn't help.
Is anybody familiar with this problem? know any workarounds?
Thanks

Question of Berkeley DB "cache size"

quote:
Set the size of the shared memory buffer pool, that is, the size of the cache.
The cache should be the size of the normal working data set of the application, with some small amount of additional memory for unusual situations. (Note: the working set is not the same as the number of pages accessed simultaneously, and is usually much larger.)
The default cache size is 256KB, and may not be specified as less than 20KB. Any cache size less than 500MB is automatically increased by 25% to account for buffer pool overhead; cache sizes larger than 500MB are used as specified. The current maximum size of a single cache is 4GB. (All sizes are in powers-of-two, that is, 256KB is 2^18 not 256,000.)
The database environment's cache size may also be set using the environment's DB_CONFIG file. The syntax of the entry in that file is a single line with the string "set_cachesize", one or more whitespace characters, and the cache size specified in three parts: the gigabytes of cache, the additional bytes of cache, and the number of caches, also separated by whitespace characters. For example, "set_cachesize 2 524288000 3" would create a 2.5GB logical cache, split between three physical caches. Because the DB_CONFIG file is read when the database environment is opened, it will silently overrule configuration done before that time.
This method configures a database environment, including all threads of control accessing the database environment, not only the operations performed using a specified Environment handle.
This method may not be called after the environment has been opened. If joining an existing database environment, any information specified to this method will be ignored.
This method may be called at any time during the life of the application.
Parameters:
cacheSize The size of the shared memory buffer pool, that is, the size of the cache.
The question:
When I have a host, the memory total is 16G.
I don't know what mean of this document.
How many max cache size can be set ?
4G? 16G?
or cacheCount (4)* 4G = 16G?
My Email: [email protected]

What version of Berkeley DB are you using?
I'm a little confused about what you are quoting. Most of your quote seems to be from DB_ENV->set_cachesize(), but set_cachesize does not have a parameter named cacheSize. The parameters for set_cachesize are gbytes, bytes and ncache.
You use set_cachesize to specify the logical cache that you can optionally split into more than one physical region. The maximum size of the logical cache is 4GB and there is only one logical cache. You specify the total size of the logical cache with the gbytes and bytes parameters. If you set ncache to a value greater than 1, you split this logical cache into separate physical regions. So, for example, if you specify (gbytes=2, bytes=0, ncache=1) you will have a logical cache of 2GB that internally is split into 2 separate physical regions of 1GB each.
You can read more about the memory pool cache in the Reference Guide sections "Selecting a cache size" and "Configuring the memory pool".
If you have other Berkeley DB questions that are not specific to replication, you should direct them to the general Berkeley DB forum where you will have the benefit of a wider set of Berkeley DB experts:

Trying to change the cache size of FF3.6 from 75meg to a larger size, it only applies on a per session basis. i check the about:config and the changes have applied but when i restart FF it has reset itself to 75 :(

as per the question, tried to up the cache from 75meg to 300meg but it resets after i restart firefox, have tried to change to various cache sizes but to no avail.
-=EDIT=-
it must be something to do with the profile, as when i set up a new profile in the manager, the cache size problem no longer appears. but now, how to repair my profile

ok, nothing in that text file helped but the original file that it was based on pointed me in the direction that it might be an extension. The only extensions i have are NoScript and FasterFox Lite version....
I have now traced the fault to lie with FasterFox... if you are not familiar with fasterfox it speeds up internet connections in firefox... several of the options are presets... but when i selected custom it gave me the option of a cache setting, which was set to 75megs.
I have now changed that cache setting in fasterfox to 300 Megs and it is now persistant in firefox on restart.
hopefully this information will be helpful to other people in the future that suffer the same problem.
Thanks for your help TonyE, its greatly appreciated

Dynamic Calc processor cannot lock more than [100] ESM blocks during the calculation, please increase CalcLockBlock setting and then retry(a small data cache setting could also cause this problem, please check the data cache size setting).

Hi,
Our Environment is Essbase 11.1.2.2 and working on Essbase EAS and Shared Services components.One of our user tried to run the Cal Script of one Application and faced this error.
Dynamic Calc processor cannot lock more than [100] ESM blocks during the calculation, please increase CalcLockBlock setting and then retry(a small data cache setting could also cause this problem, please check the data cache size setting).
I have done some Google and found that we need to add something in Essbase.cfg file like below.
1012704 Dynamic Calc processor cannot lock more than number ESM blocks during the calculation, please increase CalcLockBlock setting and then retry (a small data cache setting could also cause this problem, please check the data cache size setting).
Possible Problems
Analytic Services could not lock enough blocks to perform the calculation.
Possible Solutions
Increase the number of blocks that Analytic Services can allocate for a calculation:
Set the maximum number of blocks that Analytic Services can allocate to at least 500.
If you do not have an $ARBORPATH/bin/essbase.cfg file on the server computer, create one using a text editor.
In the essbase.cfg file on the server computer, set CALCLOCKBLOCKHIGH to 500.
Stop and restart Analytic Server.
Add the SET LOCKBLOCK HIGH command to the beginning of the calculation script.
Set the data cache large enough to hold all the blocks specified in the CALCLOCKBLOCKHIGH setting.
Determine the block size.
Set the data catche size.
Actually in our Server Config file(essbase.cfg) we dont have below data added.
CalcLockBlockHigh 2000
CalcLockBlockDefault 200
CalcLockBlocklow 50
So my doubt is if we edit the Essbase.cfg file and add the above settings and restart the services will it work? and if so why should we change the Server config file if the problem is with one application Cal Script. Please guide me how to proceed.
Regards,
Naveen

Your calculation needs to hold more blocks in memory than your current set up allows.
From the docs (quoting so I don't have to write it, not to be a smarta***:
CALCLOCKBLOCK specifies the number of blocks that can be fixed at each level of the SET LOCKBLOCK HIGH | DEFAULT | LOW calculation script command.
When a block is calculated, Essbase fixes (gets addressability to) the block along with the blocks containing its children. Essbase calculates the block and then releases it along with the blocks containing its children. By default, Essbase allows up to 100 blocks to be fixed concurrently when calculating a block. This is sufficient for most database calculations. However, you may want to set a number higher than 100 if you are consolidating very large numbers of children in a formula calculation. This ensures that Essbase can fix all the required blocks when calculating a data block and that performance will not be impaired.
Example
If the essbase.cfg file contains the following settings:
CALCLOCKBLOCKHIGH 500 CALCLOCKBLOCKDEFAULT 200 CALCLOCKBLOCKLOW 50
then you can use the following SET LOCKBLOCK setting commands in a calculation script:
SET LOCKBLOCK HIGH;
means that Essbase can fix up to 500 data blocks when calculating one block.
Support doc is saying to change your config file so those settings can be made available for any calc script to use.
On a side note, if this was working previously and now isn't then it is worth investigating if this is simply due to standard growth or a recent change that has made an unexpected significant impact.

Change the default stack size in the java.exe file

Does anyone know how to change the default stack size of the jvm?
I'm having problems with my stack. Is there anyway I can change it. I found a tool editbin.exe which is shipped with Visual c++, however I don't have the tool.
Thanks,

I am using JNI to connect java with a C++ application.
When calling the C++ appliction, STACK_OVERFLOW
happends. I tried java -Xss<size> to increase the
stack size, but failed.This has nothing to do with the above question.
Does anyone knows why?Probably because the java parameter specifies the java stack size and not the C++ stack size.

Java.sql.SQLException: Statement cache size has not been set

All,
I am trying to create a light weight SQL Layer.It uses JDBC to connect to the database via weblogic. When my application tries to connect to the database using JDBC alone (outside of weblogic) everything works fine. But when the application tries to go via weblogic I am able to run the Statement objects successfully but when I try to run PreparedStatements I get the following error:
java.sql.SQLException: Statement cache size has not been set

i have checked the StatementCacheSize and it is 10. Is there any other setting that needs to be implemented for this to work? Has anybody seen this error before? Any help will be greatly appreciated.
Thanks.

What is the best way to verify default heap size in Java

Hi All,
What is the best way to verify default heap size in Java ? does it vary over JVM to JVM . I was reading this article http://javarevisited.blogspot.sg/2011/05/java-heap-space-memory-size-jvm.html , and it says default size is 128 MB but When I run following code :
public static void main(String args[]) {
int MB = 1024*1024;
System.out.println(Runtime.getRuntime().totalMemory()/MB);
It print "870" i.e. 870 MB.
I am bit confused, what is the best way to verify default heap size in any JVM ?

Hi Kayaman,
Sorry but I don't agree with you on verification part, Why not I can verify it ? to me default means value when I don't specify -Xms and -Xmx and by the way I was testing that program on 32 bit JRE 1.6 on Windows. I am also curious significant difference between 128MB and 870MB I saw, do you see anything obviously wrong ?That spec is outdated. Since Java 6 update 18 (Sun/Oracle implementation) the default maximum heap space is calculated based on total memory availability, but never more than 1GB on 32 bits JVMs / client VMs. On a 64 bits server VM the default can go as high as 32gb.
The best way to verify ANYTHING is to address multiple sources of information and especially those produced by the source, not some page you find on the big bad internet. Even wikipedia is a whole lot better than any random internet site IMO. That's common sense, I can't believe you put much thought into it that you have to ask in a forum.
