Optional Package - does it decrease memory size for war

We have around 10+ war files running within WLS 10.3.4.
Each of the war files are around 40 megs each.
I am looking at building a frameworks jar (via Apache Shade) and make that jar an optional package (which includes all my 3rd party frameworks like Spring/CXF/etc).
By deploying this jar as an optional package, I can cut the size of the war file in half.
The question is, does this really save the size of the war in memory?
When I deploy a war with a reference to an optional package, does WLS explode the war, import the optional package, and rebuild the war for deployment so that in the end, it equates to the same size war as if I had never utilized the optional package? The documentation seems to allude to this.
I want to know (before I do all the work), if decreasing the size of the war by excluding 3rd party libraries into an optional package will actually reduce the size of memory for each war.
Thanks,
Jay

One option is: use the c6/c7/c8 parameters if the INSTALL APDU. Start with a high value and work your way down. That will tell you how much mem you have.
The other option is to load an applet that allocates a large byte array. Work your way down and when it can successfuly allocate the memory, that's whats available on the card for you to use.
Third option: Get a 2.2 card and just call the API ! ! !

How do I determine the size of an event (cmd I does not show any size for events).

How do I determine the size of an Event in iPhoto? (Cmd + I does not show size information at the event level).

If you're running iPhoto 8 (09) select the event and look at the Info pane at the lower left hand corner of the window. It will give you the number of photos and size:
for iPhoto 9 (11) open the Event, select all of the photos in it and open the Info drawer at the right by typing Command+i. The number of photos and size will be at the top of the Info drawer.

Is it possible to config memory size for a process?

Dear experts,
I would like to control the memory size assigned for a process on Solaris 9. Can i config memory size assigned for process??
Many thanks,
Shun

You can use ulimit/limit to assign a bound on the amount of space that a process and its children can allocate.
I'm not sure if that's what you're asking though.

How to change heap memory size for general java applications (not applets)

Hi. I made a java class which manipulates images and I sometimes get an out of memory error when the files are large. In these cases I can run it successfully from the command line using:
java -Xms32m -Xmx128m myappbut as I run this class from a firefox extension, I can't use this technique.
Could some one tell me how to set this globally? I've found a lot of info on setting it for applets in the control panel but that's it. I also tried editing my deployment.properties file by adding:
deployment.javapi.jre.1.6.0_11-b03.args=-Xmx128mbut none of these options seem to work.
Thanks for any help.

Also you can use use [JAVA_TOOL_OPTIONS|http://java.sun.com/j2se/1.5.0/docs/guide/jvmti/jvmti.html#tooloptions], with more documentation here. JAVA_TOOLS_OPTIONS is available since 1.5. There is no direct documentation on [_JAVA_OPTIONS|http://java.sun.com/j2se/1.5.0/docs/guide/2d/flags.html] but was made available since at least 1.3.
The recent existing forum thread [Java Programming - How to change the default memory limits for java.|http://forums.sun.com/thread.jspa?threadID=5368323&messageID=10615245&start=36] has a long discussion on the issue.
You specified you are not using applets, but if you do, I would also suggest you use the next Generation Plug-in (since 1.6.0_10) that allows you specify the max memory in the applet without having to instruct the user how to make the change. See [JAVA_ARGUMENTS|https://jdk6.dev.java.net/plugin2/#JAVA_ARGUMENTS] for applets. Java Webstart uses resources.

Find heap memory Size for Web Intelligence processing server in BO 4.0

Hi All ,
We need to gather data for sizing inputs.For Adaptive processing server , we can find same by going in CMC> Server > APS > Properties & check value for the parameter -Xmx . Could you please tell how to find the max heap memory allocated for a Web Intelligence processing server in BO 4.0 as for Webi server this parameter is not maintained. ?
Regards ,
Abhinav

Hi Abhinav,
The maximum threshold is a value which may reach on peak usage and Webi processing server cannot occupy memory beyond this value at any time.
In your situation 9 Webi Processing servers with 16 GB of RAM on server is not recommended. This is because consider situation with total 16 GB of host RAM.
4 GB should left for OS
Tomcat will need minimum 2 GB for 200 users
So you are left with 10 GB RAM for all BO services
Now 9 Webi Processing servers with 6 GB of Threshhost will not work here
For this configuration you can have 2 Webi Processing servers with default threshold should be running on single host.

Hrishikesh

How to set memory size for JRE

hi all,
Is there anyone know how to set the JRE memory size?
My run my applet application onto browser and I want to increase to size of memory. Such as -ms 128m -mx256m.
please help.
regards,
elvis

The suggestion could be convert applet into WebStart application which is quite similar to applet (at least
it is distributed similar way, resides within sandbox etc) but allows to specify memory size as you requested.

I cannot update ipad1 iOS 4.2.1 to a newer version. There is no Point in options. Does anyone have an answer for this?

...

If you have an iPad 1, the max iOS is 5.1.1. For newer iPads, the current iOS is 6.1. The Settings>General>Software Update only appears if you have iOS 5.0 or higher currently installed.

If you are currently running an iOS lower than 5.0, connect the iPad to the computer, open iTunes. Then select the iPad under the Devices heading on the left, click on the Summary tab and then click on Check for Update.
Tip - If connected to your computer, you may need to disable your firewall and anitvirus software temporarily. Then download and install the iOS update. Be sure and backup your iPad before the iOS update. After you update an iPad (except iPad 1) to iOS 6.x, the next update can be installed via wifi (i.e., not connected to your computer).

Is there a problem with maximum RAM size for Satellite 320CDT?

I have a Satellite 320CDT with the latest BIOS (v8.00) and Windows 98 SE installed; there is 32MB base memory and a 32MB module in the single expansion slot. If I change this for a 64MB expansion module I can still only see 64MB total memory reported, not 96MB as expected; the spec for the machine states that the maximum allowable memory is 160MB (32MB base + 128MB expansion). Does anybody know if there is a problem with the maximum memory size for this model and whether there is a solution or workaround? I need to know quickly, in order to decide if I need to return the memory module to the supplier! Many thanks for any help, Peter

Are you certain you tried the correct type of memory module? It sounds like you're maybe trying to fit an incompatible type.
There's a few different suppliers below.

[Athlon64] K8MM-V - Memory Size

Hi,
I have a K8MM-V with a AMD Samperon 64bit (3000+) CPU and am wondering about the max memory size for it.
The website says that it handles 2GB of DDR400. I have 2x1GB DDR400 chips and the BIOS only sees 1.5GB as does Windows.
The memory have Samsung chips and are of the same time. What is wrong? Or did I not set something correctly?
Bios is at ver1.3. The memory is set to AUTO. So I am not sure what is going on

Memory banks, You know you can get double sided memory modules.
So if you installed a double sided module you could not use dimm slot 2.
Each dimm slot has 2 memory address lines so you can access both sides at the same time and use double sided modules.
So
dimm slot 1 = bank 0 and Bank 1
dimm slot 2 = bank 2 and Bank 3
dimm slot 3 = bank 4 and Bank 5
Since there are over hundreds types of memory modules and they are using different type of DRAMs to build them, it is very possible that you have purchased a (cheap) memory module which is not compatible with your computer.
For example, there might be 3-4 different types of 128MB memory modules and some computers are very picky and can only support 1 type or 2 types of 128MB memory modules. If it is incompatible, then usually you will not be able to boot up your system or you will see frozen screen or system might only recognize half of the memory size. This issue adresses to very low compatibility, because memory maker use several configuration.
Maybe you can try setting memory to "SPD"
Edit here: try using only one stick at a time, if they are reconized alone as 1 GB the problem will remain in the very low compatibility issue, and maybe you want to buy some others ram stick from another chip maker, maybe Geil, or Corsair.

Epson Print CD - "Increase memory size"

Bit of a long shot I guess, but I'm trying to print onto a CD using Epson Print CD... However, when I go to print, it comes up with a message that says "Please increase memory size for print CD", and won't go any further. I'm guessing that has something to do with setting preferences in OSX, but I have no idea what to do...
Any ideas?

Greg,
Actually the versions are newer. I just visited the Epson website and found this info. Thank you for the pointer.
Here's the PowerPC version for your iMac iSight 2.5aAas for 10.2 to 10.4, and Intel version, if you got any Intel Macs 3.0aAs for 10.4.4 and above on the U.S. website. The U.K. links for the same printer are here: PowerPC version 2.5, and Intel version 3.0. Not sure if there is a difference, but you might want to try the U.S. version of the drivers.

How does one change the font size for folders and/or file lists in the Bookmarks Library?

How does one change the font size for folders and/or file lists in the '''Bookmarks''' Library?
Since the upgrade to version 9.0.1 of Firefox, the Bookmarks feature changes are confusing me. They seem to be confusing themselves as well. The list of bookmarks has changed. The font size is so small that my aging eyes cannot read it without fogging the screen with my breath. Some folders are out of alphabetical order (where I know they were previously good), and some are missing altogether (folders to which I frequently add references).
As for missing or deranged files or folders, was there something that I should have done or now need to do to recover those after the upgrade (or before)?
With regard to font size,
1. there is no “Edit Bookmarks” or like option to edit the list in this version
2. the “zoom” option in the “view” list of functions is greyed out when in “Show All Bookmarks” window
3. expanding the browser window has no effect on font size
4. “Preferences” settings for font size has no effect in that window either, including advanced settings
5. “Help” offers none that I can find.
Can any of you Help?!?

Maybe this extension helps:

Open iPhoto, select a couple of photos and use the Share ➙ iWeb ➙ Photo page menu option. That has jump started iWeb for others. I could take a couple of tries.
If that doesn't work try the following:
1 - delete the iWeb preference file, com.apple.iiWeb.plist, that resides in your

2 - delete iWeb's cache file, Cache.db, that is located in your

Maximum package size for data packages was exceeded and Process terminated

Hello Guru,

Thanks & Regards,

Hi,
When the load is not getiing processed due to huge volume of data, or more number of records per data packet, Please try the below option.
1) Reduce the IDOC size to 8000 and number of data packets per IDOC as 10. This can be done in info package settings.
2) Run the load only to PSA.
3) Once the load is succesfull , then push the data to targets.
In this way you can overcome this issue.
You can also try RSCUSTV* where * is an integer to change data load settings.
Change Datapackage size for extraction, use Transaction RSCUSTV6.
Change Datapackage size when upload from an R/3 system, set this value in R/3 Customizing (SBIW -> General settings -> Control parameters for data transfer).
IN R/3, T-Code SBIW --> Genaral settings --> Maintain Control Parameters for Data Transfer (source system specific)
Hope this helps.
Thanks,

Restart deployment (.ear) does not load optional package

Hello everybody,
In our 10.3.5 WLS domains, we are using optional packages for sharing libraries between applications see [http://docs.oracle.com/cd/E24329_01/web.1211/e24368/libraries.htm|Creating Shared Java EE Libraries and Optional Packages]
The problem is that if I redeploy the library I have to redeploy the deployment. This issue only happens with the applications packaged as *.ear*. If the application has been deployed as a .war, with restarting the deployment is enough.
Would be possible to load the referenced library from an *.ear* just restarting the deployment?
Thanks in advance,
Luis
