Process and Memory Board

Noting that the MP 09 has a removable "processor and memory board", one sees the potential for easier warranty repair by swapping out a new board for an old one, I would assume.
Does any one see other potential in the ability to swap out the processor board and memory component?

Spawned Processes and Memory

Hi Guys,
Does the JVM limit the amount of memory that a process uses when spawning using Runtime.exec()
Basically we are trying to run the microsoft linker from Java (via Maven) and it keeps erroring with 'out of memory' this seems to happen when the process uses around 275MB of RAM.
Are processes spawned by Java limited to the amount of memory allocated to the JVM via -Xmx ?
Any insight on this matter would be appreciated.

Check the source code of the function
Java_java_lang_Win32Process_create
in j2se\src\windows\native\java\lang\Win32Process_md.c (you can get such
source code downloading the SCSL Source code.
The relevant information is posted below.
    si.dwFlags = STARTF_USESTDHANDLES;
    processFlag = CREATE_NO_WINDOW;
    ret = CreateProcess(0,                /* executable name */
                        cmd,              /* command line */
                        0,                /* process security attribute */
                        0,                /* thread security attribute */
                        TRUE,             /* inherits system handles */
                        processFlag,      /* selected based on exe type */
                        envcmd,           /* environment block */
                        cwd,              /* change to the new current directory */
                        &si,              /* (in) startup information */
                        &pi);             /* (out) process information */It simply does not adjust memory size, or do something mysterious. It simply creates the process, and redirects the input , output and error streams.
You really must get more memory (or adjust the size of your Windows swap file)...
You can try lowering (not raising) the -Xmx limit of your Java program to make more room for the "link" process.

XSLT processing and Memory Leak

I have the following code for a Simple XSLT Transformation from one form of XML to another, the Size of the XML and the XSLT file are very small( few KB).
As you can see I'm explicitly setting everything to null just to make sure the objects get GC'd.
When I run the transformation on my local m/c running Windows XP on WSAD5.0 there are no memory leak issues, but when I deploy the Same app on our Server running WSAD 5.1 on Solaris, I see memory issues and finally throws an OutOfMemory Exception.
Any Ideas would be appreciated.

All code work's as well, but i have a memory leak by using structure (by creating a new MyStructure());Presumably this really is java code. As such the following are the only possibilities
1. You do not have a memory leak. You are misreading a tool (probably task manager) and assuming a leak exists when it doesn't.
2. You need to call something either on MyStructure or by passing it to another class to free it. See the documentation.
3. The leak is caused by something else.

Mds process shoots up CPU and Memory

I upgraded to OS X Mavericks about a month ago and ever since, have had to disable Spotlight due to shooting CPU and Memory. The only way to get my Mac to a usable state is to add Macintosh HD to Spotlight privacy list to prevent indexing. The moment I do that, CPU and Memory get to normal.
Here is what Memory/CPU looks when I am doing nothing on my Mac and all apps are closed:

Launching Mail becomes a runaway process and creates a massive memory leak in the kernel task

I have 16gig of ram, my kernel task is currently using 12gig, Mail is no longer responding while using all remaining ram
Mail has been jammed at 100% of one i7 core for about 2 hours now, disk activity is almost nonexistant.
it was running poorly yesterday, rebuilding the mailboxes did not yeild a positive effect
permissions and drive check out
Quicklook is also reporting a lot of bs when finder windows are open:
example:
10/26/13 1:40:20.985 PM quicklookd[14056]: Warning: Cache image returned by the server has size range covering all valid image sizes. Binding: VariantBinding [0x603] flags: 0x8 binding: FileInfoBinding [0x503] - extension: mp3, UTI: public.mp3, fileType: ???? request size:32 scale: 1
I hate the new activity monitor so much, none the less, "Memory Pressure" is pinned
Seeing a whole lot of this in the console as well:

I feel your pain!
Mac Pro with 32 GB, and Mail takes about 5 minutes to "start" - well, show the Mail Menu. Then, another few minutes to actually draw the window... but wait, it STILL needs more time to actually show the accounts and mail.
The (stupid) new Activity Monitor show Mail using 12 GB of RAM, and several com plist files also sucking up CPU time and RAM. Why Apple has to dumb-down good information to "Memory Pressure" is beyond me!
I have reported thsi to Apple, and they had a Support person get in touch with me. I have sent several spindumps and tarball files last week, but no reply. Today, I pinged the support person who said Apple Engineering was reviewing the information, and would likely get back sometime as *maybe* some others were experiencing this problem...

After closing Firefox to use IE8 or any other program (like InterVideo to watch a DVD), everything is very choppy and slow. I have to go into Taskbar, Processes, and close firefox.exe manually (which is using up all the memory/CPU and should have closed before). Then, and only then, does everything behave normally. What is going on and what am I doing wrong or missing??

Powermac flashing status light error and adding memory boards

I bought a used Powermac G5. So far it won't boot, there is no image being delivered to the monitor, and the fan revs like a vacuum cleaner. At first the status light gave series of 3 flashing lights which the online manual (I don't have the specific manual for this machine) says is incorrect memory board or similar message. However, last time I turned on the Powermac the status light now gives single flashes which diagnostic meaning is not even mentioned in the online manual I am using. Does anyone know what single flashes mean? As far as the memory boards are concerned, what is in there now are: Apple memory module M9296G/A (Samsung PC3200U 30331 0413 256MB DDR CL3) in both inner slots, and Hynix PC3200U 30330 0411 256MB DDR 400Mhz CL3 in both second to inner slots. Are these the correct boards? I have on hand 2 other boards from a broken iMac G5. They are Edge Tech 1GB 5380601-40. Can these iMac boards be added to what is in the Powermac or substituted for two of the existing matched boards if they are the wrong type for the Powermac? Both the Powermac and the iMac run Leopard OS. I have also ordered a new battery for the Powermac. The existing battery is dead. Could that cause flashing status light? Thanks.

Better utilization of cpus and memory - Concurrent processing tier

I have a three node 11.5.10.2 setup:
Node1 - Database only (10.1.0.5)
Node2 - Admin, Forms, Web
Node3 - Concurrent processing
My concurrent processing node has lot of free cpus and memory
Cpus: Average utilization 20%
Memory : Average utilization 15%
The highest spikes I've had are:
Cpus- 24% utilization
Memory - 20% utilization
What I can do on the concurrent processing tier that would make better use of the cpus/memory resources and improve performance?
I have 2 dual core Intel(R) Xeon(R) processors and 16 GB Physical memory on the concurrent processing server.
Thanks & regards,

Hi Asif,
You are seeing a manifestation of the old myth from the earlier part of this decade that you need many middle tier servers to effectively interact with users in a busy ERP environment. In reality, the middle tier processes which are normally web, forms, and concurrent managers typically consume only memory, and maybe10-20 percent CPU utilization of a modern quad core Xeon/Opteron Linux server. I have seen several 200 plus user single node 11i installations that handled the load just fine. In my experience, 95-97% of the ERP CPU utilization comes from database sessions, not from middle tier processes. Occasionally, a forms session goes to a runaway, or a ar60run process runs at 100% CPU while the request is running, but if you follow the Oracle recommendations of limiting fnd_concurrent_requests to 50k rows or less, you will not see much CPU utilization from FNDLIBR processes.
Most 32 GB 2 socket quad core servers can support 200 plus forms user connections plus host the concurrent manager as well. I would only add additional web/forms nodes after you start paging on the middle tier box. Having concurrent managers separated on a 10-20 percent utilized server is sort of a waste of a server.
Regards,
-Michael

SCCM 2007 and Active Directory - On-boarding and Off-Boarding Process

Currently, when a user resigns from our company, we rebuild their computer immediately and provide to another user.
From a best practice perspective, should we delete the computername from AD and then rebuild and join to the Domain? We also have SCCM 2007 in place. Are there other best practices for SCCM 2007 and AD that we should be following for on-boarding
and off-boarding users? Any suggestions would be greatly appreciated. :-)

With respect to AD, it will be better to reset the account rather than deleting it. This way the SID is retained and all permissions (for DNS records etc) and AD group memberships will be retained. AD group memberships will be more significant, depending
on whether it is used for SCCM collection definition rules
In SCCM, if the record is not deleted, it will be identified as a known computer and OSD advertisement can be pushed on the client. Ideally task sequence should use same name as the SCCM resource record for naming the newly built computer. In case AD/SCCM
objects are deleted, duplicate records may get created depending on the timing of client registration and AD system discovery cycle. If SCCM client gets installed and registered before next AD system discovery cycle, there shouldn't be any issues.
But if AD discovery cycle runs before client registration, two records will show up in SCCM console and one will be obselete, which has to be deleted manually. This issue can be resolved by adjusting the frequency and schedule of AD system discovery cycle.
My suggestion will be to reset the computer account in AD and retain the SCCM resource in case of machine rebuild scenarios. In case of task sequence not retaining the computer name, custom steps can be added in TS to set variables as required.

When I plug in my iPhone to sync, it starts but does not complete the process and several pieces of data are not being transferred to my iPhone from my MacBook Air.

Problem:
When I plug in my iPhone to sync, it starts but does not complete the process and several pieces of data are not being transferred to my iPhone from my MacBook Air.
Any help that you can provide in helping my iPhone accurately sync with iPhoto and iTunes will be greatly appreciated.
Symptoms:
1)   Sync: It’s not completing the sync. Below, I’ve provided all of my settings from the iTunes Summary tab so that you might tell me if I’ve selected any incorrect options. I prefer to sync the “old school” way – by connecting to the computer – as opposed to syncing over the cloud. Perhaps this is what’s causing the problem? Here is a list of the steps displayed in the iTunes window as the sync progresses:
waiting for sync to start (step 1 of 7)
backing up (step 2 of 7)
preparing to sync (step 3 of 7)
determining apps to sync (step 4 of 7)
preparing apps to sync (step 5 of 7)
importing photos (step 6 of 7)
waiting for changes to be applied (step 7 of 7)
syncing apps / copying 1 of 4 (App name) (step 7 of 7)
canceling sync
apple icon
2)   Photos: I've selected only certain of my iPhoto albums to sync to my iPhone. All of the albums are correct/complete in iPhoto. All of the albums are listed on my iPhone, both before and after the sync, but the albums are empty (no actual photos) before and after the sync. Perhaps this is tied to the fact that the sync isn’t completing, but because “importing photos” is one of the steps that the incomplete sync displays, I don’t know.
3)   Apps: When I launch iTunes and click on the Apps folder under the Library listing, then click on the Updates tab, iTunes searches for any Apps needing to be updated and provides a list. If I click on Update All, the Apps are successfully updated in iTunes. But, when I plug in my iPhone so that the updates will transfer to the apps on my iPhone, the updates don’t transfer to the apps on my iPhone and those apps still reflect that they need updating on the iPhone.
Other Potential Pertinent Info:
The flash memory hard drive on my MacBook Air recently died (perhaps a month or two ago). Apple had emailed me about a known issue and literally the next day, my MacBook Air crashed. I installed a new flash memory drive and re-installed everything from a backup off of an external hard drive. Everything seems to be working fine; it recreated accurately all of my software and data, including iPhoto and iTunes, the pictures and songs (respectively) for which are stored on that hard drive, as opposed to being on the flash memory in the MacBook Air itself. However, I don’t recall if the start of the sync problem described herein started happening at the same time that I replaced the flash memory drive. All I know is that the computer is working perfectly in all respects and that even as the sync is failing, it at least says that it’s doing the right things and looking in the right places (e.g., the list of albums on my iPhone matches the list of albums in iTunes, etc.).
Settings/Status:
MacBook Air
OSX v. 10.9
iPhoto ’11 v. 9.5 (902.7)
iPhone iOS 7.0.4
iTunes v. 11.1.3 (8)
Summary Tab
Backups (This Computer)
Options
Automatically sync when this iPhone is connected
Sync only checked songs and videos
Photos Tab
Sync Photos from iPhoto (429 Photos)
Selected albums, Events, and Faces, and automatically include (no Events)
Albums – 9 are selected

You need to download iTunes on your computer. iOS 6 requires the latest version of iTunes which is 10.7.

What is the difference between Azure RemoteApp Basic vs Standard Plans in terms of compute cores and memory?

So our customer has asked us to compare compare Amazon Workspace and Azure RemoteApp offerings for them to choose from. While looking at Amazon Workspace, it clealy defines bundles with specific CPU cores, memory and user storage. However, Azure RemoteApp
only specifies user storage and vaguely compares its basic vs. standard plans in terms of "task worker" vs. "information worker"
I tried looking up its documentation but couldn't find specific CPU cores that are dedicated per user in basic vs. standard plans. I have following questions:
Can anyone point me in the right direction or help understand how many CPU cores and memory are dedicated (or shared) per user in each plan?
Our customer would most likely need a "custom" image for their custom apps. Is it possible for us to choose specific CPU cores and memory for the users to be able to run their apps in azure remoteapp?
In case i am misunderstanding the basic difference between AWS workspace and Azure RemoteApp, i'd appreciate some help in understanding it as well.
Thanks!

Hi,
With Azure RemoteApp users see just the applications themselves, and the applications appear to be running on their local machine similar to other programs. With Workspaces users connect to a full desktop and launch applications within that.
1. Azure RemoteApp currently uses size A3 Virtual Machines, which have 4 vCPUs and 7GB RAM. Under Basic each VM can have a maximum of 16 users using it whereas under Standard each VM is limited to 10 users. The amount of CPU available
to a user depends on what the current demands are on the CPU at that moment from other users and system processes that may be on the server.
For example, say a user is logged on to a VM with 3 other users and the other users are idle (not consuming any CPU). At that moment the user could use all 4 vCPUs if a program they are running needed to. If a few moments later
the other 3 users all needed lots of CPU as well, then the first user would only have approximately 1 vCPU for their use. The process is dynamic and seeks to give each user their fair share of available CPU when there are multiple users demanding CPU.
Under the Standard plan a user will receive approximately a minimum of .4 vCPU assuming that the VM has the maximum number of users logged on and that all users are using as much CPU as possible at a given moment. Under the Basic plan the approximate
minimum would be .25 vCPU.
2. You cannot choose the specific number of cores and memory. What you can do is choose the Azure RemoteApp billing plan, which affects the user density of each VM as described above. If you need a lower density than Standard you
may contact support.

 " <xsql:set-page-param name='username' value='{@u}'/>"+
 " <xsql:set-page-param name='password' value='{@p}'/>"+
 " <xsql:query bind-params='username password'>"+
 " select 'Authenticated' from dual"+
 " where 'SCOTT' = UPPER(?) /* username */"+
 " and 'TIGER' = UPPER(?) /* password */"+
 " </xsql:query>"+
 "</page>";
DOMParser d = new DOMParser();
d.parse( new StringReader(xsqlPage));
XSQLRequest req = new XSQLRequest(d.getDocument(),null);
StringWriter sw = new StringWriter();
PrintWriter errors = new PrintWriter(sw);
Hashtable h = new Hashtable(2);
h.put("u","scott");
h.put("p","tiger");
req.process(h,output,errors);
output.println(sw.toString());

What are the minimum CPU and Memory requirements for R12 Vision instance?

We are in the process of trying to figure out what the minimum hardware requirements are for installing the R12 Vision instance. This Vision instance would only have 5 or less concurrent users. We may have to order a new server and we are wondering what the minimum CPU and memory would be? Oracle Support will not give us this information.
We aleady know how much disk space it will need.

Nio ByteBuffer and memory-mapped file size limitation

I have a question/issue regarding ByteBuffer and memory-mapped file size limitations. I recently started using NIO FileChannels and ByteBuffers to store and process buffers of binary data. Until now, the maximum individual ByteBuffer/memory-mapped file size I have needed to process was around 80MB.
However, I need to now begin processing larger buffers of binary data from a new source. Initial testing with buffer sizes above 100MB result in IOExceptions (java.lang.OutOfMemoryError: Map failed).
I am using 32bit Windows XP; 2GB of memory (typically 1.3 to 1.5GB free); Java version 1.6.0_03; with -Xmx set to 1280m. Decreasing the Java heap max size down 768m does result in the ability to memory map larger buffers to files, but never bigger than roughly 500MB. However, the application that uses this code contains other components that require the -xMx option to be set to 1280.
The following simple code segment executed by itself will produce the IOException for me when executed using -Xmx1280m. If I use -Xmx768m, I can increase the buffer size up to around 300MB, but never to a size that I would think I could map.
try
String mapFile = "C:/temp/" + UUID.randomUUID().toString() + ".tmp";
FileChannel rwChan = new RandomAccessFile( mapFile, "rw").getChannel();
ByteBuffer byteBuffer = rwChan.map( FileChannel.MapMode.READ_WRITE,
0, 100000000 );
rwChan.close();
catch( Exception e )
e.printStackTrace();
I am hoping that someone can shed some light on the factors that affect the amount of data that may be memory mapped to/in a file at one time. I have investigated this for some time now and based on my understanding of how memory mapped files are supposed to work, I would think that I could map ByteBuffers to files larger than 500MB. I believe that address space plays a role, but I admittedly am no OS address space expert.
