Waht's the common practice to allocate memory to sybase?

Suppose I have a dedicated server(Redhat Linux) for Sybase ASE 15.2. On this box, there are 10G memory available. How many RAM I can assign to Max Memory to Sybase with common practice? for example, if 80% of total physical RAM is proper portion?

Here is what the official product docs say on this issue:
SyBooks Online
What I would do is look at the OS documentation to see what it says about the memory requirements for the OS itself. Since this is a dedicated system, ASE can be assigned the rest. On a system shared with other processes you would want to be less aggressive.
I would think ASE could easily be assigned 9 GB on a dedicated 10GB system, and probably some more beyond that.
If you can't determine a value for what the OS needs, you can experiment with increasing the memory for ASE while keeping an eye out for any memory page faults. Once you start seeing page faults, back off a little on ASE's configuration. You do not want ASE's memory moving in and out of swap.

How to populate tax area for IT 207? what is the common practice?

Gurus,
How to populate tax area for IT 207? what is the common practice?
The residential address IT 0006 is a new your address with ZIP code 10001
PA30 for IT 207 displays 4 tax areas for the new york address.
FED     Federal     0000-0001      99999-9999
NY     State of New York             14999-9999
NY01     New York City          14999-9999
NY02     Yonkers                   14999-9999
I thought, each zip code will map to only one tax area.
Thanks,

This is the real world ! SAP does not design tax area based on zip codes. In our company, the tax lady calls the tax authorities to check what zip codes fall under that tax authorities.
and BTW, with new BSI upgrade, you will find 12 more tax authorities for NY.
Cheers !!!!

Common Practice For Storing Application Data Files

During my application development targeting for XP and Linux time, I will store my application data files (Files where user may create, modify, rename, delete...) same path as my application directory. For instance, if my application is installed in :-
C:\Program Files\MyApp\MyApp.jar
All my application data files will be located in
C:\Program Files\MyApp\Config\ directory.
This works quite well until Vista introduce UAC. Vista will not allow write opration to C:\Program Files\MyApp\Config\ folder (Config folder is being created during installer execution). However, to support legacy application, Vista use a workaround (Virtualization) for application to write. For example, MyApp.jar want to perform write on
Real path :-
C:\Program Files\MyApp\Config
Vista will redirect it to :-
Virtual path
C:\Users\<account>\AppData\Local\VirtualStore\Program Files\MyApp\Config
Please refer to the links for more detail
[http://www.codeproject.com/KB/security/acl_common_data.aspx?display=Print]
[http://www.codeproject.com/KB/vista-security/MakingAppsUACAware.aspx]
However, this introduce several additional problems [http://support.microsoft.com/kb/927387]
May I know what is the common practice for storing an application data files? The below are my several thoughts
(1) Writing to
* Windows XP - %systemdrive%\Documents and Settings\All Users\Application Data
* Windows Vista - %systemdrive%\ProgramData
* Windows 2000 - %systemdrive%\Documents and Settings\All Users\Application Data
* Windows Server 2003 - %systemdrive%\Documents and Settings\All Users\Application Data
* Windows 98 - %systemdrive%\Windows\All Users\ Application Data
which we may retrieve through "CommonApplicationData", using the API function SHGetFolderPath. However, how can we do that in Java? How to make compatible with Linux?
(2) Writing to user home directory through "user.home" properties. Create a folder .MyApp and write the application data on it.
Any input and suggestion are welcomed.
Thanks!

Hello,
Based on the error, unable to allocate memory for mutex; resize mutex region,
have you tried increasing the mutex region?
The documentation on the setMaxMutexes method is at:
http://www.oracle.com/technology/documentation/berkeley-db/db/java/com/sleepycat/db/EnvironmentConfig.html#setMaxMutexes(int)
You can run db_stat -x
to display the mutex subsystem statistics.
You'll see the information for statistics like:
Mutex region size
The number of region locks that required waiting (0%)
Mutex alignment
Mutex test-and-set spins
If that does not look to be the problem, just let me know.
Thanks,
Sandra

Common practice to stop thread - checking flag or checking interrupt status

Hello all, from the official document from Sun http://java.sun.com/j2se/1.4.2/docs/guide/misc/threadPrimitiveDeprecation.html , I was understand that the common practice to stop a thread is to
   private class StockMonitor extends Thread {
        public StockMonitor() {
            thread = this;
        public void run() {
            final Thread thisThread = Thread.currentThread();
            while(thisThread == thread) {
        public void _stop() {
            thread = null;
        private volatile Thread thread;
    }However, the need to have an extra flag is rather cumbersome. Hence, is it a common practice which we can stop a thread by checking its interrupt status? What is the pros and cons of the two methods?
Thanks
    private class StockMonitor extends Thread {
        public StockMonitor() {
            thread = this;
        public void run() {
            final Thread thisThread = Thread.currentThread();
            while(thisThread.isInterrupted()) {
        public void _stop() {
            interrupt();
    }

However, I thought checking thisThread.isInterrupted() is enough? As the following case...
public void run()
    while(Thred.currentThread().isInterrupted())
        // Do something
        try {
            Thread.sleep(1000);
        catch(InterruptedException exp) {
            // Must break while loop from here. This is because interrupted
            // flag had been reset. If not, we will not able to
            // exit this while loop.
            break;
    }So, is there any need for a boolean type status flag? Can you please provide me any case, where it is impossible to achieve by just using checking thisThread.isInterrupted() checking?

I can no longer access Safari on my ipad. I get the error:the operation couldn't be completed. Cannot allocate memory. Help please!

I am not able to access Safari on my ipad. I get the error message: The operation couldn't be completed. Cannot allocate memory. Can anyone help please??

Try this first.
Go to Settings>Safari>Clear History, Cookies and Data. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button.
If that doesn't work, reboot the iPad - or quit all apps and restart.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.
Quit all apps completely and restart the iPad. Go to the home screen first by tapping the home button. Double tap the home button and the task bar will appear with all of your recent/open apps displayed at the bottom. Tap and hold down on any app icon until it begins to wiggle. Tap the minus sign in the upper left corner of the app that you want to close. Tap the home button or anywhere above the task bar. Restart the iPad.

The merge process could not allocate memory for an operation; your system may be running low on virtual memory. Restart the Merge Agent.

I encountered this problem on our SQL2012 and I have tried different scenarios (see below) to no avail. I have decided to give up and check if someone here has encountered this and resolved it.
One thing I know, it's not a memory issue. Both servers we're using has lots of memory to spare and we monitor the memory as the replication goes through it's steps.
I hope someone can help me on this. Thanks!
The Error:
The merge process could not allocate memory for an operation; your system may be running low on virtual memory. Restart the Merge Agent.
Our Scenario
We're using SQL Server 2012 SP1. All subscriptions are pull based.
We're using direct Merge Replication (not FTP or web sync)
We already have 10 active replications with larger databases. Only 1 has this issue.
Database size is less than 5 GB
Rebuilding the publisher is not an option.
What have I tried?
There is no memory problem --- we have lots to spare
I have tried re-initialization of the database. Same problem.
I tried deleting the database and reinitializing it. Same problem
New snapshot. Same problem.
I tried changing the subscriber server but still same issue.
MCP, MCSD, MCDBA (ANXA)

Here is the result for the sp_configure on our subscriber. We're doing a pull on the server with the issue.
name
minimum
maximum
config_value
run_value
max server memory (MB)
128
2147483647
2147483647
2147483647
In addition, I made a comparison between the working servers and the one with the issue -- there seems to be a difference in the service pack. Publisher has none but the subscriber is operating on SP1. But still strange as only 1 database is affected.

Using Disc Utility to copy my hard drive to a brand new external drive and am having the error "Unable to create...(Cannot allocate memory)".

I'm not very tech savvy but am trying my best to use Disc Utility to copy my hard drive to a brand new external drive and am having the error "Unable to create...(Cannot allocate memory)".
Last night no problems, woke this morning and it was freezing so I forced a restart and got the grey screen with the folder and question mark. Ran off to best buy to get an external drive... Please help! Thank you!

I have done both. When I hold down the "C" key it pauses for a few seconds while the cd spins and then the flashing folder icon appears.
Could be you have the wrong cd/dvd. The mac will only boot a supported cd/dvd for your machine. The flashing question mark indicdates your machine could not find a valid os.
When I hold down the "option" key for the startup manager the cursor comes up and moves but the actually manager doesn't come up no matter how long I leave the laptop on.
Not sure. Could be your machine does not support the startup manager. You would think the machine would ignore the key.
Where did you get the dvd? What is the number on the DVD?
What machine do you have anyway?

Hi again OGELTHORPE.
I've already run two hardware tests. One quick one and one extended one. It was unable to pick anything up.
It's like everything is running perfectly, but when I go to erase the HDD or partition it, it pops up with the error message. Even when I try to erase and partition using "Terminal", I received the same error message.
It's beginning to do my head in, but will see if replacing the SATA cable will make any difference. If it doesn't, I'll hazard a guess it could be the Logic Board.
Thanks again for your suggestions!

I would like to upgrade my OS to the latest version. I now have 10.6.8 and my machine has 1Gb of memory. Need 2Gb for the new OS. Is is possible (and practical) to add memory to a machine that's five years old?

You can put two 2gb RAM sticks in your model 2,1 but it can only use 3,3gb. This is a hardware limitation and cannot be changed.
http://en.wikipedia.org/wiki/3_GB_barrier
http://www.everymac.com/systems/apple/macbook_pro/faq/macbook-pro-core-2-duo-3-g b-memory-limitation-details.html
OWC tests have found that there is a slight speed increase with having two 2gb sticks in rather than one 1gb and one 2gb. Your model is in the gray lines at the bottom of the graph. http://eshop.macsales.com/shop/Memory_Benchmark/Apple_MacBook/
You can buy Lion for $29 from the App Store witht a model 2,1 MacBook. Lion will require at least 2gb of RAM but really needs 4gb to run smoothly. As for programs see this list for compatibility with 10.7 http://roaringapps.com/apps:table
Lion doesn't run any Power PC programs. To see if you have any Power PC programs go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up select Applications under Software. Then look under Kind to see if any of your applications are listed as Power PC. Universal and Intel will run under Lion.
Before Mac switched to Intel processors they used Power PC processors from 1994 to 2005. Power PC 601 through 604, G3, G4 and G5. Applications written for the Power PC processors need the application called Rosetta to run on Intel processors. This was part of the Operating System in 10.4 and 10.5 but was an optional install in 10.6. With 10.7 Lion Apple dropped all support for Power PC applications.
These are good online stores for Mac compatible RAM
OWC http://eshop.macsales.com/shop/memory/MacBook/DDR2/ - They offer Mac tested RAM at very good prices.
Crucial Memory http://www.crucial.com/ - good place to buy RAM from all over the world. They also have an excellent memory selector that allows you to choose memory based on your computer's model
Data Memory Systems http://www.datamemorysystems.com/apple-memory.asp - another good, cheap place to buying RAM if you live in the U.S.

My internal boot drive is NOT showing up in the Event Library in Final Cut X. My external raid drive is showing up.
I am also getting error message "The operation couldn’t be completed. Cannot allocate memory" when attempting to create a new "event". Any ideas?
If I had a application disk, I would unistall and reinstall FCPX. I am assuming there is a way do do this without a disk - just have not been able to easliy find out how.

Well it did NOT work. Here is a screen capture as FCPX loads showing the drive while it loads. Then when it is loaded, NO drive showing up in the Event Library ( I have turned off the external drive).
ANY ideas . . . . Anybody . . . . APPLE?

I need to say that I can create a new database in that server by dbca that its
sga_max_size is 9632M and pga_aggregate_target is 3206M
Do you know what is wrong ? Do you know why RMAN can't allocate memory to the virtual instance ?
thanks

The database which could not start is because of the low memory on the system or in the sga_max_size there is high value set. So the system could not allocate so large memory as it does not have free so much. There may be other reasons like OS limitation in order of usage the memory.
Set a lower amount of memory in the database.
Eg:
SQL> alter system set sga_max_size=1600M scope=spfile;
System altered.
SQL> alter system set sga_target=1600M;
System altered.
refer the link it will be useful:http://arjudba.blogspot.com/2008/05/startup-fails-with-ora-27102-out-of.html
else use manually copy the spfile/pfile to the new server

POSIX reports: The operation couldn't be completed. Cannot allocate memory

Hi all.
Please forgive my naivety. I'm a newbie here.
I have searched endlessly to find a solution to my problem, but cannot seem to find one.
I have just replaced a hard drive on a 13" Macbook pro (purchased end of 2009). It developed a fault, and would not boot. When turned on, would only produce a blank screen with a flashing folder featuring a question mark.
When going through disk utility, the system could not detect any internal hard drive, which made me believe it was faulty.
I ordered a 500GB Toshiba Hard Drive, and installed it as it should be. In Disk Utility, the system detects the Toshiba hard drive (it comes up in the list you'd expect it to). Whenever I go to 'Erase' or 'Partition', however, I get the following error message.
"Disk Erase/Partition failed
Disk Erase/Partition failed with the error:
POSIX reports: The operation couldn't be completed. Cannot allocate memory"
Is anybody able to offer this novice any suggestions as to what I might do? I have tried some "Terminal" entries, but they don't seem to help in the slightest.
Thanks in advance,
L.
P.S. The Macbook is using Snow Leopard.
