Sudden increase in memory space

We have developed an application using the Hyperion 9.3.1.
We are trying to load data and the data load itself is taking lot of time.
Again, the memory space is getting increased drastically (almost to 100%).
We see lot of page files being generated.
What can be the reason for this sudden increase in memory space utilization.

you should consider the folllowing factors for sudden increase in memory space
1.Minimize the no of hierarchies otherwise it leads to increase in the size of aggregated data and slows down view selection
2. remove fragmentation
3.Compact the outline to remove the records of members that we have been deleted
4.create transparent partition if neccessary which leads to enable write-back partition.By doing this we can reducethe size of the Database and reduces calculation time.
5.use compression if values are grouped together in consecutive members on dimensions or hierarchies rather than spread throughout the outline with lots of
#missing data between values.

How can I fix a drastic and sudden increase in memory usage?

Before I start, I've already been having slight issues since the middle of last year, but I thought nothing of it. Firefox starting up using a good chunk of memory was normal, and I could run it alongside my other programs just fine. However, about 3 or 4 days ago, Firefox has started to spike in memory usage, to the point where it slows my entire computer down, will not load pages, and it's generally a mess. I always have to force close it, too, because whenever I close it conventionally, it's still open in the background. I've been having the background issue for a few months, but it's never been a large problem until the last few days. I had thought, at first, that it was the result of some programs that got installed as part of another installer. I had no issue with the installer, considering it came from a trusted forum for game design on an official topic, from a veteran member. However, it installed multiple toolbars and multiple programs. I went through all of them, uninstalled them, cleared my registry, everything was gone. However, this memory problem reared its ugly head, later. I uninstalled, reinstalled. Didn't work. I tried to reset firefox, but it stayed open in the background, and I could not reset it. I disabled my addons (ones I've been using for over a year, now), nothing. I tried to open Firefox with all addons disabled, but it stayed open in the background and refused to re-open properly. I'm actually on another browser right now because Firefox is no longer working for much of anything... I also put a couple of attachments up to show the increase in question. It starts at around 270,000 K (though the screenshot shows around 312,000), then after about 4 or 5 minutes on my homepage, shoots up to well over 1,000,000 and it basically stops functioning. If anyone has any additional steps they think I could take, I would appreciate it.

Sudden increase in disk space?

I've been working with 20 GB or so available on my startup disk for around 6 months now.
A couple of days ago I got the Startup Disk almost full message. I saved my work and rebooted.
That solved the problem and I gained 3-4 GB.
Yesterday morning suddenly I had 100+GB of free disk space!
No emptying the trash, no time machine running, norhing.
Any ideas on this matter?
I'm running Lion 10.7.5 on an iMac

I work mainly with big video files. Almost all of my work is on external hard disks. They seem to be fine. So I have my stuff backed up. But I don't run Time Machine or any backup software.
I've read that if you are using Time Machine there is a discrepancy because of snapshots, but as I mentioned, I don't use Time Machine.

Short dump due to Memory Space

Hi Experts,
I have an internal table whose width is 3576 characters. My selection criteria is selecting approximately 1 million record from the database table.
Out of the 3576 characters, I m not even filling 150 characters a row using selection fields.
The short dump is as follows:
Error analysis
    The internal table "\PROGRAM=ZPMWO_DSR_RECONCILIATION\FORM=RECONCILIATION\DATA=
    LT_VIQMEL_I" could not be further extended. To enable
    error handling, the table had to be delete before this log was written.
    As a result, the table is displayed further down or, if you branch to
    the ABAP Debugger, with 0 rows.
    At the time of the termination, the following data was determined for
    the relevant internal table:
    Memory location: "Session memory"
    Row width: 3576
    Number of rows: 1035860
    Allocated rows: 1035860
    Newly requested rows: 4 (in 1 blocks)
How to correct this?? I mean how do i increase the memory space required for this process??

Hi,
Check there is not an endless loop which is appending data in the internal table.

Sudden increase in native heap memory

Hi all,
we are using JRockit 26.4 and currently configured with 1800MB heap on windows 2003 with /3GB switch.
We noticed that after the weblogic server is started the total memory (java heap + native memory) lingers around 2550 MB... (We monitored this using perfmon -> virtual bytes of java process)
after couple of days run, the native memory suddenly increased by 300 MB, taking the total virtual bytes to 2850 MB.
Do we know what could be the reason for such a sudden increase?
Thanks,
- Pritam.

I don't believe this is documented anywhere unfortunately, and it might vary depending on the exact JRockit release. But the key thing to watch out for is growth, regardless of which component it is. If you see that, post a question here and we'll find someone to tell you what the issue is...
That said, here's an example printout and some guesses from my side.
[JRockit] memtrace is collecting data...

---------------------!!!Total mapped means mapped virtual memory, eg the largest size the JVM can be expected to grow to. This is typically on the same order of magnitude as the Java heap size (Xmx).
Total in-use is the actual memory in use, this is the current "memory footprint" of your process.
executable refers to JIT compiled code, I believe.
Java-heap is the heap (duh).
Stacks should be the thread stacks (where local variables are stored).
classes is native memory used to store bytecode etc. If this grows, it may be because you are generating classes dynamically and they are not getting cleaned up because there are still live instances. Or maybe you're running with -Xnoclassgc.
threads can grow if you start a lot of threads and don't let them die.
Stuff under malloc:ed memory is mainly misc JVM metadata.
unaccounted for memory is...everything else. The most common leak involving unaccounted-for is native byte buffers (DirectByteBuffer).

Increase memory space?

I run out of memory space, apart from deleting files, is there anything I can do?

Welcome to Apple Discussions!
Yes, see my user tip:
http://discussions.apple.com/thread.jspa?threadID=122973&tstart=20
You can also get a Parallel ATA hard drive up to at least 120 GB, and depending on your iBook G4 age, possibly up to 160 GB. See this article to find out if your Mac supports 160 GB:

What's in the JVM Process's Memory Space?

Hello
I'm noticing the following behavior on an NT system. On
application startup, I see
Total Heap 9 MB
Used Heap 5.5 MB
java.exe memory (from NT Task Manager) 36 MB
After a "login" operation which loads a few more
classes:
Total Heap 12.5 MB
Used Heap 8.2 MB
java.exe memory (from NT Task Manager) 53 MB
Heap memory leaks have been ruthlessly suppressed
(thanks to OptimizeIt and careful programming). The
behavior I do not understand is that the NT process
(java.exe) increased in size by 17 MB when the Java
heap increased by only 3 MB. The .jar file in which the
application resides is less than 1 MB, so this 14 MB
growth can not be attributed to new classes being
loaded.
Does anyone know what is going into the process
memory space of java.exe? It tends to grow larger
and larger.
Should I even care? Do I want a large allocation of
process memory for java.exe, or will that hamper
performance of machines with less physical memory?
Posts on related topics in this forum have sometimes
advocated allocating a lot of memory to the JVM with
-X options.
Thanks

Hello
I am facing exactly the same problem on NT. However, on 2000 Server this problem doesn't seem to exist. Are you, by any chance, using JNI? We are extensively using JNI in our Servlets and found that there is definitely some momory leak there. We could not figure out any substantial leak at Java end. In NT's "Task Manager" java.exe is always listed first and very rarely the memory usage seems to come down. On 2000 Server the performance is far better.

How to increase the Heap space of Jdeveloper for about more than 512 MB?

When starting JDeveloper, the application within JDeveloper is throwing the error message:
"could not reserve enough space for object heap"
and a windows popup with the following error message:
"Unable to create an instance of the Java Virtual Machine Located at path: ..\..\jdk\jre\bin\client\jvm.dll "
To resolve these issues, i know that adding the following in ide.conf , jdev.conf will help.
AddVMOption -XX:MaxPermSize=512M
AddVMOption -Xmx512M
AddVMOption -Xms512M
I have got 10 GB of RAM in my desktop machine and virtual memory of 15 GB (page size). I am not able to increse the heap space of Jdeveloper for about more than 512MB. This is really frustrating..I had to restart my jdevloper after 3 or 4 deployments.....Has anyone tried success in increasing the heap space in jdeveloper for about 2 GB?
Regards
Prasath.C

Yes, i know that -XX:MaxPermSize has nothing to do with Heap Memory. I Just pasted all my configuration settings to know if some thing or the other has caused the issue.... After hearing few people who increased the heap space to more than 512m , i played with those settings again and figured out few things...Mine is Jdeveloper 11.1.1.4, 64 bit Windows 7 environment, 64 bit Java/ JDK.
First, i was deceived by one suggestion in forum that, keeping max and min heap memory to same size always will yield in good performance...From that time on wards, i was always increasing both and was never able to move more than 512m..But this time, i kept the min memory as constand and kept on changing the max memory ..
Jdev.conf
AddVMOption -XX:MaxPermSize=512M
AddVMOption -Xmx972M (I was never able to increase more than this size, though i have around 10GB RAM, if not Jdev doesnt startup)
AddVMOption -Xms512M
Ide.conf
AddVMOption -Xmx2048M (here i was able to increase)
AddVMOption -Xms512M
But even then, i was not seeing my changed settings at the time of deployment...
starting weblogic with Java version:
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b51)
Java HotSpot(TM) Client VM (build 17.0-b17, mixed mode)
Starting WLS with line:
C:\Oracle\MIDDLE~1\JDK160~1\bin\java -client -Xms512m -Xmx512m -XX:MaxPermSize=512m -Dweblogic.Name=DefaultServer ..........
Then i changed again into
setDomainEnv.cmd of my default domain
set USER_MEM_ARGS=-Xms512m -Xmx2048m -XX:MaxPermSize=512m
Then i stared my deployment...this time i could see a real boost in deployment...and my page was launched in a fraction of minute..
tarting weblogic with Java version:

Sudden increase in Tablespace - Oracle 9.2.0.8

The oracle tablespace increased suddenly but without loading the actual data. On 06/15, the tablespace has a free space on 1.5G, but all of a sudden, all 1.5G has been consumed and casued the batch job to abend due to lack of space in the tablespace. The tablepace was increased by 2.5G and the batch job ws successfully completed. Till now ( after 1 month) there was no decrease in the free space of the tablespace (still 2.5G) and there was a increase in the size of the tablespace.
Please could you help in sudden consumption of the free space by the tabllespace. here are the tablespace storage details.

Hi All,
I got the answer. It is a bug in oracle 9.2.0.8. Oracle support has given as patch to implement and it should resolve issue.Here is the quote from Oracle support " It seems you have hitting the known Bug 5987262 duplicate of Bug 5890312 Unexplained increases in unformatted blocks in a tablespace ..This issue is also addressed by article : Note 469985.1 Ext/Mod Sudden Increase in Unformatted Blocks "
Thanks for your support

Factors for increase in memory occupied by Oracle 11g database

I wanted to know all the possible factors which can account for the increase in the memory required for an Oracle 11g database. Let’s take an example,
1) Say if the memory allocated for an Oracle 11g instance is 8GB which is 50% of the memory of 16GB allocated to the machine on which Oracle 11g is installed.
2) The max sessions are 300.
With this example in mind, I had the following queries:
1) Is the memory taken by 100 sessions or 300 sessions going to be within the limit of 8GB allocated to the Oracle?
2) Say if the max sessions is increased to 400, would the memory taken the 100 extra sessions would be within 8GB or would that be extra?
I hope my query is clear.
Please revert with the reply to my query.
Regards

Memory is allocated for the session only when that session is created by the listener, and the memory used by that session will fluctuate depending on the workload it's doing.
300 or 400 it won't pre-allocate all the memory for the fixed maximum number of sessions, it's dynamic. What oracle does is allocated all the memory you gave it in the PGA and the SGA and will do it's best to work with it for the current workload, it won't suddenly eat more memory without you telling it's okay to.
The only scenario I could see this happening is if you have a lot of sessions and a small PGA. In that case, oracle does go ahead and eat more memory than you gave it because it can't make due with the current PGA. So it eats more memory so sessions can be created and maintened. See PGA over- allocation.
To quote the good ol' docs:
Over allocating PGA memory can happen if the value ofPGA_AGGREGATE_TARGET is too small. When this happens, the Oracle Database cannot honor the value ofPGA_AGGREGATE_TARGET and extra PGA memory needs to be allocated.

Many thanks!

Check what is using the memory and if that is necessary.
1. can you safely shrink the SGA ? you would need to check the AWR reports, or recommended sizes.
2. can you safely shrink the PGA ? you would need to check the AWR reports, or recommended sizes)
3. can you reduce the number of processes ? (are there lots of idle processes ?)
4. can you tune sql to use less memory ?
If you can't reduce allocated memory, check if you can add RAM to the server / container.
If you still think you need to increase swap, you may need to add another disk (what is /dev/md/dsk/d60 ?). You can easily google for the Solaris commands to add swap, but if you are not familiar with this process I would not recommend you do it by yourself. Ask Oracle Support to provide the commands, and TEST them on a DEV box, followed by reboots etc to confirm it works.

Increase JVM memory using Java Code

Hi Friends
I am in a critical situtation and not able get the solution. My application is huge and need of increase in JVM memory. I am able to increase JVM memory in command prompt
java -Xmx500m classname
Simarly I am able to run jar file also
java -Xmx500m -jar sample.jar
I need to know how to set JVM memory for executable JAR. When I just double-click the JAR application load and i am getting Out Of Memory. I dont what ti use command prompt to execute. Please help me with this program. Thanks in advance

I gone through the code of ImageJ software. ImageJ is
a freeware and wrtten in Java. They are setting jvm
memory in code, getting the description of the code
was difficult.
long memoryBytes =
s = Runtime.getRuntime().maxMemory();
     long memoryMB = memoryBytes/1024/1024;
     long memoryDiff = memoryMB - 64;
String s = "Runtime.maxMemory: " + memoryMB +
B + "MB\n";
     s = s + "Difference: " + memoryDiff + "MB";
     System.out.println("s..." + s);
The above code will give you the memory allocated for JVM. Yes.
When there is a way to find the memory space,
there should be some way to set it. No.
I am still trying to set the memory in code r using external resource.Read reply 4.
I want to just give the executable jar to users. They
are not satisified with the bat file and hidding
command prompt in background.You may be able to use Runtime.exec() to launch another instance of java, with whatever heap setting you desire.

Memory space using a 32bit Java process on Redhat Linux

I have a java process that I need a lot of memory for. Its a 32 bit process, and I have no desire to have it as 64bit due to the huge pointers it forces.
So I know I can turn to Solaris where I will have close to 4GB of memory available for this process (right?). But are there Linux alternatives? I am especially curious regarding Redhat on intel64 machines as I have (which is the common desktop hardware nowadays).
I heard about the hugemem kernel for Redhat, but I am lost understading its nature. It is said it is not available for v.5 for x86. So is it available for the intel64 processors as I have? And what is the max memory space for a java process?
Any other bit of information about java 32bit process running on a linux flavor on an intel64 machine will be greatly appreciated.
thanks in advance!

I'd say this is normal. There are a few things to consider when looking at an application like this:
1. The 14 MB your process consumes include the memory required to load the java virtual machine. That is, all the base classes, native links, the just in time compiler etc. 14 MB isn't a lot, all things considered.
2. When you display a message box, java will load additional classes and resources. They increase the heap size, though not really by 4 MB. Java preallocates portions of memory for the heap. If, for instance, your application consumes 16 MB of memory and you allocate another MB, the heap size may grow to 32 MB. Having a free section of heap space to spare increases performance, since java won't have to ask the underlying system for free memory every you create an object. You might want to check out your program in JVisualVM (deployed with every JDK6), which will tell you how much of the allocated heap size is really in use, or you can rely on the according methods in the Runtime class.
3. The JVM is capable of 'heap shrinking', meaning it will return allocated sections of memory to the OS once in a while. However, it will not do so unless the heap size is significantly larger than the used portion of the heap (otherwise, it would defeat the purpose of preallocating memory). So if you allocate 2GB of RAM when clicking your button and allow this memory to be cleared by the garbage collector, you'll observe that the heap will shrink again eventually.

Increasing Heap Memory

How do I do to increase the memory available to the JVM? I have an AVLTree class that I am trying to test how many nodes can hold, but even though I have tried on PCs ranging from 128MB to 2GB of RAM, the results is always the same: + - 2.3 million nodes. I have used -x option to increase heap size but that does not seem to work.

Hi,
I encounter the same problem with using 1G RAM & JRE 1.5 & running applet in IE.
The IE memory usage always run on maximum 139000K. Even I tried "java -Xms64m -Xmx512m" & "java -Xms256m -Xmx768m", the memory usage still in 139000K, and Java console shows "Exception in thread 'AWT-EventQueue-2' java.lang.OutOfMemoryError: Java heap space". How can I solve it?
Thanks.

My iPod touch will not let me download more apps, though I have sufficent memory space, and other internet based functions are running...

Try the following to rule out a software problem:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
If still problem make an appointment at the Genius Bar of an Apple store since it appears you have a hardware problem.

However, since it works with other networks that really suggests a problem with your network.
