JVM takes more RAM than defined in -Xmx param on solaris

Hi all,
We have a problem on production installation of our product on Solaris paltfroms: jvm takes more (much more) RAM than defined in -Xmx param and without any OutOfMemory exceptions. (how itt possible at all ?)
The only JNI call in application is SAP interface connector, but application uses a lot of Runtime.exec() calls.
Is it possible to have such kind of "leaks" in java using JNI or Runtime.exec()?
I will be very appreciate for any tip how to find the root of this problem and how we can fix it ?

KDE 4.4 eating up more RAM than 4.3

Given the same settings on both versions and after numerous testing, upon bootup, KDE 4.4 is eating up more RAM than KDE 4.3, at least 25 MB more on the average. I realize the developers mentioned they fixed numerous bugs from the previous version, but shouldn't they be working on getting it lighter? Where's the most likely culprit for this additional RAM usage? Can it be attributed to the newer QT version 4.6.1, or something else? Opinions much appreciated, thanks.

As for preload, i installed that some time ago and after 1-2 months i found out that it don't give me a visible speedup on cold start of my apps. In fact, the only thing it was doing was making my linux boot very slow.
Well, it really is that simple. If I have spare RAM, I want something on my computer to start using it.
Preload greatly increases speed on my end on some apps. Mostly big apps, like Openoffice and Kontact, which starts instantly with preload, and takes forever to run if I disable it. It doesn't increase boot time at all for me (I just start it in background, the rest of the loading happens after login and is not noticable on my system). Guess our milage are different.

Don't complain about RAM-use unless you're running out. Free RAM is wasted RAM (and, worse, wasted money you spend on that RAM). If there's RAM not being used, a good OS will find ways to use it.
Instead of worrying about how to free up your used RAM, start worrying about how to use the RAM that is not being used (increase browser-cache, install preload, give Nepomuk more memory, etc).
Certainly free RAM is a wasted resource, but the point of the discussion is whether the increase in RAM usage on KDE 4.4 is a good use of RAM. It is quite possible that the increase in RAM usage is due to bugs introduced in the new code and tracing the exact cause is helpful when one wants to submit a bug report to the KDE team. The RAM saved this way could be used for more useful things in the next release of KDE.
True. I was making a general statement, not being specific to KDE. Memory leaks are obviously not RAM being put to good use.
In KDE 4.3 I found nepomuk all but useless. It slowed down my desktop and had a bad habbit of crashing Dolphin. Now it seems to run pretty well and I barely notice it, but it does take up a lot of my RAM compared to memory-usage in 4.3. But then, I feel like I'm getting something for my money. And I still got lots of RAM to spare, and no ideas on what to use it on.

thanks in advance...That may be because your client is displaying only the first few records when you are running the "SELECT *". But when you run "COUNT(*)", the whole records has to be counted.
As already mentined please read teh FAQ to post tuning questions.

i do not get good answers sometimes, so, i ask again.I think Alex answer to your post was quite complete. If you missed some information, continue the same post, instead of opening a new thread with the same subject and content.
You should be satistied with the answers you get, I also answered your question about global indexes, and I do think my answer was very complete. You may ask more if you want, but stop multiposting please. It is quite annoying.

Why import of change request in production takes more time than quality?

Hello All,
why import of change request in production takes more time than import into quality?

Hi jahangeer,
I believe it takes same time to import a request in both quality and production as they will be in sync.
Even then if it takes more time in production that may depend on the change request.
Thanks

More ram than specs call for

Specs for my emac specify support for 1GB of ram. In searching for additional ram (I presently have 512MB) I have found some suppliers that claim you can install 2GB (1GB in each of the two slots). I called and they said they have tested this and it works fine. I consider the company I called to be reputable. Has anyone heard of this? What would be the downside of trying it out - other than the extra cost? Is there some kind of power limitations or something that might harm my computer?
Thanks for any insight,
Doug

Ya if you do a search of this group, you will find this has come up a LOT of times and yes your Mac can use more RAM than 1GB if you want.
JIMacG5 I think is being a bit paranoid since, A) your eMac is probably long out of warranty anyway and B) Apple only tests up to whatever RAM was available at the time the model was in production. They do not test RAM for old models so many old models have outdates RAM specs and can use a lot more than they "officially" state they do.

All things being equal, does 4th gen quad core i7 (2.5GHz) need more RAM than 5th gen dual core i5 (2.7GHz) for same tasks?

Bought mid/late 2014 15" MBPr with the i7 2.5GHz and 16GB RAM. I'm within 2 week exchange period at Best Buy, and thinking of switching to 2015 13" MBPr with i5 2.7GHz and 8GB RAM for battery life and weight, and they don't offer the upgraded 16GB RAM option for any 13" models.
Needs to be Best Buy because of gift cards
Use docked at office 75% of time vs 25% out of office, so portability and battery life are nice to have but not as important as if I had 8 hour flights on weekly basis
See appeal of having 5th gen i5 in 13" vs my 4th gen i7 that will be updated this summer
Not a gamer and don't use Final Cut or other video editing, but I tend to leave several applications open and usually have between 1-3 GB free RAM of the 16GB total at any time according to my Memory Cleaner readings
Therefore, worried that 8GB is a non-starter as simple math says that I would have shortfall of 5-7GB RAM based on above readings, but wondering if dual core i5 will use RAM more efficiently than quad core i7
Any help greatly appreciated!

Also to note, would like this to last 4 years, which was reason that I bought the higher spec'd model even though I don't run games or video editing

Zfs destroy command takes more time than usual

Hi,
When I run the destroy command it takes more than usual.
I have exported the lun form this zfs volume ealier.
Later I have removed the lun view and deleted the lun.After that when I run the below command it takes more time (more than 5mins and still running)
#zfs destroy storage/lu

Is there a way to quickly destroy the filesystem.
It looks it removing the allocated files.

MBP Memory Upgrade Using More RAM than Before

Hey,
I have a 13-inch, late 2011 Macbook Pro with a 2.8 GHz Intel Core i7 Processor. I recently changed my 4GB memory (2 modules) PC3-10600 DDR3 1333 MHz to a Crucial 16GB PC3-10600 DDR3 1333 MHz.
Before the upgrade, the activity monitor would show memory used at around 3.98GB or so, and I was running only chrome with a few tabs open. Using chrome and a few more apps would slow down the computer significantly, though still usable.
After the upgrade, the activity monitor shows memory used at around 6.5GB with the same apps running (just chrome). My computer does run a faster and can handle a lot more apps.
My question is, why is my Macbook using more RAM after the upgrade?
Thanks,
Sebs

The short answer is that memory unused is memory wasted.
Mavericks is designed to decrease reliance upon mass storage, which is orders of magnitude slower than RAM. Mavericks will use all the memory available to it before resorting to using the swapfile. You are likely to find "swap used" to be zero, even with Google Chrome's notoriously profligate use of system resources.

Can I add more ram than suggested

I need to get some more ram for my imac that apple say I can expand to 16gb. I currently have the standed 4gb.
In the following article from pcworld i noticed the following (especially the bold)
All iMacs come standard with 4GB of memory, installed as a pair of 2GB modules. When you order an iMac through the Apple Online Store, you have the option to upgrade the memory to 8GB (a pair of 4GB modules) on all iMac models for $200, or to 16GB (four 4GB modules) on the 27-inch models for $600. The iMac has four memory slots located at the bottom of the iMac that are user-accessible. Since two slots are empty when you buy an standard-configuration iMac, you can easily add more memory. The 21.5 inch iMac has support for up to 16GB of memory; third party companies are offering 32GB memory upgrades for the new 27-inch iMac.
Does this mean that I can technically go up to 32gb? Is there a down side to adding more the an 16gb suggested.

Although you can install up to 16 GBs of RAM in both 21 and 27" models, I can not confirm that you can install 32 GBs in the 27" model. You might check OWC to see what they say.

Mink,
If the calculation script ,which you are using is the same which performed better before and data being processes is same ( i mean data might not have exceptionally grown more).Then, there must be other reasons like server side OS , processor or memory issues.Consult sys admin .Atleast you ll be sure that there is nothing wrong with systems.
To fine tune the calc , i think , you can minimise fix statements . But,thats not the current issue though

Why HTML report takes more time than the PDF one?

Hi,
I have created report in Reports 6i. When I run the report on the web with FORMAT = PDF it runs very fast and shows all the pages in 2 minutes. But when I run with
FORMAT = HTML it shows the first page in 2 minutes, after that it takes lot of time to show the remaining pages. If the total pages are more than 40, the browser just freezes
Can somebody give me the reason?
Is there any way to rectify this?
Thanks alot.
Ram.

Hi Senthil,
Iam running with the below parameters.
Format : HTML
Destination : Screen.
My default browser is IE. When I try to run using Netscape it showed only 1 page out of 34 pages.
When I run Format as PDF it is faster but font size is small when it opens up. Offcourse user can zoom it.
If I increase the report width from 11 to 14 the font size becomes very small when it open up in browser.
Is there any way that I can set up zoom when I run as PDF?
Thanks for your help.

Why Yosemite used more ram than maverick?

How did you transfer the backup? It sounds like you may have transferred more or less than you should have, which is causing you problems now. Mountain Lion's memory requirements should be about the same as Lion's.
Note that your problems may or may not be RAM-related. Don't be too concerned about low free RAM... free RAM is wasted RAM, and low free RAM should not be a problem in and of itself. If you have low inactive RAM in addition to low free RAM, though, or if your page outs value in Activity Monitor is too high (10% or more of page ins), then it's probably RAM-related.
Still, you definitely should be able to run the same tasks on newer hardware in Mountain Lion just as well as you did in Lion, on the same amount of RAM. If that's not the case, something's wrong and some troubleshooting will be needed. You could try some of the tips in my Mac Performance Guide, though there may be some more specific steps you can take based on the answer to my initial question.

all our cronjobs are running
fine or not
the above mentioned SQL is part of one of the processes, takes about 41 min on 9i and the same taking about 52-56 minutes on 11g.
Also, I took out every in-line SELECT statement and ran in both envs. looks 11g is executing them fast. But as a whole it takes about 10-12 mins more on 11g. So
I suspect that its problem with INSERT statement. So I just wrote a simple PL/SQL block to insert 1m records and tested on both.
INSERTION OF 1M records 1:46 min 2:06 min
count(*) 0:0.35 sec 0:0.17 sec
delete 0:28.9 sec 0:36.72 sec
rollback 0:32.19 sec 0:41.36 sec

JVM takes more RAM than defined in -Xmx param on solaris
