Memory Swap?

I have a 15" MacBook Pro (early 2011) that I replaced the 4gigs of RAM with 16gigs.
I also have a 17" MacBook Pro (early 2009) that also has 4gigs of RAM. Was thinking of replacing the RAM I took out of the 15" into the 17" but not sure from the specs if they are any better.
Looks like they are all 2GB DDR3 chips.
Anyone know if the 2011 RAM is any better?
Thanks!

Actually I upgraded the 2011 to 16gb of RAM and added an SSD (and took out the superdrive to keep the old drive for extra storage).
Swapped the drives into the 2009 while the other is in the shop. The SSD definitely makes a difference. Actually considering putting the 16gb in the 2009 and seeing how it goes. Not sure how the video cards and processors compare though so might not be worth it. Won't have money to upgrade for awhile (and they don't make 17" MBP anymore *sob*).
I sure do miss the 17" screen though. I guess the other option is to get an external monitor and vertical stand to use with the 15". My deskspace is limited so not sure if that will work; it's a "secretary" desk so the desk space actually folds up (have to work with limited space in NYC).
Definitely don't have room (or money) for a desktop currently and I like having a laptop to sit in different places in the apartment. Don't take the laptop out as much now that I have an iPad Mini anyway.

Do itabs in ABAP program memory swap out when the program is swapped out?

Do itabs in ABAP program memory swap out when the program is swapped out by the app server scheduler?
If so, has anyone compared the time it takes to open/close an Oracle table n times with the time it takes to swap an itab of 50M in and out n times?

Andrew -
Although your suspicion appears to be wrong (according to the answer provided by CharlesF below), I'm awarding 6 because your answer indicates that you are at least sensitive to the issues involved here (which is better than 90% of the SAP practitioners out there.)
However, I do want to take strong issue with you on the matter of how much available "multi-gig" memory is available, because this is irrelevant to the issue at hand.
The question is: how does the swapin/out of large program memory affect the scheduler on the app server?
This is a queueing theory issue that has nothing to do with how much memory is out there.
Back in the days when folks had to know a little queueing theory (to evaluate the pro's and cons of ISO vs SNA and token-ring vs other protocols, everyone understood that if you ask the scheduler to repeatedly swap "alot" and to do so very often, then there will be a profound ripple effect on system performance, not just for anyone "job" or "program", but for any and every job or program.
The reason is very simple, and the folks who taught the ISO/SNA seminars always used it: traffic flow on passenger highways is always best when there are few trucks travelling with the cars. This is why the New Jersey turnpike sometimes splits into two "cars only" and "trucks and cars" highways, and why many other roads have "right lane" only restrictions for trucks in certain areas that tend to get congested ...
Anyway, always a pleasure to chat with you ...

Memory Swapping - help me make it stop

Hi All,
I am configuring a new machine with Oracle 10g running a single unicode database (db size is about 2GB) and during testing I am experiencing major memory swaping and my linux server is slowing to a crawl. The top command show 40 or so oracle processes like this:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
19774 oracle 16 0 666m 24m 22m R 4.8 1.2 0:04.94 oracle
Each process is grabbing 666m of virtual memory. I have the SGA and other memory parameers sized at:
test.__db_cache_size=452984832
test.__java_pool_size=4194304
test.__large_pool_size=4194304
test.pga_aggregate_target=201326592
test.__shared_pool_size=142606336
sga_target=605028352
The "free" command shows:
total used free shared buffers cached
Mem: 2076488 1937468 139020 0 212308 832272
-/+ buffers/cache: 892888 1183600
Swap: 9767512 12476 9755036
The "vmstat" command shows:
oracle@hans:~$ vmstat

Do i simply need to reduce my SGA or add ram to my db server? My database tuning skills are beginner. I can't tell if this is happening because of runaway sql statements or because my oracle memory parameters need tweaking. Can anyone point me in the righ direction to reduce the memory swap? I don't know why each process is grabbing 666m of memory. When i query v$sql and v$session i see only 15 sql statement running and these queries run fine in other environments. The only parameter i recently changed was the processes and sessions parameters. I bumped it from 150 to 500 but we control this number on the app server and there are only 122 sessions currently running. I need some general advise on controlling memory allocation.
Any advise would be greatly appreciated.
Thanks,
Dave

In fact, the process at O.S. level is not in v$session.process (thank Oracle for that one!). It's in SPID column of v$process. The link between v$session and v$process is the process address (v$session.paddr=v$process=addr):
SQL>select sid, serial#, process, (select spid from v$process p where p.addr = s.paddr) from v$session s where sid = 821;

Cannot create virtual memory swap file - when retrieve workbook

We are running Discoverer 4i on Window NT Terminal Version. System will prompt this problem 'Cannot create virtual memory swap file' when user tries to retrieve a workbook. The workbook has complex queries.
However, we have as much as 3GB available spaces.
Please help, for those who know the solution.
Thanks.

I don't think terminal server is a supported version
of windows for Discoverer.

I can't Disable my Memory Swapping on mac ( launchctl: Couldn't stat("/System/Library/LaunchDaemons/com.apple.dynamic_pager.plist"): No such file or directory nothing found to unload )

Hi Guys! I really need help here, Im a Web Graphic Designer and i really use alot of Memory on my mac ( i have 8gb ram ). Everyone told me that disabling the memory swapping would really help alot and tried to disable it. All of my friends taught me on how to disable it by enerting
" sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist " on my Terminal
It really works on other MacBPro but i ge this error message
" launchctl: Couldn't stat("/System/Library/LaunchDaemons/com.apple.dynamic_pager.plist"): No such file or directory nothing found to unload "
I tried to look at the folder or directory there is no com.apple.dynamic_pager.plist and its confusing me cause the memory swapping is still working without the com.apple.dynamic_pager.plist.
Can someone help or tell me how to fix this? I would really much appreciate it.

I never heard of anyone doing what you are attempting!
If you have so much memory as you claim I don't see the advantage of running the system in this non-standard way since you probably won't need to write to a swapfile anyway. And you are asking for trouble if it does need it and it's not there.
Finally, I submit you must have missed or or looked in the wrong place. In terminal cut/paste the following:
ls /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist
It shouldn't report an error.

Yes that is a "default" answer to upgrade to the latest patch set. You should do so because in most cases it helps.

Increase memory, swap slice change

Sorry but it's solaris 8 on a SPARC not solaris 9 but there doesn't seem to be a forum for it.
I've installed an ectra 512MB of memory into my server (increasing it to 1024MB). The installation of solaris 8 was always set to use 512MB. I increased the swap slice to 1.5GB (see the entry below) :
3 swap wu 6242 - 9362 1.50GB (3121/0/0) 3145968
My vfstab looks like this (I haven't changed anything yet) :
fd - /dev/fd fd - no -
/proc - /proc proc - no -
/dev/dsk/c0t0d0s3 - - swap - no -
/dev/dsk/c0t0d0s0 /dev/rdsk/c0t0d0s0 / ufs 1 no -

swap - /tmp tmpfs - yes size=512m
Do I need to change the swap line or change anything else for solaris to first of all use the new memory and second of all use the larger swap file?
TIA

Okey doke,
swap -s reveals :
total: 156232k bytes allocated + 24848k reserved = 181080k used, 2181664k available
swap -l reveals :
swapfile dev swaplo blocks free
/dev/dsk/c0t0d0s3 136,3 16 3145952 3145952
df -k reveals :
swap 2179672 24 2179648 1% /var/run
swap 524288 8 524280 1% /tmp
so I suppose my new swap partition is in use ? Is this right?

2010/2011 Memory Swap?

I have a mid 2010 Mac mini connected to my TV for use primarily for Internet radio and video and I also recently bought a mid 2011 Mac mini to replace my 2007 iMac after its LCD panel went south. The 2011 system report shows 1333 MHz DDR3 memory whereas the 2010 shows 1067 MHz DDR3 memory. I am thinking to upgrade the 2011 from 4 GB to 8 GB and swap out the 2 GB in the 2010 for the 4 GB from the 2011. Will the 1333 MHz DDR3 memory from the 2011 work in the 2010?

I theory it should work. However, there were instances
in the past where older systems did not work with faster
memory. Every memory board has a small PROM on
it that gets read at boot time which identifies the memory
and its characteristics so that the uP can configure its
bus. If the specs it gets doesn't match what its firmware
says is compatible it will not boot. Whether this is still
true on recent Mac products I'm not sure.
However, the worst that could happen is that your 2010
just won't run with the faster, bigger RAM.
I recall an issue a few years ago where a vendor had built
DIMMs with a particular ID PROM and did speed screening
on assembled DIMMs. Those that didn't meet the higher
speed spec were just labeled as a lower speed device. The
results were that some system didn't work with it.

Cannot create virtual memory swap file

Hello,
I'm getting an error message when i execute the query of a workbook.
The message I receive is "Cannot create virtual memory swapfile "\EuZ""
Something to note is that my workbook opened and ran fine in the morning and started crashing in the afternoon.
I started the workbook on another user's machine
and works fine... for now.
I look in the .INI that are created when i open discoverer and found nothing.
If there is a setting to change or
someone knows about that problem, let me know.
NOTE: The version i'm running is dicoverer 9.0.2.39.01
under windows 2000 (SP3)
Thank you
Yan

This is a (sometimes) bug, at least in Discoverer 3.1 and I see it on some machines when I first install Discoverer. One or two queries may work, and then your message (with garbage characters for the "file name") from then on.
The program seems to fail to correctly set the cache sizes in the registry (or ini file or whatever it's saving stuff) from the Preferences.
What fixes it for us (every time) is:
1. Pull down the [Tools] menu.
2. Select [Options].
3. (Scroll right if needed to) select the [Cache] tab.
4. Set the [Memory Cache] and [Disk Cache] values. You can set them to the values they were going to default to anyway, just type in there and then put it back to the original value so it sees they were "modified" and saves the values when you...
5. click [OK]
Apparently the installation defaults are not reliably saved in the first place. "Changing" them in the [Options] dialog will, however, reliably set them and that always cures this problem for our users.

Thanks.SWAP is an OS operation & Oracle has NO knowledge about it.
OS moves "idle" processes to free up RAM.

Memory usage problem on AIX 7.1

Hi,
We are running Oracle 11GR2 EE on AIX 7.1 and keep getting alerts on the pgchecks (memory paging).
The alerts are coming from another system monitoring tool (Hobbit), but our sys admins are telling us it is because we are overallocating memory.
In our case, we have an 8G SGA for the only database.
Then, we are running grid and ASM.
How can I check the actual (real) memory usage by individual processes of our Oracle database, our emagent (OMS agent), and for our ASM. In our case, we have 32G of Real Memory installed, and we should not be having a memory paging issue.
For the Oracle database, it is set for 8G.

Changing swap file location on tray-loader iMacs

This is not a question, but something I discovered that makes my old tray-loader iMac (the oldest iMac models) run Mac OS X much better.
As you may know, these oldest iMacs have an 8GB size limit on the boot volume. The largest stock drive on these iMacs was 6GB. That means if your upgraded hard drive is larger than 8GB, it must be partition so that the first partition is under 8GB (7.78GB on my iMac), and it must be the boot partition where the OS is installed (whether it's Mac OS X or 9).
In my case, I have a roomy 120GB hard drive (I believe the useable limit on these iMacs is 128GB). The first partition is just under 8GB, the second partition is the rest of the space, about 104GB. I have used every trick out there to move files (such as the iTunes music folder and most of my user/documents files) off to the second partition, to make free space on the boot partition as large as possible. So I have 3.5GB free on my 8GB boot partition. This is about 40% of the volume's total space so it seems pretty good, until you realize that most recent Macs have much more than the TOTAL 8GB I have, as free space on the boot volume. Mac OS X was just not designed to work well with small boot volumes...
Mac OS X uses the free space on the boot volume for its virtual memory "swap file." Considering these old iMacs max out at 512MB of RAM, virtual memory is being used quite a bit. But since space on the boot volume is very limited, low RAM and lack of free space can lead to performance issues. Here's what I observed. When I initially started up my iMac, I had about 3.5GB of free space. Over time, as I used more and more apps, that free space would diminish until I had only about 600MB remaining (as reported by a Finder window). At the same time, I noticed performance getting bogged down and more "chugging" sounds coming from the hard-working hard drive.
I've known about changing location of the swap file, but never tried it until recently. During the Mac OS X boot process, the Mac sets the location of the swap file. By default, the swap file resides on the boot volume (I believe most other Unix-based systems use a dedicated "swap partition" for the swap file). Since most recent Macs have large drives set up as one partition (and there is plenty of free space), and since many users have upgraded their RAM (and virtual memory is not as critical), swap file location is usually not an issue, and there is certainly no need to change the swap file location. However, on my iMac with an 8GB limit on the boot volume and 512MB of RAM, it made a noticeable difference.
I found one set of procedures on the web that was much better than the others I found for changing the location of the swap file.

On this page, there are two choices for Panther users. I used the one that works for both Panther and Tiger, because it appeared to me to be more straightforward. The author intentionally keeps the instructions somewhat technical to discourage users who are not technically inclined. I don't consider myself to be too "geeky," but I can follow instructions and type a few commands in Terminal.
After I changed the swap file location to a large mostly empty volume, I noticed much better performance when I have many large apps open at the same time. Performance no longer degrades over time, and the free space on my boot volume remains a constant 3.6GB.
The reason for this post is to share this information. Some users of these old iMacs may be noticing the same issues I had. This is a possible solution. However, if everything is OK with your set up, there is no reason to change the swap file location. If you try it, be sure to take the usual data backup precautions.
If anyone else has experience with changing swap file location, please post your comments here.

Startup Disk Memory Inexplicably Low/Missing

I normally keep a close eye on the amount of info going into my partitioned Mac HD (presently: capacity 29.88 GB, 27.64 Used, 2.23 Available), but I received a message today to the effect that "your startup disk is low in available memory..." while only running Safari... The last time I had checked (about 1 month ago) I had between 9 and 10 GB of available space, so needless to say I was rather surprised to get this message. I immediately did a "Get Info" on the drive and was SHOCKED for TWO reasons! 1) that the available memory was so low... but ALSO as I checked and RE-checked the memory was DISAPPEARING before my eyes! I was only running Safari (although a couple hours prior I had worked on and saved a 5+ page site in iWeb with a fair amount of imagery... I have 1 GB of RAM. I restarted and the drive has since stabalized at 2.22-2.23 GB Available. I restarted in Safe Mode and restarted again and ran a repair permissions on it. All seems to be ok for now BUT I haven't reopened iWeb for fear that that may be eating up what little memory is left AND then there is this OTHER issue of where these other 8 or so GB have gone to???? When I calculate Finder items in the HD they total 19.5 GB not the 27.64 that "Get Info" pulls up for it. One more note: I installed iLife '06 about a month ago... What is happening here?
PowerBook G4 17" Mac OS X (10.4.5)

Hi, O.
1. IMO, with only 2-3 GB of available (free) space, you're critically short of free disk space. Cache files and virtual memory swap files could readily and quickly consume that. See my "Problems from insufficient RAM and free hard disk space" FAQ.
2. A runaway process constantly writing to log files can chew up disk space. Check these Console logs for clues, specifically large blocks of repeating messages that recur at high-frequency. If you find such blocks, post some samples for diagnosis. Again, do not post the entire log or logs, just copy/paste samples of blocks of repeating messages that recur at high frequency.
Common causes of runaway processes writing to logs include software associated with Canon and HP scanners, software for HP All-In-One devices, and Adobe Acrobat version 7.x prior to version 7.0.5. Depending on the messages you post, I can give you specific actions to take if one of those apply.
3. See also my "Freeing Space on your Mac OS X startup disk" FAQ.
Good luck!

Acrobat 9 Pro a memory Hog

I have a 175kb 2 page PDF file that I am updating a field in. On save, memory usage soars from about 300MB to well over 2GB causing massive memory swapping on my laptop which is configured with only 1GB of memory. I have trimmed down all necessary processes and this still happens and only when I try saving under Acrobet 9 Pro so I am pointing my finger at it. I am using a trial version of it which I am very happy about since I would not want to purchase this product if I can not save files. I have a Dell Latitude D520 with Intel Core Duo 1.66GHz CPU, 1GB memory running Windows XP Pro.

> I am pointing my finger at it.
I see you aren't looking specifically at memory usage for Acrobat. You
can do this with Task Manager - the Mem Usage column in processes is
virtual memory (not RAM).
I wouldn't be the least bit surprised to see Acrobat doing this, but
still, it's worth checking.

Potential memory leak in 11.2.0.1.0 cluster stack components

Hi All,
We are running 11.2.0.1.0 RAC on OEL 5.5 and OEL 5.5. On all of our boxes, we have observed a gradual increase and filling of swap space. Swap usage slowly but steadily increase to a point where either the Node boots automatically or we have to manually restart it.
To get more insight into the issues, we recently upgraded one of the nodes to Oracle unbreakable kernel and installed smem to profile the memory consumption pattern. smem will give the process set size (RSS), the unique set size (USS) and the proportional set size (PSS) which is the unique set size plus a portion of the shared memory that is being used by this process.
It appears that there is a gradual increase in memory/swap consumption of some clusterware components. Also the weird part is that the process is filling up the swap space and not utilizing the unallocated RAM.

Thanks for pointing to MOS notes, they were quite helpful. Though sometime on our system, ohasd.bin consumes more resources. Is it safe to kill it?
Also, we have observed that there are multiple oraagents belonging to different users such as root,grid and oracle.
grid 14620 1 0 20:32 ? 00:00:14 /u01/app/11.2.0/grid/bin/oraagent.bin
root 14625 1 0 20:32 ? 00:00:02 /u01/app/11.2.0/grid/bin/orarootagent.bin
root 14627 1 0 20:32 ? 00:00:00 /u01/app/11.2.0/grid/bin/cssdagent
grid 14803 1 0 20:32 ? 00:00:06 /u01/app/11.2.0/grid/bin/oraagent.bin
oracle 14807 1 0 20:32 ? 00:01:53 /u01/app/11.2.0/grid/bin/oraagent.bin
root 14811 1 0 20:32 ? 00:00:38 /u01/app/11.2.0/grid/bin/orarootagent.bin
When these are killed, not all are re-spawned automatically - typically oraagent belonging to "oracle" user is left out. Is this an expected behaviour or it will cause some instability in the clusterware?
Thanks
