Forcing an application to load and run from memory

Greetings,
Is it possible to force an application to load and run only in RAM? I've got a V60 (i386) with 4gb of RAM running Solaris 10 (beta). We have an application that we would like to ensure loads and runs only in RAM and not swap to the disk. The machine is used for this one application that uses about 50% of one CPU at all times. Even with this application running, of the 4gb of RAM, 3.5gb are unused.
The swap size is equal to the size of the RAM, but we want to prevent the application from ever using swap. Is that possible?
Thanks,
Bob

Unless there is memory pressure solaris kernel does not throw away a process' pages onto swap.
When you have 3.5Gb of unused main memory, there is no chance for this application pages to be
put on swap.
You can use 'pmap -x' to check RSS matches the process size.
'swap -s' tells you how much swap is actually used.

How do I load and run a sequence from the Tools menu?

If I can build a sequence to do something special, what's the syntax required to load and run it from a menu? This must be transparent to the customer. I know how to add menu items, but the tools customize window seems to be looking for an exe.

When you go to tools>>customise and then add in an item to appear in a menu, you need to select sequence, rather than command.
Hope that helps

Mail Slow to Load and Running Slowly

Yesterday, I tried to copy a block of text from Sarari over to an email. Something I have done many times, but this time, Mail hung up with the spinning beachball and I eventually had to force quit Mail. Since that time Mail has taken minutes to load and runs slowly. I have trashed caches, repaired permissions and repaired the disk. Talked to Apple Support for 30 minutes or so this morning and tried all the stuff they suggested.
Now Apple Support is suggesting archive and reinstall.
My questions are:
1. Does anyone here have an idea to try?
2. Any thing to look out for on archive and reinstall if it comes to that?
Thanks,
Bob Crites

As a more convenient alternative to a full Archive and Install, you may try reinstalling just the Combo Update for the type of computer and the version of Mac OS X you’re using, unless this is the version of Mac OS X that came with the computer:
About the Mac OS X 10.4.8 Combo Update
Mac OS X 10.4.8 Combo Update for PPC
Mac OS X 10.4.8 Combo Update for Intel
Take a look at the following articles for guidelines on how to properly install system updates:
Troubleshooting installation and software updates
Installing software updates
Basically, you should verify/repair the startup disk before installing the update, no applications should be running while installing it, and you may experience unexpected results if you have third-party system software modifications (not normal applications) installed.

Can CC apps be downloaded to, and run from, a hard drive other than the OS drive?

Yes. You can define alternate locations in teh application manager. just be aware that some components will always end up on your system root drive no matter what.

OS is loaded and running but screen freezes on the loading screen

My laptop is freezeing on the loading screen but the os is loaded and running. I know this because i was able to use command keys to open itunes and play music. At first i thought it was the hard drive so i replaced it and i am still having the same problems. I'm stumped, can anyone help me?
Some one please help?

"The gray boot screen with the apple and the loading ring."
"i was able to use command keys to open itunes and play music."
You could do that from the "gray boot screen?" Didn't know that was even possible!
Disconnect all devices from your computer and do the following:
Boot up from your install DVD and run *"Repair Disk"* from the Utility menu. If you are able to reach the desktop after doing the above, repair permissions and restart your computer afterwards.

Can someone pls. Tell me how long it would take to have the iPad up and running from removing the plastic on the box?

Can someone pls. Tell me how long it would take to have the iPad up and running from removing the plastic on the box?

Upon applying for Telstra contract, salesman filled out all details & I was approved immed. He grabbed a new iPad 2 from the store's stock, all plastic wrapped, a white 32 gb. He then asked me if I needed to go and do some shopping as he had mucked something up and had to redo application. Everything had been completed and approved on screen, so I wasn't sure why he had asked me to come back in half an hour. I did so, and upon arriving back he was standing at the desk, iPad in hand together with receipt and box, no evidence of shrink wrap. As I already had bought a red cover, he basically grabbed that and slipped the iPad straight into it, without really asking me, and said, all ready to go. Was a bit surprised but accepted that. Did not see it being unwrapped, sim inserted or anything. Thought it to be odd, and without any further advice, was handed bag, box and receipt. Got home, thought it looked a bit fingerprinty, then wondered why it was basically set up ready to go. He knew I was a gadget freak, owning 25 wifi related devices, but had never bought apple products so he said I'd have no problems. There was virtually no set up to go through except for asking if I had an apple ID which I didn't so I created that and away I went. I was looking through the settings a bit later and noticed the ITunes said to sync back with WILLS-MSI when it was available. WILLS is the name of the store. There was a 32 gb white iPad 2 as a display model and now I am seriously wondering if he has taken that off the shelf and given to me. I have never in my life bought a display model and never would. From my description do you think I may be right? ( even the silver back looked 'not quite new').
OPINIONS appreciated, is there anyway of checking to see if a reset has been done as I am not at all happy & will be going straight to store manager on opening of store.

Can OS be installed and run from a Firewire drive?

Hello,
I recently started to switch from WindowsXP to a Mac Mini. I was considering installing WindowsXP to a drive that I put into my AMS Venus 3.5" drive enclosure. This is a combination enclosure that supports USB 2.0 and Firewire 400. I've never used a Firewire device before so I don't know how well XP would install to and run from a Firewire drive. I'd like to setup XP to run underr Parallels. Its a Seageate 160gig 7200rpm drive that's about 1 1/2 years old.
Is this possible? Is is actually usable going through a Firewire connection?
Thanks,
Jeff

Hi Jeff,
installing Windows under Parallels will produce two files that contain the Windows System itself (filename.hdd) and the configuration file (filename.pvs).
These two files can indeed be put onto an external harddisk and run from it.
It is quite usuable and you should get the same 'speed' as if these files where on your internal HD.
Have a look at the PDF files here http://www.parallels.com/en/products/desktop/ for further information on how-to.
Have Fun

How to Enable Plugin before File Opened And Load PDF File From memory?

hello everyone,
there have two problems,all i want to do is to show a pdf file encrypted by AES algorithm.
1.one is how to enable plugin before file opened?
i developed another two plugin,and each enabled after one pdf file was opened,and now i want to replace the file open command and can do some word by meself,such as decrypt the pdf ?
2.another is how to load pdf file from memory?
if i can enable plugin before file opened,and than i can read the file and decrypt it,and now i want to do is do load the decrypt file (in memory) into the adobe?
i tried many method,but all in vain.who can help me or give me some advice?
thanks.
merry chrismas to everyone.

The proper way to handle other file formats (even where it is really a PDF that has been "wrapped") is to create an AVConversionHandler.
To load a PDF from a source other than the file system, you need to create a custom AVFileSys.

Compile and Run From Windows Cmd Line?

VI on LabVIEW real-time is loading and running a DLL which has been deleted from the machine

OK, this is a weird one (at least, to me :-) )
I have a small real-time demo application VI that I am writing, using some new VIs I just created. My new VIs are wrapper functions for a DLL, using Call Library Function Nodes.
In the process of debugging, I decided to delete the DLL and run without it, to confirm that I am actually loading and using the DLL (since it seemed to have stopped doing something it had successfully done just a little while earlier).
The VIs that use that DLL still run, and at least some of them actually do what they are supposed to do. But the DLL does not exist on the real time machine! Not only did I delete it, reboot the machine, and check that it was gone, but through my ftp program I searched the whole hard drive for that DLL and did not find it (the search succeeded in finding a different DLL which did exist on the system, so the search-via-ftp is working).
How could this happen? What am I missing? Could this somehow be the result of a corrupted VI or is there some more logical explanation for the phenomenon?
Thank you.
Batya

Nathan is right at least for the Phrlap ETS based RT systems. For VxWorks you have to (or maybe used to have) to download the shared library to the controller before you could deploy an executable that makes use of them. For Pharlap ETS systems if you deploy a VI library dynamically to a machine it will download everything including shared libraries to the the RT target memory and run it from there. Only if you create an executabel and "install" it to the target and run it from there will it use whatever VIs are in the executable and also use the shared libraries that have been installed onto that system (at least for Pharlap ETS RT targets. As mentioned before for VxWorks targets, the deploy process even for executable installation did for some reasons not take care about moving the according *.out library to the target together with the rtexe).

0MAT_PLANT load is running from a ling time

Hi All,
I have triggered a 0MAT_PLANT info package. It is running from last 2 hours with same number of records.
No of records is not increasing.
Please let me know the reason and solution.
Thanks in advance.

Hi,
Chk the extraction job in source system whether it is finished...?
Go via environment>job overview>in the sourcesystem....with logon details and chk the log whether it is finished....?
Chk the log clearly such that the idoc generation is increasing or not?
I guess the extraction might be finished only BI system is waiting for the confirmation from source to finish the load...wait for some ore time...
Ch in monitor details tab whether ur data extraction,transfer and processing finished or not?
If it is finished then goto SM58 of R/3 and chk for idoc's...if there manuallly push by selecting each and click F6...
rgds,

Java application behaving differently when run from netbeans

Hi,
When i run my program from netbeans it receives packets from ip addresses which are not in my subnet
but when i run it from outside netbeans it doesn't receives packets from ip addresses which are not in my subnet.
Can anybody explains why my application is showing different behavior when run from netbeans and when run independently?
Thanks.

Bingo! My script started the rmiregistry and continued on to start the servers. Apparently, it was too quick. I put a 10 second delay after the rmiregistry startup and all is working as it should.
Thanks for your help. You get the Duke dollars if I can figure out how that works.

Mac SE FDHD with dead HDD - boot and run from floppy drive alone? HDD type?

Hello!
I picked up a Mac SE FDHD a few months back - a model with a Superdrive and hard drive, as well as 4 MB of RAM. It came with a keyboard and mouse, but no floppies of any kind. Upon testing, I discovered that the hard drive did not work - the "flashing question mark folder" appears at startup, and the disk setup utility on the system 6 install disks I created using a more modern mac can't detect it. I don't hear HDD seek sounds either. Everything else works fine, as far as I can tell. The reason I want to use this old Mac is simply to boot it up and run a few favorite old programs (such as MacPaint and many old games), so I don't want to put too much money into it.
I discovered my parents still owned a old, 170 MB "LaCie Tsunami" SCSI external drive, used with our long-failed Mac II, and decided to use as the SE's boot drive, as a cheap workaround to avoid buying a "new" drive. However, after a rather odd turn of events (described below for information purposes), it turns out that the 50-pin SCSI drive itself functions, but in the process, I think I killed the enclosure. Unless this drive can replace the internal drive of the SE, (or get lucky and find a compatible drive somewhere), I'll need to run the SE from its single floppy drive.
I figure that since the original Mac had 128k of memory, a single 800k floppy, and no hard drive, and yet can still run OS 7, the SE should be able to run system 6 from floppies somehow. The question is how? Is there a tutorial online somewhere on how to set this up?
Furthermore, as far as the hard drive is concerned, is the SE's internal drive a standard 50 pin SCSI HDD, and thus likely compatible with the one from the LaCie?
Thanks for any suggestions, and for helping this "Old time Mac Newbie" out!
-Dan
PS: What happened to the LaCie drive - for information purposes:
WHen I attached to the LaCie drive to the SE and booted the OS 6 install disks, t worked - OS 6 installed to it just fine. However, it turns out that a "dormant" copy of Norton utilities reactivated when I booted to the SCSI drive, and encrypted the disk's partition table. (Why it was not encrypted BEFORE installing and booting OS 6, I don't know) Having not used the drive for 17 years , and thus not knowing the password, I had to reformat it. I have a Sawtooth G4 with an Apple SCSI card - but no cable that would go from the PCI card's SCSI port to the external enclosure. THus, I removed the drive from the enclosure, mounted it in the G4 internally, and formatted it as Mac OS Standard (with OS 9 drivers) using Mac OS 10.3. Upon re-installing the drive in its SCSI enclosure, I found that it no longer works - Norton was erased, but the SE gives me a "Sad Mac" icon upon boot. Furthermore, after borrowing the correct SCSI cable, I found the enclosure now kernel panics my G4 when attached. The drive itself, when mounted internally in the G4, still functions perfectly. Thus, it seems that either the enclosure is dead, or something about OS X's reformat is renders the HDD incompatible with the enclosure...

"I removed the drive from the enclosure, mounted it in the G4 internally, and formatted it as Mac OS Standard (with OS 9 drivers) using Mac OS 10.3."
I just re-checked Disk Utility's format options under Panther and only see "Mac OS Extended (Journaled)" or "Mac OS Extended." I don't see an option for formatting Mac OS Standard. Are you certain that you formatted the drive as a Mac OS Standard (HFS) volume? If it's a Mac OS Extended (HFS+) volume, that would explain why it won't work when connected to the SE. When using external SCSI enclosures having a hard drive or optical drive, I always opted to connect an "active" SCSI terminator to the unused SCSI port on the enclosure. It seemed to provide stability, because I never had a problem with any of them. Does the LaCie enclosure have a built-in termination switch or do you plug in a terminator to the opposite SCSI port on the back? As for installing/using the 170 MB hard drive in the SE, it must have a jumper installed on its TE pins, if it's the last device connected to the SE's SCSI ribbon cable. Additionally, the HDD must have a unique SCSI address, The factory default is usually 0, which doesn't necessarily require a jumper. If another address is desired, a jumper or two installed across specific pins will accomplish that. If the LaCie enclosure had a switchable SCSI address button on the back (you change it by pressing in with a ball point pen), there were small wires from it that were connected to the drive's address pins in a specific way. Did you disconnect/re-connect these when you re-installed the drive in the enclosure? Also, if the enclosure has a termination switch, did you re-connect its wires to the drive's TE pins?
