Safe to run a program 24-7?

I have a MacBook Pro that I am going to use to show a video at an art exhibition. The exhibition runs one month. Will it hurt the laptop to run the program 24-7, that is, continuously? The video will be showing on a monitor and the laptop will be housed in a locked shelf under the monitor (it will have ventilation) since it is in a public venue. The issue is that I will not be able to turn it on and off each day (the monitor will be shut off and on each day) and no one else will either. I know that leaving a computer on is no problem- but is running a program for a month harmful to the computer?
thanks! Frank

In addition to what OGELTHORPE said, I would be especially leery of "ventilation" in a locked shelf. A few holes drilled in the back, for example, probably won't do the trick. Forced air (i.e., a shelf with an exhaust fan and air intake vents) would be a lot better.

Safe to run music production programs via vm fusion?

Hello hello,
I have been running a windows-only music production progam via bootcamp for a couple months, but I'm frankly tired of having to reboot all the dang time and I'm worried frequent restarts is not healthy for the computer. So, I want to try vm fusion to run this program on windows concurrently with whatever else I'm running on osx. However, because music produciton programs tend to suck up a lot of the cup power...is this a good idea, given the fact that vm fusion will essentially allocate one core to windows and the other to osx? Or do I have the wrong idea of how cpu is allocated via vm fusion?
I'm using the 2.7 Ghz dual-core i7 mac book pro (early 2011 model). The music program I mentioned is FL Studio 9 XL Producers Edition.
Thanks for any help in this confusing topic : )

Try it. Seeing as you already have Windows installed using Boot Camp, just download the free trial of Fusion and tell it to use your Boot Camp installation of Windows as the target OS. You don't even have to re-install Windows.
If it works for you buy the license and continue using it. If it does not work for you don't buy the kicense and uninstall Fusion. You don't have to change anything with respect to your Boot Camp installation.

I have a Macbook Pro 15" that is three and a half years old. Although it has slowed a bit, it still runs well and runs every program I need. Any tips for how to keep this old computer running well and in good health?

I have a 250 gig drive and try to keep at least 100 gigs unused at all times, 4 GB 667 MHz DDR2 SDRAM memory, back up with Time Machine and CrashPlan, and have OS X 10.7.3.
This was my first Mac since an old Apple II GS. After that I used PC's and got really good at reformatting, replacing drives, reinstalling, defragging, resolving software conflicts, etc. Since switching back to Macs (five in my extended family now), I haven't had to do any of those things. So, although, the cost is three times as much, the aggrevation has been ten times less.
I'm retired and living on a fixed income and would therefore like to keep this computer running as opposed to constatntly upgrading.
That said, any tips?
Thanks
It does have a crack on the left of the screen case about 3/4'' up from the bottom. I've posted that as another question.

Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Adding more RAM, if feasible, and a new, faster hard drive may also help pep it up a little.

I dont see the "edit options" button thats suppose to be on the top right hand corner. I need to download and run a program and I need to click that to do it, what do I do ?

Or how do I download a tool bar for firefox, or run a program like you do for internet explorer?

/SAPAPO/SDRQCR21 program is not working correctly if we run the program for range of material and plant wise

Hi APO Experts,
In our project, we have received more sales order inconsistencies which is not clearing by CCR program and it is clearing by program /SAPAPO/SDRQCR21 with option as Build Reqmts from Doc. Flow, So We have decided to schedule the background job on daily basis for program /SAPAPO/SDRQCR21 with option as Build Reqmts from Doc. Flow, performing the testing in our quality system and observed the below strange behavior.
When I am running the program /SAPAPO/SDRQCR21 with Range of products and some location range with option as Build Reqmts from Doc. Flow, in Background job. In output it is suggesting to delete one sales order. If I checked that Sales order in ECC, it is for an different location, that is not part of my selection and the order is open. In MD04 the Qty is showing 1 ( as per sales order) but in APO RRP3 view the order qty is showing Zero. I have run the CCR, it is coming in different in content and if I push, the different is not going to APO.
I have tried running the program /SAPAPO/SDRQCR21 with plant which is mentioned in that sales order with option as Build Reqmts from Doc. Flow, in Background job , it is suggesting this sales order under update option correctly.
Can you please help me understand why it is behaving differently like the location is not part of my selection and why it is suggesting the wrong action. And also whether is it advisable to run the /SAPAPO/SDRQCR21 with option as Build Reqmts from Doc. Flow at plant range and material range in background job.
Thanks & Regards,
Sundaram Radhakrishnan

Sundaram,
It sounds to me like the sales document records in the OLTP and in APO were created at different times. This is common in Dev and Qual environments when the systems are commonly created at two different times, and each was a copy of an existing system that contained sales data. The order number you see in //rrp3 is somewhat irrelevant; system generally uses the guid for many activities.
FYI during Dev and Qual refreshes, if you are copying from a production environment that contains data, it is always best to create the OLTP and SCM images at the same time, and to copy them both to the Dev and Qual systems at the same time. If you don't do this, you are faced with the additional tasks associated with getting the copied systems back into synch.
If this is Dev or Qual, I suggest that you just completely wipe out all sales orders in APO and rebuild them using the CIF.
If this is a mature production environment, the only time I have ever seen this issue is due to improperly created CIF enhancements. Speak to your developers to find the root cause, and correct this problem. Then, wipe out all sales orders and rebuild with CIF.
Best Regards,
DB49

Unable to Run C Program using Xcode "Stop Executable"

Hi All
Have been using the Terminal to compile programs built through Xcode but now want to use Xcode itself. Everytime I press build and go it builds successfully but won't run. I found a tutorial that mentioned if you are using Xcode 3.0 (I am) you can't use build and run, for output, you have to go to run and then push console.Ok that works. I then found someone with the same issue as mine everytime you want to build and run it appears with another window saying "Stop Executable"They were told to make sure they were building the .c file in a project and not building it from a text editor and then importing. I always build new projects.
I want to interact with the program not just see its output? so my question is can I interact with programs i.e. User can enter data or strings or, do I have to build an interface to do this through Xcode. I Also forgotten to mention I found information through the forum that said to go to First Aid through utilities and repair file permissions, this has been done but still does not work. Many thanks for your time and as you can probably tell I am new to Xcode.

To run your command-line program in Xcode, open the debugger console by choosing Run > Console. Run your program by choosing Run > Run or Build > Build and Run. You'll have to build and run if you haven't compiled the program before. Your program will run, and you will see output in the console. You interact with the program from the console.
If you're not able to enter input in the console, choose Run > Sync with Debugger. If doing that doesn't work, you can run your program in the Terminal application by double-clicking the program from the Finder. It's less convenient than running it in Xcode, but you'll at least be able to run the program and interact with it.

Problem with running a program under Labview 8.6

Hello,
I am writing you this to ask for your technical support to fix the problem I am facing at our Lab at University of California, Irvine.
Ms. Vanessa Trujillo has kindly come to our lab a couple of times and tried different things to resolve the issue, but unfortunately the issue is not resolved yet. Here is a summary of the problem:
We used to use Labview 6.1 for our fatigue testing and data acquisition.
Our
program worked just fine under the 6.1 version We recently upgraded our software to Labview 8.6. We have also purchased a new computer that has higher capacity than what your website requires for Labview 8.6. The new computer has Windows Vista We transferred our old program/subprograms from the old computer under Labview
6.1 to the new computer with labview 8.6. However our program that worked fine with the 6.1 version is not working with the updated version (ver 8.6).
There
are 6 errors in the error list. It appears there are six files of my program missing under the new version, even though we transferred all files.
The software searches for those files but can't find them.
        For example one the box pops up indicates:
        loading:
                    <vlib>:\Daq\lvdaq.dll
        searching:
                    C:\Program Files\National Instrument\LabVIEW 8.6\instr.lib\Agilent34401\public\utility
        I get several message like this. I have to cancel/ignore them all to be able to open the program.
When we go to VI's under Measurement I/O there is nothing (empty).
We use a PCI-MIO-16XE-50 for our data acquisition During Labview installation on the new computer, I was asked if I wanted to install the device drivers. I had two options, "Now" or "Later", I picked Now but I didn't have the DVD's/CD's for the device drivers. Therefore I had to select later to complete my software installation Later after Labview 8.6 installation, we installed the device drivers (traditional Ni DAQ and Ni DAQmx) from the two old CD's we had in our lab from a couple of years ago (the CD's were Ni DAQ 7). after installation, the PCI board on the computer was recognized by the device driver. However we still could not run our program under the new version of Labview (same situation and the same messages) I called 1-866-275-6964 on 9/2/08 and talked to Grant (service number:
1228841). He recommended that I download and install the updated version of device drivers.
Since I didn't have the DVD/CD for updated device drivers, I contacted Vanessa Trujillo. She gave me the DVD for the updated Ni DAQ (Traditional and mx).
But
when I tried to install the updated device drivers I got a message something like "some unsupported filed have been detected,..." so the updated device
drivers were not installed. It should be noted that up to here we still had the Ni DAQ (traditional and mx) installed on the computer from our old CD's (Ni DAQ 7).
Vanessa and I talked to Tom at the technical support department. He recommended that we download and install the Beta xx version for Ni DAQ since we were using Windows Vista. Mike put the Beta software on the Ni website/outgoing so I could download and install it. He asked me to uninstall the traditional Ni DAQ that we had on our computer from the older CD's. He
asked me not to un-install the Ni DAQmx (that we had installed from the old
CD). I was able to download the Beta software, however I could not install it since I got a similar message that some unsupported files were detected.
Right now we don't have any version of traditional Ni DAQ installed on the
computer but the NI DAQmx (from old Ni DAQ 7) is still installed on the computer. Vanessa let me borrow her new Ni DAQ DVD but as I explained I am not able to install the device drivers.
Vanessa - Did I miss anything?
Please advise. My cell number is 619-778-2033. I will be at our lab at UC,
Irvine at 2:00pm (CA/Pacific time). Please call if you have any questions.
Thank you

To me, it looks like you are missing some of the drivers and subVI's used in your program.
Whatever device you are using to measure fatigue or any other device probably came with a driver.
You need all of these drivers installed on this new computer.
Also, any subVI's and libraries you use in the program must also be installed on the new computer.
Whenever you get a message that says you are missing some component (the ones that you said you press 'ignore'),
see if you can find that library or subVI on the older computer. If so, save it to something so you can transfer them to the new computer.

When I connect an external drive I'd like to run a program which is on it. How could I do that?
I tried automator, but without success.
Thanks

Interesting question. Others have provided the direct answer (no, massive security hole), and a little time with a search engine finds various existing discussions of autorun-related topics (eg: here and here and here), and a link to the Do Something When tool, and there is the DeviceListener example in the Xcode kit and to adding a folder action where the volumes are mounted. See the topics for details. Haven't tried this stuff, though.

Running BDC program in background for the transaction VL02N

Hi All,
I have coded a BDC program (call transaction method) for the transaction code VL02N. I can able to run the program manually & successfully. But if I execute the program in background(SM36), it is going to dump giving CNTL_ERROR.
Note: I am not using any of the GUI_UPLOAD, GUI_DOWNLOAD funciton modules in the program. But I am using the FTP command funtion modules like( FTP_COMMAND, FTP_CONNECT, FTP_DISCONNECT and FTP_SERVER_TO_R/3).

Thanks in advance.

VL02N is an enjoy transaction. You cant run it in background. Please try VL02.

"Error determining planning periods for calendar " when running a program

Hi,
When i am running a program with date range say "01/05/2011" to "30/06/2011",the program is executing successfully without any error. When i am executing the same program with date range as a) "01/05/2009" to "30/06/2011" and b)"01/05/2008" to "30/06/2011" the program is failing with error as "Error determining planning periods for calendar". Can anyone suggest me what i should do to avoid the failure of the program with above date ranges also.
Thanks in advance,

Dear,
Error message 61123:"Error determining planning periods for calendar &".The PPC planning calendar specified in the material master MRP 2 view for the material is incorrectly.
The planning calendar periods are insufficiently maintained for the planning calendar used.
Check the period of planning calendar in MD26 and generate the correct period.You can avoid the problem in several ways:
Maintain the planning calendar far enough in the future (at least until beyond the end of the planning horizon).
Also check any demand is lies beyond the validity period of planning calendar.
Reduction of the planning horizon of MRP also can control such issue, as MRP planning horizon lies in an area in which the planning calendar is no longer maintained

Say name of the java file is newFile (no packages).
When i try to run the program by using java newFile it raises a ClassNotFoundException.
it s the same case when try to set any JDBC drivers ..
is there any problem in my class path settings? Please help me out to fix this problem

if your current directory is not in the classpath,you should include it in the classpath.
To do that you can include .(dot) to your classpath variable.
