Office 2001/Dynamic Memory?

Do the programs in Office 2001 have Dynamic Memory while using OS 9.2?

Hi, HappyWarlock -
Welcome to Apple's Discussions.
Do the programs in Office 2001 have Dynamic Memory while using OS 9.2?
Probably not. I don't use Office, but the vast majority of programs in OS 9 do not have the ability to use dynamic memory allocation; a couple of exceptions are the OS itself (Finder), and SimpleText.
You can change the allocation for the programs in Office manually; the number to change is the Preferred allocation amount.

Running Microsoft Office 2001 with Tiger vs Classic

Mac experts,
Okay, I have a couple of questions. First, I recently installed Tiger 10.4 on my G3 laptop. Runs great eventhough I know I'm pushing the envelope with only 128 MB of memory and at 400 MHz speed. Anyhow, since I also run several programs that required the Classic environment, I went ahead and installed 9.2.2 as well. Both systems seem to work well with each other. I then decided to update to Microsoft Office 2001 which went smoothly as well. The problem (and maybe it's not a problem) is only Classic will run Office eventhough Tiger will run Office for me on my iMac (G4). Is there a way to tell my little ole G3 laptop to run Office from Tiger instead of Classic. I have encounter some freez-ups when working in Office (just Word so far). I would be working and periodically hit save to save the work and several times, when save was hit the machinge would freeze up and require me to do a force quit. Anyhow, any help you guys can give me is greatly appreciated.
Second question. I take a lot of pictures and use iLife to make slide shows and movies. My iMAc has only a 20 GB harddrive so as you can imagine it fills up rather quickly. I purchased a 300 GB external harddrive to store all of my "productions" but was wondering if there is a way to automatically save photos in iphoto and music in itunes directly to the external harddrive instead of periodically making the transfer manually?
Thanks guys for all your help!
Mark

You need Office X or Office 2004 to run it natively in Mac OS X.
As for iTunes/iPhoto you can set where documents are stored in the preferences section of each application.

Word (Office 2001) gives Type 2 error at start-up - help needed

Good day - I'm puzzled by a problem I'm unable to resolve. First, Word (part of the Office 2001 suite) suddenly lost it's pull-down menus, including the About tab, and then, upon relaunch, gave me a Type 2 error and refused to start. It first shows the Start-up 'Gallery' scene, and when you try to open an existing document or a new Word document, it then briefly shows the Word template and then crashes with a Type 2 error (I've run this program for years without any major issues). When I couldn't get this resolved after re-starting with a desktop rebuild, I checked the other applications - Entourage, PowerPoint, and Excel, and they all work fine. I trashed the Microsoft prefs - still no change. I removed the fonts - no change. I reloaded the MS Word portion of the Suite - no change. I zapped the PRAM, tested all the system extensions, even replaced the Internet Prefs - no joy. I even went so far as to do a Clean Install of new System software from my software install disk. Other than this, I haven't loaded any new software or done anything that I can think would cause this, and the odd thing is that the program installed on the hard disk WILL RUN when I boot from a restore or Norton system CD! Yet, when I reboot into my system on the hard drive, I'm back to the error message. With brand new system software the application will crash as before. Short of completing re-installing the Office 2001 suite (which I don't want to do, as I will likely lose all my email and address book and calendar) or re-initializing the hard drive and completely starting over, losing everything, I'm at a loss. I have run Norton (de-fragged the HD, ran anti-virus, etc.), checked my hardware with the hardware test disk, used Disk First Aid, all to no avail - no problems with memory, hardware or software indicated. The only thing I haven't done is update drivers, primarily because I have a newer (3.2.8) disk driver on the system than the Driver Utility has, and I don't want to replace it with 3.2.7. Does anyone have any ideas as to what may be causing this, or have any ideas before I'm forced to take this to a Mac repair facility? Thanks in advance...

Greetings to all - Thank you for your replies and help. I did this in reverse order to the posts. Trashing the ASLM, Finder, Mac OS and System Prefs provided the same result - Type 2 error at Word start-up. I had tested extensions using the extensions manager in sets of 5 with no change previously; I restarted with all extensions off (shift key at start-up) and got the same Type 2 error when launching MS Word.
Further info: I've tried this with VM at 1M + installed memory and with VW at double installed memory and it made no difference (I've always used VM in substantial blocks, even with VPC, which I use daily). I've removed ATM 4.6 as a precaution. I've also tried to remove everything that interfaces with MS Word - PrinToPDF comes to mind, as well as all non-original fonts.
I'm puzzled by one thing, which may be nothing but a curiosity, and it may have to do with the way I'm installing MS Word in an attempt to overcome this issue. As you know, Office 2001 provides you with a number which you need to retain upon installation. My original number, then, becomes superceded with each install; in other words, the last 4 numbers changes, out of the original 54092-XXX-XXXXXXX-XXXXX number provided. A number shows up on the initial lauch window; the problem I detect is that this number isn't the number given at the last install, but the ORIGINAL number I was given when the program was originally installed. This 'suggests' that perhaps the problem is with MS Word itself, as you'd think the program at lauch would recognize the new ID number given when the program files are re-installed using custom install. As an aside, I originally tried to do a 'drag and drop install of the Office 2001 folder, as suggested on the install disk; the system read the item numbers and gave me a 'preparing to copy' message and a spinning beach ball for 20 minutes before I was more or less forced to restart the computer with the reset button. I'm unsure this makes any difference, given that the program will launch with a boot disk, and all of the other modules will launch as they always have.
I'm appreciative of your help and comments. I didn't realize that this forum existed before, having been using a local MUG forum exclusively, and I suspect I'll use it a lot in the coming months as I coax an aging machine to continue working. This may be the first time in 20 years of Mac ownership that a technician might be called for, but I'm hoping for an easier solution.

Problem in dynamic memory allocation

Hi,
My name is Ravi Kumar. I'm working on a project to improve organizational performance which include visual studio for simulation. I'm using dynamic memory allocation to allocate space for the array that are used in the program. Now I have run-time error
which I can't understand where it is going wrong. Can someone please help me regrading this issue.
If anyone interested in helping please leave a comment with your email id so that I will share the whole project folder.

Installing Office 2001 for Mac on new Mac Mini

I own a copy of Office for Mac 2001 that was used on my older iMac.
I thought I could install this on my new Mac mini with OS X. However, after attempting to install from my CD I get an error message saying it is not compatible on the system.
Does anyone out there know if you can infact use an older version of Office for mac on the new Mac mini's? Or, do I need to purchase the latest and greatest version of Office for my new system?
There's got to be a way... don't want t spend another $600 when I have the older version that works fine.
Thank you!
Mac Mini Mac OS X (10.4.7)

You need to install SheepShaver to use Classic and Classic applications such as Office 2001 on an Intel Mac. The current version of Office will run from Mac OS X, and all of its components except for Virtual PC run in Mac OS X on an Intel Mac.

Office 2001 for Mac

New user, so many questions.....
But to start, Bought a used ibook, after trying open office and not liking it much,m thought I would try to install a copy of office 2001 for mac that I got from a friend.
Tried to install and it says I need to run OS 9....
I don't have that, and this has always run OS X. Do I need to get a copy of OS ( in order to run this program, or is there an update I can download to make this compatible?
Just hate to have to buy another version of office if there is a simpler way to make office 2001 work....
Any help is appreciated.

Possible Issue with Latest Office 2001 Update

In the last few days my MB Air mid-2013 with Mavericks did an Office 2011 update to Version 14.3.9. Today I used it for the first time and Excel crashed each time I tried to use it. To get the job done I had to revert to the earlier build (version 14.3.8) from a backup and that appears to work normally.
I don't know if this is an issue with Mavericks or if the update to 14.3.9 would have crashed with ML, too. Nor do I know if Word would have crashed since I had to get the task in Excel done before an appointment.

Apparently cannot edit the above. Title should have Office 2011, not Office 2001

Running Office 98 or Office 2001 for the Mac with Leopard

Is it possible to run Office 98 or Office 2001 with Leopard?

Can run OS 9.2.2 along with Leopard and access the Office programs that way, and if so do you have to restart the computer to access OS 9.2.2 or can you just launch OS 9.2.2?

Dynamic Memory and Data Deduplication

Hi,
I'm currently testing W2K12 Deduplication feature on some servers, and I was wondering if I could enable "Dynamic Memory" on the VM in Hyper-V? Because the job only uses percentage of memory for the dedup job, I guess it's not possible.
Thanks in advance!

I know it old thread, but I ran into this and could not find anything on it but here, so I am adding my experience.
I can concur with 3magroup...
In my environment Windows Server 2012 with Dynamic Memory and Deduplication enabled, the HyperV does not release the driver locked ram for the dedup optimization. What resulted was an insane amount of paging and a painfully slow VM. Increasing the memory
buffer for the dynamic memory did not cause the HyperV to release the memory for the dedup. Instead, it still "driver locked" nearly all of the ram, which did not make sense to me based on my understanding of the Memory Buffer setting.
I can verify the VM poor performance and dedup using the paging file with the Resource Monitor, disk section, and the Driver locked RAM with RamMap.

Dynamic Memory on Linux VM

Hello!
Hyper-V 3.0 is great! After it will be released, I think it will become the most popular hypervisor. But it remains a major drawback.
Nowhere announced support for dynamic memory for Linux VM on Hyper-V.
Planned at least in some perspective to implement this functionality?
Now we have to use two different hypervisors, as Hyper-V does not meet all the requirements of our customers.

Subject: Linux does not use more than the startup RAM under Hyper-V with dynamic memory enabled
I'm new to LKML, so please don't be too hard on me :)
I'm running Gentoo Linux under Microsoft Client Hyper-V on Windows 8.1
Pro, and I've noticed some odd behavior with respect to dynamic memory
(aka memory ballooning). The system will never use more than the startup
memory defined in the virtual machine's settings.
( VVM: typewriting error viRtual fixed by me, for best search in future )
For example, if I set the startup memory to 512 MB, and enable dynamic
memory with a minimum of 512 MB and a maximum of 8192 MB, the system
will never allocate than 512 MB of physical memory, despite Hyper-V
assigning more memory to the VM and the added memory being visible in
the output of "free" and "htop". Attempting to use more memory causes
the system to start paging to swap, rather than actually allocating the
memory above the startup memory assigned to the VM.
The kernel is built with the full set of Hyper-V drivers, including the
key "Microsoft Hyper-V Balloon Driver" as well as memory hot-add and
hot-remove functionality. This is happening with both the Gentoo-patched
3.10.32 kernel and the vanilla 3.12.5 kernel. The host machine has a
total of 24 GB of memory.
Brian Wong wrote On 3/6/2014 1:20 AM:

For now, I am working around the issue by starting the VM with the
startup memory set to the maximum and letting Hyper-V take the usused
memory back when it is not in use. The VM will then get the extra memory
when it needs it.
Have I encountered a bug in the Hyper-V balloon driver?

Before apply patches ( see in P.S. about native udev-script) we are need use one of this methods:
[ VVM:   URL of this topic skipped ]
c1)
"/bin/cp method" by Nikolay Pushkarev :
Following udev rule works slightly faster for me (assuming that memory0 bank always in online state):
SUBSYSTEM=="memory", ACTION=="add", DEVPATH=="/devices/system/memory/memory[1-9]*",
RUN+="/bin/cp /sys$devpath/../memory0/state /sys$devpath/state"}}
( VVM : of course all need be place in one line, 2 line in this msg. -- only for good visual formating reasons )
c2)
udev rule using "putarg" by Nikolay Pushkarev :
Even "/bin/cp method" udev rule work time to time not as need :-(
As a result, Nikolay Pushkarev write a program putarg.c, that is even faster than "/bin/cp method" :
==
#include <stdio.h>
#include <fcntl.h>
#include <sys/ioctl.h>
#include <string.h>
int main(int argc, char** argv) {
int i, fd;
if (argc < 2) return 0;
if ((fd = open(argv[1], O_RDWR)) < 0) return 1;
for (i = 2; i < argc; i++) {
    if (write(fd, argv[i], strlen(argv[i])) < 0) {
      close(fd);
      return i;
close(fd);
return 0;
==
The first argument - the name of the output file ,
and argument number 2 ( and all subsequent ( if exist ) ) - are text that are wiil be written in output file.
Compile source code to executable file by run command:
gcc -o putarg -s putarg.c
The resulting binary need be placed an accessible location , such as /usr/bin, or wherever you want.
Now udev rule using "putarg" can be written as :
SUBSYSTEM=="memory", ACTION=="add", RUN+="/usr/bin/putarg /sys$devpath/state online"
This complex solutions ( compiled file and udev-rule ) works exceptionally fast.
Best regards, Victor Miasnikov

P.S.
Nikolay Pushkarev about standart udev-script :
Strange, that the native udev-script
SUBSYSTEM=="memory", ACTION=="add", ATTR{state}="online"
triggered somehow through time ( VVM: very often not work as need )

Dynamic memory freezes

Hi guys,
we are using three node cluster with Windows Server 2012R2. Our virtual machines are virtual
desktops with Windows 8.1 guest OS, 4 vCPU and 8 GB of dynamic memory.
Sometimes dynamic memory stops working, guest OS is not able to allocate more RAM and starts to swap. This swapping slows performance of all our virtual machines, since
all virtual machines are on same cluster shared volume. This happens at random RAM amount allocated, for example at 2.6 GB,
which is way below our 8 GB limit.
Live migration helps to solve this issue for migrated VM, after live migration the guest OS is able to allocate
more ram and starts to work properly, swapping disappears. However after some time, problem appears on other VM.
Our physical machines have 2x 10core Xeon and 394 GB of RAM. Only about 30% of RAM is used, so there is free space for all virtual machines. But we need to solve this issue so dynamic RAM starts to work properly.
Do you have similar experience?

Hi manasj,
Please check event log "Microsoft-Windows-Hyper-V Worker/Admin " to see if there is any clue .
Also please refer to the following potetial cause :
" In a Hyper-V Failover Cluster, a virtual machine can have its configuration information stored on cluster shared storage (a Physical disk resource or a Cluster Shared Volume (CSV). If the physical disk resource or the Cluster Shared Volume (CSV) goes Offline or Fails,
the VM placed in a critical state. Once the storage is re-connected, the VM should no longer be in a critical state. However, virtual machine worker process (vmwp.exe) does not refresh all of its file handles."

Dynamic Memory in the production environment

Hi,
We configure all production VMs with static memory on Hyper-v 2012
we need to make sure there is no negative impact on VM performance if we use Dynamic memory , as we read for 2 years
not recommend to use dynamic memory in the production.
I preferred the answer with Trusted URL
Ramy

Hiya,
The best answer you can get is, that it is dependent on the application running on the server O/S.
The reason that dynamic memory is not recommended for production environments, is that many applications are not supporting it. That is usually seen on memory intensive applications(SQL is an example) or simply because of caching types of functions. (SharePoint
is an example).
The major concern here is when VM's are decreasing the memory for a VM, the application does not understand this. Usually it is not a problem when increasing the memory. - Again it will depend on the application.
Think of it as hot swap memory and how you used to use that in the physical machine days.
Also when there is not adequate memory, operating system will use paging. Paging uses disks and disks has a lower access time than memory.
In general dynamic memory is easier to control than dynamically expanding disks, as you can set the buffer size of the memory, which is still not available for the dynamic disks.
Besides the above, the following links states:
"Workloads that are not NUMA-aware will not take advantage of virtual NUMA. However, the guest operating system may perform some NUMA optimization. Enabling Dynamic Memory (therefore presenting only a single virtual NUMA) should not cause performance
degradation"

Dynamic memory allocation failure

Dear reader,
We sometimes have a problem where our windows 2012 r2 RDS virtual servers, that reside on windows 2012r2 hyper-v hosts, loose their dynamic memory and only have their startup memory left to work with. Users start complaining that things are very slow etc.
If I check several screens (RDS Broker load balancing, hyper-v manager, cluster manager and the vm's task manager) it's clear that the vm only has its startup memory allocated. I'm not sure if this happens instantly or immidiatly after the nightly reboot.
To resolve the problem we have to call all users on the vm where it happens and ask them to logoff (if they are even able to), and then we reboot the machine.
I have checked the logs from the machine where the VM resides on and the logs from the vm itself. But I cannot find anything. We also have alot of windows 2008r2 vm's with dynamivc memory, but none of those have ever had this problem.
Searched the internet, but so far it seems we are only.
Can anyone give me a lead to troubleshoot this?
Best regards,
Ruud Boersma
MCITP Enterprise administrator

Hi all,
I'm going to be "one of those people" who revives dead posts for something that is relevant but obviously not fixed... sorry in advance!
We have the exact same situation, a bunch of RDSH guests with Dynamic memory turned on (60+ of them). every day between 1-8 of them will fail to allocate Dynamic memory and will be stuck on their startup RAM amount. This really hurts our users at peak
times.
I have engaged our TAM and have raised a case with PSS, Usual story "your the only one with this problem". Which obviously isn't true.
So, we have tons of free RAM on the hosts, 600GB+ on most of them, the issue affects RDSH hosts at random, across multiple hosts and clusters.
The screen shots attached are of one of our hosts from this morning. it has 8GB startup, 8GB minimum, 32GB Maximum RAM configured, with a 23% buffer. the host has 752GB RAM FREE. Notice how the perf counter "Hyper-V Dynamic Memory Integration Service"
is reporting "0", it should be reporting "32768". also under task manager on the VM we are missing "Maximum memory" which should be just below "Hardware reserved" in the bottom right hand corner.
Looks like the balloon driver is being delayed at boot time, we are going to XPerf all the servers in the hope that we can catch the critter. It's an unusual problem.
We only have Acrobat PDF viewer, word viewer, excel viewer and two custom dot.NET applications installed on the guests. Some of the servers are also just dumb RDSH hosts, with not connection broker configured, using an F5 loadbalancer for load distribution
and session management. All guests are 2012R2 patched up to March 2015, integration Services are installed and up to date (its an enlightened OS remember).

Dynamic Memory is not working all the time

We are in the process off moving our 2008R2 VM's from the 2008R2 HyperV servers to new Server 2012R2 Hosts.
We shut down the VM's copy the files and VHD's to the new CSV's en import the VM in the Hyperv Manager. Then we make them high available in the Failover Cluster Manager (Configure role - Virtual machine). We mount the integration tools and update the
VM to version 6.3.9600.16384
For a specific type of VM (mostly RDS Host servers) we always had Dynamic Memory configured (when they were hosted on de 2008R2 platform), so we are using the same settings on the 2012r2 platform. The memory settings were;
Startup memory: 1024 MB
Minimum memory: 1024 MB
Maximum memory: 12288 MB
These VM's reboot every morning, this is done for specific reasons. But now once in a while (once per week/2 weeks) we notice that the VM's are not using more memory then 1024 MB while the demand is much higher. Rebooting the server helps most of the times,
live migrating to another host also helps. In the VM we see that memory usage in the taskmanager is 99-100%, and after the move it immediately starts using more than the minimum configured amount.
Until the failover the memory usage was 1024 MB and it did not get any higher.
This happened several times. Last week we changed the Memory configuration to:
Startup memory : 2048 MB
Minimum memory: 2048 MB
Maximum memory: 12288 MB
But this morning we had a call about the performance of one of the VM's, We saw that it was only using 2 GB memory while the demand was much higher. After live migrating it to another host it started using more memory immediately.
The 2012R2 hosts are not overcommited, there is a lot of memory still available for the VM's. Those VM's never had this problem on the 2008R2 Hyperv platform.
Any idea why this happens?

Peter,
I think this is a bug of some sort. I say that because the components that make up dynamic memory are as follows.
Memory Balancer(Host service, coordinates how memory changes are made.) This is also what shows the memory demand counter i believe.
Dynamic Memory Virtualization Service Provider (this is included your VMWP.exe proccess, one per VM. Essentially how it runs on the host. He listens to the Service Client for metrics)
Dynamic Memory Virtualization Service Client (this is inside the VM and reports to the Dynamic Memory Virtualizaton Service Provider.)
Since you live migrated the machine it made dynamic memory work on the other host. This means the Service Client is running in the client and shouldn't be an issue. The Memory Balancer is the server and shouldn't be the issue, so this means the "Dynamic
Memory Virtualization Service Provider" is in question. When you live migrate the machine its going to create a new VMWP.exe process on the clustered server. So now the question is it the host that couldn't listen to the service or the worker process
skipped a beat and has a bug.
Out of curiosity does it happen to both hosts? Also have you profiled the servers to see how much memory they really require on start-up? When you reboot the RDS servers, how many VM's do you reboot and is it a staggered process?

Dynamic memory not released to host

Dear Techies,
Ours is a small Hyper V virtual server infrastructure with three DELL power-edge physical hosts(Windows server 2012 Datacenter) and around 15 virtual machines running on top of it. The hosts are added to fail-over cluster. Each host has 95 GB RAM. All the
VMs are running Windows server 2012 standard edition.
We have installed terminal services(TS licensing, TS connection broker, TS session host) in four VMs with the following dynamic memory settings:
Start-up RAM : 2048 MB
Minimum RAM : 2048 MB
Maximum RAM : 8192 MB
Below mentioned applications are configured in the server:
Nova Application Installed
SQL Developer Tool is Configured (ODBC Connection established for Database communication)
FTPs communication allowed for File Transfer
McAfee Agent is configured (Virus Scanner)
Nimsoft Robot Agent Configured – Monitoring
Terminal Service
Enabled Multiple terminal sessions based on customer requirement
BGinfo tool configured through group policy for customized desktop background
The average memory utilization in the terminal servers are 3.6 GB. As per dynamic allocation the maximum RAM requirement/allocation till date is 4GB. As seen in Hyper V console, the current RAM demand is 2300 MB and assigned memory is 2800 MB.
However, the earlier assigned RAM in the server is ballooned/faked to the VM as driver locked memory. This is by design. Despite the memory being released back to the host, the server still shows up the 4Gb which makes the memory utilization report from
monitoring tools look 80% (3.2 GB out of 4 GB).
As a result, the memory utilization report is always based on the current dynamically allocated RAM and not calculated based on the maximum assigned RAM(8GB in this case). To make it clear: If the
currently assigned RAM is 4Gb and utilization is 3.2 GB the utilization % is reported as 80%. However, if calculated in accordance with maximum RAM capacity of the server it would be 40% ((3.2/8)*100).
Is there any way to release the driver locked memory from the VM.?

I am not really clear on the point of your question.
Allocated RAM is what is currently in use / allocated to a VM out of the physical RAM pool. It is Demand + Buffer. The demand is based on the applications in the VM and what they think they need and how efficiently they return unused memory
to the machine. This has nothing to do with in-application paging (which happens a lot with Terminal Servers).
So yes, the memory utilization is accurate in relation to physical RAM utilization.
Dynamic Memory is about efficiency, not about over-allocation. Hyper-V can never give VMs more RAM than is in the physical RAM pool. The VMs can be configured to have more RAM than is in the physical RAM pool - but the VMs will hit the top of
the pool and not be allowed to have any more. There is no ballooning or paging to disk.
So, you maximum allocated could go beyond what is possible. But that would mean that your utilization would be artificially low if this was used in the calculation.
