Parallels Partition Question

I know this probably belongs in the Parallels forum, but it appears to be down (forum.parallels.com).
I am planning on doing an upgrade install of Leopard, and currently have a Windows Parallels image (non-bootcamp). I am interested in having a Windows bootcamp image and I know that Parallels will read my bootcamp partition. So my question is.. If I repartition my machine with a partition for Bootcamp, is there any way to copy the contents of my Parallels image over to the bootcamp partition and have it be bootable?
Thx

Thanks a lot. While i am at it, if i use the bootcamp partition with Parallels, i cannot suspend the VM right?
Parallels will behave the same, whether it has its own copy of Windows, or is using that on the Boot Camp partition.
The only difference is backup. If you use Parallels with Windows in a disk image file (Preferably a sparse bundle), Windows can be backed up with Time Machine. If Windows is on its own partition, Time Machine can't handle it.

IMac with 4GB - Parallels partition slowing down

I have an iMac mid 2007 with max memory of 4Gb. I run Windows 7 in a Parallels partition. on both sides I do little else than browse and use Office. Since installing Mountain Lion, the Windows system has been runing slower and slower. Advice from Parallels is to clear the temp folder. They don't seem concerned about the size of the partition.
My question is: is there something I can do to get the performance back up to reasonable speed? Put another way, how can I tell whether the hardware I have simple will not support Mountain Lion and Windows 7 together. I have avoided moving to Windows 8, but do have Office 2013, and it drags.

Upgrade the RAM, 4GB is a minimal amount of RAM these days. To see how you RAM is being used, carefully read Apples instructions on Activity Monitor. You can find them by clicking:

How do I clone Parallels partition for migration to another computer?

I have Parallels on my MBP (Lion OSX). In Parallels (Windows 7 operating system), I have internet banking set up and since this was very difficult to do, I want to migrate the Parallels partition in the same state that it's in to the new computer.
The machine I am migrating to does not have Parallels set up on it.
The second (destination) computer is an MBA with Snow Leopard on it (it originally came with SL and I was using that OS before the computer broke down. I am getting it back from repairs soon). I want to stay with SL on the MBA. Therefore I can't make a clone of the Mac HD of the MBP and simply restore that to the MBA. I believe that if I did that, I would have the Lion OS on the MBA even if I installed SL on the MBA before doing the migration.
The Mac HD part is not a problem. I made a clone of the Mac HD of the MBA before I sent it off for repairs. So I can easily restore the Mac HD onto the MBA.
But I do not have Parallels on the MBA. I installed Parallels and set up internet banking on the MBP (after I sent the MBA off for repairs.)
How do I move the Parallels that I installed on the MBA (Lion OS) onto the MBA (SL), keeping everything the same, that is, with all the files preserved?

When I go into Parallels, I see a "Clone" option. Will this clone Parallels for me?
It's really important that I have an exact clone of Parallels and its contents.
You already have a copy of the files needed, they are in the Parallels folder, usually located in 'Documents'

How to use flashdrive on a Mac book Pro in the parallels partition

I cannot use a flashdrive in the Parallels partition (windows XP) of my mac book pro. The flash drive works on the mac side fine. I get this message:
USB device you are trying to connect to the virtual machine is being used by another process. Wait 5-10 seconds, then try to connect the device again. If this does not help, find the application that blocked up the device and disconnect it manually.
Following this advice does not remedy the problem at all. How can I get the flash drive to work on both sides: Mac and PC?

When you remove the flash drive are you ejecting it or just unplugging it? If the latter then you need to use the system eject to remove it. You must also eject it properly from within Windows.
It would help if you provided the version of OS X you are using in your configuration as well as more info on the hardware model and configuration. This information helps us know about your setup in order to provide assistance.
Also, what version of Parallels are you using? Do you have USB support turned on in Parallels configuration? Have you searched the Parallels forum for possible solutions or posted your problem on their forum? This should be your first place to look for help, not the Apple Discussions.

Data Warehouse Partitioning question

Hi All,
I have a data warehousing partitioning question - I am defining partitions on a fact table in OWB and have range partitioning on a contract number field. Because I am on 10gR2 still, I have to put the contract number field into the fact table from its dimension in order to partition on it.
The tables look like
Contract_Dim (dimension_key, contract_no, ...)
Contract_Fact(Contract_Dim, measure1,measure2, contract_no)
So my question:
When querying via reporting tools, my users are specifying contract_no conditions on the dimension object and joining into the contract_fact via the dimension_key->Contract_dim fields.
I am assuming that the queries will not use partition pruning unless I put the contract_fact.contract_no into the query somehow. Is this true?
If so, how can I 'hide' that additional step from my end-users? I want them to specify contract numbers on the dimension and have the query optimizer be smart enough to use partition pruning when running the query.
I hope this makes sense.
Thanks,
Mike

I am about to start a partitioning program on my dimension / fact tables and was hoping to see some responses to this thread.
I suggest that you partition the tables on the dimension key, not any attribute. You could partition both fact and dimension tables by the same rule. Hash partitions seem to make sense here, as opposed to range or list partitions.

LPAR - LOGICAL PARTITION QUESTION -

Hello SDN Experts.
LPAR (LOGICAL PARTITION QUESTION)
Our current Production Environment is running in Distributed Installation on
IBM System P5 570 Servers AIX ver 5.2, each node is running two Applications: SAP ERP 2005 SR1 (ABAP + JAVA) and CSS. (Customer Service System)
Node One
u2022     SAP Application (Central Instance, Central Services)
u2022     Oracle 9i Instance for CSS Application.
Node Two.
u2022     Oracle 10G Instance for SAP Application
u2022     CSS Application.
To improve performance we are planning to create a new LPAR for SAP.
According to the IBM HW Partner LPAR is logically isolated with different HW/SW resource(CPU/Memory /Disk resource, IP/hostname/mount point)...
Question:
I have this two possible solutions to copy SAP instances (app + db) to new LPAR, can I apply SCENARIO 2, which in my opinion is easier than SCENARIO 1.
SCENARIO 1.
In order to migrate application and database instances to the new LPAR do I need to follow the procedure explained in the guide:
(*) System Copy for SAP Systems Based on SAP NetWeaver 2004s SR1 ABAP+Java Document version: 1.1 ‒ 08/18/2006
SCENARIO 2.
After create all file systems (required in AIX) to copy data from Applications and Database Instances to their respective LPARs and change the ip address and hostnames in parameter files according to the following SAP Notes:
Note 8307 - Changing host name on R3 host
Note 403708 - Changing an IP address
Which is the best scenario SAP recommends in this case ?
Thanks for your comments.

If your system is a combined ABAP + Java instance you can´t manually change the hostname. It´s not only those places that are listed in that note but much more, partially on filesystems in .properties files, partially in the database.
Doing that manually may work but since the process is not documented anywhere and since it depends on the applications running on top of the J2EE instance it´s not supported.
For ABAP + Java instances you must use the "sapinst-way" to get support in case of problems.
See note 757692 - Changing the hostname for J2EE Engine 6.40/7.0 installation

Oracle 10g and parallel query question

Hi Oracle on SAP Gurus!
We are currently thinking of activating parallel query for certain segments (large application tables and indexes). We searched in SAPNet and SDN and have also studied the SAP Note 651060. But we did not find a complete answer to the following question which is very important for us:
Which kinds of queries (despite from full table scan and index scan in partitioned indexes) support parallel queries and which ones do not support parallel queries?
This is important for us to find out whether we have candidates for parallel queries or not.
Thanx for any hint!
Regards,
Volker

But why do you not propose to use parallel query in OLTP systems?
If the queries are accessed very frequently you will just run out of cpu and io ressources. OLTP systems are (historical) typically multi user systems. You can off course use PQ for 'single user' activities, like index rebuilds, some batchjobs, but you shouldn't do for frequent user queries.
If you have time look at this interesting Article [Suck It Dry - Tuning Parallel Execution|http://doug.burns.tripod.com/px.html]
It is quite old, and you don't have to read all tech details, but i recommend having a look at the conclusions at the end.
May it make sense to use partitioning of these tables in conjunction with parallel query?
I know some guys, who do partitioning on OLTP systems, even SAP systems. But they don't use PQ then. The use partitioning to work on a smaller set of data. In your case the range scans, would need to scan only one partition, saving buffer cache and effectively speeding up execution. So you don't need PQ to scan all partitions at all, this would be a typical OLAP approach.
Best regards
Michael

Parallel Execution questions

Hi everyone, i have few questions about Parallel Execution.
1- Query Coordinator to scan the table, split up the table to the processes. But, each process take different number of rows. For example, in oracle 10g database architecture, thomas kyte gave an example:
"SELECT COUNT(*) FROM BIG_TABLE"
It is distributed to 4 processes. One process take 1000 rows, another process 1200 etc. Why this is not equal? How the number of rows is determined by the QC?
2- If we do not determine the degree of parallelism ( /*+ PARALLEL(B) */ instead of /*+ PARALLEL(B,16) */ ) how the cbo determine the degree of parallelism?
3- in the explain plan i see lots of thing i do not know. For example :
:TQ10000
what is that?
-> TQ, IN-OUT, PQ_Disturb columns?
thanks for responses.

Hi
Why this is not equal? How the number of rows is determined by the QC?The number of rows is not used to split the table. Data is split in granules and distributed to the slave processed based on two methods:
- partition granules: a whole partition is given to a specific slave process
- block range granules: range of blocks are given to each slave process
So, depending on the size of the granules, one slave process might process much more data than another.
If we do not determine the degree of parallelism how the cbo determine
the degree of parallelism?It depends on the configuration. In fact, there is a default at session level, at system level and at table level. Depending which ones are set, a DOP is chosen. In addition, the DOP might be decreased at runtime (before the execution starts, not dynamically during it).
For example : :TQ10000 what is that?Producers send data to consumers through so called "table queues" (TQ). The number, in your case 10000, is just a identifier generated by the database engine.
TQTable queue, e.g.: TQ10000 -> Q1,00
IN-OUTThis is the relationship between parallel operations. E.g. P->P means that a parallel operation sends data to another parallel operation.
PQ_Disturb columns?This is the method used to distribute rows. E.g. RANGE means that the producers send specific ranges of rows to different consumers.

Partitioning questions with windows

i want install windows on my mbp so i can run solidworks and other programs that aren't compatible with mac os. i would also install microsoft office for windows. my question is if i'm booted in mac os could i access the files saved in windows partition (like solidworks files, office files, etc)? not that i need to open them or anything but if i wanted to put them on a USB or move them somewhere, could i do that?

You can also run Windows concurrently with OS X as an alternative to Boot Camp's dual boot setup.
Virtualization for OS X:
     1. Parallels Desktop for Mac and Windows XP, Vista Business,
         Vista Ultimate, or Windows 7. Parallels is software
         virtualization that enables running Windows concurrently
         with OS X.
     2. VM Fusion and Windows XP, Vista Business, Vista Ultimate,
         or Windows 7. VM Fusion is software virtualization that
         enables running Windows concurrently with OS X.
     3. VirtualBox is an Open Source freeware virtual machine such
         as VM Fusion and Parallels that was developed by Solaris.
         It is not as fully developed for the Mac as Parallels and VM
         Fusion.
Note that VirtualBox, Parallels, and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech Labs- Virtualization Benchmarks, January 2013 | MacTech for comparisons of Boot Camp, Parallels, and VM Fusion. Benchmarks of all of the above can be found in Benchmarking Parallels, Fusion, and VirtualBox Against Boot Camp - The Mac Observer.

Recovery Partition Questions

I'm trying to install windows 7 via bootcamp but the disk utility cannot partition the drive because it is fragmented.
the error message says to reformat the drive.
I'm ok with doing this but i have a few quesitons and want some clarity:
1) I'm fully backing up my computer with time machine
2) I have Lion, so by restarting and holding command+r I'll access the Recovery Partition?
3) HERE IS MY MAIN QUESTION, if I select "reinstall OS X" will it reformat my drive??? This is my main issue so I want to make sure it actually reformats the drive into a non fragmented drive.
4) I do not have a bootable OS X disk, but because this is lion it will download and reinstall the os x over the internet correct (through my apple ID login)??
5) To restore my back up, I wait until the new os x is finished installing, restart then access the Recovery Partition again and select "Restore From Time Machine Backup" correct??
or do I:
1) Back up with time machine,
2) restart and hold " command+r"
3) erase drive with disk utility,
4) exit disk utility
5) Select "reinstall OS X" which will reinstall Lion (i have a pre mountain lion comp)
6) select "Restore From Time Machine Backup"
Thanks -Ian

1) Back up with time machine,
2) restart and hold " command+r"
3) erase Macintosh HD partition with disk utility,
4) exit disk utility
5) select "Restore From Time Machine Backup", without reinstalling
6) Choose your last backup date.
If you select "reinstall OS X", you will use the Setup Assistant (the "Migration Assistant") at the first boot on the new system.

Simple UEFI GPT Dual boot with windows 8 boot partition question.

Hi everyone,
I think it's obvious from the quuestion that I'm a newbie here (and from the location of the post) but I have read (several times):
https://wiki.archlinux.org/index.php/UEFI
https://wiki.archlinux.org/index.php/UEFI_Bootloaders
and the incredibly helpful:
https://wiki.archlinux.org/index.php/Beginner%27s_Guide
along with many forum posts. unfortunately this:
https://wiki.archlinux.org/index.php/Wi … _Dual_Boot
appears out of date and so I need to ask you fine people my question.
If I want to dual boot Arch with my Windows 8 my question is on the boot partition. I have an existing windows EFI boot partition. should I mount this partition to my "/mnt/boot/efi" folder and then copy the files to this partition when I am setting up rEFInd (my chosen bootloader from wiki page, comments/suggestions are welcome) or should I setup a separate boot partition for my arch installation. I assume from reading about rEFInd that the former is how I should do it as this seems to be how refind would be able to "see" my windows bootloader.
The reason I am double checking and asking here is I know that windows can be a temperamental beast and is very prone to not booting so I don't want to mess with the windows boot partition unduly.
Thanks in advance guys, looking forward to getting my arch working!

$esp = EFI System Partition?
also, ok, gummiboot, I'm glad I can mount the esp as /boot (that was my original thought but reread the tutorial and wasn't sure) just double checking, it is the esp created by windows 8 that I mount?
in addition, as I am slightly new to this is there any tutorial that can tell me how to set up gummiboot? I've looked here:
http://freedesktop.org/wiki/Software/gummiboot
but don't see anything in the way of detailed instructions.
from your post: https://bbs.archlinux.org/viewtopic.php?id=159061
I'm gonna guess it's something like this (please let me know if this is right)
/mount $ESP /mnt/boot
pacman -S gummiboot
(after chrooting)
//exit chroot
gummiboot
*stuff saying gummiboot is not configured*
gummiboot install
is it something like that? can anyone point me towards a manual

Mac OS X, User Folder and Case-sensitivity (plus a Partitioning Question)

Hello everybody.
Today, I'd like to start a new thread regarding the configuration of OS X and the formatting of the drive with a HFS+ (case-sensitive, journaled) file system.
There is a problem that has been tormenting me for quite some time now, and so far I haven't been able to find a losution yet.
Here is the issue. When I bought my MacBook Pro (early 2011), I changed the main dirve to an hybrid SSD destinating the original 750GB to a Time Machine backup disk. As a consequence I had to make a fresh install of OS X. When it came the time of formatting I've opted for:
Creating two partitions: 1 for the OS and 1 for the user folder (I have only one admin-user). Back then, I was coming from a Win enviroment and having two partitions seemed to be the best option for me. (Less chanche of user-data corruption in case something goes wrong in the OS partition).
Chose a HFS+ (case-sensitive, journaled) file system. It seemed to be the more complete alternative.
Everything was absolutely for a couple of months then I encountered the first issue: Adobe products don't work on a case-sensitive fs.
I managed to get Photoshop to work eventually (manually correcing folders name) and didn't care too much about the rest.
In the meantime over a year has passed and I kept the mentioned configuration, uptdating to Lion and ML. Recently another couple of isses have appeared: AutoCAD presents the same problem as Adobe and there is an issue in the keyboard balcklight control (from forums seems that ML is not able to store any information in System Preferences regarding the backlight).
Despite the fact that case-sensitive fs seems to be the future solution chosen by Apple, it is still premature to have it as OS fs unless you are an hard-core developer that don't care about tons of programs that would eventually miss from your application folder.
Being decided to move back to a case-insesntive fs, I need wish I could calrify a couple of doubts before proceding:
(Not relatete to fs) Is it a good practice to keep user folder on a separate volume? Does it generates any issue on the base of your experience?
Is it possible to have the OS on case-insensitive fs and the user folder on a case-sensitive one? Does the OS have an issue with that?
The second point is the most critical as my data are now on a case-sensitive volume. They mostly consists in documents, images and music which should be migrated on a case-insensitive volume seamlessy, however, I'm not 100% sure about what happened during the last year (i.e. if there has been the generation of not-unique names).
Furhtermore, I wish I could keep a case-sens volume as I plan to be dealing with a Linux enviroment soon. If that could be the user volume, this would be amazing.
I'd also like to ask personal opinion on advantages of having case-sens fs.
I understand I asked lots of questions in a single post. I hope, however, that this thread could be a base to collect some of the quite dispersive topics related to case-sensitivity present on the web.
Best Regards,
Alexander

Linc, in the provious post you said there might be issues having user data on a separte partition.
Which kind of issues are you tihnking of? Have you ever encountered such problems?
The biggest risk is that poorly written software will assume your home directory is at /Users/you and will fail (or worse) if it doesn't like what it finds there.
I really appreciated if you could be more specific and don't worry about being too technical.
There are two ways you can go about it.
1) Set everything up normally as if you only had one partition. Create your user on that one parition. Then, copy all the real user data to the 2nd partition. Using your admin account, make sure that all the permission on the user folder on the 2nd partition are the same as on the original partition. The, use System Preferences > Users & Groups > your account > right/control click > Advanced > Home directory and change it to the home directory on the 2nd partition. Log in to that new account. Make sure everything works. Then delete the user directory at /Users.
2) A even more robust, old-school option is to create an /etc/fstab file and have your 2nd partition mounted at /Users. Then, everything will function normally and your user home directories will all be at /Users. /Users will, however, be on a different volume.

Partition Question

Hi,
I have a MacBook with a 80GB HDD, 5GB of it is partitioned by bootcamp and has Linux installed on it. My first question is will I be able to unpartition the HDD without destroying my data? Secondly, Now that bootcamp is over, is there any other applications that I can get for free to do the above. Finally, If I cant get an application to do that, If I get Leopard will it definatly be able to unpartition the HDD?
(If i set my clock date backwards I am told by bootcamp:
The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows. )
Would I be able to unpartition without loosing data if I get leopard even though I have that message?
Thanks and sorry about all the questions.
Looking for a quick reply please

You might find this link to about the same question. I detailed the persons answer and how to go about it. Hope this helps you.

Oracle 8i hash parallel update question

Hello All,
Fairly new to Oracle (old Sybase guy). Using Oracle 8i. Trying to
get an update to run in parallel against a table. Partitioned the
table 4 ways using hash partitioining. Please see the following
query/plan. I am trying to determine if this query is actually running
in parallel or not from the plan? If it is not, what might be
preventing it from running in parallel? I would expect Oracle would
kick off one thread to update each of the four partitions of the
sales_tran_detail table.
Appreciated,
Jeff

Thanks everyone for the responses on this. I have tried everything suggested thus far and still do not get what I can recognize as an explain plan that shows parallel execution or multiple threads when running. I would have thought the hint would have forced it to happen!
My parallel_max_servers is set to 6.
I copied in the header as stated in goodwithalls email.
I enabled parallel dml for the session and played with "..adaptive_multiuser_tuning".
I still get exactly the same plan as posted and still 1 thread. I wonder if Oracle just doesn't like doing updates vs. hash paritioned tables in 8i? It claims it does it vs. paritioned tables but maybe hash doesn't count.. or it wants me to create paritioned indexes too or something wierd..
Still lost on this one,
Any other thoughts anyone?
Thanks,
Jeff

Partitioning Question - range partition?

Hello all
we have an issue with the amount of data we have in a particular schema that we are using to store production metrics. I have looked at a few options and are now trying to design a solution using partitioning. At a very high level we have data in 7 tables that need to utilise partitioning:
JOBS
FILES
MAILPIECES
MAILPIECE_DETAILS
TNT_DATA
BAGFILES
POSTAL_BAGS
Ideally I would like to use a RANGE partition as I can fairly easily use a date as the range - my issue here though is that only the FILES table has a DATE column on it.
So my question is, for the other tables, is it best practice to use the same 'sort of' partitions - in which case I would need to add a DATE column to each subsequent table and populate it correctly (based on the date in the FILES table - as the FILES table is acting as the PARENT table for all the other tables). Or, should each table be treated individually and partitioned using whatever method is appropriate for that table?
Any help would be greatly appreciated.
Many thanks
Paul

Hi,
if you are running 11g and all other tables are indeed children to FILES then consider reference partitioning.
