Setting Partition in U400

Hi everyone, I have just gotten U400.
Currently, first bootup: C: 470GB and D: 30GB, which is the Lenovo backup files.
Need help in setting partition in the C:. Is there any ways to add another partition?
I have used the Computer Management to set C: to 200GB. but it dont allow me to to set a "simple volume" on the unallocated space.
Is there any ways to setup the recovery to set the volume of the disk? I have done such for my pc using bootup.
but the U400 don't seem to allow me to do so
Will appreciated any advice

Thanks for the reply.
The create table statement above was just an example. Yes, i will go for YEAR interval.
But the thing is when i take Invoice_date in Prompt, I've to put Year(Invoice_date). Will that use partition or...?
Dear rp0428,
my queries would be normal select from Invoice Sales table but where clause would have year,organization_descr and 1 more column. year & organization_descr filter would remain for most of the analysis.
Regards!
We aren't asking for some general statement about what your query 'might be'; Oracle works with actual queries. If you want an 'actual' answer provide an 'actual' query.
Oracle can't use 'year' to query a column of type DATE unless you turn it into a date using TO_DATE.
And the Oracle server knows NOTHING about 'Prompt' or 'Year(Invoice_date)'.
Partition pruning can only occur if the partition columns are included in the WHERE clause.

A few questions on setting partitioning the hardrive.

Hello,
I am reinstalling Arch because I want to make the jump from i686 to Arch64. I really want this to be the last time I reinstall an OS on this laptop, so I have a few questions on the most efficient way to set up the partitions.
1) Is it safer to have a seperate boot partition? I really don't mind setting aside 100MB or so for boot, but I keep hearing you really don't have to do that with Arch anymore.
2) How does optimization work? Are partitions that are created higher on the list faster to access? What I'm looking for is a really fast computer while in use. I don't care about boot time very much, and my swap drive is barely used. Would this be a good set up for what I'm looking for?
SDA1 Root
SDA2 VAR
SDA3 Home
SDA4 Swap
SDA5 Boot
3) Is ext4 a good idea? I really like the speed and all that, but it's still in development, right? When it's finished, would I be able to update the filesystems or once I make them are they always stuck in their current state? I was thinking ext2 for boot then ext4 for everything else.

I'm not too sure on that one as i have never tried it but it might be possible to boot from your live cd, backup your /var partition reformat it then copy the data back on to it but don't quote me on that.
I don't think you will notice any difference regarding which order you mount your partition's, I have been through a bunch of different partition setup's and have not noticed any speed difference between them only between different filesystem's
I have the same partition setup as your first post minus the boot partition
/dev/sda1 / ext4 defaults,noatime 0 1
/dev/sda2 /var reiserfs defaults,noatime 0 1
/dev/sda3 /home ext4 defaults,noatime 0 1
/dev/sda4 swap swap defaults 0 0

About: making RAID sets - partition independant?

(the querry made simple: look last 2 lines)
When making a RAID set, whatever the type it is, will it rely on the partitions or on the disk itself?
In the Disk Utility help it keeps mentioning "disk", and when I was about to create a set, it also asked me about "disk".
I have set up 2 partitions for the purpose of testing RAID for me, being about the same size on a big backup drive.
The drive itself also has a bit of free space filled with original files.
So I wanted to mirror, say, RAID test 1 and RAID test 2, both of them being on the same disk.
Will it work?
Or will it wipe my disk?

A RAID may be constructed using individual partitions on separate drives although using the whole drive would be preferred for speed. You could actually RAID multiple partitions on the same drive, but of course what would be the point.
I've actually used two drives each with three separate partitions and created three separate RAIDs of two partitions each. Not particularly efficient but it does work.
There is really no point to creating a RAID of two partitions on the same drive. And, certainly no point creating a mirrored RAID this way.
Any RAID you create with Disk Utility will erase the drives used (or partitions.)

For basic definitions and discussion of what a RAID is and the different types of RAIDs see RAIDs. Additional discussions plus advantages and disadvantages of RAIDs and different RAID arrays see:

Hardware or Software RAID?
RAID Hardware Vs RAID Software - What is your best option?
RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
Pros and cons
Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.
For more detailed information on the differences between Software RAID and Hardware RAID you may want to read: Hardware RAID vs. Software RAID: Which Implementation is Best for my Application?

Setting partition count globally

Hi,
I have the following questions about distributed services
1. I understand that the recommended value for partition count for distributed caches is the first prime number higher than the square of the number of JVMs. Is it possible to set this value globally for all the distributed services?
2. Are there any thumb rules for determining thread-count for my distributed services (for compute intensive and write-behind services)?
3. I have a large number of write-behind caches using using same distributed service. Is there any advantage of creating multiple distributed services for the same configuration and split up the caches between these services?
Thanks
Sairam
Edited by: SairamR on Aug 31, 2009 11:31 PM

Hi Magnus,
A few reasons for running multiple services are
- separation of code for testability (individual services can be more isolated from each other and could be developed by different teams, too)
- separation of services which would compete for resources, by having different layers of nodes, one layer storage-enabled for one service, another for another service
- separation of service threads due to reentrancy problems (cache store or other code running on the service thread of one service could this way use the other service)
- separating of data to a subset of nodes
You can't override partition count it on a global basis out-of-the-box, but there are several ways to do that
- either with appropriately changing the operational configuration file (tangosol-coherence.xml) adding a system-property attribute to the distributed cache service service-scheme part declaring the default value partition-count, or changing it to your liking
- or possibly (this may not work) also by defining an operational-config override file (overriding the respective element in the distributed cache service service-scheme part declaring the default value partition-count)
- or by having a common ancestor distributed-scheme for all the distributed cache services which defines a override with the system-property attribute
Best regards,
Robert

Setting Partition Arguments (log flags) using FSCRIPT??????

Hi,
I can't succeed in setting parameters in FSCRIPT that require quotes (as
__-fl "(err:sh:*)"__:
1)
SetPartArgs VisionFrontEnd "-fl aFile(err:sh:*) +(trc:user9:*:*) -fm
(n:1024,x:800000,i:128)"
This sets the line, but the partition can't start.
2)
SetPartArgs VisionFrontEnd "-fl "aFile(err:sh:*)"
"+(trc:user9:*:*)" -fm "(n:1024,x:800000,i:128)"
(with or without '\' protecting)
This sets the line to 'empty', with an error saying that aFile(err:sh:*)
can't be found
How to set something on the parameter arguments list that contains log flags
?

While the user long and short name is a matter of convenience when logging in (the computer will "prefill" the user name at the server login window based on what account was used to log on to the local machine), what counts is the UID number of the account.
Most "home" user accounts end up with a "501" UID meaning that it is the first account created and it is an administrator account on the home machine.
What we have found is users are quite creative as to what they use for account names on their home machines and most times they are not compatible with the company standard of first initial last name we use for accounts.
So we let them do what they want but let them know the login and password of the network account so they receive access to network resources based on that account.

How to install Vista off Recovery disk without setting partitions?

Hi,
I have my recovery disk and I installed a new 320gb HHD.
When I installed the recovery disk, it re done the partitions 160gb in each (2 partitions plus 1 recovery partition)...
But I want to dual boot with XP pro due to software issues and I prefer it sometimes...
I have redone my partitions, 1st- 51gb for XP pro(32bit), 2nd- 51gb for vista(32gb) and the 3rd- 210gb is for storage
How do I install with Toshiba vista O/S and stuff that comes with it on the recovery disk, just on to the 2nd partition without touching how I have set the hard drive up....
I already have about 100gb of pics, music and cam vids on the storage, with nowhere to put them so I cant risk them as some are only copies (so it might be a good idea to let me know how do I back up whats on my storage partition to DVD's please)
If I cant, then can some1 please tell me how I get my OEM Toshiba vista off this recovery disk or link one to me?
Hope all this makes sense lol... thanks
Shane

If you have so many important material best back up is to buy external HDD and copy all this stuff there. I recommend you to buy small 2,5 external HDD and when necessary you can take it with you and connect to any computer if you want to show or copy this file. External HDDs can be connected to other computers with delivered USB cable.
Back to your partitions.
When you use original Toshiba recovery installations DVD you will have 3 partitions.
-WinRE partition and it belongs to Vista OS. This partition is not visible and this is not a kind of Toshiba recovery partition
-partition C for Vista
-partition D/or/E for DATA. On this partition is saved recovery image in folder called HDDRecovery
I don't know which notebook model do you have but this configuration is on all new Toshiba notebooks delivered WITHOUT recovery media.
Using Toshiba recovery media you will be able to get exact mentioned partitions structure. Using recovery installations media you WILL NOT be able to install Vista on second partition.
So if you want to have dual boot with WXP you can do follow:
-At first you will install Vista with recovery media and on second partition you will install your WXP version
-At first you will install WXP and then you can install Vista on second partition but you must use Microsoft installations disc. Recovery media cannot be used.
That's all I can say from my experience with this stuff.

Use GUID for setting partition element with bcdedit

The following is an example of a valid BCDEDIT command:
BCDEDIT /set {ntldr} /device partition=d:
If a disk were added to the system and the drive letter of the
partition just referenced was no longer "d:" then it would not
be found by the loader.
Could a volume name such as
\\?\Volume{e1e236ee8-7dbd-1223-a442-806d61f356de}
be used in place of the drive letter in the same command ?
(If not, my next question would be how to reset the
element in a script...perhaps some hints?)
Thank you.

Hi,
Which OS are installed in the disk you attached to system? Windows XP?
Do you want to makes a dual boot?
Please run bcdedit /enum in privileged command prompt, and upload the result here.

How can I mount a Raid set (partition in an external drive)?

Hi,
I have 3 partitions in my external drive. I tried to create a concatenated Raid from 2 of the partitions. However, I end up with an offline Raid Slice (one of the partitions is under this slice) which is grayed out in Disk Utility.
When I try to delete the Raid Set, I get "Deleting RAID set failed. This RAID configuration is not valid" warning. When I try to erase the RAID volume, I get "Volume Erase failed with the error:The chosen size is not valid for the chosen filesystem." warning. I cannot mount the volume either.
So, I have 2 of the 3 partitions mounted. The 3rd partition (which is under RAID) is unmounted. Do you have any suggestions to have access to the 3rd partition?
Thanks.

Why are you trying to RAID two partitions on the same drive? Aside from the fact that it doesn't work it also makes no sense when you can simply create a larger partition by joining the two into one.

Your disk could not be partitioned Problem

Hi, im having issues with installing windows on my mac, which it seems like most people do haha. I have a Macbook Pro 13-inch, mid 2012, with 10.8.4, with a 2.5Ghz Intel Core i5, a 4 GB 1600 Mhz DDR3, and a Intel HD Graphics 4000 512 MB. I got a download through my work for Windows 8 pro, 64-bit. I first downloaded it through a download manager but when I ran bootcamp assistant, and checked all three boxes, in the picture ().
I recieved an error trying to put it onto a 16gb usb. I redownloaded it through firefox, and when I tried again, it download windows 8 along with the software support. I set windows to 80 GB and set partition, but then I recieve an error that the disk could not be partioned ().
Any ideas what the issue could be?

Well along with 1000 other identical posts,
your disk needs to have unfragmented free space.
sometimes just shrinking the partition and then moving it back to full length works.
Not sure why the support software which has to be on FAT volume failed.
How do I use the Boot Camp 5 Support Software I downloaded from the web page?
The download file is a .zip file. Double click it to uncompress it.
Double-click the Boot Camp disk image.
Copy the Boot Camp and "$WinPEDriver$" folders to the root level of a USB flash drive or hard drive that is formatted with the FAT file system (see question below for steps on how to format).
Install Windows, leaving the flash or hard drive attached to the USB port of your Mac.
Installation of the drivers can take a few minutes. Don't interrupt the installation process. A completion dialog box will appear when everything is installed. Click Finish when the dialog appears.
When your system restarts your Windows 8 installation is done.
Note: If the flash drive or hard drive was not attached when you installed Windows and was inserted after restarting into Windows 8, double-click the Boot Camp folder, then locate and double click the "setup.exe" file to start the installation of the Boot Camp 5 Support Software.How do I format USB media to the FAT file system?
Use Disk Utility to format a disk to use with a Windows computer. Here's how:
Important: Formatting a disk erases all the files on it. Copy any files you want to save to another disk before formatting the disk.
Open Disk Utility.
Select the disk you want to format for use with Windows computers.
Click Erase, and choose one of the following from the Format pop-up menu:
If the size of the disk is 32 GB or less, choose MS-DOS (FAT).
If the size of the disk is over 32 GB, choose ExFAT.
Type a name for the disk. The maximum length is 11 characters.
Click the Erase button and then click Erase again.

Installing Boot Camp - There is only one partition available for Windows

I have a brand new Mac Mini. Ran Boot Camp assistant and created Windows partition - 80 GB. Then when instructed, inserted Windows XP install disc. It went through some install steps then came to screen where you chose the partition to install Windows. There was only one partition showing - Partition 1. I think that's the Mac partition, so I quit install, removed partition with Boot Camp and tried again, this time setting Windows partition at 32GB. Insert Windows install disc, same result - only Partition 1. I called Apple support, we did it all again - same result. They had me completely reformat my Mac disc with the OSX discs, then run Boot Camp assistant and set partition to 32 GB. Same result - only Partition 1 is available. The Windows install disc I am using is the same disc I used to put Windows on my son's MacBook about 9 months ago.
I need this Mac Mini to run both OS. What to do?

Use NTFS for Windows and buy Paragon NTFS for OS X
You can also try Paragon HFS for Windows
As long as you are using for data and backups, you can leave the drive as GPT too.
I would recommend strongly to always have a 2nd bootable Mac OS drive, only need 30GB partition. System maintenance. Though LIon Recovery Mode finally makes it less but not totally unneeded.
And yes you can use Windows to create a partition.
Boot Camp is too broad. Do you want or mean BC Assistant? not needed but probably possible.
MBR has trouble with 3TB drives.

Windows 8 Deleted Recovery Partition and Saved but No Boot

Hi
I ve Hp Pavilion G6 - 2336el , i bought it 5 months before and 2 days before i installed Ubuntu but by mistake ubuntu deleted all partitions (included recovery partition) and created one for itself.
by using DiskTest tool on ubuntu i recovered some files and full of recovery partition.
after that, for re-install windows 8 from recovered partition , i did set partition bootable by using another tool which was running on ubuntu.
now, windows 8 repair screen appears but im getting -a required device isn't connected or cannot be accessed- error.
i googled about this problem but the solution didnt work for me. (boot change from bios)
by the way , for precaution , i made an IMG file of recovery partition also (which is 14gb).
i tried burn a bootable disk with that image but didnt work because some files in img is too big for fat32.
after that i tried boot from EFI file but bios cant reach to Ntsf part. i tried to explorer IFE file in fat32 but i couldnt because IFE file which i ve is more than 13gb (same problem for fat32 file system)
so summary :
i ve recovery part with files (install.wim , *.ife files...) but getting error.
i ve an .img of partition but couldnt make bootable disk
Maybe there s a tool for reach ntsf then i can boot from ife...i dont know i need ur help.
what can i do?
im really so sad , already i lost many important data, files , pics.. im living in italy and im a student (not italian) and i really cannot order another cd from Hp for recovery.
Im waiting your help.
Thank you.

well, i downloaded windows 8 64bit Enterprise Evl. from microsoft site as says here : http://h30434.www3.hp.com/t5/Notebook-Recovery/Windows-Vista-7-and-8-ISO-Image-file-Download-Links/t...
and i installed without problem..
but before install the system with ubuntu live cd i booted pc and i found my product key which is embedded in bios.
then installed win8 Enterprise 64bit..
now my problem is activation, when i digit the key , before active it, it says under the box it s correct but when i click to active it then im taking the product key you entered will not work with this edition of windows 8 error..
what should i do
thank you

New-Partition assignes driver letter to mount point after reboot.

Trying to create a series of mount points using powershell on Server 2012 R2. When I have used diskpart in the past I could initialize the disk, create a partition, format a volume and assign a mount point without assigning a driver letter to the drive.
When I try to do the same thing in Powershell on Server 2012 R2, everything looks great until I reboot. Every partition I created and assigned as a mount mount gets a driver letter added to it... I am using mount points to avoid drive letters. Is there a way
to prevent this behavior. The following is an example:
Get-Disk 3 | Initialize-Disk -PartitionStyle GPT
Get-Disk 3 | new-Partition -UseMaximumSize -AssignDriveLetter:$False | Format-volume -confirm:$False
Add-Partitionaccesspath -DiskNumber 3 -Partition 2 -AccessPath c:\someFolder
Everything looks good at this point with no driver letter assigned. Rebooting adds a driver letter to the volume with no impact on the mount point... Is there a way to suppress the driver letter assignment?

Figured it out... It appears that this part works fine:
Get-Disk 3 | Initialize-Disk -PartitionStyle GPT
$Part = Get-Disk 3 | new-Partition -UseMaximumSize -AssignDriveLetter:$False
$Part | set-partition -NoDefaultDriveLetter:$True
$Part | Format-volume -confirm:$False
If you look at the output of Get-Partition the NoDefaultDriveLetter value is TRUE. After running Add-PartitionAccessPath it changes to FALSE. You can set it back with the Set-Partition command:
Get-Partition -DiskNumber 3 -Partition 2 | add-PartitionAccessPath c:\SomePath -passthru | set-Partition -NoDefaultDriveLetter:$True
I had a bunch of them to do so I used the following:
Function Config-Disk {
[cmdletbinding()]
Param(
[INT]$Disk,
[INT]$Partition = 2,
[String]$Label,
[String]$MountPoint
Get-Disk $Disk | Initialize-Disk -Partitionstyle GPT
Get-Disk $Disk | New-Partition -UseMaximumSize |
Format-Volume -FileSystem NTFS -NewFileSystemLabel $Label -Confirm:$False
Add-PartitionAccessPath -DiskNumber $Disk -PartitionNumber $Partition -AccessPath $MountPoint -Passthru |
set-Partition -NoDefaultDriveLetter:$True
MD "c:\SomeLocation1"
MD "c:\SomeLocation2"
Config-Disk -Disk 3 -Label "SomeLabel1" -MountPoint "c:\SomeLocation1"
Config-Disk -Disk 4 -Label "SomeLabel2" -MountPoint "c:\SomeLocation2"

Partitioning RAID Master

Oops. Accidentally posted this in the wrong category. Now, I hope it is in the right one...
When I was on OS X 10.3.x server, I was able to mirror my 2 250g HDs and partition the RAID master. It seems I am unable to do that with 10.4.3.
I can partition each drives with the exact same partition table. Then, I try to mirror the partition. I can do that with 1 partition. When I try the second partition, it fails.
They are partitioned thusly:

No errors on this. A diskutil checkraid says that all is online.
So, I issue the command to RAID the next partition:

This isn't a solution to your partitioning problem...
But perhaps you should consider using Disk Quotas.
It's a lot more flexible than having partitions, you can make adjustments as needed where you can't do that with pre-set partition sizes.

Mac Hard Drive Partition

Hi,
I have a iMac OS X 10.4.11. I am wondering if I partition my hard drive (from the disk) will it delete all my data? I wish to make a new partition, of 100gb (I have 230gb of free space), in order to install a Windows operating system. When I go to the partition menu I set up the information and click partition. When I click partition it says that it will destroy all the data... Now I'm wondering if it means that it'll completely destroy the data on the hard drive or its just a message posted incase if I had information of the 100gb of free space. Also... if anyone knows.... If this does destroy all the data on the disk, then why does it? I know what a partition is and I have set partitions up on Windows based computers and had no problems what so ever. I just used free space on the hard drive.... Also I am aware of the buyable programs that I could get so I wouldn't have this problem, but honestly I think this whole situation is ridiculous.

When I click partition it says that it will destroy all the data... Now I'm wondering if it means that it'll completely destroy the data on the hard drive
It says it will destroy all the data, and it means it...!
Disk Utility in Leopard can add a partition to the free space "on the fly," but that feature is not available in Tiger's Disk Utility. There are some third party software that claims to do it. For example
http://www.coriolis-systems.com/iPartition.php
Personally, I don't trust repartitioning without erasing. I always clone (backup) the existing volumes to an external drive, re-partition (erase in the process) the whole drive, then restore by cloning back.
in order to install a Windows operating system.
If you are using Tiger, and you are planning to use Boot Camp for running Windows, Boot Camp was in beta for Tiger. The final release version of the Boot Camp utility is only in Leopard. Also, if using Boot Camp, I believe the Boot Camp utility creates the Windows partition. I don't think you need to (or should) do it separately using Disk Utility.
If you are using Parallels Desktop or VMware Fusion (or other +virtual machine+ program) to run Windows, creating a separate Windows partition is not the best way to install Windows, in my opinion.

Partition name length problem at DML in Table operator

Hello experts
In our datawarehouse we have a table with a high number of partitions (each partition corresponding to a different business object) for solving an issue with data quality. Every time the data quality mapping is run, a truncate on the corresponding partition is performed. But Insert operations on that table are not set on a particular partition and, therefore, lock the table and have a conflict with the truncates if parallel operations are run.
We would like to used the Partition DML functionality at the Table Operator in order to insert just into one partition and prevent locking all of them. Although none of the partition names are longer than 30 characters, OWB (even at the GUI) adds the string "partition: " in front of each name, which causes the length limit to be surpassed.
Any idea about how could we use this functionality without renaming the partitions?

Hey there,
I'm a colleague of the thread starter and like to jump in as this is an issue for us which we need to solve.
Some more infos which might help:
We are running the OWB 11.2.0.3.0 on Windows 32 Bit
We have the following patches installed:
13257502
13473205
None of the later patches has been installed, since none of the Bugs that were fixed affected us.
In a Mapping on a table-Operator we'd like to use "PARTITION DML" for an Insert.
On the GUI when selecting the Partition the data should be inserted to (Field: DML Partiton Name), we get the following error (in this instance the partition name is 24 characters long)
"API0407: The minimum length of this filed is 0 and its maximum length is 32. You have 35 characters."
In the Drop-down Menu of DML Partition Name it says "Partition: " in front of every partition there is. Together with a Partition name of 24 Characters it sums up to 35 characters.
So it appears that the maximum length of the partition is limited to 21 characters only because "Partition: " is put in front of it.
This error also appears when editing the Properties of the table operator by OMB*PLUS (from tcl) with
OMBALTER MAPPING 'mapname' MODIFY OPERATOR 'operatorname' SET PROPERTIES (DML_PARTITION_NAME, DML_PARTITION_TYPE, PARTITION_KEY_VALUE_LIST, IS_PARTITION_INDEXED_BY_NAME) VALUES ('$partition', 'PARTITION', '$someEmptyList', 'true')
where it does not make a difference whether $partition is of the form
set partition "Partition: SOMEPARTITIONNAME"
or
set partition "SOMEPARTITIONNAME"
Renaming the Partitions is not an option for us, since our warehouse is running in multiple productive systems and became quite large in the last years.
Is it necessary, that "Partition: " is put infront of the partition name? Is there a way around this? Isn't the field DML_PARTITION_TYPE supposed to store the Information whether it is a partion or a subpartition?
If you wanted to use subpartitions, does the name of the subpartition then need to be even shorter since "Subpartiton: " is put infront?
Thanks in advance for any help or suggestions. If you need further Information, feel free to ask, I am more than happy to supply it.
Best Regards
Thorsten
