Identifying the Logical Partition
Hi Team ,
Please clarify, how we can identify the Logical disk name in Solaris OK prompt (like c0t0d0) using the physical name.
Regards,
R. Rajesh Kannan.
do you have scsi drive or ide
try this
ok probe-scsi-all
ok probe-scsi
or
ok probe-ide-all
ok probe-ide
ok test all

How do you identify the Logical system in start routine of a transformation
My scenario is this. I have five r3 systems that I am extracting from. In the start routine of the transformation from the r3 data source to my data store I am going to delete data and I need to know the source system id. How do I identify the logical system or source system id in the transformation. Is there a system field that contains this information. I do not want to hard code the source system id in the routine.
hi
have a lool at tables rsreqdone and rsbkrequest with a join you should be able to determine the source.

DB6 - Supports the logical partitioning for SAP BW
Hi All,
Please can someone help me to give the information .
We are using DB6 on top of that we have SAP BW 7.0. Is the logical partitioniong supported with this DataBase.
Thanks
kapseHi Kapse,
By using partitioning you can split up the whole dataset for an InfoCube into several, smaller, physically independent and redundancy-free units. In SAP BW you can achieve the same as
In the InfoCube maintenance choose Extras ® Partitioning, and specify the value range. Where necessary, limit the maximum number of partitions. Note: You can only change the value range when the InfoCube does not contain any data.

Command or script to identify and delete the bitlocker partition
I am looking for some command or script to identify the bitlocker partition and delete it. Please let me know if anybody has any suggestions.
Hi,
I just want to know why you want to delete the BitLocker partition? If you mean the system reserved partition, it is not recommended to do like this, this partition contains not only the BitLocker component, but also the boot files. Deleting it would lead
into system startup failure.

Resizing a logical partition with a LUKS container
I have a logical partition that contains LUKS which holds an LVM2 schema. My goal is to resize the existing logical partition so I can create other partitions in their own LUKS-encrypted container. So far, the LVM2 PV is resized and I'm looking for advice on how to handle shrinking the LUKS container and the logical partition it lives on.
I heard rumors that LUKS containers don't need to be resized and that I can change the size of the block device it lives on without problems. Is this true? If so, it seems like I should be able to delete the logical partition and replace it with a smaller one as usual. How can I calculate the blocks/sectors/etc for the new partition with the LUKS & LVM2 data on there?

Finding whole mapping from database file - filesystems - logical volume manager - logical partitions
Hello,
Trying to make reverse engeneering of database files and their physical carriers on logical partitions ( fdisk ).
And not able to make whole path from filesystem down to partitions with intermediate logical volumes.
1. select from dba_data_files ...
2. df -k
to get the listing of filesystems
3. vgdisplay
4. lvdisplay
5. cat /proc/partitions
6. fdisk /dev/sda -l
fdisk /dev/sdb -l
Problem I have is that not able to determine which partitions are consisten in logical volumes. And then which logical volumens are consisted in filesystem.
Thank you for hint or direction.Hello Wadhah,
Before start the discussion let me explain I am newcommer to Oracle Linux. My genetic with dba experience of Oracle is from IBM UNIX ( AIX 6.1 ) and Oracle 11gr2.
First task is to get the complete picture of one database on Oracle Linux for future maintenance tasks and make database more flexible and
preparing for more intense work:
-adding datafiles,
-optimize/replace archive redolog files on separated filesystem from ORACLE_BASE
- separating auditing log files from $ORACLE_BASE to own filesystem
- separating diag directory on separated file system ( logging, tracing )
- adding/enlarging TEMP ts
- adding/enlarging undo
- enlarging redo for higher transaction rate ( to reduce number of switched per time perceived in alert_SID.log )
- adding online redo and control files mirrors
So in this context try to inspect content of the disk space from the highest logical level in V$, DBA views down to fdisk partitions.
The idea was to go in these steps:
1. select paths of present online redo groups, datafiles, controlfiles, temp, undo
from V$, dba views
2. For the paths got from the step 1
locate filesystems and for those filesystems inspect which are on logical volumens and which are directly on partitions.
3. For all used logical volumes locate the logical partitions and their disks /dev/sda, /dev/sdb, ... -
0IC_C03 related Inventory Process - Logical Partitioning (Vs) Physical Part
Hello Everyone,
After going through multiple postings throughout the form and documentation from SAP, it states that the 0IC_C03 InfoCube when used with Non Cumulative keyfigures is not recommended to be partitioned logically by physical year/calendar year as the query will read all the data sets due to the stock marker logic.
In our specific scenario,
1. After the InfoCube (0IC_C03) was enhanced with additional characterisitcs such as Doc Number, Movement type and so on due to business requirements I was not able to actually use the Non Cumulative Keyfigures as they were not populated within the report.
2. So, we decided not to use the Non Cumulative keyfigures but rather create two cumulative keyfigures (Issue Stock Quantity - Receipt Stock Quantity) and (Issue Valuated Stock Value - Receipt Valuated Stock Value) and both of these are available in the InfoCube and are calculated during the update process.
These two keyfigures are cumulative with exception aggregation of LAST based on 0CALDAY.
The question is,
Since we are not using the actual Non Cumulative Keyfigures (even though we are not using these, we still have the stock marker updated and data compressed based on this along with Validity table defined) can we do logical partitioning on the InfoCube based on Calendar year.
Thanks....Hello Elango,
Appreciate your response.
First of..I do understand the difference between logical and physical partitioning and the question is not about joining them together.
I am sorry, if others cannot understand the detailed issue posted. My apologies was a part of polite gesture, and please do respond back with proper precise answer if you think you did actually understand the question....
The question here is about how I can leverage the performance and administrative performance by logically breakingdown the data.
The issues due to which I am trying to look into different aspects of logical partitioning are:
1. If I do logical partitioning by Plant due to the stock marker logic then I cannot do archiving as a Plant and its related data cannot be archived by time characteristic as the partitioning is not done by time characteristic.
2. The reason I would have to have document number and movement type in the InfoCube is due to the kind of reporting users perform.
We have a third party system whose data needs to be reconciled to the data in the plants and storage locations.
And in order to do so, the first step users would be running the report is plant, storage location and sku. From here on for the storage locations which have balance they would like to drill down on to the document number and movement type to see what the actual activity is.
So, to support this requirement I would have to have the above characterisitcs in the InfoCube.
The question again is,.....what is the exact list of issues I would be having doing the logical partitioning by time characteristic.
Once again, even though the non cumulative keyfigures are available in the InfoCube we are not using them for any reporting purpose....so please keep that in consideration while replying back.
Thanks

Erase "Logical Partition Group" Partition
Hi guys,
I have a 3 TB drive of which I've partitioned into (3) 1 TB volumes. 2 of them read Mac OS Extended Journaled and 1 reads Logical Partition. Is it possible to erase the Logical Partitioned volume, have it read Mac OS Extended Journaled, while keeping the other 2 in intact, with all it's info? For some reason, this happened when I was Carbon Copy Cloning the Marverick drive to 1 of these volumes.
Thanks,
CLYes - Disk Utility - select the partition and erase it with the Mac OS Extended Journaled. Hit the Option button and select GUID.

Trying to run from logical partition - GRUB doesn't detect it
Hi all, I only have a single SSD in my laptop with the following setup (in order on disk):
sda1 - System Reserved
sda2 - Windows 8
sda4 - Extended Partition
sda5 - Arch 2 (this is where I'm trying to move my Arch install to)
sda3 - Arch (this is the one I can actually boot into
(unallocated space)
This is what I want things to look like eventually:
sda1 - System Reserved
sda2 - Windows 8
sda3 - Extended Partition
sda4 - Arch
sda5 - some other distro
sda6 - storage (I want this accessible by all OSes)
Here's how I think I'm going to do this:
- move Arch installation from after the extended partition to before it (since the extended partition is a big chunk of mostly free space, and I would like it to go last.
- after verifying that I can boot the Arch installation from the logical partition, delete the Arch installation on the primary partition and absorb the free space into the extended partition
Here's what I've done:
- used 'dd if=/dev/sda3 of=/dev/sda5 bs=4096 conv=notrunc,noerror' to clone my working Arch installation to the logical partition (sda5).
- ran 'grub-mkconfig -o /boot/grub/grub.cfg' to update GRUB and add the logical partition to the list of things to choose from in the Grub menu.
After running 'grub-mkconfig' nothing new was added to the menu.
Questions:
- Is what I want to do even possible?
- can I have the logical partition marked for storage be accessible to Windows 8?
- Is there an easier way to do what I want to do?
- How do I get GRUB to detect the logical partition?
- Is it possible to boot into a logical partition?grub doesn't always automatically pick up arch installations. Is os-prober installed? You can always add the entry manually e.g. in 40_custom or whatever. Don't forget to adjust fstab.
Just to be clear: you have an MBR formatted disk and are talking about traditional logical partitions, right? Not lvm?

We have 2 logical partitions separated in 2 different physical m/c where cluster of forms /reports is installed.
if i have a report service repsrv11g on one logical partition say, box 100 on Physical box 6000, the other logical partition box101's forms server on physical box 7000 is not able to look up the report service when calling from Forms using the Run_report_object.
Gives, FRM -41213 error.
If i just run the URL(use 2nd box) with http://101:8888/reports/rwservlet/showjobs?server=repsrv11g, it gives REP-51002: Bind to Reports Server repsrv11g failed
We thought/read that as long as they re on the same network / domain, report service is available.
Also did rwdiag.sh on one partition, its not able to find the other one.
Ran the test form which Oracle provides and it s also not able to find the report server on the network when run on the other lpar.
Temporarily, we created another report service on the other lpar but still using loadbalancing dns while doing web.show_document, so, it could potentially fail to bring up a report if load balancer redirects from one form's server to report server on the other partition.
Any thoughts would be greatly appreciated.

I have purchased a mac mini only to find I am unable to run Logic pro 9 , is there any way this can be achieved? It has been suggested that I partition the drive and install a copy of an older operating system to run the Logic Pro, is this feasible?
BDAqua wrote:
....but some other new Macs will boot frome a clone of 10.6.8...
Only with a whole lot of effort and instability. As the new Minis have
hardware (HD4000, USB 3.0, etc.) that is totally unsupported in old OSes.
The only option would be to see if it would work by installing in a virtual machine
running 10.6.8. I'm sure there will be some performance hit but whether it would
be enough to be unusable is the question. -

R&R - how is the system partition identified?
When trying a full restore of the system partition only (from a backup stored on a network share, selecting "recreate full system" and threafter checking "system drive only"), I get a (German) error message, saying something like
"... the system partition does not exist or could not be found".
Since my R&R backups were created when my notebook was configured with many partitions (linux and windows), the partition scheme in the master boot sector was different. Now I would like to restore the system partition into the C: drive (partition "Windows7_OS") but this partition is not found by R&R. Does anone know how R&R looks for the system partition? If I would know what attributes such a partition needs to have, I could probably "fake" such a partition and R&R would restore my files...I've read your posts. R&R has a limitation that the partition structure of the disk cannot change after you start taking backups. I think at this point, your only hope of recovering your backups is to start with a completely blank HDD (no partitions) that is as big or bigger than your original HDD. This will put R&R into a different mode called "bare-metal" where the partition structure, in addition to the contents, are restored. The way you are doing it now, R&R is trying to restore the contents only, but since the partition structure has changed, this is apparently failing.
Anyway, try using a completely blank HDD and restoring your backup that way. I think it's probably your only hope. -
Logical Volume Group and Logical Partition not matching up in free space
I was dual booting Windows 7 and Mountain Lion. Through Disk Utility, I removed the Windows 7 Partition and expanded the HFS+ partition to encompass the entire hard drive. However, the Logical Volume Group does not think that I have that extra free space. The main problem is that I cannot resize my partition. I am wanting to dual boot Ubuntu with this. Any ideas?

Logical partitioning, pass-through layer, query pruning
Hi,
I am dealing with performance guidelines for BW and encountered few interesting topics, which however I do not fully undestand.
1. Mainetance of logical partitioning.
Let's assume logical partitioning is performed on year. Does it mean that every year or so it is necessary to create additional cube/transformation and modify multiprovider? Is there any automatic procedure by SAP that supports creation of new objects, or it is fully manual?
2.Pass- though layer.
There are very few information about this basic concept. Anyway:
- is pass through DSO write optimized one? Does it store only one loading - last one? Is it deleted after lading is sucessfully finished (or before new load starts)? And - does this deletion do not destroy delta mechanism? Is the DSO replacing PSAfunctionally (i.e. PSA can be deleted every load as well)?
3. Query pruning
Does this happen automatically on DB level, or additional developments with exits variables, steering tables and FMs is required?
4. DSOs for master data loads
What is the benefit of using full MD extraction and DSO delta insetad of MD delta extraction?
Thanks,
Marcin1. Mainetance of logical partitioning.

Logical partitioning is when you have separate ODS / Cubes for separate Years etc ....
There is no automated way - however if you want to you can physically partition the cubes using time periods and extend them regularly using the repartitioning options provided.
2.Pass- though layer.
There are very few information about this basic concept. Anyway:
- is pass through DSO write optimized one? Does it store only one loading - last one? Is it deleted after lading is sucessfully finished (or before new load starts)? And - does this deletion do not destroy delta mechanism? Is the DSO replacing PSAfunctionally (i.e. PSA can be deleted every load as well)?
Usually a pass through layer is used to
1. Ensure data consistency
2. Possibly use Deltas
3. Additional transformations
In a write optimized DSo - the request ID is key and hence delta is based on request ID. If you do not have any additional transformations - then a Write optimized DSO is essentially like your PSA.
3. Query pruning
Does this happen automatically on DB level, or additional developments with exits variables, steering tables and FMs is required?
The query pruning - depends on the run based and cost based optimizers within the DB and not much control over how well you can influence the execution of a query other than havin up to date statistics , building aggregates etc etc.
4. DSOs for master data loads
What is the benefit of using full MD extraction and DSO delta insetad of MD delta extraction?
It depends more on the data volumes and also the number of transformation required...
If you have multiple levels of transformations - use a DSO or if you have very high data volumes and want to identify changed records - then use a DSO.
