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, ...

Unable to execute Map from Database link

Hi
Been trying to research this issue but have had no luck in finding an answer. Here is the situation:
We have an apex application that resides on database "A"
Our OWB Design Repository (11.1.0.7) and Runtime Environment both exist on database "B"
Maps exists and execute under normal procedures as the "ETL" user on database "B", However we would like to allow the "APEX" user to execute a map from database "A" across a database link to a user that can execute the map without any issue.
When we try to execute the map across the database link from toad or sqlplus we get no error returned, the procedure runs and kicks off a map execution (as seen in ALL_RT_AUDIT_EXECUTIONS) or from the control center executions. However the Map execution immediately fails with no explanation as to why??
what makes even less sense is that the user on database "B" that the database link connects to.. can execute the same procedure all day long if logged directly into database "B".. but the moment you try to call it across the database link.. it errors with no message as to why.
We are calling the "WB_WORKSPACE_MANAGEMENT.SET_WORKSPACE".. so that is not the issue.. I am assuming this is either a bug.. or we are missing an additional call/privilege. The user for the database link is a registered user in the workspace, obviously this works since the database link user can run the procedure if logged in locally to database "B"
Any thoughts???

Figured out our problem..
Found RETURN_CODE column in ALL_RT_AUDIT_EXECUTIONS table.. point to -2064 which is an ora-2064
NOTE 1026597.6 - CALLING REMOTE PACKAGE RECEIVES ORA-2064 explains that a commit is issued in a coordinated session from an RPC procedure call with OUT parameters or function call. Action: simplify remote update statement.
The problem here is that "Commit Control" was set to Automatic for the mappings we were calling. Oracle does not like when a transaction is initiated on database "A" and has a commit issued on database "B" from the map.
Makes sense.. we switched the commit control to "Manual" and are able to process correctly by issuing a commit from the session on database "A"
Hope this helps anyone that runs into this issue themselves..

Unable to find Logical Volume manager in OEL6

Hi Guru's,
I am new to Linux.
I have installed OEL6 in my windows box with Virtual Box.
After logging in
i don't see
the Logical Volume manager
and Network option under Administration menu too.
I tried to install lvm-1.0.8-14.x86_64.rpm (downloaded from redhat) but no luck.
Please help me to fix this.
Thank you
chandra

I remember the Red Hat 6.0 release notes outlining that Samba and LVM configuration GUI were removed without a replacement. Same goes for the system-network-config tool. More recent versions of the release notes at http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/6.0_Release_Notes/storage.html outline that system-config-lvm is in the process of transitioning to a more maintainable tool named gnome-disk-utility.
You did not specify which version of Oracle Linux you installed. I suggest you refer to the release notes. A text based version of "system-config-network" should still be installed, which you can open from the command line.
Regarding LVM gui you should setup the system software repository following the instructions at http://public-yum.oracle.com. You can then use yum to install the system-config-lvm package.

Solaris9 Logical Volume Manager

Dear All,
I want to know more about Logical Volume Manager in Solaris9.
I know that it makes logical volumes from one disk or more?
are these Logical Volumes like a disk can be used for striping datafiles into them if I use RAID 5 controller in Oracle Database?

Linux LVM (Logical Volume Manager) for CentOS on Azure?

Hi. I am trying out Azure and installed a OpenLogic CentOS 6 virtual machine. I note that it is not running LVM (Logical Volume Manager) by default. I would like to ask if it is possible to:
1. have CentOS Linux installed with LVM by default when creating a Linux virtual machine on Azure
2. switch to LVM after adding a new disk
On the other hand, is it a good idea to use LVM at all? Will it affect performance, features on Azure?
Thanks.

Hi,
Based on my experience, you can add disk to an Azure VM. You can install the Logical Volume Manager to manage the disks attached to the VM. In addition, there is no Linux VM with LVM installed by default. If you want to have this, please submit your requirement
in Azure feedback:
http://feedback.azure.com/forums/34192--general-feedback
In addition, since you can have only one OS system disk for an Azure VM, this limitation may make multi-disk logical volume manager setups unworkable.
Best regards,
Susie

Hi all,
Thanks for your response, and sorry for wrong question here i need to supply default values to column of
table based on input file so default values of columns will be changed based on input file, and one more thing i don't have any rights to change the table structure my work is to load data from file to table. Is there any chance to supply default values by XMLformat
file instead of .fmt file
or any other scenarios please let me know the possibility.

How to find largest number from text file

I am using the "Read from text file" block to read the data from my .txt file into labview. It is now in string format. I have many numbers in the file.
For example:
0.45
0.35
0.12
1.354
1.56
2.89
5.89
0.56
That is what a text file might look like. I want to find which of these numbers is largest, and do calculations with that number. I am having trouble with strings/number formats/arrays, etc. Thanks
Solved!
Go to Solution.

The spreadsheet functions and VIs typically work on strings representing numbers separated by delimiters. This is a typical way to save a "spreadsheet" (of numbers) to a text file, for example .csv files. These are quite versatile and powerful functions. Spend a bit of time becoming familiar with them because you may find yourself using them a lot.

How to define mapping from multiple files to Oracle Tables in 9i

Around 100-200 Flat files are created every 30 minutes and each filename is different - Filename has datetime Stamp as part of the file name apart from the product code as first 12 characters.
Can anyone guide me in How to define mappings to these files using OWB ?
What I can do is consolidate all files into one known single file name and map the files to Oracle tables which I don't want to do because I need to reject errorneous files.
Can anyone provide me some tips on this ?
Thanks in Advance.
Sohan.

As you know, in OWB you need to define the flat file source in a 'static' way (name, location, etc. have to be defined previously), so you cannot deal directly with dinamically generated file names. One solution would be to consolidate them into a single file (which you can define statically in OWB), but prefix every record with the filename. In this way it is easy to understand from which file the rejected records came from. If you are using unix, it is very easy to write a script to do this. Something like this will do:
awk '{printf "%s,%s\n",FILENAME,$1}' yourfilename >> onefile
where yourfile is the name of the file you are currently processing, while onefile is the name of the consolidated file. You can run this for all files in your directory by substituting yourfilename with * .
You can then disregard the file name field in OWB, while processing the rejected records based on the file name prefix by using unix utilities like grep and similar.

Logical Volume Manager

I am planning on installing Arch on a laptop soon. I have played with it in VirtualBox on a separate computer, and I am going to hope that it works with my touchpad / wireless mouse.
I might butcher some jargon in this, but this is how I think LVMs work, and I would like to make sure.
I am going to make partitions for boot, swap, /, and /home.
I know boot only needs to be around 100MB, swap is twice the RAM -- and I saw in another thread, / around 10-15GB -- and /home is the rest.
However, I read about installing on an LVM and it is easy to re-size partitions if needed.
I only have 1 HD, and I'm mostly doing this because while I do have room to have too much space on /, if I end up only using around 4GB, I would like to have that 11GB on my /home for music or videos.
So I think that means I would have something like this:
sda1: boot, around 100MB.
sda2: LVM, which contains swap, /, and /home.
pvcreate /dev/sda2 creates the physical volume on the LVM, allowing me to partition it.
After that, this is where I am confused.
The Arch Wiki says:
Create Volume group(s)
Next step is to create a volume group on this physical volumes. First you need to create a volume group on one of the new partitions and then add to it all other physical volumes you want to have in it:
# vgcreate VolGroup00 /dev/sda2
# vgextend VolGroup00 /dev/sdb1
Also you can use any other name you like instead of VolGroup00 for a volume group when creating it. You can track how your volume group grows with:
Can I skip this since I have only 1 HD? I guess that /dev/sdb1 is the LVM from the other harddrive?
I suppose I would have to do vgcreate VolGroup00 /dev/sda2 just to create the volume goup, though. Is this correct?
After this step, I am pretty much lost. Here's what the wiki says, and how I am interpreting it...
# lvcreate -L 10G VolGroup00 -n lvolhome
This will create a logical volume that you can access later with /dev/mapper/Volgroup00-lvolhome or /dev/VolGroup00/lvolhome. Same as with the volume groups you can use any name you want for your logical volume when creating it.
So later, I would turn this into my home partition during the Arch installation? I would create a lvolswap, and a lvolroot?
Then, during the installation process, I would format them to ext3, and mount them as /home, /, and then select lvolswap as my swap partition?
That's about it for now, I guess.

If I put GRUB on /boot, it doesn't work, but I got it to work if I installed it on the / LV.
odd, to my knowledge grub can't be on an LVM. why not install grub on MBR?
I actually figured this out maybe an hour ago.
I changed my GRUB configuration file, but since it's in a virtualbox, out of habit I type arch root=/dev/sda3 on startup, but I needed to type root=/dev/VG00/lvolroot. I had grub on /boot (not on the LVM), but when I was trying to boot, I told it to go to the wrong place for root. I could probably unmount the .iso for the vbox, but whatever.
I will read a little more about RAID.
If I end up figuring out how to do it, would I need my external hooked up to it all the time? I have tote the laptop around, and I wouldn't want the external mucking up the portability.
I wasn't aware you were on a laptop. In that case, a file server would do you best. But cheapest solution would be just to stick with an external hard drive and not RAID.

Dynamically add data points to U.S. Map from excel file?

Hi,
I have an illustrator U.S. map and I have an excel spread sheet with 1,000's of zip codes. I need to add dots on my map for each zip code. How do I do that dynamically? This is going into an annual report so the design needs to be kept in Illustrator and the dot style needs to be adjustable.
Please let me know if there is a solution as opposed to manually looking up the zip codes and copy/pasting 1,000's and 1,000's of dots.
Many thanks in advance,
Stacy

Not sure I follow exactly what you have in mind. You just want to have a dot at the location of each zip code on a map of the US? Are the dots going to be individually labeled? Individually named objects? Isn't there something like 40,000 zip codes in the US?
You don't provide much information about the problem. What kind of map? Does it already have individual objects drawn in the shape of zip codes and you just want a dot in the middle of each? Are you literally just starting with an outline of the whole US?
What kind of columns are in your spreadsheet? For example, do you have latitude/longitude data cells for each zip code? I don't think there is any geographical reference system embedded in a zip code. It's just a number.
Illustrator isn't going to recognize a *shape* as the state of Georgia, for example, unless that object already has some kind of identifier within Illustrator. So obviously, you would need some kind of 2D reference table to tell whatever automation scheme you employ where to place each dot on an XY coordinate grid.
Such things are available, as described here:
http://www.maponics.com/index.html
I suspect you're probably trying to reinvent the wheel here, but it would not be a difficult Javascript problem, once armed with the three-field data. This would be the general scheme:
1. Start with a data table with three columns: Zip Code, Latitude, Longitude.
2. Write an AI Javascript which does these things:
-Contains a function which uses a simple multiplication scheme to effectively scale the Lat/Long values into X and Y divisions of your Artboard area.
-Contains a loop which cycles through the Lat/Long values, calls the function to translate each into X/Y page coordinates, and places a pre-defined Symbol (an AI Symbol, in the sense of the Symbols Palette) at each coordinate pair. Using Symbol Instances would enable you to use the various Symbols-related commands to later globally swap out or edit the symbols.
-The script could optionally name each of the instances by its zip code, if necessary.
3. After running the script, simply scale and position the map (probably on an underlying Layer) proportionally so that two points on it correspond to any two known lat/long coordinates. The rest of the map would then correspond to the dots on the grid.
But again, I strongly suspect this has all been done before. You could probably buy a vector graphic file like what you need from a map clipart source and then just edit it stylistically for your use.

Finding taglib's from war files

          Within a war file, I have a jsp which lies within a directory called /phase1 underneath the document root,
          containing the line:
          <%@ taglib uri="../xlab-taglib.tld" prefix="xlab" %> (1)
          which is saying that the taglib is in the directory above, which is the document root. So when
          xlab-taglib.tld is in the document root, everything works fine on JRun & Tomcat, but on Weblogic,

Itunes can't find my music from old file

Although my music is available on my ipad and phone, Itunes can't find and play my music on my laptop. WTH?

+changed the location of the music folder to E: iTunes Music.+
All this does is make future additions go to that new place.
When you move things around outside of itunes, it loses the path, as you've found.
Can you move everything back and use the Consolidate Library command to move it to the new location?
Here is a good article from iLounge on what you need to understand about the process.

How to query data from database and store it into Managed Bean ?

Hi all,
In our application we have requirement to store information within Managed Bean to be accessed by ADF pages.
The information is stored in database tables.
The question is :
What is the efficient / recommended way to do that ?
I do not use apps module to query the data because the information is required in View layer not the model layer
Thank you for your help,
xtanto

Xtanto,
if the information is stored in the database then the question is if there is a database connect open already. If yes, then why not using this connection to query for the data you want to access and store. Alternatively you can directly open a JDBC connection in a managed bean or access an EJB session bean. However, this comes with the price of an extra database connection.
Make sure the managed bean is in session scope if you want to share the information without re-fetching it
