How to create Mount Point in Linux
Hi,
I m new to Linux OS, want to install Oracle EBS R12 on OEL 5.6 . I have downloaded s/w and installed all required packages for OEL.
Now i want to create Staging directory at location /u01/StageR12.
Can anyone guide me for how to create Mount point /u01 and how to assign space of 53 GB to it.... ?
Reply awaited...
You're on the right path.
Keep in mind though what you need partition wise just for o/s install. You should have at least 3 partitions:
- a ?? GB partition for the / (root) mount (the size depends on what you will install and how much space you will need for running that s/w)
- a 128MB or larger partition for the /boot mount
- a ?? GB partition as swap space mount (typically rule of thumb is 2x RAM for 4GB and lower, else around 25% of total RAM)
I would not create separate partitions for the old-style +/u01+ mount points for Oracle. That part of the OFA (Oracle Flexible Architecture) standards are old and pre-ASM and pre- automated Oracle managed data files.
You need space for installing an Oracle Home. I do not see the need for a dedicated mount point for that. I use the root file system.
You need space for the actual database. If you use Oracle ASM, then I would create raw partitions (across disks) to be used for database storage. These will not be mounted or formatted. Instead these will be assigned to an ASM diskgroup (and striped by default) and used for database storage.
If you do not use ASM, then you need a cooked file system for storage of database file. In that case separate mount point(s) make sense. Also, it makes sense not to manually apply the old OFA standards, but instead use Oracle managed database files. In that case you need a single mount point (e.g.<i>/oracledb</i>) - and set that as the base directory for Oracle to use for the database. Oracle will create an OFA compliant database directory tree and files under that base directory/mount point.
Keep in mind that the more mount points you have for the database, the more difficult your job becomes to manage storage. The easiest is a single mount point for the database and using Oracle to manage the OFA compliant side for you on that mount point.
Also, you cannot and should not attempt some kind of manual striping layout of the database across multiple mountpoints. This may have made some sense back 10+ years ago. It no longer does.

How to create mount point from external drive directory
Hi,
Is it possible to create a mount point pointing directly to an external drive directory?
For example I would like to have /Volumes/Media point to my external eSATA drive /eSATA/Media
What I am trying to achieve is that I can see a virtual drive in Finder called "Media"
This is important because when this external drive is connected on my NAS Server the /eSATA/Media directory
shows up as a mounted drive called "Media" alse (through afp).
What I want is to see "Media" pointinf to /eSATA/Media regardles if it is connected directly to my MacBook or connected on my NAS.
Thanks for your help.

Hi guys.
How to create mount point for database .
Thanks.Even if you tell us the operating system your system may use another file system provided by another company separate from the OS so information about file system software would help us as well. JFS UFS VERITAS........
I presume your talking about "mount points" because you need another file system for this restore. Your Unix admin should be able to help provide extra disk capacity?
Kind regards -
Creating Mount Points using XML
I am new to xml and am trying to create mount points using xml.
However, I am having trouble figuring out what tag to use to set
the Associated Folder. There is an AssociatedPublicObject
attribute for mount point that using that as a tag doesn't work.
Can anyone tell how to do this?
Thanks.It is possible using only XML, yet I am missing the mount point path...
my XML sofar is:
<?xml version = '1.0' standalone = 'yes'?>
<MountPoint>
<Name>testMountP</Name>
<Description>Test Mount Point</Description>
<Acl Reftype="Name">Lesezugriff_fuer_Projekt_Mitglieder</Acl>
<SecuringPublicObject Reftype="Path"> /mypath </SecuringPublicObject>
<ResolvedPublicObject Reftype="Path"> /mypath </ResolvedPublicObject>
<ASSOCIATEDPUBLICOBJECT Reftype="Path"> /mypath </ASSOCIATEDPUBLICOBJECT>
</ObjectList>
Somehow the attribute AssociatedPublicObject does not get updated by this xml. The MountPoint is created but the location path is set to null.
Any comments? -
How to create restore point in windows server 2008 service pack1
hi i am bhaskar ... how to create restore point in windows server 2008 service pack1 and how to restore system from a restore point in windows server 2008 service pack1.. is this option available or not ? what is the difference between shadow copies and
restore point ? instead of restore point we have this shadow copies option in windows server 2008 ?BhaskarAFIK, Restore Points doesn’t exist in Windows 2008.
Volume Shadow Copy option can be used to achieve:
Creating consistent backups of open files and applications
Creating shadow copies for shared folders
Creating transportable shadow copies using a hardware provider — for backup, testing and data mining scenarios
Quickly recovering and restoring files and data
It is more like a file, data, application backup.

How to create watch points in ECC 6.0
Hi Experts,
How to create watch points in ECC 6.0
Thanks.Dear Kalyan,
The moment the debugger starts, there will be an icon for "Watchpoint" exactly after F5, F6, F7, F8 and a big STOP red button on the application tool bar. Once you click on that Watchpoint button, it will take you to the screen where you need to define the exact field and its relative operator along with the condition to be checked.
Hope this is clear. No navigation needed for this.

Create mount point on Mac OS for Oracle 10g
I am trying to install Oracle 10g on Mac OS. The current mount point is "/". But I want to create a mount point like "/u01" so that the Oracle home path will be /u03/app/oracle. The question is how to create this mount point /u01 on MAC OS? Please advise.
Thanks
S.Mount points are traditionally simple (and empty) directories.
A directory becomes a mount point when it is used in the mount command. Typical *nix sequence is
mkdir /u01
mount <type information> <source disk> /u01 -o <options>
What the docs are referring to is the Oracle (or Optimal) Flexible Architecture and the assumption is that you have additional drive partitions available. In that case
mount -t ext3 /dev/sdb1 /u01
would do the trick.
In your case, assuming you have enough disk space on the root file system, and assuming this is not for a production environment, just stop at the 'mkdir /u01' and you;ll be fine. Then 'mkdir -p /u01/app/oracle' and 'chown -R oracle:oinstall /u01' so that you can use '/u01/app/oracle' as your ORACLE_BASE in the install, and '/u01/app/oracle/product/11.1.0/db_1' as the ORACLE_HOME (which will become the defaults if you set ORACLE_BASE=/u01/app/oracle before you start the installer)
For a production system, it is generally insane to use one disk and put Oracle database & s/w on the root disk - 'eggs in one basket' kind-a thing. -

How to create bullet points in BoilerPlate 'Text' item...
Hi,
I have a requirement of generating a form. In that form there is a static section which contains bullet points. Is there a way to create bullet point in oracle reports.
I am using paper layout. As output is required in PDF format.
ThanksHi Arshad
You may try this trick to introduce bullet character in Reports on Windows platform:
For Boilerplates:
In Application such as Wordpad, hold Alt and press 0149 on numeric pad. This will insert a bullet mark in the editor. Copy this text and paste it in Reports Paper Layout.
For Fields:
Create a formula column (Character type) in the same group as the column that you need to bullet. Return the following result:
return '� ' || :<your_column>;
All the values based on this Formula column will display a Bullet mark.
Hope this helps.
p.s. character 149 is bullet character in most fonts.
Regards

How to create another instance on linux without using dbca?
I have an oracle database (or instance) named viton1 on my linux.
Now I want to create another instance (or database) named viton2 on my linux without using dbca.
I know I can create a database by runing a sql script : create database ......
But my problem is:
before I can run the script for create database, I must startup nomount database.
Before I can startup nomount the instance, I have to connect the instance.
So I do it:
$sqlplus /nolog
sql > conn sys/password as sysdba;
sql >
then I connected to viton1, that's not what I expected.
In order not to connect to viton1, I set ORACLE_SID=viton2. Then it show error: insufficient privilege.
Who can tell me the right way to create another database without using dbca?
Thanks in advance.In $ORACLE_BASE/admin you should have a directory structure for the viton1 instance : create a similar directory structure for the viton2 instance.
In the pfile subdirectory create the initviton2.ora file : you can copy it from initviton1.ora file and change all occurrences of viton1 to viton2.
At OS prompt : export ORACLE_SID=viton2, then
sqlplus /nolog
conn / as sysdba
startup nomount pfile=$ORACLE_BASE/admin/viton2/pfile/initviton2.ora
then CREATE DATABASE..... -
How to create a database on linux
Good day friends Oracle forum, I started with Linux and have installed on a linux server with the Oracle 10g installation wizard, now my question is how I believe the database in windows did so through the wizard and configure all linux data but do not know how Algueña can help me with this step.
Very gratefulHi,
Have you able to run DBCA successfully?
If not kindly post the LINUX version in which your have installed oracle and also confirm that you did not got any error during your installation. It seems that you have missing prerequisite rpm.
Thanks,

You can delete it from itunes and sync.
You can deselect it from the apps tab and sync.
You can hold an icon on the iphone until they all wiggle then tap the "X".
You cannot delete the standard app.
Maybe you should have a look at the manual. -

I want use c++ codes on linux real time. For testing reasons I want to have a function that adds 2 values and gives the result.
I've done these steps:
1. writing a c++ file in Eclipse (see screensot 2)
2. building a shared library (.so) from my c++ project in Eclipse (with Cross GCC)
3. putting this file on myRio (path: /usr/local/lib/)
4. creating a VI that calls this library from Labview with a "Call Library Function Node" (see screenshot3)
5. Setting the properties for the "Call Library Function Node" (see screenshots 4-7)
After I run this VI i get this error message: LabVIEW: (Hex 0x627) The function name for the ... node cannot be found in the library. To correct this error, right-click the Call Library Function Node and select Configure from the shortcut menu. Then choose the correct function name. (see screenshot1)
I've tried a lot things to solve this problem but I couldn't find a solution. Would be very happy if anyone can help me. I guess that I have to edit my c++ code to export my function (symbol). But I have no idea how to make it. I also tried it with a dll file in the same folder but it didn't help.
Perhaps someone can send an example which works on myRIO.
Thanks!

screenshot7can see it in the screenshot8 there is a function called "_Z8AddierenddPd" instead of "Addieren". I copied this name to Labview (see screenshot9) and it worked.
I'm sure that there is a way to compile the shared folder with gcc without decorations (mangling). But I don't know how. If someone has a recommendation I would be very glad!
Prepend each function declaration that you want to be available without name decoration with
extern "C" <your function declaration>
Or if you have multiple functions you want to export you can in the header file where you declare your functions simply use:
#ifdef __cplusplus
extern "C" {
#endif
<all your function declarations>
#ifdef __cplusplus
#endif
