Question on IDENTIFIED EXTERNALLY clause

Oracle Version      : 11.2.0.2
Platform : Solaris 5.10
Just going throug the basics of IDENTIFIED EXTERNALLY clause. If i create a user named app_user as shown below, how does this user connect to the DB and create a table in this schema. Do i have to create Unix user account for this DB user?
create user app_user identified externally;
grant create session to app_user;
grant create table to app_user;
SQL> show parameter authent
NAME                                 TYPE        VALUE
os_authent_prefix                    string      EXT$

Hi;

User identified externally

I downloaded and installed Oracle Ex on Windows XP Professional SP 2 taking all of the defaults and all when swimmingly. Then I used sqlplus to create an externally identified user. The user was created. However if I enter "sqlplus /" to connect as the user I get
ORA-01017: invalid username/password; logon denied
This same procedure works under Linux. How do I get it to work under Windows?
Thanks,
john

Creating External users in Oracle
For example, consider the following user definition:
CREATE USER OPS$SCOTT IDENTIFIED BY TIGER;
Assuming that Scott has logged onto the operating system, Scott could enter SQL*Plus with or without a password:
sqlplus /
sqlplus scott/tiger
You can also create the user with the "identified externally" clause:
CREATE USER OPS$SCOTT IDENTIFIED EXTERNALLY;
Create Oracle External users in Windows
External users are easy to create in Linux because you need only create the user in /etc/passwd. It's a bit trickier in Windows:
1. Create the Windows user:
start --> settings --> control panel --> administrative tools --> computer management --> user
2. Add the new user to the Oracle group:
start --> settings --> control panel --> administrative tools --> computer management --> groups
3. Add user to OS Database Administrator:
start --> programs --> oracle home --> configuration and migration tools --> administration for windows NT --> OS database administrator
4. Add user to OS Database Operators:
start --> programs --> oracle home --> configuration and migration tools --> administration for windows NT --> OS database operators
5. Add user to OS Administrator:
start --> programs --> oracle home --> configuration and migration tools --> administration for windows NT --> OS administrator
6. Add user to OS Operators:
start --> programs --> oracle home --> configuration and migration tools --> administration for windows NT --> OS operators
7. Add os_authent_prefix=OPS$ to your initialization parameters (pfile or spfile) and bounce Oracle database, if necessary.

Connecting with java2 1.4 & user identified externally

Hi,
I try to connect to the Oracle DB 8.1.7. in my java-program (url : <
jdbc:oracle:oci8:@ >) with a user that is identified externally (OS-unix
SUN) . The version of java2 is 1.4
My java-connection work correctly with the Oracle jdbc-driver
"classes12.zip" in my CLASSPATH.
But is NOT work with the last jdbc driver of Oracle "ojdbc14.jar" in my
CLASSPATH. I assume that I have to install also the OCI shared
libraries. But which version of the OCI libraries : 9.2.0.1 or 9.0.1 or
8.1.7 ? Can I use the OCI libraries 9.* for a connection to Oracle
Database 8.1.7?
Other question: is it possible to connect with a user identified
externally with the thin driver?
Kind regards,
Kristoffel DE GEEST

I cannot see any clue in the java API doc. (Using 11g & Java 1.6.30)You connect as a user,
you provide the password for the user using setPassword(),
as in this example;

SSO and Form 10g, Setting RAD of OID for DB users identified externally

Please Help!
Current environment:
- All users were created with identified externally in Database (OPS$)
- SSO was setup correctly according to OID admin guide Ch 43 and SSO admin guide ch 8 for App10g. (user login orasso without seeing basic auth/sso login form)
- DB parameters:
remote_os_authent=TRUE
os_authent_prefix=' '
issues:
- set ssoDynamicResourceCreate = true
When user hit the form link, i.e. http://host:port/forms90/f90servlet?config=test&form=appwelcome
it redirects to http://host:7777/oiddas/ui/oracle/ldap/das/mypage/AppCreateResourceInfo?...
where it shows Resource Name TEST and prompts username/password/database
when user inputs window logon /password/database value (same as in form6i)
it returns ORA-01017: invalid username/password; logon denied.
- set ssoDynamicResourceCreate = false
manually set RAD for the end user (I am not sure if I am doing this correctly):
Name = test
TYPE = oracledb
username = (blank)
password = (blank)
datebase = prod
When enduser hits the form link, it returns ORA-01017.... same errors.
Any ideas how to trouble shoot and configure RAD for users with OPS$ auth?
thank you in advance!
Kan

Thank you for your input!
This is how our current production is setup that users use os authent (OPS$) to access forms/reports 6i. I'm just trying to migrate it to app10g environment.
I did configure SSO with WNA, it works fine. Any users can access NON-DB connected forms/reports. Only when forms/reports require DB conn, users who
have db password can access them with one click. But users identified externally will keep seeing Oracle Logon and Ora-01017 after authent into MidTier.
Setup RAI with one real db user account is not ideal since there are 1000+ OS authent users who have different database roles. Turn off the OPS$ and setup dummy password for 1000+ users may be the last solution.

DATABASE_LINK with CURRENT_USER for user identified externally

Hi,
My database is in standard edition 10.2.0.5 on windows.
I have a user OPS$xxx identified externally.
the connection with this user "sqlplus /@service_name" is ok.
A database link has been created with these options :
select * from dba_db_links;
OWNER DB_LINK USERNAME HOST CREATED
OPS$xxx TEST_DB CURRENT_USER SERVICE_NAME 19/10/11
This database link references the same database
( it is an external application which has created it).
if we test with sqlplus, we have :
sqlplus /@service_nameSQL*Plus: Release 10.2.0.5.0 Production on Fri. Oct. 21 09:58:40 201
Copyright (c) 1982, 2010, Oracle. All rights reserved.
Connected to :
SQLPLUS> select count(*) from user_tables@TEST_DB;
ORA-1017: invalid username/password; logon denied
So is it possible to use this type of database link ? And if it is, how can you do that ?
Or only "user identified globally " can use database links with current_user...
Thank you in advance for your help.
Best regards
Marie

A connected user link should work per the reference:
The ability to use a connected user database link depends on several factors, chief among them whether the
user is authenticated by the database using a password, or externally authenticated by the operating system or
a network authentication service. If the user is externally authenticated, then the ability to use a connected user link
also depends on whether the remote database accepts remote authentication of users, which is set by the
REMOTE_OS_AUTHENT initialization parameter.HTH -- Mark D Powell --

Schema owner identified externally

I have an oracle 11g, apex 3, OHS implement. The schema assigned to my workspace has owner, identified externally. I can find no workspace/schema relation administering Oracle-XE. Looks like the database username that logs in to the Administration Home is the schema to be parsed. My trouble is that I cannot login to the Administration Home with the user identified externally.
Please advise.

I've upgraded the version of Apex that was installed with Oracle-XE. I matched Apex version with that of the Oracle 11g environment; that is, version 3.1.2. So, now I can create developers and workspaces that reference schemas of the developers' choosing, than the one developer (database user) owning the schema it references.

hi
my OS is windows 2000 professional addition
Oracle server version is 9.0.1
i created an operating system user "guest"
then set OS_AUTHENT_PREFIX=""
then i restarted the satabase
then i created a user as follows
"CREATE USER GUEST IDENTIFIED EXTERNALLY
QUOTA 10M ON UESRS"
then i assigned him previleges
now i logged on to system as "guest"
and run sqlplus as follows
sqlplus /
and it returned me error "ORA-01004"
kindly tell me did i follow the right steps???
if yes then why isnt it working
Regards

Possible Causes and Remedies:
Operating system authentication has not been enabled for the system.
Check {ORACLE_HOME} \ NET80 \ ADMIN \ SQLNET.ORA on both client and server. To enable operating system authentication it should contain the line:
SQLNET.AUTHENTICATION_SERVICES = (NTS)
If the registry key HKEY_LOCAL_MACHINE \ SOFTWARE \ ORACLE \ OSAUTH_ENFORCE_STRICT is set (true) then verify that the user is a member of one of the following NT groups: ORA_<SID>USER, ORA<SID>DBA, ORA<SID>OPER, ORAUSER, ORA_DBA or ORA_OPER.
If the Oracle database is in a different domain from the logon domain then a trust relationship must be set-up between the two domains for operating system authentication to work.
The system does not support operating system authentication. The error may in this case be accompanied by the error ORA-01988: remote os login is not allowed. Log on supplying password and username.

How do I get PowerBook G4 with Tiger to identify external Numeric Keypad?

I just bought a Travel Solutions Portable Numeric Keypad Model 60-320, which says on the packaging System Requirements: Windows 98, 2000, Me,XP or Mac OS.
The Installation instructions say:
Connect the USB cable of the Numeric Keypad to the USB port on your computer. Your computer will automatically read the keypad. You are now ready to use.
I have Mac OS X 10.4.7
When I plug the Keypad in the Keyboard Setup Assistant opens, with Introduction: Your keyboard cannot be identified and will not be usable until it is identified. To identify this keyboard click Continue.
On clicking Continue, one is required to press the key immediately to the right of the Shift key on the left side of the external keyboard.
It apparently did not occur to whoever wrote this Setup Assistant that people are more likely to want to plug in numeric keypads rather than full keyboards, and that numeric keypads do not have Shift keys!
How do I get the computer to identify the Keypad?
PowerBook G4 Mac OS X (10.4.7) 15"

Welcome to the Discussions!
I cannot answer your question, but maybe you can return the keypad you bought and get the Kensington keypad/calculator <http://www.amazon.com/gp/product/B00009L1XO/102-7465461-6085726?v=glance&n=172 282>, which works fine with my PB G4.

Questions Re: Partitioning External Hard Drive

I need to free up some space on my MacBook Pro, but first I need to reorganize my external hard drive. It's presently divided into five partitions, as follows:
Mac - Mac OS (Extended Journaled) - 100 GB
Mac 2 - Mac OS (Extended Journaled) - 115.76 GB
Media - Mac OS Extended - 100 GB
Websites - Mac OS Extended - 50 GB
PC - MS-DOS (FAT) - 100 GB
I use the first two for cloning my hard drive, the next two for storing images, videos and websites, and the last one is reserved for files I copied from the PC I abandoned when I bought my Mac.
In fact, the last partition (PC) has about 80 GB available, so I'd like to take 75 GB and redistribute it. I'd like to wind up with something like this:
Mac - 100
Mac 2 - 145
Media - 150
Websites - 50
PC - 25
In other words, I want to add more capacity to the partitions Mac 2 and Media.
First question: Is there a way to shrink PC from 100 GB to 25 GB without erasing the data it contains, then expand Mac 2 and Media without destroying the data they contain?
If not, there's another possible solution. My last attempt to clone my hard drive failed, so I erased Mac 2; it's empty.
So could I reformat it as MS-DOS, resize it to 25 GB, then copy all my files from PC to Mac 2, then either reformat and enlarge PC or delete it and create a new partition?
When I open Disk Utilties and click on my external hard drive, I can then click on each partition and see its stats. But I don't see any way to resize any particular partition. At the top of the panel it says Volume Scheme, below which it lists Current, followed by other partition schemes (3, 4, 5, etc.). However, I assume that clicking any of these would erase all my data.
So can anyone suggest a way to reorganize my external hard drive without losing all my data?
Thanks.

All the commands remain grayed out when I click on various partitions. Maybe it's because I'm actually booted up on my external hard drive. I deleted several GB of files from my internal hard drive, but it still won't boot up. So it looks like I have a technical problem, and I'll have to visit my local Apple store. After I get it fixed, I'll take another look at re-partitioning my external hard drive.
Thanks.

Scratch Disc Questions using Firewire External Drive & Imac

Hello. I've read through the existing questions regarding scratch disc and Photoshop, yet can't seem to find an answer to my questions. I would greatly appreciate any tips/advice. Here is my setup and situation:
I am running an iMac with a 2.16 intel core 2 duo processor, 3 GB memory, and running OS X version 10.6.4. I am currently using versions cs3 and cs4 of Photoshop, but plan to upgrade to cs5 soon.
The problem I am having is when running Photoshop, my computer becomes very slow. After reading about possible reasons, I came across a couple of sources (including Adobe themeselves) mentioning that the scratch disc should be a designated drive seperate from the drive containing the operating system. Since I am using an iMac that only allows for one internal drive, my only apparent option seems to be an external drive.
Many people say don't use an external drive, but if you are going to; use an eSATA or firewire. The imac does have firewire 800 capabilities. Should I consider this?
Now I'm wondering if it's a bad idea to purchase a macbook for my next computer (what I wanted to do) because it will also only have one drive, not allowing for a seperate drive for the scratch disc. Any thoughts? I've read around the net but haven't found any definitive answers.

Designer,
Photoshop benefits greatly from having a scratch disk on a separate physical drive, not on the boot disk or on another partition of the boot disk. It's almost not worth connecting via Firewire 400 because the transfer limitations don't allow much performance improvement. But using a Firewire 800 connection gives excellent performance.
Running Photoshop on a one-drive machine is a little frustrating due to the performance hit without the separate scratch drive.

Questions about iomega external hard drive.

Hi guys, I own an iomega 1TB external hard drive. Till now I've been happy with it despite its fan tends to be noisy, but I'm facing a lack of space issue. Elgato's EyeTV pretty much took up most of it. Rather than buying a second hard drive I was thinking on replacing its internal disks. I opened it up and saw two 500GB with a connector I had never seen before. My question here is, if I bought two 1TB disks with the same connectors, could I just swap them? Would they work? Said new disks actually would come from a Sun's storage rack. Are disks compatible? I mean, would I be able to re-format it/them to be used with Leopard easily (like using the Disk Utility)? Would the iomega box recognize them and be able to handle them?
Once all above's sorted, I'll just have to worry about the data migration, which isn't any simpler at all. I know no-one who owns any storage solution that I could borrow to temporarily store all the data. And if go to anyone they might not have Mac-formatted disks.
Sorry if you think this post shouldn't be here. iomega won't help at all and I believe this Mac brotherhood can enlighten me through this odyssey.
If you need more info from both current and new disks I can email you pictures of the labels of both. Email me directly at [email protected]
Thanks in advance.

Moving to Mac from PC: Question about using external HD

I am trying to figure out how I will move my files from my PC to my new iMac when I get it. This would include favorites/bookmarks, music, document files, pictures, etc. I was looking for clarification regarding the use of an external HD as I have gotten different answers elsewhere.
Can you use the following process?
1. Connect an external HD to my PC and copy my files to the external HD. I assume I would need to format the HD on the PC and that it woudld be FAT32.
Note: My PC has USB 1.0 and a firewire card.
2. Connect the external HD to the iMac and copy my files from the HD to the iMAC. Can the iMac recognize a drive as FAT32?
Related questions:
I have not purchased an external HD yet. If the above is possible, anything I need to consider in the type of external HD I purchase?
After I move the files to the iMAC should I reformat the drive on the iMAC since it uses a different format?
Thanks for the help.

Connect an external HD to my PC and copy my files to the external HD. I assume I would need to format the HD on the PC and that it woudld be FAT32
If the drive is 32GB or more, you cannot normally format it to FAT32 on a Windows XP or Vista machine. If this happens, use the Disk Utility in the /Applications/Utilities/ folder on the Mac to format it as MS-DOS, or choose NTFS on the PC.
Connect the external HD to the iMac and copy my files from the HD to the iMAC. Can the iMac recognize a drive as FAT32?
Yes.
After I move the files to the iMAC should I reformat the drive on the iMAC since it uses a different format?
If you only want to use the drive on a Mac or formatted it as NTFS as noted above, yes.

Contract Generation question: Formatting, Numbering of clauses, variables

Hi!
I am trying to create a Contract Document Template (for Contract Generation) with Variables
I created some Variable Collections, but when I link them to the Contract Template, they add on with a different formatting altogether, which is neither like the placeholder in the template nor like the template attached to the variable.
My variable configuration was of the type Paragraph.
If anyone has any helpful tips on formatting Contract Document Templates, it would be most appreciated.
Also, how do I ensure that numbering of sections and clauses is sequentially made in the final Contract.
Regards,
Reshma

I was able to fix the problem by making some word document format changes.
Please ignore this question.

First mac, questions on managing external drives

Have been using iphones, ipods, apple tv's, ipads for a long time. Finally got my first mac (macbook air). Hoping some people can help with a few questions on external drives, I have two nas drives on my network:
- In finder each drive shows up with its official name, is there any way to give it an alias type name (in windows I would map it to a letter).
- On the NAS there is a 'share' folder with all of my content. I added this to my devices section for easy access, but again, is there a way to give this an alias? Both NAS's have 'share' folders and I can't tell the difference between them. I see an option to create an 'alias' for folders within share, but can I create an alias name that apps can recognize for the 'share' itself?
- I added the 'share' to my login list for my account to mount it on startup, is that the best way to do it? I checked the box to hide it but the finder still pops up with it on startup.
- General question on finder. When I download and install software it usually shows up on the desktop and in finder with an 'eject' button next to it. Aren't these just folders with files in them or are they something different that causes them to have an eject button? Just trying to understand how things work behind the scenes and it is confusing to see downloaded software behave like an external device that you would eject.
Thanks in advance for any help you can provide. Really like the mac in general, but just need to adjust to all the new concepts.
Thanks,
Peter

i may have an alternative:
if you are comfortable with AppleScript, you could edit this script to suit your situation:
try
mount volume "afp://<AirPort Extreme Name>.local/<Share Volume Name>"as user name "<Share Username>" with password "<Share password>"
end try
this script just places the drive's icon on the desktop. save it as an application and add that to your login items.
credit for the script goes to Tesserax.

those are .dmg's (disk images).
