creating views in a new scheme to access some rows of the tables in the source schema
Hello
Oracle 10.2.0.4
We try to hide some data from some users. My suggestion is that we create a new view_schema scheme on the same instance where we said the source tables in source_schema.
We then create views in view_schema as below
CREATE VIEW AS SELECT * FROM source_schema.table where COLUMN_n = "XYZ";
We then grant SELECT on these views to a role and assign this role new users to be able to consult the data consulted.
If the questions below.
- We can create views to view the data in another schema WITHOUT giving SELECT permissions on source_schema.tanle directluy?
- It works and there is no need to create synonyms etc.
- YOU can manage users and much easilier view (s)
Is there a sense and who better than the selection seen with say table_name_view in the source schema to this effect and even the creation of synonyms for these points of view with the same name, yasmina in sourece_schema?
Thank you

1. you can create the view in another schema (first granting of privileges to the schema of the view) without granting privileges of the schema of the source
2. you probably want to create public synonyms for the view (s). You can refer to the view as schema.view, but it's bulky
3. I'm not sure management is easy, but the extra complexity shouldn't be too bad. Write the documentation describing how everything works and the object involved.
Another, more complicated, but more powerful option is to use row-level security also known as the virtual private database - if you have the license. You create a profile for a table and a procedure to generate the WHERE clause to filter a query against the table and the columns defined in the profile. Yet once, you need license to do this.

Does anyone know a shortcut for create/exit points exactly 1 second (or no preset amount) in the source monitor apart?
For example, I want to choose a second clip sections of 5 minutes, but do not want to move the points of entry/exit with the mouse in the hand. Would also be useful to several clips where 1 s/exit points have not been established
Thanks for all the answers!
Go to preferences and on the set of forward/reverse reading pane, for the number of images you want to move the read head (in this case 60, two seconds):
And click OK.
Then put your first marker, then type shift + right arrow to move the playback cursor, the number of images that you entered.
If you type shift + left arrow , it will move the playback cursor backward the number of images.

Cannot access some sites behind the pix515e
I started my CISCO PIX 515e in July 2004 with a minimum configuration. The only change I made was to introduce the syslog and 3COM tftp server. Two weeks after my Internet (browsers) users (inside) began to have problems of access to certain sites for example google.com, cnn.com etc when I bypass the firewall, they can access all the sites. When I place them behind the firewall again they cannot access the same places. It seems to me that the firewall is the cause. This could be the cause?
Without seeing your config, it is hard to say, but a proposal, I'd say you're probably out of translation addresses. The PIX must create a translation for the traffic as it comes out, and she does that based on nat/global orders, you have in there. Let's say you have the following:
Global 1 200.1.1.1 - 200.1.1.254 (outside)
NAT (inside) 1 0.0.0.0 0.0.0.0
Then, this indicates the PIX to translate any internal address to 200.1.1.x he died. If all of these 254 global addresses be used however the next person who tries to go out will be denied. If you look at your syslog server, you will see a message like "Unable to create translation."
If you change it above to:
Global 1 200.1.1.1 - 200.1.1.253 (outside)
Global 1 200.1.1.254 (outside)
NAT (inside) 1 0.0.0.0 0.0.0.0
then the first 253 users that come out will have their packages would NAT, then all of the other packages will be PAT had to the 200.1.1.254 address, giving you an extra 65, 000 - odd outbound connections.
If that's not enough (remember that only the user going to a few web sites can open connections to 20-30), then you can change the above to the following:
Global 1 200.1.1.1 - 200.1.1.252 (outside)
Global 1 200.1.1.253 (outside)
Global 1 200.1.1.254 (outside)
NAT (inside) 1 0.0.0.0 0.0.0.0
giving you a 65, 000 - odd additional translations and so on.
Other than that, we would need to see your Setup and your messages to syslog (in the debug level) when these users can't get out.

I can't access some website after the recent update of Firefox.
Before the update, I was able to get into my bank account without any difficulty. Now, I question "secure connection failed". The problem is not the firewall because any computer we tried to access the site, including one on another Internet connection, failed. I am able to access the site on other browsers. None of the support or troubleshooting forums helped.
Firefox blocks access to this Web site is because it uses the oldest Monogram RC4. (and the login page is where you want security, if it is little course it will be the first point of attack to access bank accounts).
I suggest that you call the Bank immediately and ask that they use some modern web security.

How to access some files from the Windows.old folder?
I recently made the mistake of updating my OS before save lots of interest - information is all the info from Outlook, I had (e-mails, contacts and calendar).
I have posted a question to the Board of Directors of Windows Vista for the cat, but was recently informed of this discussion here.
THUS,.
I was told I could "...". Browse to C:\Documents and Settings\xp_username\Local Settings\Application Data\Microsoft\Outlook and move the pst file in My Documents folder. It is a hidden file so you will need to activate the hidden files and folders. »
When I tried to do, I got as much as Windows.old > Documents and Settings > xp_username, but when I click on the "Local Settings" folder, I get a message telling me:
"C:\windows.old\Documents and Settings Settings\xp_username\Local is not accessible. Access is denied. »
I get a similar message when I try to enter in the Application Data folder in the xp_username folder.
How can I do at this point? Thank you!

Problem with the new printer print only some word from the quarterdeck documents
I hope someone can help. I have a Dell Vostro and had 8 happy years print on a Canon printer. I just upgraded to a Canon Pixma iP4600 printer. I think that with some (not all) MS word documents it prints the rear tray (mean't for photo paper) by opposition to the tape before (designated for plain paper), for which I set the properties of the printer.
Canon tech support say there is a Windows problem. I already reinstalled the printer driver but sill the same problem. Hope someone can advise.
Happy Days!
BryanHello
This phenomenon only occurs with word documents?
Have you checked if this happens with any other application?
As you have already defined the properties of the printer and the problem is only with a few word documents. The first step would be to check if the word printing settings are defined in law.
To fix printing on word problems, see the steps mentioned in this link:
http://Office.Microsoft.com/en-us/Word/HP051887411033.aspx
Sometimes this also happens if the printer settings are ignored when you print a Word document. To check if these settings are correct, try the steps mentioned in this article: http://support.microsoft.com/kb/904805
If you still find difficulties in printing, run the Microsoft Fix it to reset the settings: http://windows.microsoft.com/en-us/windows-vista/Troubleshoot-printer-problems
Post back with the results, so that we can help you better.
I hope this helps.

How to create views of data from different databases tables in2
Using Oracle 10.2 g
I have 2 databases Gus and the haggis on schema Comqdhb.
Glink indicates a link of database between Haggis and Gus
In Gus, there is school that contains columns with same name upn, grade, subject, student of tables...
STUDENT
UPN
academicYear
Object
Object
GRADE
examlevel
grade
SCHOOL
SN
In HAGGIS raising tables, grade, teacher containing columns upn... desc below.
STUDENT
UPN
GRADE
grade
UPN
academicyear
level
Create views in your database HAGGIS who join their all the qualities of the review. You should have a point of view that will produce the following relationship:
examGrade (upn, subject, examlevel, sn, rank, academicYear)
So I need to create a view that gets the data from the tables in the databases.
create view as examGrade (upn, subject, examlevel, sn, rank, academicYear) like some s.upn
But I don't get the selection of a column of 2 tables in different databases
I mean if I said
Select the UPN in comqdhb.student@glink,comqdhb.student;
Select the upn name in comqdhb.student@glink,comqdhb.student
*
ERROR on line 1:
ORA-00918: column ambiguously defined
Help me, thank you.Hello

The issue is that I can't understand that I should create the view by the union of the haggis and the two gus data or only haggis.
the reason I believe I need to combine the two is mentioned * "" create views in your database schema HAGGIS who join their all the qualities of the review. ". *
By the mention of creating views and who join their all the qualities of the review, it probably means to obtain the data of the GUS and HAGGIS.This is my interpretation of the assignment, too.
If you ask just the tables on Gus, you will get the ranks of three of the four schools: it's not all examination classes.
If you ask just the tables on Haggis, you will get the ranks of any of the four schools: it's not all examination classes.2nd prob is that if have decided to create a view that gets the data from these two gus and therer haggis would be a lot of duplication involved due to the cross product
Why would there be "repetition involved due to the cross-product"?
If the quuery of Gus produces 100 lines, the request of product Haggis 30 rows, then the UNION of the two will have 100 + 30 = 130 lines (assuming, as you say, each student is at school only one).the query I wrote is
Create view examGrade (upn, subject, examlevel, sn, rank, academicYear)
as
Select distinct s.upn as upn, g.subject as topic,
g."LEVEL" as examlevel, g.grade as rank, to_number (g.academicyear) as academicyear

s.UPN, sb.subject, g.elevel, g.grade, s.acyr select Union

b spend this time formatting your code, so I can understand the question, and no time to answer, or
b spend only a little time reading understanding your code and spend most of my time to help you?
I would prefer (b), but the choice is yours.
See the statement that I posted in my last post for an example of the formatted code. You see how it appears in a box with a police fixed-width, and multiple spaces are printed? This is because I typed {code} (all small letters), before and after the section I wanted formatted.At least put each table in the FROM clause on a separate line, so it is easy to know if you have enough join conditions.
If you have N tables in the FROM clause, you almost always have at least N-1 join conditions that specify how the tables are linked together. For example, if talk you about two tables, quality and student, you expect to see a join condition that tells you when you have data in a table, how to find related data in the other table, such asg_gus.upn = s_gus.upn
No no no join conditions will cause "repetition involved due to the cross product.

Make a sample set, containing a few (maybe five) students and a few shades of each student. It is fine to copy a few lines of your actual data.That's all the time I have for today. I can't wait to get the data and formatted requests.

Is it possible to have the source and target schema in the same instance of DB?
Hi all
I'm using Oracle 11 g 1 material.
I spent another source than with OWB server locations.
In the course of deploy I get VLD-3064 and I can't deploy mapping due to the many warnings "table or view does not exist.
Is it possible to have the source and target schemas in the same case?
How to do?
Kind regards
MartinHi Martin!
1. the target schema have select rights for source-tables/views.
(Run as a user with dba rights: grant select onto ;). 2 «.. . none generated code will use the link dataabase...'.
This is only a warning and means there is no need to use a database link. If your mapping will be executed faster as using a database link.Greetings

I can't access some websites from my computer
In recent weeks, I've been unable to access one of my favorite sites. I can also access some features of the iTunes app which worked fine before (in the iTunes Store). I can't access my antivirus tech support either. I called my IPS and there is nothing wrong with that. They were able to access the site, I couldn't, so the site is not offline. I tried the Fixit, but it did not help. My IPS technology had me run a check of the computer and it says that the site was very good but it does not communicate with my computer or my computer does not communicate with him. Why is this happening all of a sudden? I tried everything and nothing works. I can access the site of the library computer and access all the features in the iTtunes store but I don't want to continue to use the computer in the library when I have a perfectly good home. Nothing has changed in my settings will be why my computer thus contacted some sites and not others? I'm seriously frustrated by that. Someone at - it any suggesttions that I have not tried?

How to create an access as guest at the Adobe viewer?
Hello
My client and I want to create a new store and I want
give my client a feedback of tests and drawings.
Can I create an access as guest at the Adobe viewer?
I want my customers to provide the application resulting to discuss jointly
the same development and testing. But do not want the client generally
has access to my Adobe ID code is there a way to do this?
There may be one general alternative am open to everything.
But I would like to remove my clients in order to provide the application resulting
to examine and test.
best regards, Liljana
Message geändert durch Liljana *.
You can ask your client to create an Adobe ID and then you can share your specific work / folio with identifier Adobe in this way you should not share your Adobe ID and password with the customer and the customer must also do not share their password / other details with you. The best part is when you make changes to your folio user shared automatically get this change. The user just has to take the update.

That's the point... So actually you were never more than one domain using the same patterns, you have never shared patterns on different fields... You had a domain which would sometimes... Not possible in 12 c but because of OPSS more... Maybe you could just the OPSS schema duplicated, but you would always use the platform so that it was not intended to...

Privilege to allow a user to create a view of another user schema

I need allow a user create a view of another user schema.
Say, log in as the latter and run the statement: "create view USER_B_SCHEMA.myview as select...". »
Is there a way to achieve this without the agreement of this last privilege to CREATE ANY VIEW? I want to keep it on the profile as low as possible.
Thank you!You can create a stored procedure, here's a test case (not optimized, no free bug):
SYS@orcl > create user sp_owner identified by sp_owner; SYS@orcl > grant create any view to sp_owner; SYS@orcl> create procedure sp_owner.create_view ( 2 view_name varchar2, view_sql varchar2 ) is 3 begin 4 execute immediate 'create view '||view_name||' as '||view_sql; 5 end; 6 / Procedure created.

I found that will help you solve your problem,
the original instructions have been written by Shenan StanleyPosts: n/aRe: Main administrator account appearing notIf you can connect with the new account that you created (which should be an administrator account as well) then go directly to step 2 below.I suppose that you use the administrator account as your main account (bad

somehow enabled the guest account or create a new account - or
installed some patches that created a new account - as .NET.I guess also that (since you say "appear") you also use the 'Welcome' screen
