How to set up the schema and users?

Hello

I'm looking for the best option for the implementation of the user and the schema in my used Oracle instance only for reports. Version using Ora11g.

Background-

Oracle Ora-Ainstance, is the live OLTP system.

Oracle Ora-B instance will be the new system of reporting , I am building this new system as a reporting instance. My question is how to set up users and safety for installation below?

Planned - approach

Instance Ora - has, some subsets of data is moved to instance Ora-Bnight batch. Using the dblink, I'll be the data.

Required users on Ora-B.

1) ETLUser. -Will extract the data instance Ora-A and load B Orapending.  (User charges/written in the tables only)

2) ReportViewer - read only access on the tables in the instance of Ora-B, for the generation of reports. (User reads only the data in the tables)

You want all report data in a new scheme called 'Report', in the basis of the declaration.

So, how I setup user and schema?

Thank you

Unless you are using versions of the previous decade and material, I do not recommend a separate database.  Material and modern versions run mixed workloads much better that the older systems were, so the need for a statement of the separate databases is dwindling.  The current trend in the industry is to CONSOLIDATE, less material treatment and bodies less.

This has the additional advantage that your refreshes need not go on the network - you get faster performance of refreshment.  They share a buffer cache, so you can get the benefits of data already in memory.  If you are concerned about the damning reports of the treatment, the resource manager may set limits as needed.

Your planned approach to ETLUSER and REPORTVIEWER is solid - good separation of responsibilities.  I would just create these ORA - a, the size of the SGA and CANCEL accordingly and allocate storage, assuming that the hardware supports the need for capacity.

Users and schemas are almost synonymous concepts in Oracle.  They are separated in other platforms to database (such as SQL Server).  In Oracle, when you create a user, you have created a pattern.

  • Transformation to define the schema and user on Tables in relational and physical

    I imported my Designer SDDM 4.0.1.836 deposit.  Now, I want to APP_SYS of subviews allows to define the schema on the tables in the relational model and the user on the physical model.  Our application in designer systems are 90% based scheme.  Here's what I have so far based on the example of OE and HR plans that I imported, built logical, then back to relational.  At this point, I have the tables by subview...  Line 24 is obviously incorrect.  Can someone give me a step by step approach to understand what I need to set the schema of the table and the user?  I looked through the read me file, xml files, the index and searched the known universe and am still confused.

    Hi Marcus,

    First of all, you must make sure that the schema already exists in your relational model.

    You can use the method

    public void setSchema (String schemaName)

    to associate your Table with this scheme.

    (This method is defined on ObjetConteneur, so it can also be used to make and index).

    If you already have a user of your physical model that implements your schema, it is not normally necessary to create a user on the TableProxyOracle in the physical model.

    However if you do not want to set, then the method to use is

    public void setUser (user UserOracle)

  • How to set up the security and Notification

    Hi, I developed a small application for logging calls. I would like to know the procedure of implementation of security and notification settings.

    As I am new in this area, please explain in detail. Screenshots showing the configurations ([email protected]) would be highly appreciated.

    The main features and the application procedures-

    (a) users will see different usernames and passwords to trigger calls on a particular service
    (b) each Department has a call manager that will assign the call to a technician
    (c) the technician will solve the call and update status
    (d) the user will close the call and provide feedback

    Structure-

    1 table to keep users / employees - 1 Page - report and form
    1 table to manage call manager Department wise - 1 Page - report & form
    1 table for calls (stimulus, assign, resolve) - report and our multiple pages (one for the recording, one for the assignment, to solve and feedback with only the corresponding columns of the table) - I have created multiple forms, whereas a call can only be changed by a subsequent user)

    My requirement:

    1. the user must consult only the calls raised by him or her (User1 should not see the calls raised by user2)
    2. the technician should show the call triggered by her (user role) and can also view calls assigned
    3. the call manager can check the calls raised by him (user role) and can also show calls raised on his Department
    4 notification: email should be fired in each event only for the persons concerned, added to the call (the user handler calls, technician)


    Please guide me to implement the features above.

    Kind regards

    About the e-mail notification-, we can create a process under 'Treatment of the Page' for email. In the field 'To' we can provide the string id or replacement of static mail to send mails.

    Not recommended. When generating the e-mail notifications in the way that you need to modify data and sending of the email must be processed in the same transaction to ensure that you don't have change without email or email without modification. Where the suggestion of creating packages of procedures that encapsulate these transactions.

    There are a number of non-obvious events which will cause the APEX to issue a commit which will close a transaction. So, you want all of your transaction in a program unit, called within a single process to the APEX. Packages are the best way to do it.

    How to create the substitution string so that we can get the mail electronic id of the table using SQL? We use several channels alternative if we want to send the same mail to multiple recipients?

    Use apex_mail API with varying normal SQL and PL/SQL in your procedures.

    My BIOS contains an option for the HARD drive password parameter.

    But just a question; Why do you want to set the HARD drive password?
    Is this really necessary?

    You need to know if the HARD drive has been fixed, and that something will go wrong, I mean that if you would forget the HARD drive password, the HARD drive would be locked and is no longer usable.
    So be careful with this password if you want to know my opinion; Don t pay.

    The tuner is already configured!
    You must use Windows Media Center.
    Here, you have to choose the tuner and need to look for available DVB - T channels.

    Notes; Signals DVB - T depends on the country and region.
