List of all Oracle Server databases

PEX
I have a few questions.

1. in Sql Server, we can use sp_databases stored procedure to list all the databases on the server. Is there any kind of functionality that will allow me to list all databses to an oracle server.

2 to connect to an oracle server using visual studio is easy if we have tnsnames.ora but if we don't have it, it is a must to use the format of the alias in the Data Source property, while we create the connection string.
Thank you

So if I can't provide data bases, and what I understand of your responses, it should be possible to enumerate all the instances running on the server. In the affirmative, please let me know how do or direct me to the correct c# classes that will allow me to list all instances.
The idea is that I want for all servers in the network from the list, and then select the a specific server. From this specific server, I want to list all running instances. thansks

Implementations are not the same. Pick up the guide of the Concepts of http://tahiti.oracle.com (and use the site to access the Documentation in general).

In Oracle, you have a database (logical), not referenced by name, unlike the MSSS2005 which uses a database.schema.object structure naming. There is a SYS schema, without system databases each with their own schema sys etc. Of course, there are many, many more differences. Welcome to a new world! :)

  • How to get a detailed list of all workbooks in Oracle Discoverer Database

    Hello

    Is it possible to create a query that would give me a list of all workbooks in my Oracle Discoverer database which includes what tables were selected to create the query, including the conditions?

    Please let me know.

    Thank you.

    Hi Becky,

    Discoverer should be bundled with the V5 EUL business district. I don't know which versions have, so I'm hoping its all of them. It allows you to build reports on file in the database, when they were performed last etc. I don't know if you can report on database tables.

    I found a useful documentation about installation and usage of this here http://download-uk.oracle.com/docs/html/B10270_01/eul_stat.htm#1004700

    I hope this helps you.

  • Is there a way to get a list of all applications / updates that are cached on your server?

    Is there a way to get a list of all applications / updates that are cached on your server?  Of course, we see the space that contains each category.  But I would like a detailed list of the individual items that are actually cached.

    ITD be even better if I could get a scoreboard that showed me how many times a particular point was served to customers.

    Yes.  But you need a little magic Terminal to get the desired data.  Caching server is managed by a sqlite database.  To examine the contents, follow these basic steps:

    1: connect to the database using the following command:

    sudo sqlite3 /Library/Server/Caching/Data/AssetInfo.db

    2: to structure the data, run these two commands to the sqlite command-line prompt:

    .blog column

    . Headers on

    3: to find everything that is stored, run this command (you'll get iCloud cached documents, books, iOS apps, etc.):

    Select * from ZASSET;

    4: to narrow the results down to elements called by software updates, try this:

    Select * from ZASSET where ZURI as "content %";

    You could get a line that looks similar to the following:

    403 2 6 0 2012986793 474949928.477396 476912032.644505 e03448847909547fb8c7d4ecd5a7b6dd FAB32A72-DE33-469D-A7DF-3CE1A1F9A4D2 on Wednesday, August 5, 2015 18:00:30 GMT

    / Content/downloads/42/44/031-30888/bhrkylcnycxmtug9daw3g4magqb7dl7hba/OSXUpdComb o10.1

    (added the newline for readability)

    It is an OS X Combo update.  It is located on the drive to library/server/cache/Data/FAB32A72-DE33-469D-A7DF-3CE1A1F9A4D2 / the file is probably named 0, but if you want to use it, just add at the end of the .pkg file.

    I hope this helps.  Put server cache saves a lot of data.

    Oh, to quit the sqlite command line tool, simply type .quit and press return.

    It should work without problem.

    According to the following document, you should have the kernel version 2.6.18 - 8 or higher.

  • a list of all the tables, columns and their consntraints in the database

    Hello

    I need to write sql code which considers a list of all tables in the database, their columns and the primary or foreign key for each column (if any) and the refrence for each foreign key column.

    Any ideas how ro?

    DROP TABLE table_b;
    DROP TABLE table_a;
    --
    CREATE TABLE table_a (
     CONSTRAINT pk_table_a PRIMARY KEY (column_b)
    ,column_a INTEGER

    );
    --
    CREATE TABLE table_b (
     column_c INTEGER
    ,column_d INTEGER CONSTRAINT fk_table_a REFERENCES table_a(column_b)
    );
    --
    
    SELECT  utc.table_name
           ,utc.column_name
           ,CASE WHEN uc.constraint_type = 'P' AND position IS NOT NULL THEN uc.constraint_name END primary_key
           ,CASE WHEN uc.constraint_type = 'R' AND position IS NOT NULL THEN uc.constraint_name END foreign_key
           ,CASE WHEN uc.constraint_type = 'R' AND position IS NOT NULL THEN uc.r_constraint_name END referenced_key
    FROM    user_tab_cols utc
            LEFT JOIN user_constraints uc
              ON  (utc.table_name = uc.table_name)
            LEFT JOIN user_cons_columns ucc
              ON(ucc.table_name = utc.table_name
                   AND utc.column_name = ucc.column_name
                   AND uc.constraint_name = ucc.constraint_name)
    WHERE   utc.table_name IN ('TABLE_A','TABLE_B');
    

    TABLE_NAME COLUMN_NAME PRIMARY_KEY FOREIGN_KEY REFERENCED_KEY

    TABLE_A COLUMN_B PK_TABLE_A

    TABLE_A COLUMN_A

    TABLE_B COLUMN_D FK_TABLE_A PK_TABLE_A

    TABLE_B COLUMN_C

    If you want to 'improve' the referenced_key column for the column referenced actually, you need to join user_cons_colums once again and use the column position.

  • How can I get a list of all links/URLS used in all emails Eloqua?

    I try to have a report, list, or the export of all links/URLS never used in e-mail Eloqua (about 250) assets. Is there a quicker, more precise and perhaps automated to do this other than to pick up manually?

    Basically the desired result is a list of all links/URLS used in an Excel worksheet, additional information is a plus.

    If there are ways through the API, it is also welcomed.

    The Web site is subject to a few changes and we would like to keep all links living in them the remapping to the end server.

    Hi all

    First two ideas come to mind:

    1. go to Insight and run the Email clicks link ventilation report to see the links and clicks used in various emails. This will allow you to search for links to the last 730 days. However, note that if you have an abundance of links, the report may timeout. This is why the guests page, you may need to search specifically for a range of dates (month or two at a time) until you have all the expected results.

    2. using other APIs. The live docs for Rest API include the ability to search hyperlinks in emails. For instructions to access the direct documentation, see the Oracle Support Document 2078514.1 (how access rest and bulk API Live Docs) to: https://support.oracle.com/epmos/faces/DocumentDisplay?id=2078514.1. Once inside the live docs do the following:

    • Click on liabilities
    • Click/assets/hyperlinks
    • Expand the Hypertext GET/assets/links
    • Entry 'Complete' in depth to make sure that you check out the URL for each hyperlink

    Let me know if it helps!

  • Character set US7ASCII AL32UTF8 migration to Oracle Applications database

    (2) CSALTER

    (3) DMU

    Nordine salvation,

    I suggest you to refer the link: "How do I convert the character set for Oracle R12.1.1 running on 11.0.6 database Oracle US7ASCII' as it is very relevant to you."

    Response to your previous post would be:

    S ' stick to a plan

    -Try all of the activity on the TEST server for yourself

    -Troubleshoot and debug all the question from A - Z

    -On the successful implementation, make a backup of the Production and move the solution to PROD.

    If possible, run a lot of questions while doing the character set migration oracle applications, database because it contains the application tables.

    I accept the fact that EBS database is complicated to a database independent, but still all the features and debugging tools and troubleshooting is the same, although it is autonomous or EBS database.

    We should do if we stuck to the top in with and truncate in the application according to the CSSCAN results tables,.

    little tables when we checked in Metalink he says to avoid these tables which do not affect the database or application.

    Try in a Test Server, the above link helps you on the issue. You can find answer to some tables with loss in metalink if it's a bug, just lift a SRt solve your problem.

    What we must do if we are in important application tables, export and import will help in this issue.

    No, if we have available data with loss, then we cannot use the Import/Export and we will have to use CSALTER instead.

    is this the right method or must contact oracle support for assistance on important application tables.

    YES, I personally recommend you try and paralleling have ongoing Oracle support. So that you will have a guide from A to Z, in the case you're wrong

    Hope this helps

    What you ask is impossible. Oracle Forms is designed to interact specifically with the Oracle database. You can access the other tables in the database in an Oracle using Oracle heterogeneous Services database, but right ODBC is no longer supported.

  • List of fixes OracleAS 10.1.2 group

    Hi all

    Is there a way I can find a list of all patchsets of Oracle Application Server 10.1.2? I know that the most recent is 10.1.2.3 but do not know if a newer version has been released.

    In addition, must ask all patchsets any I use functions or not? And where can I find the characteristics of each patch?

    Thank you.

    Rayyen

    It has only three sets of patch still went out to the family of OAS 10 g. The last is 10.1.2.3.

    PatchSets introduce no new features. Releases the latest full version of the software adds new features. PatchSets is a cumulative set of the patch fixes bugs found in a press release.

    It is generally recommended to use the latest round of patch.
    -One of the benefits are that you get most of the bugs bugs.
    -Another advantage comes in modernization. Generally, most of the tests for the process and upgrade scripts for OAS held since the last level of Group of patches for newer versions. For example, to move to FMW11g of OAS 10 g, more in-depth tests would be to upgrade OAS 10.1.2.3.

    That's why in all the new SRS, Support Oracle strongly suggests move you to the latest version of patch game.

    For the latest patches and patch sets for OAS 10 g R2, see the following article on MOS/Metalink.
    [Oracle Application Server 10 g Release 2 (10.1.2) support \[ID 329361.1\ State and alerts]
