Export Database Link & Public Synonyms using Expdp

Dear All,
We are using expdp to do schema level exports:
expdp dumpfile=<Directory>:expdp.dmp SCHEMAS=S1,S2,S3
We also want to export the Public/Private Synonyms (created for the objects owned by above users), Public/Private Database Links as part of above command.
How we can achieve this? We are using 11gR2.
regards,
Riaz

HI,
Public synonym can not be exported and never exported even at FULL Export also. . You can get them from "dba_synonyms". I suggest that you create so customer script .
select      'create public synonym ' || table_name || ' for ' || table_owner || '.' || table_name || ';'
from      dba_synonyms
where
     owner='PUBLIC' and table_owner not in ('SYS', 'SYSTEM')
order by
     table_owner;

Public Synonym in Expdp

Oracle:11.2.0
OS: Windows
Is it possible to export public synonym with the help of expdp utility?
If not, what is the reason behind this?
Thanks,
AKPT

No it is not possible. You can run the following scriptm spool it and run it on a desired database
select 'create public synonym ' || synonym_name ||
' for ' || table_owner || '.' || table_name || ';'
from dba_synonyms
where owner = 'PUBLIC'
and table_owner = 'THAT USER'
Also, if you want to export using expdp, you can read the following link

DB Link Public Synonym

Hi Guys
I have a public SYNONYM that was created to access a table on the remote database using a DB Link.
We are able to access the DB Link using SQL Plus and the Synonym BUT when the same is used inside the cursor query of a PL/SQL block we get the following error message!
This is driving me crazy... need your expert suggestion :)

Hi,
As I say, when we access the synonym (that links to a table through a DBLINK) we have this issue. The code can be as simple as
DECLARE
var1 int := 0;
CURSOR S1 IS SELECT col1, col2 from TB_DBLINK;
BEGIN
LOOP through Cursor S1
END;
Here the TB_DBLINK is:
CREATE PUBLIC SYNONYM TB_DBLINK FOR TB_DBLINK@DBL1
The TB_DBLINK on the DBL1 is also a Public Synonym... So it means that a Public Synonym is being created for a Public Synonym!
Able to access this using SQL Plus simple select though :(

Is it possible to export tables from diffrent schema using expdp?

Hi,
We can export tables from different schema using exp. Ex: exp user/pass file=sample.dmp log=sample.log tables=scott.dept,system.sales ...But
Is it possible in expdp?
Thanks in advance ..
Thanks,

Hi,
you have to use "schemas=user1,user2 include=table:"in('table1,table2')" use parfileexpdp scott/tiger@db10g schemas=SCOTT include=TABLE:"IN ('EMP', 'DEPT')" directory=TEST_DIR dumpfile=SCOTT.dmp logfile=expdpSCOTT.log{quote}
I am not able to perform it using parfile also.Using parfile it shows "UDE-00010: multiple job modes requested, schema and tables."

How can you SELECT via Database Link CLOB data using Application Express?

Customer Issue:
Developer using Oracle's Application Express 3.1. The Developer is trying to SELECT a CLOB datatype column from a remote (10.2.0.3) database, via a database link on her 10.2.0.4 based client Application. The Developer wants to be able to select CLOB data from the remote database which has limitation that she can't make any changes to the remote database.
Developer's Comments:
I do a select and get the error. Getting error ORA-22992: cannot use LOB locators selected from remote tables. So she feels she can't use dbms_lob.substr in this configuration I can do a "select into" but that is for one value. I am trying to run a select statement for a report that brings back more than one row. I do not have permission to change anything on the remote database. I want to access the remote database and multiple tables.
This is not something I work with, would greatly appreciate help or ideas. Is this a limitation of the 3.1; or does she just not have this set up correctly; or should she be using a Collection (if yes, please share example)
Thanks very much,
Pam

Hello???
Would really appreciate an answer.
Thanks,

This may not be a perfect solution for you but it worked for my situation.
I wanted to grab some data from Grid Control's MGMT$JOB_STEP_HISTORY table but I couldnt' create an Interactive Report due to the existance of a CLOB column. I cheated this by creating a view on the GC DB, grabbing the first 4000 characters and turning it into a varchar2 column:
create view test_job_step_history as
select job_Name, target_name, status, start_time, end_time, to_char(substr(output,1,4000)) output
from MGMT$JOB_STEP_HISTORY where trunc(end_time) > trunc(sysdate)-90
In an APEX Interactive Report:
select * from test_job_step_history@GCDB
Granted, the output looks aweful right now but I am only looking for a very particular output (failed, denied, ORA-, RMAN-, etc) so the formatting isn't the most important thing to me right now.
If anyone can improve -- and I'm sure you can -- on this I'd love to hear about it.
Thanks,
Rich

Database Link to MSSQL using JDBC

Hi, i'm trying to create a database link from Oracle on Solaris to a MSSQL database. We don't have ODBC installed on the server so i'm hoping to use JDBC to connect. Is that possible? Can someone tell me the format to use for the connection string. Thanks...

It is not possible to create a database link using JDBC.
You could load the SQL Server Type 4 JDBC driver into the Oracle JVM and then write a Java stored procedure that accesses the remote database if you would like. But Heterogeneous Services with Generic Connectivity, which allows you to create database links to non-Oracle databases, only supports ODBC and OLE DB.

Force the use of synonym (database link)

Hello,
I'm on a database DB_1 with the user NP.
In the NP schema I have a table TEST_TABLE.
I create a public synonym on TEST_TABLE referencing a table named TEST_TABLE in a database DB_2 (*the synonym use a dblink*).
In my DB_1 instance connected with NP user, when I run "SELECT * FROM TEST_TABLE", the result is the content of TEST_TABLE in DB_1.
Connected with NP user on DB1_instance, how can i force the use of the synonym to get the content of TEST_TABLE in DB_2 instance ? Is it possible ?
Thanks...

Pl post details of OS and database versions.
I do not believe you can achieve your requirement, unless you name the synonym something other than "TEST_TABLE". The resolution to "TEST_TABLE" will always result in the local table first - the synonym will not be included in the name resolution.

Using database link in my triggers,urgent

There's DB A on ServerA,DB B on ServerB.Table TA in ServerA's DB and TB on ServerB's DB.My purpose is to synchronize usera.TA with userb.TB real time.
In order to realize it,I created dblink AtoB from A to B using command "create database link AtoB.domain connect to userb identified by userb using 'BTNSname';",it's no problem for I have test on it :select count(*) from [email protected];It's ok to get the result.
But when I create trigger on table TA by using the dblink AtoB.domain to update,delete and insert datas to TB,the error "PLS-00201: identifier '[email protected]' must be declared" occurs while compiling.
The oracle version on the two servers is 8.1.7.
It happens on the production envrionment,but in our lab,there's no problem.The difference between them is that it is cluster structure in production one.
I tried several times,but failed,just wondered if some privilege was not right?But I can do selection from this dblink,only in trigger there's compilation errors.
Really hope that someone could give light on it.
Thank you in advance!
In addition,I did some modification in my triggers to have a try.
I created a synonym for the remote table,and the trigger then updates the synonym instead of the remote table [email protected] .But also failed.
The same error,saying the synonym is not declared.
Any good way to realize the same thing?

Thank you for your answering first.
I don't use replication because the destination table's structure is not exactly the same as the source one.
--The selection was done in the production,connection to the source schema,then select through the dblink from the source to the dest schema,the trigger is created in source schema on source table to handle datas in destination schema's table.In lab,all is ok,no such a problem.
--I created two dblinks,one is connect to source as system user,created a public dblink "create public database link AtoB.domain using 'BTNSname';";the other is connect as UserA,"create database link AtoB.domain connect to UserB identified by UserB using 'BTNSname';".

ORA-01017 error while using a database link

Hi all,
I have a TNS entry as below
HOME=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=10.66.205.110)(PORT=1521))
(CONNECT_DATA=(SID=HOME))
I have created a database link as
create public database link link92.com using 'HOME'.
This was created successfully and an entry was made in all_db_links table.
However if i try connecting to a table in the remote database...for example
select * from emp@link92;
I am receiving an error ORA-01017(Invalid username passwd).
Would appreciate if somebody could help me out.
Thank you

It is not that the Database Link is "PUBLIC" that makes it use the current username/password.
It is that the Database Link has been created without specifying a " CONNECT TO username IDENTIFIED BY password " that makes the DBLink behave as a "current user database link" using the current username/password to connect to the remote database.
You can have a PUBLIC database link that uses a "CONNECT TO username IDENTIFIED BY password" such that all connections use the same remote username and password.
You can also have "private" (ie not PUBLIC) database link that does not specify a "CONNECT TO username IDENTIFIED BY password" which becomes a "current user [owner] database link".

as mentioned in oracle documentation for db link purpose: you can use it for accessing schema objects in remote database..
http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_5005.htm
>
Use the CREATE DATABASE LINK statement to create a database link. A database link is a schema object in one database that enables you to access objects on another database. The other database need not be an Oracle Database system. However, to access non-Oracle systems you must use Oracle Heterogeneous Services.
After you have created a database link, you can use it in SQL statements to refer to tables and views on the other database by appending @dblink to the table or view name. You can query a table or view on the other database with the SELECT statement. You can also access remote tables and views using any INSERT, UPDATE, DELETE, or LOCK TABLE statement.
>
For creating users, you have to login to the remote database itself, You also need to login using the user who has the necessary credentials to create the user.

Dipali.

Why is that it is hanging at "exporting system procedural objects and actions"? It already stayed here for 5 hours.You could turn on tracing for the exp session to try to find out what it is doing. If you have AWR/ASH license then e.g. v$active_session_history might be of some use.

Performance for full export database.

Hi,
Is it possibe to estimate or measure how much time needs to export the whole database?
Should I use the parameter "direct=y" to speed up the export process?
Thanks very much.

Hi,
I tried the export in the database server, but the error is encountered.
Is it because the user(system) is different from owner(ds_ap_dwh)?
Anyone can advise me? thanks alot.

6i Report Crashes at Synonym using DBLink

Hello,
I have a 6i Report, (lets call it repx.rdf) consisting of a data model and no layout.
It is used to generate xml.
I have two databases: db1 (with schema jack) and db2 (with schema jill).
To compile this report, my connection is as follows:
jack/jack@db1
In db2 there is a package called:
pkg_fetch_water
In the report, i have a line of code as follows:
pkg_fetch_water.fetch('Y');
To allow this call, i have created a database link and synonym:
create public database link jtoj connect to jill identified by jill using 'db2';
create public synonym pkg_fetch_water for jill.pkg_fetch_water@jtoj;
In sqlplus, the call to pkg_fetch_water.fetch('Y') works fine.
When I try to compile the report from Developer 6i, the entire developer crashes.
I receive no error messages.
Any ideas what is wrong here?

There may be nothing wrong. With you or your work, that is.
However, Reports will crash at the drop of a hat. It is not only unstable, it is not robust, i.e. it can't handle many of the anomolies a program of its age should.
It doesn't get any better with newer versions, either. Well, that's not quite fair. It gets a little better in v10R2 because it, at least, has a crash recovery feature which saves your work in the background and will recover from that point when Reports is restarted.
Auto recovery is a wonderful feature. Now if only Oracle would get off its a$$ and begin addressing the fatal memory flaws in Reports.
