Networking And Gateways :: How To Find All The Objects Referring To DB Link
Aug 10, 2012
We have two schemas which earlier used to be separate databases. There were DB links created to access the objects from one schema to the other schema when they were separate databases.
Since now they are just 2 separate schema with in the same Database, we would like to remove the DB Links and create synonyms to access those objects. These DB links were used in code in many places, it is becoming tough to find a way to implement this.
how to find all the objects that are using these objects or all the places these DB likns were being used.
Database version:10.2.0.3 Operating System:Microsoft Windows XP
I have two database TEST and TEST2 on same windows machine. In TEST database i have created one database link that access one schema in other TEST2 database. but when i passed select command to access object in TEST2 through Database link it is hanging indefinitely.
command that i have used to create Database link: create database link scott connect to scott identified by tiger using 'TEST2'
I'm trying to connect Oracle 11g database from Oracle 9i database, by creating dblink on Oracle 9i database. But my session got hang while i perform this. Here i'm giving the steps i followed on my both the database. Here Oracle 9i database is my source db and Oracle 11g is my target db.
Following steps/setting on Oralce 11g Database

DROP DATABASE LINK "SSA11G.SSA_DB1.WBTEA.COM"; CREATE DATABASE LINK "SSA11G.SSA_DB1.WBTEA.COM" CONNECT TO SSA IDENTIFIED BY SSA USING 'DEVDATA.DEV11G';
Attempting to create Database Link which talks to SQL Server 2008R2 system
Database: 11.1.0.7 Oracle Standard Edition Server: Windows Server Enterprise, Service Pack 2 (2008)
I do not have the Oracle Gateway product installed, as this was not configured on my working 10G system.
I tried configuring the link with both the SQL Server ODBC Driver (GMSRES) and the SQL Server Native Client 10.0 (GMSGAS). Returning errors when SQL command is executed.
Everything tests out fine (tnsping, listener configured OK, test connect in Database Link setup). When SQL statement is executed it fails.
Setup:
1. Created ODBC Driver (GMSRES). This tested successfull. Created SQL Native Driver (GMSGAS). This tested successfull.
2. Created initiGMSRES.ora file C:Oracleproduct11.1.0db_1hsadmin folder.
HS_FDS_CONNECT_INFO = GMSGAS HS_FDS_TRACE_LEVEL = OFF HS_LANGUAGE = AMERICAN_AMERICA.WE8ISO8859P15 HS_FDS_CONNECT_INFO = GMSRES HS_FDS_TRACE_LEVEL = OFF HS_LANGUAGE = AMERICAN_AMERICA.WE8ISO8859P15
Connecting Oracle to SQL Server via database link.
I am trying to connect from Oracle 10G to a SQL Server database. I have looked at the manual and i will admit that i am finding the documentation quite difficult to follow. There seems to be several options to use but none of the documentation describe how each option works.
As an example, i have been given the following information on the database i need to connect to (i.e. the SQL Server database)
- Username - Password - Database Name [lets assume the database name is data_extract]
Note: In listener.ora, i only added the last SID_DESC entry. I then went on and created the database link as shown below
create database link sqlservdb using 'sqlserver.db';
When i try to access a table i get the following error
sqlplus> select * from TESTTABLE@sqlservdb; select * from TESTTABLE@sqlservdb * ERROR at line 1: ORA-28545: error diagnosed by Net8 when connecting to an agent Unable to retrieve text of NETWORK/NCR message 65535 ORA-02063: preceding 2 lines from ORASQLSERVER
A couple of things i am not sure of:
- Where do i specify the username and password to access the sql server from the oracle db to the sql server db
- Having read around on the internet, i can see some people refering to a DSN datasource. I am told that the information that i have is all i need. Is this correct or do i need something else?
- The sid i specified in inithsodbc.ora and tnsnames.ora is actually the sql server database. Is this correct?
We got a big problem that we have a db link to connect to sql server(big 5).
In original setting, there is no Chinese characters in the data. We simply grab the data from sql server and do not have any issue. But now we have data with Big5. When we import the data into our Oracle DB, which uses UTF8, all the text becomes "?
Changing character set in DB is not possible. We need to convert the text into unicode format, or allow oracle/sql server to convert it automatically.
i got to find out the users hostname who are connecting to database through remote,i tried with v$session bt it is showing null values in the terminal column.how to find out ?
I have ora-12520. I run Oracle 11g on Red Hat 4 64 bit. Actually I have RAC but one node is down and I work only with up one (connection string point directly to listener of running node). I run test with not too big loading. select count(*) from v$sessions gets ~ 200 in maximum loading, but after half minutes I get this error in my logs. Each time, lsnrctl services show that all is right. It shows one service with one handler. I see nothing in alert.log. This is very strange, I know, and I'm sure that this is an actual alert.log because, I see there other events in actual time. Most important: I have SESSION parameter set to 600 and PROCESSES set to 400 so this must be enougha...
Say i have a Procedure or package or any other stored subprogram, I need a script say to which i can pass this Procedure/Package/View etc name and then the code should give me the data results as which all other stored subprograms are used within the particular stored program name which we mentioned in our WHERE or Predicate clause

I have one production server with oracle 11g R2 DB. I have to change Server Hardware and thats why I have to install oracle 11g R2 DB on New hardware and test it. I had installed DB with software only option and copied the cold backup of production server. The hostname and ip address of both the servers are different. I had change the "db_domain" parameter into init.ora with the hostname.Now my question is that can the same db runs on the same network with different hosts. Change of "db_domain" parameter into the init.ora is enough or i have to follow some other procedure.
Is there a method or a tool out there that can do a search through an Oracle Schema to find objects ( tables, fields, stored procedures, etc) containing a specified character pattern ? For example : I would like to return all of the tables that contain fields containing the character string "ABC"
How can i identify all the occurences of raise_application_error(-20XXX, '<the message>'); within all database objects, and replace them with other text?

I have multiple schemas, all which have tons of objects that point to one column of one table. I tried to look at v$sqltext, and v$sqlarea, but it doesn't seem to show as expected.
Is there a view that I can look at that will show me all the objects that relate to one column?
my situation. Had to change the data structure of this one column. Changed the default value from a Y to an L. I have packages, functions, triggers...etc... that deal with this one column. I need to ensure that I go through EACH one and edit them to reflect the change to the table column. And again, this spans multiple schemas that point back to it.
I installed Oracle Express on my Windows 2003 Enterprise server. And right off the bat I cannot connect to it via command line. I have googled and read many sites, but am still getting the same error, no matter what I do. I am newbie again (was a DBA in 1990...when I used to have the same error and fix it in seconds...not sure why this problem still lingers in Oracle) so most likely I am overlooking something. Below are my tnsnames.ora and liserner.ora files

My client get the error Ora-12514 when he tries to connect to the db.Well;
1) we restart the services: "OracleServiceOrcl" and listener but nothing changes 2) We restart the server and nothing changes 3) We checked the dump and he was done on March,26th. No db export yesterday. Is there any link with the clock change of this week-end (location of the server: France)? 4) The lsnrctl services listener command run successfully but it doesn't mention the instance ORCL.
I have an Access DB which I'm using to connect to an Oracle DB at work. There are several Oracle DB's that I can connect to using Access but this one I'm not able to connect to. I get the Oracle error ORA-25153 Temporary Table Space is empty.
I don't have the ability to make changes to the Oracle DB only to read and query.
When I run the below query, the session got the below errors exactly after 1 hour. I checked profile, resource limit, and sqlnet.expire_time. The SQLNET.EXPIRE_TIME value is 10. Except expire time there is time limit in profile and resource. I dont know how this session is losting connection exactly after 1 hour. What could be the issue here and what else need to check it?
14:34:09 SQL> << DELETE query >> ERROR: ORA-03114: not connected to ORACLE DELETE FROM amsoftinstall
I'd got this error, TNS-12542, address already in used on my multithreaded application.
After finding some documents about this error, it happen because other application used same port as my listener. But i'd assured that only my listener, but it didn't happen in the first running process, but after some processes (hundreds of processes).
