I am having database A and database B and I am inserting into database b by selecting some records from database a using db link.Is there any way to find whether database link is being used?
View 6 RepliesOne of colleague (who has left) created a database link using the statement:
CREATE PUBLIC DATABASE LINK CIVCLMANLINK USING ''CIVCLMAN''
When I try to use this link like:
SELECT * FROM CLIENTMANAGEMENT.ADDRESS@CIVCLMANLINK;
I get the following error:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
I can connect to the CIVCLMAN using the Oracle Enterprise Manager / SQL Plus, I can tnsping as well
I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server.
2. I invoked "sqlplus" from another unix box to login to the database.
3. I found that the process id (ps -ef |grep sqlplus).
4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID,
SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM,
SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID
FROM
SYS.GV_$PROCESS, SYS.GV_$SESSION
WHERE
SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST'
and SYS.GV_$SESSION.MACHINE like '%hostname%'
how will you find your db is Corrupted or crashed. how will u recover it.

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]
To connect the above i made the following changes
$ORACLE_HOME/hs/admin/inithsodbc.ora
---------------------------------------
HS_FDS_CONNECT_INFO = data_extract
HS_FDS_TRACE_LEVEL = 0
$ORACLE_HOME/network/admin/tnsnames.ora

[code]....
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 performed image copy of production Oracle server (OS and instances) to a backup server. After a few weeks, we try to restore a latest Oracle database backup from production server to backup server. As we know, Oracle instance must be unique on the network.
Even we log on to backup server and bring up the instance, I think that still point to production instance since all init file, TNSNAMES.ora and listener file are still same. If we restore the database, we will end up bring down the production instance and restore on top of productions. How to change instance name on backup server including TNSNAMES, sqlnet, listener files in order for us to restore Oracle database from production to backup server?
