I'm try to connect to databases with DBLINK. It works, but I drop the dblink to do it again in the final server. The problem that I now is that there is not any DBLINK in my database but I can see the data of the other database (with select 1 from DATABASE.TABLE)
Is my database saving the data of the other database without de DBLINK?
My program needs to connect to two databases and make operations in both databases:
Quote:connect to db1;
connect to db2;
select from table in db1;
update table in db2;
i would like to know whether it's possible, and how to do it ? how to specify for each query the database connection to use?
note that I can't use dblinks as i don't have enough access rights and privileges on neither of the databases.
I have created a procedure which i am executing in one database, in between the procedure i need to connect to diffrent database, how can i do it..
example procedure:
I Started executing procedure in DATABASE1 and i want to switch to DATABASE2
CREATE OR REPLACE PROCEDURE TEST_CONN IS
BEGIN
--SQL STMTS
CONNECT USERNAME/PASSWORD@DATABASE2
--SQL STMTS
END;
/
In my application i need connect different databases from a form. How can i do that?

I just created a dblink from our Oracle 9i database to a SQL Server 2008 R2 Server using oracle heterogeneous services. The dblink seems to be OK and I can query the remote SQL Server database but I only get results for numeric columns.
Say the remote SQL Server table was created like:
CREATE TABLE [MITLOC] (
[MLCONO] [numeric](3, 0) NOT NULL,
[MLWHLO] [nchar](3) NOT NULL,
[MLITNO] [nchar](15) NOT NULL,
[MLWHSL] [nchar](10) NOT NULL,
[MLBANO] [nvarchar](20) NOT NULL,
[MLCAMU] [nvarchar](20) NOT NULL,
[MLFACI] [nchar](3) NOT NULL,
[MLWHLT] [nchar](2) NOT NULL,
[MLSTQT] [numeric](15, 6) NOT NULL)
The remote dblink is named after M3PREP.
Then if I run:
CODEselect MLCONO, MLSTQT from MITLOC@M3PREP => this works OK and I get the two columns.
If I run:
CODEselect * from MITLOC@M3PREP => I get the same results as in the previous query and all nchar, nvarchar type columns are missing, I only get the same two columns.
If I run:
CODEselect MLCONO, MLWHLO from MITLOC@M3PREP=> I get ORA-00904 - the column name entered is either missing or invalid.
I set up my .ora init file like this, I suspect there is something missing here, is it related to the NLS_LANG or so?
CODE#
# HS init parameters
#
HS_FDS_CONNECT_INFO = M3PREP
HS_FDS_TRACE_LEVEL = 4
HS_FDS_TRACE_FILE_NAME = M3PREP.LOG
#
# Environment variables required for the non-Oracle system
#
#set <envvar>=<value>
We are accessing data from the server ADM.WORLD by using DBLINK.We got the following error.
PL/SQL: ORA-04052: error occurred when looking up remote object
sysadm.PS_HP_INC_ELIG_VW@ADM.WORLD
ORA-00604: error occurred at recursive SQL level 1
ORA-28000: the account is locked
ORA-02063: preceding line from ADM
For that we checked in the server ADM.WORLD for the account the account is showing locked .After that we successfully accessed the object sysadm.PS_HP_INC_ELIG_VW@ADM.WORLD.
For next day also the account is locked.Why the account is frequently locking.

View 2 Replies View RelatedI have a requirement to move the databases to a new server.
Existing set up:
database1-40GB,
database2-40GB,
database3-180GB
Oracle version - 11.2.0.2
OS - UNIX AIX-5.3
New Server (setup):
database1-40GB,
database2-40GB,
database3-180GB
Oracle version - 11.2.0.3
OS - UNIX AIX-6.1
My query is what is the best way to move the database to new server(UNIX AIX 6.1)?
a) can i upgrade the database to 11.2.0.3 before moving to new server or its better to move the database in 11.2.0.2 and then upgrade there?
b)is export and import of database can work for moving this?
c) RMAN backup and restoration can be done for moving databases?
d)simply moving all the related files to new server and start upgrading it from there?
I have Oracle 11g installed on AIX and I want to install another 11gR2 single instance in a different oracle home, will it be possible?
View 3 Replies View RelatedUsing suppress triggers options in golden gate. I was trying to work on the same but it doesn't seem to work at least for me.
Scenario:
Database Version 11.2.0.2
GoldenGate v11
OS Windows
Created two databases on the same server with same schmea idea was to replicate change from one database to other. One of the tables in the source database had trigger(every insertion in the table would cause a row to be inserted into a diff table). if row was inserted in table A it will insert a new row in table B . the same records will pass on target but the trigger defined on table A should not trigger on target as it has already fired on Source .
I tried using suppresstriggers but it doesnt seem to work everytime the trigger is getting fired on target database.
CODEReplicat process
replicat repname
assumetargetdefs
userid gguser@bbb password Oracle
dboptions suppresstriggers
map x.* ,target x.* (since same schema)
The extract files,pump files and replication are working fine.I also used the dbms_goldengate_auth.grant_admin_privilege for gguser.
Also I noticed when I give the dboptions suppresstriggers replication process doesnt startup with unrecognised word message when i give dboptions suppress triggers the replicat process does start is this the way it should be.i have gone through the docs and it should be supresstriggers.

My boss has assigned me a task to check/audit a existing PROD + other databases which was configured (in a server or servers) by previous dba who have left with no documentation.I am just given the server ip and root password.
-How do you attack this kind of task?
-How do you know how many databases were installed in a given server/machine?
-How do you get all the oracle_home being defined or used?
Is /etc/oratab enough to start with?Is oraInventory enough to know all the databases installed? Is this keyword unique, and kind be search using "find / -name "oraInventory"?Do I need to find the existent of the "oracle" exec in all "bin" since this is the unique identifier of an OracleHome?

View 16 Replies View RelatedI'm trying to connect a oracle client application on the client machine to a remote oracle server on the server machine but i get a connection fail.
On the server machine I configured oracle server in the following way:
Installed oracle server. Created a database "DB_Test" with the database configuration assistant Created a LISTNER with the Oracle NET Manager with the following parameter:
Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521 Created "dbtest" service with the Oracle NET Manager with with the following parameter:
Service Name: "dbtest" Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521
All services on the server machine are running and I opened port number (1521) in the router. On the client machine I installed SQL PLUS and SQL Developer.
With SQL Plus as by the official documentation I have entered the following command:
CONNECT username/password@[//]host[:port][/service_name]. In my case is:
CONNECT SYSTEM/oracledb@//ENZOVAIO:1521/testdb.
With SQL Developer I have entered the same parameter.
But with both SQLPlus and SQL Developer the connection fails.
we have oracle server. we have to connect 500+ client machine to oracle server.
is it i need to install client version to all 500+ or any other shortcut way?
