I am using oracle 9i version and in EMCA satndalone application . I have created database links.
The database links have been created, and three databases are local.
When i am pressing the test button in emca . It gives notification database link not active.
What should i do?
A procedure in a package uses a database link. The database link is defined without a username and a password. The user that uses the database link is supposed to be present in the opposite database as wel.
When the procedure is started in SQL*Plus or TOAD it runs perfect. But the procedure has to run in a scheduled job. And that doesn't work. The procedure fails because of: ORA-01017 invalid username/password. The user that is used to run the scheduled job is the right one.
I have installed oracle database 11gr2 in laptop1 and installed oracle database 11gr2 in laptop2.Both the laptop's are connected to same internet connection through wifi.

I have a staging which connects to RAC clusters via dblink..I have a scenario to collect the hostname,systimestamp whenever i do a query from this rac clusters
So in general below would be cool
select UTL_INADDR.GET_HOST_NAME,sysdate,x,y,z from gv$symmetric would work perfect
But on dblink..
select UTL_INADDR.GET_HOST_NAME,sysdate,x,y,z from gv$symmetric@dblink.is returning local timestamp and hostname which is not intended
So i even tried subquery..
select (select host_name,systimestamp from v$instance),t UTL_INADDR.GET_HOST_NAME,sysdate,x,y,z from gv$symmetric@dblink
this would work in certain case ...But it certain cases it would throw an error saying mutiple rows from asubquery .All ineed is to get hostname,systimestamp append to all sql i fetch from any this rac clusters through this dblinks.

I am trying to create a database link using this syntax:
CREATE PUBLIC DATABASE LINK remote
USING 'remote';
where 'remote' is the service name. It creates it successfully giving the message "External database Created"
Note: I am doing using TOAD

select * from scott.employee@remote
it gives an error:

But the 'remote' db entry exists in the tnsnames.
1. we have to use shared server mode with Xa transactions, if not we get this error:
QUOTE ORA-24777: use of non-migratable database link not allowed
Cause: The transaction, which needs to be migratable between sessions, tried to access a remote database from a non-multi threaded server process
2. The SGA and PGA_AGGREGATE targets are limitted to 4GB as an Oracle consultant's recommendation [I don't know the reason, but I have been informed that it is recommended so I don't dare to increase it]
Taking into consideration the above points and the below information, what should I do then... I'm not willling to change the workarea size policy to manual as I'm affraid of the consequences...
QUOTE MTS becomes downright dangerous when Automatic Shared Memory Management (ASMM) or Automatic Memory Management (AMM) is in place.
When you use MTS and AMM (or ASMM) together, PL/SQL programs that try to create large collections can effectively consume all available server memory with disastrous consequences . .
AMM allocates virtually all memory on the system to the large pool in order to accommodate the PL/SQL memory request. First it consumes the buffer cache, then it reduces the PGA_AGGREGATE_TARGET - all the way to zero!"
My problem is I have 3 tables (TEST_TBL1, TEST_TBL2, TEST_TBL3). TEST_TBL2 and TEST_TBL3 are in remote database and I use database link to join them. The following query returns incorrect result (I seems that it ignore the where clause)
SELECT * FROM TEST_TBL1 JOIN TEST_TBL2@db_remote USING (KEY1) JOIN TEST_TBL3@db_remote USING (KEY2) WHERE KEY1=XXX OR KEY2=YYY;

I have one PLSQL package that does a join of two tables of remote database instance via the datalink. I just wonder where the most calculation(the join) is done, local machine or remote machine? Is there any best practice to have a better performance for such configuration.
View 3 Replies View Relatedon my Windows 7 machine with Oracle Client 12.0.1.0 installed I'm trying to create a database link to a database server, that runs under Oracle Standard Edition1 11.2.0.2. When i login to sqlplus on the client with "sqlplus /nolog" and type the command : SQL> create database link SID connect to user identified by passwd using 'tnsnames.ora connection'; I'm getting an SP2-0640: not logged in.
Ok, thats clear, because i use sqlplus with /nolog option. But on client side normally I have no database, where I can login. So I think, there will be no user, or? The database to which I want to connect is set in tnsnames.ora. Generally: Is it possible to use the Oracle Client to create a database link?
I have 2 databases:
Database A
Database B
In Database A I have a series of config tables and stored procedures/functions In Database B I have a lot of tables.
I would like to execute my stored procedures and all associated functions in database A on my data in database B.
Now I've figured out that creating a database link enables me to do SQL selects on data in both A and B...but how do I run SP/Funcs ? I've read something about packages but not sure if I'm heading in the right direction.
Do I need to create a simple synonym ? Can I use the existing DB link ? or is there a special way of calling them, or...
I like the A/B database set up since I can keep battle tested code in one location and have it work across multiple dbs...saves me having to create everything in every database.
