Cannot query tables in remote database

Hi, I have looked around for similar topics but have not found anything that would be close to my problem. I created a public link to a remote database from my portal database, it is a public link and I can query tables in the remote database just fine when I am on the sqlplus prompt. When I try to create a report, or a dynamic page, it lets me go through the wizard steps ok, however when I run it as a portlet or just run it as a report/page it does not seem to be able to see the query. Below is the response I get from running it as a portal. I am logged in as portal30.
ORA-01017: invalid username/password; logon denied
ORA-02063: preceding line from C2K (WWV-11230)
Failed to parse as PORTAL30_PUBLIC - select * from populate@c2k (WWV-08300)
The preference path does not exist:
ORACLE.WEBVIEW.PARAMETERS.1320061995 (WWC-51000)
The preference path does not exist:
ORACLE.WEBVIEW.PARAMETERS.1320061995 (WWC-51000)
Error: Unable to execute query (WWV-10201)
Please help, I have tried everything from public to private synonyms for the linked tables and it just does not work. I am using the most recent version of portal that came with ias 1.0.2.2.0

Actually I solved my problem, it looks like I should have used the db link utility with the portal, I linked the databases on the sqlplus command line and it seems like that was the issue.

Selecting from Materialized Query Tables (DB2 UDB database)

When selecting what objects I wish to view in my Reports, I am unable to see any Materialized Query Tables in the list. I am able to see the "normal" Tables and Views, just not any Materilized Query Tables.
Please let me know what I need to set or customize in-order to see and then select fields from these.

Thanks everyone.
I was able to find the answer.
For the new report, in the "Create New Connections"...choose "OLE DB (ADO)" --> then "Microsoft OLE DB Providers for ODBC Drivers" --> click on the "Next" button --> choose the database --> then user/password details (..and so forth).

Best way to create table at remote database side

Hi ..
I have one table around 60GB and i want to sync this table with remote side database table.
Options
1> Creat DB link and then fetch data.
Problem <<Performace issue and May be chance of Network chock >>
2> Using DBMS_REDFINITION package.
Problem <<Again we need 60GB Extra sapce to create New table and Related indexes >>
Can any one suggest me by any other way we can sync table at remote side with source with out adding space and no down time?
Thanks

Still a duplicate thread. Still needs to be moved to the correct forum.

Querying Tables from seperate Databases

I'm sure this is very simple, but I cannot figure out how to query information from two tables that live in two seperate databases.
Ex.
Select database1.table1.field1, database1.table1.field2, database2.table1.field1
from database1 left outer join database2 on database1.table1.field1 = database2.table1.field1
Any help would be appreciated!

If you are using "database" in the Oracle sense, rather than in the sense that other databases use the term (i.e. a SQL Server "database" is analogous to an Oracle schema), you would need a database link.
In database 1
CREATE [PUBLIC] DATABASE LINK dblink_name
CONNECT TO username
IDENTIFIED BY password
USING tns_aliasThen
SELECT tab1.field1, tab2.fieldN
FROM table1 tab1 LEFT OUTER JOIN table2@dblink_name tab2 ON (tab1.field1 = tab2.field1)Justin

Running sql query across multiple (remote) databases

I'd like to run a query that pulls information from multiple databases which are not on the same machine. Is this possible using SQL Developer?

If you are still interested, there is a tool that can query multiple databases and save results in a single text file that you can then modify as necessary - see www.bsutils.com/MuSQL.html

MV Incremental Refresh on join query of remote database tables

Hi,
I am trying to create a MV with incremental refresh option on a join query with 2 tables of remote database.
Created MV logs on 2 tables in the remote database.
DROP MATERIALIZED VIEW LOG ON emp;
CREATE MATERIALIZED VIEW LOG ON emp WITH ROWID;
DROP MATERIALIZED VIEW LOG ON dept;
CREATE MATERIALIZED VIEW LOG ON dept WITH ROWID;
Now, trying to create the MV,
CREATE MATERIALIZED VIEW mv_emp_dept
BUILD IMMEDIATE
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE1/(24*15)+
WITH PRIMARY KEY
AS
SELECT e.ename, e.job, d.dname FROM emp@remote_db e,dept@remote_db d
WHERE e.deptno=d.deptno
AND e.sal>800;
Getting ORA-12052 error.
Can you please help me.
Thanks,
Anjan

Primary Key is on EMPNO for EMP table and DEPTNO for DEPT table.
Actually, I have been asked to do an feasibility test whether incremental refresh can be performed on MV with join query of 2 remote database tables.
I've tried with all combinations of ROWID and PRIMARY KEY, but getting different errors. From different links, I found that it's possible, but cannot create any successful testcase anyway.
It will be very much helpful if you can correct my example or tell me the restrictions in this case.
Thanks,
Anjan

How do you explain the ORA-00942 error first ? Are you able to select that table ? Can we see the merge statement ?

Connecting to remote database without using db links

Referred Thread:
Re: Remote DB connection without DB link
In reference to the thread above, my question goes like this:
Let's say I want to run a query from a database and use data from another database. I have the user, password, SID and port number of the other database but do not want to create a separate connection using sqlplus or connect commands.
Something like this:
SQL> show user
USER is "A"
SQL> select a.col1, b.col2 from tab1 a, tab2@????? where <some condition>;
Can this connection be done on the fly ?? I agree that a DB link will do the trick, but let's say I am not supposed to create objects on the other database.

You need two sets of privs on the remote database to view data in that database schema:
- create session (the schema must allow client connections to create schema sessions)
- select on other schema tables whose contents to view
You need a single priv on the local database, to connect to that remote schema on the other database:
- create database link
You also need the following in order to create the db link:
- the remote schema name and password
- IP address or hostname of the remote db server
- the remote Listener's tcp endpoint port
- the name of the remote database (SID, instance or service name)
If you do not have these privs, you cannot use/access the remote database from the local database session via a database link.
Other alternative methods needs additional privileges and objects on both the remote and local database sides - and are more complex (e.g. using web services, using web-enabled procedures, etc).

Unable to create publication item for remote database using db link

The mobile repository is in instance A.
I have to access and sync data from a table in remote database instance B.
I have run the consolidator_rmt.sql script in instance B under schema_B. I have created a private fixed user db link in instance A under schema_A to access schema_B's tables. I then created a synonym test_B for table test_B in schema_B using the DB link.
While creating publication item for test_B using MDW, the column list for test_B appears blank. Has anyone encountered this problem and what is the solution.
Thanks for your help.

How to find whether remote database is up or not (connected via dblink)

Hi,
I am using dblink to connect Biz database from Dev database.(Biz, Dev - database names)
Running dbms job using the dblink from the Dev database to update data on Biz database...
Problem is dbms job should run if and only if the Biz database is up for which i created the dblink...
1) How to make sure or implement the check to find whether the Biz is database is up or not in Pl/sql or sql...
2) How to reschedule the dbms jobs once the database is up
pls suggest me how to find whether the database is up or not b4 running the dbms job?
Using- Oracle 10g

The only way to know whether the remote database is up (and whether the network between the two databases is up and whether the remote database's listener is up and whether the password configured in the database link is correct and whether the local TNS alias is correct, etc) would be to actually run a query against the remote database over the database link. In other words, the way to figure out whether the link is up is to let the job run and catch & handle exceptions when there are problems.
By default, a job scheduled via DBMS_JOB will automatically reschedule itself if there is an unhandled exception by geometrically backing off (it waits 1 minute after the first failure, 2 minutes after the second, 4, 8, 16, 32 minutes, etc until it's marked as broken after 16 failures). You could, of course, catch appropriate exceptions and handle them in a reasonable fashion and manually reschedule jobs at intervals that make more sense for your particular job.

Query Rewrite to Utilize Materialized Views on a Remote Database

We have our materilized views stored at a remote database. Is there a way to utilize query rewrite to rewrite the queries issued on the local database such that queries will refer the materialized views at a remote db?
From the documentation, I already know that the base tables for MVs and MVs should eside in the same instance or the query should be submitted on the instance where MVs reside if base tables are residing in a different remote DB to benefit from query rewrite.
My aim is to utilize query rewrite to reduce the workload on a primary database by passing queries that can be rewritten to use MVs on a remote DB.
Thanks for the guidance,

My aim is to utilize query rewrite to reduce the workload on a primary database by passing queries that can be rewritten to use MVs on a remote DB. If you know that MVs are not stale or acceptable of staled data and don't see network bandwidth problems (small set of result), You would try accessing MV tables directly on remote db using dblinks.
