DBlink Data

Hello,
I am having problem in selecting data from dblink.
here is the query
SELECT PRODUCT_CNT FROM SPF_L4_PRODUCT@LinkedDB s WHERE s.REVISION = (SELECT TO_CHAR(SYSDATE-2,'DD-MON-YYYY') FROM DUAL);
this query is returning no records, but if i execute the same query in the linkeddb it gives me output.
even when i run * SELECT PRODUCT_CNT FROM SPF_L4_PRODUCT@LinkedDB * it gives me all records without problem.
but when i use the where clause i get no records.
I am not able to understand what is the problem.
Any help will be highly appreciated.
Thanks
Deepak

OK. Then your query is wrong.
If you have a DATE column, you should always compare it to a DATE value. If you compare a DATE to a VARCHAR2, Oracle has to implicitly cast the date to a string which will use the current session's NLS_DATE_FORMAT as the format mask. Different systems have different NLS_DATE_FORMAT values, different sessions within the same system can have different date formats, and different client machines can have different date formats. Relying on implicit conversion will invariably cause problems where things work on one machine but not another or for one user and not another.
You should get the results you're looking for with the query
SELECT PRODUCT_CNT FROM SPF_L4_PRODUCT@LinkedDB s WHERE trunc(s.REVISION) = trunc(SYSDATE-2)If REVISION is always stored with a time component of midnight, you can eliminate the TRUC on REVISION. If you need the TRUNC, you may want to create a function-based index on TRUNC(s.REVISION) for performance (assuming there are many different values for REVISION).

Dblink data copy

Hi,
I have 3 instances (instance1, instance2, instance3). DB links exists between instance1 and instance2, instance1 and instance3.
instance1 <-> instance2
instance1 <-> instance3
I want to copy data (some records from a table) from instance2 to instance 3.
What is the best and optimal way to do this data copy. Can I use some stored procedure in instance1?
Please suggest.

I am assuming when you say instance1, instance2 & instance3 they are different database instances. I would like to call it db1 db2 & db3
If you are referring to multiple instances of same DB (RAC) then all the data is accessible across all instances.
A simplest way
- if the number of records are not very high
- provided table structures are the same across db2 & db3 and
- you have privileges to write into db3 from db1.
insert into table@instance3 as select from table@instance2

DBLINK confusion

Hi,
I am getting an error on Insert flow into I$ table step while execution.
I am connecting two database from two different hosts, both are in oracle.
I have two logical schema prepared for both database.
should i have to mentioned these schema in one physical topology? what should be placed in schema and work schema option.
I have used LKM Oracle to Oracle(DBLINK) as KM.
Please help
Best regards,
manish

Hi Manish,
Are you accessing target DB machine remotely, if yes you need to create DBLink at target DB machine and you need to specify same at Topology Manager>Oracle technology>Physical Architecture> In Definition tab Instance / dblink (Data Server)
I hope you are not provided DBLink details at Instance / dblink (Data Server) while configuring target DB in topology manager
I think you got error " *Caused By: java.sql.SQLSyntaxErrorException: ORA-01729: database link name expected* " when you using LKM Oracle to Oracle(DBLINK) as KM

Insert via DB-LINK

Hi, i'm trying to insert via dblink data selected from local table. Here is the code:
create or replace type T_DATA_IDS as table of number(19);
export_process_ids t_data_ids;And here is the query:
    insert into process@archive
      (select * from process where process_id in
        (select * from table(export_process_ids)));And it throws
ORA-22804: remote operations not permitted on object tables or user-defined type columns
When i change '(select * from table(export_process_ids))' to some id's from that table data is inserted without errors.
How can i work around that error?

ODI11g Integration Step: Insert flow into I$ Table failure: TNS: error

The project/interfaces have been working successfully for quite sometime. After a server reboot, they are all failing on the Integration step
Insert flow into I$ Table failure with:
ODI-1228: Task xxxxx(Integration) fails on the target ORACLE connection xxxxxx.
Caused By: java.sql.SQLException: ORA-12154: TNS:could not resolve the connect identifier specified
I have verified the topology and the dblink/Data Server is what resides in the tnsnames.ora file (which also has not changed).
Any ideas what else to look at, all topology connection tests are successful.
Thank you.

All connections were testing successfull. The problem ended up being with one of the database links, after the server reboot there were multiple tnsnames and the environment was not pointing to the correct one. After removing all tnsnames except for the correct, the problem was fixed.
Thank you for your response.

Performence Imporve

1.I am inserting bulk load 9 GB file into oracle database but performence is not upto the mark.Its taking arround 99 minutes which is very high.There is index on one field of target table.I am using LKM file to oracle(external table) and ikm sql control append.My target+staging area are on same location.
Oracle 11g ,ODI and file is located on same machine.
2.Then i simultaneous launched two parallel odi integration interface.Means i inserted 2 9 GB file into oracle database(accord. to Simultaneous Launching Of Multiple Parallel ODI Integration Interfaces
My target+staging area are on same location
Oracle 11g ,ODI and file is located on same machine..and it took 4 hrs.
How to improve these performences?

I am not able to insert using sqlloader bcz getting error at File.err

How to transfer DATA from one machine to another using DBlink

I want to transfer data from one machine to another both having oracle 8.0.5 with AIX operating system using DB link. CAn any one help me in this task

Step one - Create and test SQLNet connections between the databases.
Step two - Create at least on database like from one database to the other:
CREATE DATABASE LINK linkname
CONNECT TO user identified by password

I am getting ORA-02063 error while copying bulk data from DBLINK

Hi all ,
I am trying to copy data from DBlink ,whenever i am trying to pull more data ,The db link break down ,
I have try to put /*+ APPEND */ (Hint) in insert statement.Below is the insert code from my procedure
from where i am getting below error
"Error in copy_data_pkg-3113 ORA-03113: end-of-file on communication channel

Insert code:
INSERT /*+ APPEND */ INTO target_tab

and UPPER(action_var) not like '%SC_NET%' and UPPER(action) not like '%ROAM_NET%' and UPPER(action) not like '%PUP_NET%';
COMMIT ;
Please suggest me ,why i am getting this error.

Can you elaborate the thing... I don't think /*+ APPEND */ this is working for me ,still I am getting same error.
If you have any other suggestion,I would like to hear.
Should i not put commit after some 500 records inserted ? As i am putting commit once after whole data gets inserted.

Copying table data accross a dblink using dbms_datapump

Hi Friends,
I need to copy a table data accross a dblink into another table of same structure.
There is a requirement to use 10g dbms_datapump package to copy the data.
The problem is that I can export into a dump file and then import it into the other database, But we do not need the dump file. We need directly exportimg and simultaneously importing into the table through dblink without generating the intermediate dump file.
If any one have a sample code or document link, Please do help.
cheers

But the application we have that uses the database cannot be changed to read from a CLOBWhy can't you change the application?
Well, anyway you should point out to your superiors that Oracle documented years ago to not use LONGS anymore...
http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/datatype.htm#sthref3806
It clearly states:
LONG Datatype
Note:
Do not create tables with LONG columns. Use LOB columns (CLOB, NCLOB) instead. LONG columns are supported only for backward compatibility.
Oracle also recommends that you convert existing LONG columns to LOB columns. LOB columns are subject to far fewer restrictions than LONG columns. Further, LOB functionality is enhanced in every release, whereas LONG functionality has been static for several releases.
How do I go from CLOB to LONG?I'm sorry, cannot help you on that one, I don't think you can do that at all (Oracle wants us to stop using LONGS, so, it's a one-way conversion...):
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:1037232794454#15512131314505
So: NO built_in, you'll need to write a program if the clob is ALWAYS LESS THAN 32k in size, you can use plsql..but is that the case in your case? Only you know that.
I believe that question is still unanswered on this forum, but you might try searchin for answers on this forum, and
the 'Database-General' forum: General Database Discussions
Perhaps you can google a Q&D workaround...
( And consider convincing your collegues to just convert your LONGS to LOBS)

PowerPlant passive Oracle dblink to read data from SAP ECC?

Hello
We have a third party vendor named PowerPlant that is proposing to integrate with SAP ECC using a passive dblink to pull data into PowerPlant. This is proposed when SAP ECC is running on an Oracle database. Presumably this is a read-only connection to the SAP ECC Oracle database (at database level). Has anyone used this and/or have recommnedations for or against?
Thank you,
Harold

Hi Harold,
Technically it is possible but, check your Oracle license with the local SAP office. As far as I know that SAP is not permitted 3rd party connections to the database.

Using DBLINK in ABAP to retreive data from externam system

Hi All,
Please help me, if anyone knows the answer.
The basis team has created a dblink 'DBL_TEST.YY.XXX.COM'.
Now I have to fetch data from another non-sap external system using this dblink only. Cannot have any entry in DBCON.
I know the procedure of retreiving data using DBCON entry. But since DBCON will not be used here, so I have to use the DBLINK to get data from an external oracle table (say, ZTEST).
I need the procedure to implement the logic in abap program.
Thanks in advance,
Ipsita

My problem is now solved. We created views @the database level, and fetched data using the database view in Native SQL.

Accessing DB2 data through DBLINK in Java program recieves ORA-02063 error

Hello,
Is it posible to access a mainframe DB2 table through a Java JDBC connection utilizing a DBLink / Synonym. Using Toad or SQLDeveloper, I can select the DB2 data just fine. Also, PL/SQL programs can access the data without issues. When I try to select data from the DB2 Table in a Java program, I get ORA-01002: fetch out of sequence -- ORA-02063 preceding line from DB2D errors.
The code I am using to test is:
(Note: TBL_LOC_ADR is the Synonym that points to the Mainfram DB2 table)
public static void main(String[] args) {
          Connection con = null;
          Statement stmt = null;
          String query = "SELECT * FROM tbl_loc_adr";
          ResultSet rs;
          try {
               System.out.println("Getting connection");
               con = BatchDBConnection.getDBConnection();
               TestConnection tc = new TestConnection();
               System.out.println("Creating ps");
               stmt = con.createStatement();
               System.out.println("Calling qds");
               rs = stmt.executeQuery(query);
               System.out.println(" Returned data " );
          } catch (Exception e) {
               System.out.println("Error " + e.getMessage());
               e.printStackTrace();
The error occurs on the rs = stmt.executeQuery(query); line.
Thanks for any input into this error. It's been driving me nuts all day.

Hi ,
we managed to reproduce the case in test environment, below are the steps:
1)have 2 databases on different machines, will call the first one local, the other one remote.
2)in the local database create:
a - DBLink to remote database.
b - read data from remote database(we simply used select count(*) from dummy_table )
c - insert data into a table on the local database
d - terminate the connection between the 2 databases (disconnect either machine from the network)
e - commit on local database.
what we noticed was the following:
1)when the local database is disconnected from the network(the machine is not connected to any network at the moment): almost immediately throws an error, and issuing the following:
select * from dba_2pc_pending;we found some data .
2) when the remote database was disconnected(the local database is still connected to the network):
after 7-8 seconds an error is thrown, and issuing the following:
select * from dba_2pc_pending;did not return any data.
since this is pretty similar to our case ,we concluded that it's a network issue.
is this the correct behavior ?
as a temporary solution till the network issue is fixed ,we did the following:
1) changed the call of the remote procedure to calling a local procedure that calls the remote procedure.
2) added pragma autonomous_transaction to the local procedure.
3) at the end of the local procedure rollback the autonomous transaction.
it seems that since the global transaction does not use the DBLink database does not issue a 2PC commit.
this works in my cases since the DBLink is only issed to read data.

Data transfer using dblink

I am transfering the data from Mysql database to Oracle 11gR2. I using a control table( here temp_tab ) to maintain the details of the source and target table and dblink info.
Also p1 is the procedure used for data transfer. My problem is
1) I am not able to move data for some of the MSQL tables as they have text columns. The text columns cannot be queried and inserted in oracle database. tables The whole insert
fails. The work around can be to use column names in select through which i am inserting data ( i can give null as <columnname> ) so that i can get text field as null for now.
But the problem is if i hard code the values in select dynamic character of code is destroyed.
2) I wanna use bulk collect in my code so that if one records fails the whole data of table doesnot fail. So that save exception can be used for record failure.
Can anyone suggest a work aroung in this code.
temp_tab
================================
source_tab     target_tab          dblink
aaa@dblink     aaa1               dblink name
bbb@dblink     bbb1               dblink name
ccc@dblink     ccc1               dblink name
procedure p1 is
     cursor cursor_tab is select * from temp_tab;
begin
     for cur in cursor_tab
     loop
          begin
               EXECUTE IMMEDIATE 'insert into ' || cur.target_tab || ' select * from ' || cur.source_tab;
          exception
               when other then
                    dbms_output.put_line(' the error is :: ' || sqlerrm(sqlcode));
          end;
     end loop;
end p1;

What in your code is dynamic and requires native dynamic SQL?
Cursor FOR Loops have been obsolete in the Oracle database for more than 12 years ... why are you using one and why are you using a loop at all?
It appears that all you have, and require, is INSERT INTO ... SELECT * FROM.
You source table definition does not reference or use a database link. Why?
