Database link logs..

Hello,
I am not able to find the connection logs for the error in database link..
For eg i have two databases DB1 and DB2, i have created a database link in DB2 which connects to DB1.. Database link is working fine but sometimes i am getting "ORA-03113 - End of File On Communication Channel"
I am using the database link in one trigger..
I am not able to find this error in alert_log.. do anybody have any idea where can i find this error..?? in DB1 database or DB2 database and where would it be under bdump, udump or network log..???
Any help would be great
Thanks - HP

Well but since this is an ORA error i believe it should be displayed somewhere in some log file even if it is from database link..
And some times we do get ORA-03113 error displayed in alert.log then why not in this case..What you are looking at is a hardware/OS/network level error captured at RDBMS level and presented to you in the form of an error.
This error message is generally accompanied by other messages.
Probably having an ON SERVERERROR trigger and capturing the entire error stack might prove helpful.

Create private database link

Hi,
I am currently working on a 92080 database on HPUX RISC platform.
I have a question regarding DB link.
There is already a public database link. I want to make it private since our organaization doesnt allow public database link.

Or can we create a private database link logging in as SYS/SYSTEM. Please let me know
Thanks!

You can create database link in one schema and after that you can create public synonym ,therefore all users can use this db link.
CREATE DATABASE LINK DBN
   CONNECT TO SMART IDENTIFIED BY sm
   USING 'SB222'
/You can create objects like view according this dblink and create publik synonym for this

HELP! FOR LOOP TO SCROLL THROUGH TABLE AND CREATE DATABASE LINK

Hi,
Here's the scenario, not much of a PL programmer, just basic SQL so really need some help people!
I have 2 tables. 1 contains list of DB's and the other contains rules to follow.
I need to create a loop that goes through the table containing the DB's and on each row a DB link is created (Only 1 link allowed!)
Once created, the schema currently logged in with also has an account on the linked DB in order to run scripts- The scripts are stored centrally hence the requirement for the link to the target DB.
There are numerous scripts that need to be executed and can all be called from 1 script, once executed the loop exists and the database link needs to be dropped.
Once dropped, the first loop continues, creating a DB link for the next DB listed in the table (and all the scripts are fired again)
This continues against all the DB's listed in the table.

Hi BlueShadow,
Thanks again for the response, you've hit the nail on the head. SQL scripts on a unix server, a loop goes through a table 1 at a time. Each row gets a link created and then all the scripts stored on the server are executed against the db linked to. So I'm assuming this is a loop within a loop.
1 loop to go through the table to create the link and then another loop within once connected to execute all the scripts against the connected DB. Once the scripts are run, the loop exits and moves onto the next server and so on until all the servers have the scripts are run.
It's PL/SQL scripts we're after and not shell scripts as this would free us from the OS constraints.
We have to drop the links due to security. Any idea on o

How to Create Public database link in oracle 9i?

Friends,
OS: RHEL AS 3
DB: 9iR2
database name 1 = nubul
database name 2 = test
in the 'nubul' database server using system user.
i created a database link to connect the 'test' database
sql> create public database link test using 'test';
database link created.
then i logged in as normal user....
sql> select count(*) from employee@test
Error at line 1:

where i am making mistake?
i gave the linkname as my remote database name.
am i have to make any entry in the tnsnames.ora?
thanks & regards

You have to remember that when you access a dblink, the database where the link is defined is acting as a client to the database to which the link points ... exactly the same as if you you were using sqlplus on the machine hosting the db where the link is defined. In other words, given:
Host 'Host-src', with database 'db-src', with a dblink 'lk_target'
Host 'host-trgt', with database 'db-trgt'
When you connect to db-src and access lk-target, db-src is now acting as a client to db-trgt. Exactly as if you had opened sqlplus on host-src and connected directly to db-trgt. So, given the above scenario
host-src$> sqlplus scott/tiger@db-src
sql> select * from emp@lk_target;when you execute that SELECT to the link, the same tns considerations are in effect as if you had
host-src$> sqlplus scott/tiger@db-trgtThe same tnsnames.ora entry, on the source machine, is required for both.

Database link from Oracle to MySQL

I tried and googled an tried again...but I can't get this to work. So if you can spare a moment, please help me out (or try to ;-) ).

libc.so.6 => /lib/libc.so.6 (0x005b1000)

So it can find and load the necessary libraries (afaik)..
So any ideas left??

ORA -18808;Cannot find OUTLN schema using Database Link

Hi,
I have to access a database using a database link. When I try to do so I get the message:
ORA -18808:cannot find OUTLN schema
The OUTLN schema really does'nt exist at the target database, but I don't get the message when connecting with the same user outside the database link.
I am trying to avoid to ask them to recreate the schema, since I am the only one that needs the database link working.
Is there any way I can access the database with the database link without messing with the target database?
Thanks in advance for any help.

The error number returned by that error does not seem to be correct. Below is the correct error number:
ORA-18008 cannot find OUTLN schema
Cause: The database creation script that creates this schema must not have been executed.
Action: Review the log files to see what happened when the database was created.
How is the DB link defined to connect as?

Using database link via dbms_scheduler

Hello out there,
I have a problem calling a stored procedure via dbms_scheduler that pulls some rows over a public database link.
The setup is the following:
create public database link mediabase using 'mediabase';
create or replace procedure hole_kurse as
mdatum date;
begin
   select max(datum) into mdatum
   from dt_wechselkurs;
   insert into dt_wechselkurs l
      (waehrung,
       datum,
       wechselkurs)
   (select
       r.waehrung,
       r.datum,
       r.wechselkurs
    from
       dt_wechselkurs@mediabase r
    where
       datum>mdatum);
    commit;
end hole_kurse;
begin
   dbms_scheduler.create_job(job_name          => 'wechselkurse',
                             job_type          => 'STORED_PROCEDURE',
                             job_action        => 'hole_kurse',
                             start_date        => sysdate,
                             repeat_interval   => 'FREQ=DAILY; BYHOUR=7; BYMINUTE=0; BYSECOND=0');
   dbms_scheduler.enable(name => 'wechselkurse');
   commit;
end;
/I can access the database link in SQL and I can call the procedure hole_kurse from SQL without any errors. But the job fails writing "ORA-01017: invalid username/password; logon denied" into alert.log. I also tried using dbms_job which used to work with Oracle 10g but now fails with the same error.
My Oracle version is 11.2.0.2 64bit on Window Server 2008R2.
So what do I have to change that my job will run?
Many thanks in advance,
dhalek

I'm not completely sure, but here is a possibility:
The [url http://docs.oracle.com/cd/E11882_01/server.112/e26088/statements_5005.htm#i2061505]docs have this to say:
>
If you specify CONNECT TO user IDENTIFIED BY password, then the database link connects with the specified user and password.
If you specify CONNECT TO CURRENT_USER, then the database link connects with the user in effect based on the scope in which the link is used.
If you omit both of those clauses, then the database link connects to the remote database as the locally connected user.
>
Your dblink is like this:
create public database link mediabase using 'mediabase';That is the third case described, so the link connects as "the locally connected user", which in the scheduler session is probably not your user.
You may try it with the second case described in the docs:
create public database link mediabase CONNECT TO CURRENT_USER using 'mediabase';If I understand the docs correct, then within the procedure the dblink will use the schema that the procedure is owned by (unless the procedure is using invoker-rights, then it will be the invoking user.)
It is just a guess, but you can try it and see ;-)

Error while creating materialized view which using database link

Helo!
I'm getting error "ORA-00942: table or view does not exist" when I want to create materialized view.
Details:
1. On destination database I create a database link:
CREATE DATABASE LINK SDATABASE
CONNECT TO MYUSER
IDENTIFIED BY MYUSERPASS
USING 'ORCL';
=> Command "SELECT * FROM TABLE1@SDATABASE" returns data normally!
2. On source database I create MATERIALIZED VIEW LOG:
CREATE MATERIALIZED VIEW LOG
ON TABLE1
WITH PRIMARY KEY
INCLUDING NEW VALUES;
3. Now, when I want to create MATERIALIZED VIEW on destination database:
CREATE MATERIALIZED VIEW TABLE1
REFRESH FAST
START WITH SYSDATE
NEXT SYSDATE + 1/1440
WITH PRIMARY KEY
AS SELECT * FROM TABLE1@SDATABASE;
...I get error "ORA-00942: table or view does not exist"!
How is that possible if command "SELECT * FROM TABLE1@SDATABASE" returns data normally?
Thanks,
Voranc

And, I'm using Oracle 10g.

Change of a database link in OWB

I have a good suggestion to change a a database link when a server is moved to another location (in that case the database link of the source module has to be changed)
In OWB 9.0.2 it's not impossible to delete a database link in OWB, so you have to do it manually
(in 9.0.4 it should be possible, but this version is also not easy to use).
- Start SQL Plus and log in as the schema on which the OWB repository is created (e.g. OWB).
- Drop the database link ('drop database link <dblink name>')
- Create a new database link in the same schema with the new parameters, e.g:
CREATE DATABASE LINK "<dblink name>"
CONNECT TO "<...>" IDENTIFIED BY "<...>"
USING '(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (Host = <hostname>) (PORT = 1521))) (CONNECT_DATA = (SID = <sid> )))'
Done!
No stupid errors in OWB when you create the database link in OWB itself.
Regards,
Maurice

Database link with current_user

I'm logged on database EMSDB.D710.DE and created a database link to EMSDB.D999.DE with current_user(...same user, same credentials I'm logged in). When I tried to use that created link I get the errorcode:"ORA-01017: Benutzername/Kennwort ungültig; Anmeldung abgelehnt". What I don't understand is, why I can connect to EMSDB.D999.DE --- but not access to the same database with a database link???

Thank you, John...but should it be possible for me to create this database link then???
As I said, if you are not a global user according to Oracle, you would need to create a database link supplying the username and password of the user at the remote database that you want to use. Something like:
CREATE DATABASE LINK EMSDB.D999.DE
CONNECT TO username IDENTIFIED BY password
USING 'EMSDB.D999.DE';
How to spy out, what kind of user (GLOBAL...) I am?Log into the local database and do:
SELECT external_name
FROM user_uses;If that return null, then you are not a global user, if it returns a value, you are a global user in that database. Log into the remote database (whatever is identified by emsdb.d999.de) and do the same thing. If the external names on both databases are not null and have the same value, then you are a global user on both databases, and the current_user should work, otherwise you are ethe not a global user on one or both databases, or you are a different global user on the two databases.

Database link failure.

Using the grouper account, I have a database link defined as follows:
CREATE PUBLIC DATABASE LINK parent_link
CONNECT TO parent IDENTIFIED BY "password"
USING 'rem1';
... and several synonyms, one of which is defined as follows:
CREATE PUBLIC SYNONYM valid_fishery FOR parent.valid_fishery@parent_link;
I am able to log in as parent in SQL Plus and Select from valid_fishery.
But when logged in as grouper, I could not Select from valid_fishery, using either method of access:
Referenceing the table name: Select * from parent.valid_fishery@parent_link;
Referenceing the synonym: Select * from valid_fishery;
I get the message:
ORA-01017: invalid username/password; logon denied.
ORA-02063: preceding line from PARENT_LINK
This message is obviously wrong because I logged in through SQL Plus with the exact same username/password.
Clearly, something is wrong with the link, but what could it be?
Edited by: Prohan on Sep 23, 2009 9:33 AM

Proham,
I have seen various issues when going downward across database links (from a higher version of database, to a lower version of database). This has been probablematic over the years in various versions and with different commands that are typically fixed.
Sometimes, in the past, I have seen incorrect errors raised over db_link issues. I believe I even recall selecting from 'dual' returned an error, or when running certain commands using a procedure or package on the remote database.
First thing I'd ask to check (even though it does not seem related), is to ensure either grouper, (or public) have select access to 'parent's' tables.
Does grouper have an account in the remote database? This shouldn't matter actually since you created the link to connect to through parent.

I have a problem when update tables with a database link (APEX)

Hi, I search answers for my problem and I not found a solution. My problem start when I open page with database link statement in APEX. I drop tables and execute this for update the tables in APEX.
EXECUTE IMMEDIATE 'CREATE TABLE XXXXXXX
AS
SELECT A1,A2,A3
FROM AAA@BBB';
I use Mozilla Firefox and isn't always updated the tables because it shows dialog for downloading file "f". I rename the file to txt and I see the text "IBMPC/WIN_NT-8.1.0"...
In the explorer always show a window only the text "IBMPC/WIN_NT-8.1.0"...
What is the solution for my problem? I need update this tables.
Thanks. John.

It's easy. It doesn't work a database link, on apex, with a pl/sql code or store procedure.
I saw that many people had the same problem but I don't see a solution.
As I put up, I want to remove my tables on APEX and copy the table of my Oracle database with the update dates.
The posts are from the same problem as my English is very bad, it got to help explain the problem.
I have a page with a pl/sql code. This code in Oracle is correctly.
For example, with this code I update the table PRUEBAS with the data of TABLEX.
BEGIN
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE "PRUEBAS"';
EXCEPTION WHEN OTHERS THEN NULL;
END;
EXECUTE IMMEDIATE 'CREATE TABLE "PRUEBAS"
AS
SELECT AAA,
BBB,
CCC
FROM TABLEX';
END;
But, in this code, I have the problem.
BEGIN
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE "PRUEBAS"';
EXCEPTION WHEN OTHERS THEN NULL;
END;
EXECUTE IMMEDIATE 'CREATE TABLE "PRUEBAS"
AS
SELECT AAA,
BBB,
CCC
FROM TABLEX@DB_LINK';
END;
I sometimes get an error. Sometimes it works fine, but half of the tries Apex returns "IBMPC/WIN_NT-8.1.0" in the browser and I am not using an IBM PC or Win NT...
And i read that In the alert_xe.log file there are a error of core dump... ... :S or that the application return corrupt headers.... Is a problem of versions?
I used a synonym and I have the same problem.
Even if I run the code on SQL COMMANDS (SQL WORKSHOP) it shows dialog for downloading file "f". I rename the file to txt and I see the text "IBMPC/WIN_NT-8.1.0"...
The problem is in Mozilla Firefox and in IE.
I have the OracleXE 10g (Application Express 3.0.1.00.08).
And the question is.. ... ... ... ... What is the solution? :)
Thanks.
John.

Best practice for default location of mailbox database(s) / logs

Hello,
I don't recall seeing any options during the Exchange 2013 install, to specify an alternate location for either the mailbox database or log files. I've reviewed the commands for moving the mailbox databases, but before reviewing the options for setting a
location for the log files, I thought it best to see whether it's still advised to separate log/mailbox databases away from the OS, with our Exchange server being a virtualised instance?
Also, I'm assuming that Exchange still requires the usual backup of transaction logs, for them to be cleared?
Many thanks.

Hi JH,
here is a link to storage options and requirements for the Mailbox server :
http://technet.microsoft.com/en-us/library/ee832792(v=exchg.150).aspx
By default when installing New Exchange server With mailbox role,it will create default database and log path.
Recomended is to have Database and Log files on seperate disks.You will have to attache those disk first,then you can create New database using ECP.
Please look at my Gallery With full guide on how to setup New Exchange server.
http://gallery.technet.microsoft.com/Install-Exchange-server-b5cce9e4
Also for future use you might need to clean up log files to free up Space on Your Exchange server:
http://gallery.technet.microsoft.com/Task-Scheduler-to-cleanup-25047622
Hope this helps
