Server Utilities :: Connect To Databases With DBLINK
Jul 17, 2013
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?
I have the task to migrate the total databases(Exact copy to be moved to another server).The current server is going for format.After I did the following steps I am getting the tablespaces(databases)-4 sizes same ,but I am facing issue like some default tablespaces i.e temp,system are not matching.
temp tablespace *************** current server - 4.0(approximately) Migrating server - 160 MB
System tablespace ***************** current server - 580 MB Migrating server - 220 MB
Also I checked the tables are also matching for the 4 databases.Also Provide the solution or method which is correct.
steps done for migrating(By me) ******************************** EXPORTING DATA USING DATAPUMP *********************************
1 From command prompt MKDIR 'c:oraclexeapp mp';
2 From SQL prompt conn system/kotak;
3 create or replace directory dmpdir as 'c:oraclexeapp mp';
4 grant read,write on directory dmpdir to kotak;
5 From command prompt

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?
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.
Oracle 11g on linuxdestination : ms sql server 2005 i need to create the db link from oracle to ms sql server to view the tables , is it posibble without configuring the gateways( as looks like it is licenced product)
We have created a new db link. But we are not able access the remote database. When we are trying to access any table using db link system is getting hanged.
We would like to know what are the parameters/permissions which affect the db link access either at data base level or at server level.
One observation we made is that that particular db link is not getting dropped when we tried to drop it.
while using top command it shows multiple processes usage.Actually we have 3 databases in the same server.how to find out which database process and user session hogging the cpu resources
Using 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?
I have to migrate two different databases to oracle.i have made two Migration Repository for each to do the migration, migration is done.but i would like to know can it be done with one migration repository.if yes then with one is best way to do it.data of two databases is different but table and sp are 99% same.
I am using Oracle database server and I want to show existing databases on that server. Are there any SQL plus command to list all databases there in the server?
I am on Oracle 11.2.0.3 on Linux. In my production database, I am getting this alert, in the alert log:
--the below two lines are from alert log. Error 604 trapped in 2PC on transaction 50.73.546578. Cleaning up.
--query from a data dictionary view SQL> select count(*) from DBA_2PC_PENDING; COUNT(*) ---------- 1
When I query the production database I see that there is one row in the DBA_2PC_PENDING view. But I dont' know how to identify which are the databases that are involved in this distributed transaction. That is my first issue - how to identify which are the two databases that are involved in the distributed transaction?
I want to compare two users on different databases, actaully there are two users one in user a on database a and another user b on database b they have same tables, and everytime when a table or object is created on user a (database a) i will take the table name ,procedure or any other object from user_objects based on ddl_created date and then i need to recreate the same on user b on database b, is there a way to find out tables which are not only created but also i need to check whether if there is any column added or any change in procedure or any other objects.Is there a way to generate the scripts based on list of objects selected from user_objects. all i want is.
a)Find out the list of objects added along with creation scripts b)find out the list of objects modified along with creation scripts.
I'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.
