Hi
Please help me, I have the next problem creating a trigger for replication in-line.
* The DDL of the trigger is:
CREATE OR REPLACE TRIGGER "MYTRIGGER" AFTER
INSERT
OR UPDATE
OR DELETE ON "USER"."TABLE" FOR EACH ROW BEGIN
IF INSERTING THEN
-- db1: ORACLE.WORLD@DB1 --
INSERT INTO [email protected]@DB1(COL1, COL2)
VALUES(:NEW.COL1, :NEW.COL2);
-- db2: DB2.US.ORACLE.COM --
INSERT INTO [email protected](COL1, COL2)
VALUES(:NEW.COL1, :NEW.COL2);
-- db3: DB3.US.ORACLE.COM --
INSERT INTO [email protected](COL1, COL2)
VALUES(:NEW.COL1, :NEW.COL2);
-- I HAVE 9 DATABASES...
END IF;
END;
* All the DBLinks are tested and active; I can do the insert from sqlplus with the same sentence, in all Dbs. For example, I do this:
INSERT INTO [email protected]@DB1(COL1, COL2)
VALUES(99, 'TESTVALUE');
And It's ok, for all dbs.
* The replicator server is on Novell Netware 5.1, with Oracle 8.1.7 bundled. The target servers (db1, db2, etc...) are distributed between the same Novell 5.1
and Win2003 Server. The target servers are in other cities.
* The database global name of servers that have the error are ORACLE.WORLD... To create the database links, I use this global name with a identifier (dbn...) and this database links are OK...
* In the servers with Win2003, it's ok.. the trigger is created and tested (In this servers are installed Oracle 9i)... In the target servers with Novell (Oracle 8 bundled) I have the next error when create the trigger: (when I include this servers in the trigger):
ORA-04052: error ocurred when looking up remote object [email protected]@DB1
ORA-00604: error ocurred at recursive SQL level 1
ORA-04020: deadlock detected while trying to lock object USR.TABLE
