Distributed Transaction In MTS Using Shared Dblink Fails With Ora-00022 [ID 280247.1]
 

Symptoms

When using shared dblinks to do a distributed transaction from
MTS to MTS the client might see errors of the form

ORA-02050: transaction 840.21.16 rolled back, some remote DBs may be in-doubt
ORA-02068: following severe error from ...
ORA-00022: invalid session ID; access denied

Cause

Shared servers closed down there by closing the dblink

Solution

Set shared_servers = max_shared_servers in the remote instance
 
既然是使用shared database link 那我們就查詢下是否有這樣的dblink
SQL> select NAME from sys.link$ where AUTHUSR is not null;
 
NAME
--------------------------------------------------------------------------------
BUSISYS.REGRESS.RDBMS.DEV.US.ORACLE.COM
確實存在，我們只需要drop 掉然後建立非shared database link。
