Oracle Net Services - Version: 10.2.0.1.0 to 11.2.0.3 - Release: 10.2 to 11.2
Information in this document applies to any platform.
Symptoms

- You may be using RMAN for duplication, etc. and receive the following error in the alert log or RMAN screen or log:
ORA-17629: Cannot connect to the remote database server

The full RMAN error may look like this:
Starting backup at 25-JAN-10
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=377 device type=DISK
RMAN-00571: ===========================================================

ORA-17629: Cannot connect to the remote database server
ORA-17629: Cannot connect to the remote database server


- The following would be the matching entry in the alert log:

ORA-17629: Cannot connect to the remote database server


Cause

With 10.2 and higher, the default or incorrect INBOUND_CONNECT_TIMEOUT (ICTO) settings can cause abnormal terminations of programs and tools, such as RMAN, prior to completing the authentication to the remote (target) Database.

This is supported by the engineer notes referencing ORA-12535, ORA-12170, and ORA-3136 errors that can occur with the incorrect ICTO values.
Solution

To ensure the error is not being generated by an incorrect ICTO value, add or edit the following lines in the respective files (do this on both sides, origin and target so the two communications are set the same):

listener.ora -->
INBOUND_CONNECT_TIMEOUT_ = 120

sqlnet.ora -->
SQLNET.INBOUND_CONNECT_TIMEOUT = 120

The listener(s) will need to be restarted after these changes as will RMAN scripts.

This will eliminate any premature inbound timeouts when RMAN is attempting to connect and run the script.
However, if the error continues, then SQL*Net tracing will be recommended to see where the abnormal connection failure is occurring.

Applies to:

Oracle Server - Enterprise Edition - Version: 11.2.0.1 and later   [Release: 11.2 and later ]
Information in this document applies to any platform.
Symptoms


The duplicate database from active failed with the following errors : 

ORA-17629: Cannot connect to the remote database server
ORA-17627: ORA-12154: TNS:could not resolve the connect identifier specified
ORA-17629: Cannot connect to the remote database server

Cause

For Active Duplication you need to connect to the target and Auxiliary DB using net service name ,even if you are running RMAN at the Auxiliary DB.
The net service name to connect to the Auxiliary DB should also be configured at the target Database.

In the tnsnames.ora on the machine of the TARGET database, there are 2 services created to connect to auxiliary database that have the same "service name" but different configuration.

Solution


1. To be sure that the tnsnames.ora file of each machine (machine where is the source database and machine where is the auxiliary database) has the service name to connect to auxiliary database.

2. Verify that there are not duplicate service_name with different configuration in the tnsnames.ora file.

As per the Step 2 of the below RMAN doc :
http://download.oracle.com/docs/cd/B28359_01/backup.111/b28270/rcmdupdb.htm#i1008564

When duplicating from an active database, you must first have connected as SYSDBA to the auxiliary instance by means of a net service name. This net service name must also be available on the source database instance.
The source database instance, to which RMAN is connected as TARGET, uses this net service name to connect directly to the auxiliary database instance.


Double check using the following commands on the TARGET and AUXILIARY
% tnsping
% tnsping

Once this is executed for the TARGET and AUXILIARY, it should return the same 'connect' information.
