ORA-23327: imported deferred rpc data does not match string of importing db tips

Oracle Error Tips by Burleson Consulting


ORA-23327: imported deferred rpc data does not match string of importing db
Cause: Deferred rpc queues were imported from a database with a different global name or operating system than importing database.

Deferred rpc data should only be imported into a database with the same global name and hardware and operating system.

MOSC documentation has many important aspects of ORA-23327.  For instance, on Oracle Enterprise Edition (Version:, a problem in which full import, due to ORA-23327, can hang or fail. 

In Oracle 9i, an export done on a platform, and import done on a different platform (which is included in RPC object), causes a cross-platform of the full export/import, which Oracle does not allow.

Though it would normally be advised to use a schema export and/or drop all replicated objects, Oracle 9i doesn't have a script to allow the removal of replicates objects.

Because of this, Oracle docs give a workaround so that the ORA-23327 can still be resolved:

1. Use schema based import instead of full import

2. Do the following action to avoid the export of the RPC objects:

on the source database:
connect / as sysdba
create table sav_expact$ as select * from expact$;
truncate expact$;
do the full export
insert into expact$ select * from sav_expact$;
drop sav_expact$;

Use the resulting dmp file to import onto the other platform.
