EXP-00056: ORACLE error 942 encountered with db_link
 


Question:  I tried to export the table from client database 8.1.7 using DBLINK from our database 10.1.0.3 and got this error "EXP-00056: ORACLE error 942 encountered". Please help out.

Export: Release 10.1.0.3.0 - Production on Wed Oct 12 10:27:38 2005

Copyright 1982, 2004, Oracle. All rights reserved.


Connected to: Oracle8i Enterprise Edition Release 8.1.7.0.0 - 64bit Production

Enter array fetch buffer size: 4096 >

Export file: expdat.dmp > test.dmp

(2)U(sers), or (3)T(ables): (2)U > 3

Export table data (yes/no): yes >

Compress extents (yes/no): yes >

EXP-00056: ORACLE error 942 encountered
ORA-00942: table or view does not exist
EXP-00000: Export terminated unsuccessfully

Answer by Edward Stoever:  I  have always used exp as a single command, not interactively. It is claiming the table does not exist, but I don't see it asking for a table - yet. (weird)

Why not try it as a single command.... like this:

exp scott/tiger file=emp.dmp tables=(emp,dept)

I  think that you are breaking the second rule there, and you should be exporting using an 8.1.7 client.

The Oracle documentation notes:

Whenever you are moving data between different releases of the Oracle database, the following basic rules apply:

    * The Import utility and the database to which data is being imported (the target database) must be the same version.
    * The version of the Export utility must be equal to the earliest version of the source or target database.

For example, to create an export file for an import into a later release database, use a version of the Export utility that is equal to the source database. Conversely, to create an export file for an import into an earlier release database, use a version of the Export utility that is equal to the version of the target database.
