Performing An Export using dbms_datapump from a Logical Standby Database

We have Oracle RAC with ASM 11.2.0.1 and Data Guard installed on Linux Red Hat environment.

We have a requirement to connect to a stand-alone database (sqlplus / @<stand-alone database> then call a Oracle PL/SQL package we created that uses a database link to connect to the logical standby database and perform an export. The stand-alone database has a database link to the logical standby database that is working. However, the export fails because Oracle can't create the master table on the logical standby without disabling dataguard...finishing the export...then reenabling dataguard.

Has anyone successfully exported schemas from a logical standby database? If so, how did you do this?

Howdy, Stranger!
