Information in this document applies to any platform.
For the purposes of this document, the following fictitious environment is used as an example to describe the procedure:
Pluggable Database Names: SOURCE_PDB, TEST_PDB,
Tablespace Name: TEST_TBS
Table Name: TEST_TABLE
Directory Name: /u02/app/oracle/oradata/ORCL/ and all subdirectories
A PDB containing encrypted tablespaces can be successfully cloned and opened at the primary and active dataguard standby site without any errors.
However, a select of a table in the encrypted tablespaces will fail with ORA-28304 at Standby site. Oracle RAC(Real Application Clusters) and Automatic Storage Management (ASM) can be excluded from a condition to see this symptom.
