ORA-20783: 
Oracle GoldenGate DDL Replication setup: 
*** Please move GOLDENGATE to its own tablespace 
ORA-06512: at line 34 

I've read the script, it seems that the problem can be fixed like this: 
$export ALLOW_SHARED_TABLESPACE='TRUE' 

As explained in install doc, http://docs.oracle.com/cd/E35209_01/doc.1121/e35957.pdf


"Create a default tablespace for the Oracle GoldenGate DDL schema. This
tablespace must be dedicated to the DDL schema; do not allow any other schema
to share it.  AUTOEXTEND  must be set to  ON for this tablespace, and the tablespace
must be sized to accommodate the growth of the GGS_DDL_HIST  and  GGS_MARKER  
tables. The GGS_DDL_HIST  table, in particular, will grow in proportion to overall
DDL activity."
