ORA-20783:
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'



其实export ALLOW_SHARED_TABLESPACE='TRUE' 这个方法不是好方法。

GoldenGate 对DDL的配置要求如下:

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."
