In our company we use Golden Gate to replicate databases. Our DBAs found following issues which prevent Golden Gate from replicating schema used by Stash:

1. Indexes and constraints with system generated names are not supported

CONSTRAINT_TYPE TABLE_NAME
------------------------------- ------------------------------
P AO_CFE8FA_BUILD_STATUS
P AO_FB71B4_PUBLIC_KEY
P AO_6978BB_RESTRICTED_REF
P AO_6978BB_PERMITTED_ENTITY
U WEIGHTED_PERMISSION
P PLUGIN_SETTING

P - Primary Key
U - Unique Key

Solution: Primary/Unique keys and indexes assigned to them should be named

2. Tables With No Primary Key or Unique Index
Table Rows
------------------------ --------
CS_ATTRIBUTE 906
HIBERNATE_UNIQUE_KEY 1
HT_STA_PR_ACTIVITY
ID_SEQUENCE 14

Solution: Primary or Unique keys should be created for those tables.
