Purpose
oramerge
can be used for merging the changes between two Oracle database
schemas into a third one. Depending on the existance/non-existance of schema
objects in the three schemas oramerge
does the right thing. If a schema
objects exists in all three schemas, the external tool merge3
will be used
for creating a merged version of the object (except for tables where the
appropriate ALTER TABLE
statements will be output if possible).
Options
oramerge
supports the following options:
connectstring1
(Oracle connectstring)Old version of database schema
connectstring2
(Oracle connectstring)New version of database schema
connectstring3
(Oracle connectstring)Schema into which changes should be merged
-v
,--verbose
(false
,no
,0
,true
,yes
or1
)Produces output (on stderr) while the database is read or written.
-c
,--color
(yes
,no
orauto
)Should the output (when the
-v
option is used) be colored? Ifauto
is specified (the default) then the output is colored if stderr is a terminal.-k
,--keepjunk
(false
,no
,0
,true
,yes
or1
)If true (the default), database objects that have
$
orSYS_EXPORT_SCHEMA_
in their name will be skipped (otherwise these objects will be considered as merge candidates).
Example
Output a script that merges the changes between user@db
and user2@db2
into user3@db3
:
$ oramerge user/pwd@db user2/pwd2@db2 user3/pwd3@db3 -v >db.sql
