Best way to compare two Databases
What is the best way to compare two databases. Especially
tables+columns, indexes+columns, constraints, views, stored procedures,
triggers.
It is not about data.
It is not possible to make a network connection to
the two databases, so a dblink is not a possible solution.
-------------------------
select table_name from s1.user_tables
minus
select table_name from s2.user_tables
&
vice versa
&&
for all the other objects in question
write sql the like
or use dbms_metadata for both schemas
and then use your favourite editor to compare the files will all that ddl
included
or take an exp from both schemas
imp <u>/<p>@sid file=your.dmp
fromuser=s1 show=yes log=s1.log
imp <u>/<p>@sid file=your.dmp
fromuser=s2 show=yes log=s2.log
then compare the logs and retrieve
the differences
-------------------------
Use OEM Change Management to take the diff between two
databases. Of course you would need OMS if want to take snapshots, but
for simple comparison - it's not neccessary
