indexler gelmemişse

I have used this one in the past and it's very helpful when working on particular schema changes. Hope it's helpful to Oracle DBA in need.

Note: The script will NOT capture the indexes created by the user 'SYS'. The script will capture indexes for clusters, but the create statement for these indexes will fail because it DOES NOT include the keyword CLUSTER. If the create index of a cluster is executed, it will result in an error 'ORA-00942 table or view does not exist' because it will be looking for a table of that name NOT A CLUSTER.

The other way of getting the indexes DDL is export with INDEXES=Y and then import will INDEXFILE=some file.sql

If you have any comments for improving the script - let me know.



REM
REM SCRIPT FOR CREATING INDEXES
REM
REM This script must be run by a user with the DBA role.
REM
REM Running this script will in turn create a script to build all the
REM indexes in the database. This created script, create_index.sql,
REM can be run by any user with the DBA role or with the 'CREATE ANY INDEX'
REM system privilege.
REM
REM The script will NOT capture the indexes created by the user 'SYS'.
REM
REM The script will capture indexes for clusters, but the create statement
REM for these indexes will fail because it DOES NOT include the
REM keyword CLUSTER. If the create index of a cluster is executed, it
REM will result in an error 'ora-942 table or view does not exist' because
REM it will be looking for a table of that name NOT A CLUSTER.
REM
REM NOTE: Indexes automatically created by table CONSTRAINTS will also
REM be INCLUDED in the create_index.sql script. It may cause a problem to
REM create an index with a system assigned name such as SYS_C00333.
