2222: Index name is not unique (TimesTen)

Question

I have created two indexes on different materialized views with the same name in TimesTen and now cannot drop neither of them. If try to I get the following error message:

2222: Index name is not unique

Could you please advise me how could I get rid of one (or at least both) of these indexes?

Thank you!

Answer 1

Oracle doesn't permit the creation of index with the same name in the same schema. Are your indexes in seperate schemas? if Yes, then please specify your schema.index_name while deletion.To check the schemas of index , you can query all_indexes.

select * from all_indexes where index_name = 'put your index name here';

Then you can log in to one of the schemas and run delete schema_name.index_name. It must be a privilege issue hence you are getting an error

Answer 2

To drop indexes for Materialized Views [or tables] of the same name in two different schemas, you need to either:

1. Log into the first schema and drop the MV index Log into the second schema and drop the MV index

2. As the instance administrator [the OS user who you installed TimesTen as] and qualify the index to be dropped by the schema. eg

   ttIsql yourDbDSN drop schema1.index; drop schema2.index;

Answer 3

Specify the table name (or materialized view name) in the drop index query.

It should work.

Ex. like below.

DROP INDEX schema_name.index_name_01 FROM schema_name.table_name_01;
