What is domain index in oracle
In the future please use COPY & PASTE so we can see what you do & how Oracle actually responds > If I am to drop this index and recreate it, will it have any impact to the table using this index? Yes, there will be some impact. What is the alternative if you decided to not drop & recreate it? The Oracle*Text utility (formally called Oracle ConText and Oracle Intermedia) allows us to parse through a large text column and index on the words within the column. Unlike ordinary b-tree or bitmap indexes, Oracle context, ctxcat and ctxrule indexes can be set not to update as content is changed. Since most standard Oracle databases will use the ctxcat index with standard relational tables, you must decide on a refresh interval. To encounter this, Oracle introduced function-based indexes. A function-based index calculates the result of a function that involves one or more columns and stores that result in the index. The following shows the syntax of creating a function-based index: (A) all indexes, along with their columns, on objects accessible to the current user in Oracle database (B) all indexes, along with their columns, on objects in Oracle database Query was executed under the Oracle9i Database version. Hi, I remember an issue where domain indexes were taking approximately 1 hour per domain index to import, so if you had 24 domain indexes, it would take a day to import them. There is a bug fix, but I don't remember what versions had the issue and what versions are fixed. Dropping an index is where you delete or remove an index from the database. Actually, the term “drop” refers to any object in Oracle (e.g. table, view, synonym), not just indexes. To drop an index in Oracle SQL, you use the DROP command. DROP INDEX index_name; An index is a schema object that contains an entry for each value that appears in the indexed column(s) of the table or cluster and provides direct, fast access to rows. Oracle Database supports several types of index: Normal indexes. (By default, Oracle Database creates B-tree indexes.) Bitmap indexes,

A domain index is usually used in cartridge development. In
Can anybody tell me how to create a domain index and what is the use of it. Thanks
When you create an index on a table that already has data, Oracle Database must use sort space to create the index. The database uses the sort space in memory allocated for the creator of the index (the amount for each user is determined by the initialization parameter SORT_AREA_SIZE ), but the database must also swap sort information to and In the future please use COPY & PASTE so we can see what you do & how Oracle actually responds > If I am to drop this index and recreate it, will it have any impact to the table using this index?

The domain index is used for indexing non-traditional data, such as LOB data, video data and other non-textual columns. Domain Index: Using the Indextype schema object, an application-specific index can be created. Such an index is called a domain index since it is used for indexing data in application-specific domains. A domain index is an instance of an index which is created, managed, and accessed by routines supplied by an indextype.
