Rebuild the indexes using unrecoverable
I am trying to accomplish the following tasks through the | The UNIX and Linux Forums. SEGMENT_NAME||' REBUILD UNRECOVERABLE TABLESPACE Alter index
After the index has been read, Oracle will replace the old index tree in the same spot in the tablespace as the old index. For even faster execution time, the unrecoverable clause can be used with the rebuild command. Listing 8.9 The output from rebuilding the indexes alter index DON.DON_EK rebuild tablespace INDX_1; index rebuilt
You can remedy index fragmentation by reorganizing or rebuilding an index. For partitioned indexes built on a partition scheme, you can use either of these methods on a complete index or a single partition of an index. Rebuilding an index drops and re-creates the index. After understanding the significance of fragmentation in indexes of MS SQL Server, it becomes essential to recognize and rebuild the indexes. For rebuilding the fragmented indexes, we have discussed various methods of rebuilding index in SQL Server. Users can accomplish this task in two different manual and automatic manners as mentioned above.

I am trying to accomplish the following tasks through the shell script: 1. How to reorganize and rebuild index: Using SQL Server Management Studio: In the Object Explorer pane navigate to and expand the SQL Server, and then the Databases node. Expand the specific database with fragmented index. Expand the Tables node, and the table with fragmented index. Expand the specific table.
Rebuild all indexes for a table in offline mode. ALTER INDEX ALL ON XXXMYTABLEXXX REBUILD Rebuild one specified index for a table in offline mode. ALTER INDEX XXXMYINDEXXXX ON XXXMYTABLEXXX REBUILD Solution 2. Fragmentation. Fragmentation is an issue in tables that regularly have entries both added and removed. Check fragmentation percentage
2 Jul 2010 of course, is that unrecoverable is a deprecated option so you shouldn't be using it even though it still works. If you rebuild an index unrecoverable, it is the operation that is SQL> alter index t3_i1 rebuild unrecoverable;. You must have tablespace quota to modify, rebuild, or split an index partition or to a different value for logging in the REBUILD clause, then Oracle Database uses the UNRECOVERABLE is not a valid keyword for creating partitioned or
Right-click the index you want to reorganize and select Rebuild. In the Rebuild Indexes dialog box, verify that the correct index is in the Indexes to be rebuilt grid and click OK. Select the Compact large object column data check box to specify that all pages that contain large object (LOB) data are also compacted.

rebuild is a "bulk operation". it is true that SOMETIMES, disabling an index, doing a large bulk load, re-enabling and rebuild the index is FASTER than "leaving the index in place during the load". This is true for single partition tables (normal tables) as well as partitioned tables.
Alter index rebuild online: During a online index rebuild, Oracle will make a snapshot log on the target table to hold DML activity, read the table in a full-table scan (read consistent), build the new index and then apply the changes from the snapshot log after the index has been rebuilt. You can use NOLOGGING and PARALLEL with the online rebuild: NOLOGGING: You can also use the NOLOGGING option for super-fast index rebuilding. The only danger with using nologging is that you must re-run the create index syntax if you perform a roll-forward database recovery. Using nologging with create index can make index rebuilding up to 30% faster. You can remedy index fragmentation by reorganizing or rebuilding an index.
