script-move a list of indexes - particular set of tables in a tablespace

[AOrehek]

You can't MOVE indexes to another tablespace. You have to REBUILD indexes to move them!

Correct :
SELECT
'ALTER INDEX ' || index_name || ' REBUILD TABLESPACE P1ECP1_LT96K_X;'
FROM dba_indexes WHERE tablespace_name='P1ECP1_LT96K_D';
