Steps to resolve ORA 14287 cannot REBUILD a partition

by

Introduction: – In this post we will cover ORA 14287 cannot REBUILD a partition. If any index status is unusable then we will have to identify the same and rebuilt as mentioned below.

How to resolve ORA 14287 cannot REBUILD a partition?

SQL>SELECT OWNER, INDEX_NAME,” FROM DBA_INDEXES WHERE STATUS = ‘UNUSABLE’ UNION SELECT INDEX_OWNER, INDEX_NAME, PARTITION_NAME FROM DBA_IND_PARTITIONS WHERE STATUS = ‘UNUSABLE’ UNION SELECT INDEX_OWNER, INDEX_NAME, SUBPARTITION_NAME FROM dba_ind_subpartitions WHERE STATUS = ‘UNUSABLE’;

Suppose here we will try to rebuild partition index, then we can face error as “ORA-14287: cannot REBUILD a partition of a Composite Range partitioned index”.

Here we can see the index ‘EGO_MTL_SY_ITEMS_EXT_TL_N1’ have sub-partitioned index.

SQL>select ‘alter index ‘||index_owner||’.’||index_name|| ‘ rebuild partition ‘||partition_name||’ online compute statistics;’ from dba_ind_partitions where index_name =’EGO_MTL_SY_ITEMS_EXT_TL_N1′;

Rebuild index using alter index rebuild partition.

SQL> alter index EGO.EGO_MTL_SY_ITEMS_EXT_TL_N1 rebuild partition AG_ZERO online compute statistics;

alter index EGO.EGO_MTL_SY_ITEMS_EXT_TL_N1 rebuild partition AG_ZERO online compute statistics

ERROR at line 1:

ORA-14287: cannot REBUILD a partition of a Composite Range partitioned index

Solution:-

Check the sub-partition index and rebuild the sub-partion index instead of partitioned index.

Check out the index details.

 

SQL> select index_name name,partition_name partition,subpartition_name Subpartition,status from all_ind_subpartitions i where   I.INDEX_NAME=’EGO_MTL_SY_ITEMS_EXT_TL_N1′;

Once rebuild the index, verify the indexes as below.
