In the alert log the following error occurs,

ORA-1632: max # extents 50 reached in index
INV.MTL_UNIT_TRANSACTIONS_N1

A similar error appears in the client application also, causing a rollback.

The tablespace on which this index has AUTOEXTEND set to ON, but the ORA erros is that the max extents 50 has been reached.

How do I overcome this?

Thanks.

With regards.
