Hi list, 64-bit 10.2.0.4 on RHEL 5.1 Anyone know a reason why this OS script will not find the index: $ORACLE_HOME/bin/sqlplus -s `/home/oracle/<OWNER>` <<EOF begin execute immediate 'analyze index <OWNER>.<SYSTEM_GENERATED_LOB_INDEX_NAME> validate structure'; end; / exit; EOF It throws: ERROR at line 1: ORA-01418: specified index does not exist ORA-06512: at line 2 Same error stack if connected as sysdba. The index does exist - from dba_lobs. However, using the same system generated LOB index name at a SQL*Plus prompt [logged in as the owner] works. Lastly, with a named LOB index (non-system generated), the procedure will work. Any help is appreciated, Rich
