LRM-00112: multiple values not allowed for parameter 'userid'

Getting error while exporting


exp userid='/ as sysdba' full=y file=/dev/null log=/stage/$ORACLE_SID.log direct=y statistics=none
LRM-00112: multiple values not allowed for parameter 'userid'

EXP-00019: failed to process parameters, type 'EXP HELP=Y' for help
EXP-00000: Export terminated unsuccessfully

This is a syntax error which can be fixed by replacing userid='/ as sysdba' with userid="'/ as sysdba'"


Following command will work

exp userid="'/ as sysdba'" full=y file=/dev/null log=/stage/$ORACLE_SID.log direct=y statistics=none
