The value of the AFD_STATE
parameter of SYS_ASMFD_PROPERTIES
specifies whether Oracle ASMFD is configured for the Oracle ASM instance.
You can check the state of Oracle ASMFD with the ASMCMD afd_state
command. For example:
$ $ORACLE_HOME/bin/asmcmd afd_state ASMCMD-9526: The AFD state is 'LOADED' and filtering is 'DEFAULT' on host 'myhost'
For information about using the ASMCMD afd_state
command to determine the state of Oracle ASMFD, refer to "afd_state".
To determine if Oracles ASMFD is present on the host, you can also display the value of AFD_STATE
from SYS_CONTEXT
. You must run the query on the Oracle ASM instance.
If the value of AFD_STATE
is equal to NOT
AVAILABLE
, then Oracle ASMFD is not configured.
SQL> SELECT SYS_CONTEXT('SYS_ASMFD_PROPERTIES', 'AFD_STATE') FROM DUAL; SYS_CONTEXT('SYS_ASMFD_PROPERTIES','AFD_STATE') -------------------------------------------------------------------------------- NOT AVAILABLE
A value of CONFIGURED
means that Oracle ASMFD is completely set up and the Oracle ASM instance can register with the driver.
SQL> SELECT SYS_CONTEXT('SYS_ASMFD_PROPERTIES', 'AFD_STATE') FROM DUAL; SYS_CONTEXT('SYS_ASMFD_PROPERTIES','AFD_STATE') -------------------------------------------------------------------------------- CONFIGURED
