Configure AFD (ASM Filter Driver) and Prepare Disks for ASM


<<Back to Oracle ASM Main Page

How to Install and Configure ASM Filter Driver from Beginning Itself

Step1>  Install Oracle GI binaries
Install GI ( Grid Infrastructure Software) and Apply Latest PSU.  Follow the Steps from my post "How Install and Configure Oracle ASM"
Step2>Stop has
#crsctl stop has
CRS-2791: Starting shutdown of Oracle High Availability Services-managed resources on 'wdtest05'
CRS-2673: Attempting to stop 'ora.LISTENER.lsnr' on 'wdtest05'
CRS-2677: Stop of 'ora.LISTENER.lsnr' on 'wdtest05' succeeded
CRS-2673: Attempting to stop 'ora.evmd' on 'wdtest05'
CRS-2677: Stop of 'ora.evmd' on 'wdtest05' succeeded
CRS-2793: Shutdown of Oracle High Availability Services-managed resources on 'wdtest05' has completed
CRS-4133: Oracle High Availability Services has been stopped.
Step3> Configure AFD (ASM Filter Driver)
# asmcmd afd_configure
AFD-627: AFD distribution files found.
AFD-634: Removing previous AFD installation.
AFD-635: Previous AFD components successfully removed.
AFD-636: Installing requested AFD software.
AFD-637: Loading installed AFD drivers.
AFD-9321: Creating udev for AFD.
AFD-9323: Creating module dependencies - this may take some time.
AFD-9154: Loading 'oracleafd.ko' driver.
AFD-649: Verifying AFD devices.
AFD-9156: Detecting control device '/dev/oracleafd/admin'.
AFD-638: AFD installation correctness verified.
Modifying resource dependencies - this may take some time.

Step4> Configure Disk Discovery for AFD
Modify the below mentioned files as shown
# cat /etc/afd.conf
afd_diskstring='/dev/xvd*'
afd_filtering=enable
#cat /etc/oracleafd.conf
afd_diskstring='/dev/xvd*'
afd_filtering=enable
At this point AFD is configured you can verify the status as below
# asmcmd afd_state
ASMCMD-9526: The AFD state is 'LOADED' and filtering is 'ENABLED' on host 'wdtest05'
I would recommend to restart acfs before you proceed
#acfsload stop
#acfsload start
#lsmod | grep acfs
Step5> Label the Disks using AFD to be used by ASM
#asmcmd afd_label DATA01 /dev/xvdg
#asmcmd afd_label FRA01 /dev/xvdh
#asmcmd afd_label REDO01 /dev/xvdi
#asmcmd afd_lsdsk

ORA-46630: keystore cannot be created at the specified location

<<Back to DB Administration Main Page ORA-46630: keystore cannot be created at the specified location CDB011> ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '+DATAC4/CDB01/wallet/' IDENTIFIED BY "xxxxxxx"; ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '+DATAC4/CDB01/wallet/' IDENTIFIED BY "EncTest123" * ERROR at line 1: ORA-46630: keystore cannot be created at the specified location Cause  Creating a keystore at a location where there is already a keystore exists Solution To solve the problem, use a different location to create a keystore (use ENCRYPTION_WALLET_LOCATION in sqlnet.ora file to specify the keystore location), or move this ewallet.p12 file to some other location. Note: Oracle does not recommend deleting keystore file (ewallet.p12) that belongs to a database. If you have multiple keystores, you can choose to merge them rather than deleting either of them.

How to Switch Log File from All Instances in RAC

<<Back to Oracle RAC Main Page Switch The Log File of All Instances in Oracle RAC. In many cases you need to switch the logfile of the database. You can switch logfile using alter system switch logfile command but if you want to switch the logfile from all the instances you need to execute the command on all the instances individually and therefore you must login on all the instances. You can avoid this and switch logfile of all instances by just running the below command from any of the instance in RAC database SQL> ALTER SYSTEM SWITCH ALL LOGFILE;   System altered.
