When creating an Oracle ADVM volume for an Oracle ACFS file system that is intended to store database files, use the ASMCMD volcreate
command or the SQL ALTER
DISKGROUP
ADD
VOLUME
SQL statement rather than the ASMCA tool to ensure that the column striping is set to 1. For information about the volcreate
command, refer to "volcreate". For information about the ALTER
DISKGROUP
ADD
VOLUME
statement, refer to "Managing Oracle ADVM Volumes in a Disk Group".
Oracle ASM Configuration Assistant enables you to create or configure an Oracle ADVM volume, as shown in Figure 14-1.
Right click a selected volume in the Oracle ASM Configuration Assistant screen to display the configuration options menu.
The menu includes options to:
Enable disabled volumes and disable enabled volumes
View status details
Resize volumes that have not been mounted on an Oracle ACFS file system
Delete volumes
There are options for creating a volume, enabling all volumes, and disabling all volumes.
Figure 14-1 Oracle ASM Configuration Assistant Configure ASM Volumes Page
Click Create to display the dialog for creating a volume. You must provide a unique volume name for the existing Oracle ASM disk group that you select from the list of disk groups. You must also specify the size for the volume. You can optionally choose to display advanced options for creating a volume which enables you to specify the redundancy level and striping characteristics. For information about the advanced options when creating a volume, refer to "volcreate".
The compatibility parameters COMPATIBLE.ASM
and COMPATIBLE.ADVM
must be set to 11.2
or higher for the disk group to contain an Oracle ADVM volume. To use Oracle ACFS encryption, replication, security, or tagging, the disk group on which the volume is created for the file system must have compatibility attributes for ASM
and ADVM
set to 11.2.0.2
or higher. See "Disk Group Compatibility Attributes".
Before creating an Oracle ADVM volume on AIX, ensure that the necessary user authorizations have been created. For information, refer to "Oracle ACFS Command-line Tools for the AIX Environment".
