10 Administering Oracle ACFS With Oracle Enterprise Manager

Creating Oracle ACFS Volumes and File Systems

To create an Oracle ACFS volume, perform the following steps.

1. Access the Disk Groups page from the Oracle ASM home page.

2. Click the Volumes link in the General tab of the Disk Group page. See Figure 10-6.

3. Click Create in the Volumes tab of the Disk Group page.

   Enter the volume name (maximum 11 characters), disk group name that contains the volume, and the initial size of the volume. You can also select the redundancy setting for the volume and the region settings for primary and mirror extents.

Figure 10-1 shows the Oracle ASM Create ASM Volume page.

To create an Oracle ACFS file system on a volume in a disk group, perform the following steps.

1. Access the Volumes tab of the Disk Group page. See Figure 10-6.

2. Select an existing volume in the disk group and click Create ASM Cluster File System.

   Figure 10-2 shows the ASM Create Oracle ACFS file system page.

   The compatibility parameters COMPATIBLE.ASM and COMPATIBLE.ADVM must be set to 11.2 or higher for the disk group. See "Disk Group Compatibility Attributes".

3. On the ASM Create Oracle ACFS file system page, enter the information to create a file system. You can optionally register and mount the file system.

   You need to enter the volume name. You can enter an optional volume label.

   You can optionally choose to register and mount the file system when it is created. Select a mount point from available directories.

   Enter the host credentials needed to execute the command when prompted. To register or mount a file system, you need root or administrator privileges. For information about the registry process, see "About the Oracle ACFS Mount Registry".

   After a directory has been selected, click Show Command to have Oracle Enterprise Manager generate the commands that you can execute at an operating system prompt. Examples of commands on a Linux system are:

   /sbin/mkfs -t acfs -b 4k /dev/asm/volume1-361
   /sbin/acfsutil registry -f -a /dev/asm/volume1-361 /oracle/acfsmounts/acfs2
   /bin/mount -t acfs -rw /dev/asm/volume1-361 /oracle/acfsmounts/acfs2
   

   You can also generate the commands to register or mount an Oracle ACFS file system on the ASM Cluster File System tab. See Figure 10-3.

Viewing and Modifying Oracle ACFS Volumes and File Systems

To view information about Oracle ACFS file systems, click the ASM Cluster File System link in the ASM home page.

Figure 10-3 shows the ASM Cluster File System tab in Oracle Enterprise Manager. This tab lists all of the Oracle ACFS associated with the Oracle ASM instance.

On this page, you can choose to mount, dismount, delete, create snapshot, view content, register, and deregister a selected file system. In addition, you can create a file system, mount all file systems, or dismount all file systems.

For each Oracle ACFS, the columns provide information for Mount Point, Availability, State, Snapshots, Used (%), Used (GB), Size (GB), Allocated Space, Redundancy, Volume, and Disk Group. Redundancy, Volume, and Disk Group columns are on the far right of the page and are not shown in illustration. The mount point, snapshots, volume, and disk group are provided as links to further information.

To view information about a specific volume, click the volume name in the Volume column on the ASM Cluster File System page.

Figure 10-4 shows the General tab of the ASM Volumes page.

To view information about a file system, click the link in the Mount Point column on the ASM Cluster File System page.

Figure 10-5 shows the General tab of the ASM Oracle ACFS page.

To view information about a disk group for an Oracle ACFS, click the disk group name in the Disk Group column on the ASM Cluster File System page. The General tab of the Disk Group page displays as shown in Figure 9-4.

To view information about volumes in a disk group, click the Volumes tab at the top of the Disk Group page.
