Managing Oracle ACFS and Oracle ADVM With ASMCA

14 Managing Oracle ACFS and Oracle ADVM With ASMCA

Oracle ASM Configuration Assistant (ASMCA) provides utilities for managing Oracle Automatic Storage Management Cluster File System (Oracle ACFS) and Oracle ASM Dynamic Volume Manager (Oracle ADVM).

Oracle ASM Configuration Assistant (ASMCA) supports installing and configuring Oracle ASM instances, Oracle ASM disk groups, Oracle ASM Dynamic Volume Manager (Oracle ADVM) volumes, and Oracle Automatic Storage Management Cluster File System (Oracle ACFS) file systems. In addition, you can use the ASMCA command-line interface.

This chapter discusses the following topics:

For information about managing Oracle ASM instances and disk groups with ASMCA, refer to Managing Oracle ASM With ASMCA.

Note:

Some ASMCA functionality and menu options are only available in specific environments, such as an Oracle RAC configuration. For details about a specific ASMCA page, access the online help provided with the Help button.

ASMCA GUI Tool for Managing Oracle ACFS and Oracle ADVM

This section contains the following topics:

Managing Oracle ADVM Volumes with ASMCA

Note:

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.

Oracle ASM Configuration Assistant enables you to create or configure an Oracle ADVM volume.

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.

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.

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.

Before creating an Oracle ADVM volume on AIX, ensure that the necessary user authorizations have been created.

Managing Oracle ACFS File Systems with ASMCA

Oracle ASM Configuration Assistant enables you to create or configure an Oracle ACFS file system.

To configure an existing file system, right click a selected file system in the Oracle ASM Configuration Assistant screen to display the configuration options menu.

The menu includes options to:

View status details
Mount and dismount the file system
Resize the file system
Delete the file system
Display or execute the security commands
Create or delete snapshots

Some commands require root privileges, such as mounting a file system. ASMCA generates the command for you to run manually as root.

When creating Oracle ACFS file systems on Windows, run ASMCA as a Windows domain user who is also an administrator of the computer.

There are buttons for Create, Mount All, Dismount All, and Security and Encryption commands.

Oracle ASM Configuration Assistant enables you to create an Oracle ACFS file system.

Select Create, then select the type of Oracle ACFS file system you want to create and an existing Oracle ADVM volume from the lists. Specify the mount point field; the mount point must be an existing directory. The file system must be mounted to make it available. You can choose to enable the Auto Mount option. You can also provide a description of the file system in the Description field.

The mount command must be manually run as root or the Windows Administrator at an operating system prompt.

You can choose to create an Oracle ACFS file system for an Oracle Database.

Managing Security and Encryption for Oracle ACFS with ASMCA

Oracle ASM Configuration Assistant enables you to configure security and encryption for an Oracle ACFS file system.

You must initialize the security system as the first step in configuring security for an Oracle ACFS file system. You must also initialize the encryption system as the first step in encrypting an Oracle ACFS file system. You do not have to use both Oracle ACFS security and encryption on the same file system. If you decide to use both security and encryption, then encryption must be initialized and set before enabling encryption on a security realm.

In the dialog that displays, enter the information to specify the security administrator and the operating system group of the security administrator. You can choose to create a password protected wallet. After you complete the entry fields in the dialog, click Show Command to display the commands you must run as a root or Administrator user at an operating system prompt. For example:

# /sbin/acfsutil sec init -u grid -g asmadmin
# /sbin/acfsutil encr init

After security has been initialized, you can use the menu options to manage security and encryption for an Oracle ACFS file system.

The menu includes options to:

Set encryption
Enable and disable encryption
Prepare and enable security
Enable and disable security

Creating an Oracle ACFS File System for Database Use

To create an Oracle ACFS file system for database use, you can select the Create ACFS for Database Use from the disk group configuration options menu to display the dialog entry box.

Note:

In this dialog, you must enter:

Volume Name

This is the name of the Oracle ADVM volume you want to create.
Mount Point

This is the mount point for the file system where you want to install the database home. The file system that contains the database home should not be located under the Oracle Grid Infrastructure base (ORACLE_BASE for grid) directory.
Size in gigabytes (GB)

The default is 7 GB and the minimum recommended size.
Owner Name

This is the operating system name of the user that installs the database and owns the software in the database home.
Owner Group

This is the operating system group of the owner of the database home.

The mount point must be an existing directory. The file system must be mounted to make it available.

Select Automatically run configuration commands to run ASMCA configuration commands automatically. To use this option, you must provide the root credentials on the ASMCA Settings page.

The mount command may also be run manually as root or the Windows Administrator at an operating system prompt.
