About Converting to Oracle Flex ASM

You can convert an Oracle ASM configuration to an Oracle Flex ASM using ASMCA. This functionality is only available in an Oracle Grid Infrastructure 12c configuration. For information about using ASMCA, refer to "Getting Started With the ASMCA GUI Tool". For

Note:

  • If you plan to introduce databases before Oracle Database 12c Release 1 (12.1) into a cluster configured with Oracle Flex ASM, you must ensure that Oracle ASM instances are running on all nodes in the cluster, including nodes that are added in the future. To ensure this requirement for the Oracle Flex ASM configuration, you must set the count of Oracle ASM instances to ALL with the SRVCTL modify asm command. For information about administering Oracle Flex ASM with SRVCTL commands, refer to "Administering Oracle Flex ASM".

  • For additional considerations, refer to the Notes in "About Setting Up Oracle Flex ASM".

Before you convert an Oracle ASM configuration to an Oracle Flex ASM, you must ensure the following:

ASMCA informs you if any requirement, such as storing an ORAPWD file in a disk group, has not been met before starting the conversion.

Figure 3-3 shows the Configure ASM: ASM Instances page that enables you to perform operations on selected Oracle ASM instances.

To complete the Oracle Flex ASM conversion, ASMCA generates the converttoFlexASM.sh script that must be run as privileged user only on the local node where ASMCA is running. Figure 3-5 shows the ASM Conversion dialog box with the script that must be run.
