Operating with Different Releases of Oracle ASM and Database Instances Simultaneously

Oracle Automatic Storage Management (Oracle ASM) 26ai supports Oracle AI Database 26ai or earlier software versions.

Note:

  • An Oracle ASM instance must be at Oracle ASM 26ai to support Oracle AI Database 26ai.

  • Refer to Oracle Exadata documentation for information about the Oracle AI Database versions that Oracle ASM supports when Oracle Exadata storage is present.

  • There are additional compatibility considerations when using disk groups with different releases of Oracle ASM and database instances.

When using different software versions, the database instance supports Oracle ASM functionality of the earliest release in use. For example, an Oracle Database 19c instance operating with an Oracle ASM 26ai instance only supports Oracle ASM 19c features.

The V$ASM_CLIENT view contains the SOFTWARE_VERSION and COMPATIBLE_VERSION columns with information about the software version number and instance compatibility level.

  • The SOFTWARE_VERSION column of V$ASM_CLIENT contains the software version number of the database or Oracle ASM instance for the selected disk group connection.

  • The COMPATIBLE_VERSION column contains the setting of the COMPATIBLE parameter of the database or Oracle ASM instance for the selected disk group connection.

You can query the V$ASM_CLIENT view on both Oracle ASM and database instances.
