PRGO-02066：Cannot create a read-write snapshot of an ASM Cluster File System (ACFS) on ASM disk group "{0}".
错误码
错误描述：Cannot create a read-write snapshot of an ASM Cluster File System (ACFS) on ASM disk group "{0}".
错误原因：An attempt to upgrade a database with zero downtime was rejected because the database had data files on an ACFS, but the ASM Dynamic Volume Manager (ADVM) compatibility attribute for the disk group containing the ACFS was less than 11.2.0.3.0, which meant that a snapshot of the data files could not be created.
解决方法：Set the ADVM comptatibility attribute for the indicated disk group to 11.2.0.3.0 or higher, and then retry the operation.
