During storage migration yesterday, when operating on the items in the ASM disk group, a title error occurs, as shown in the following figure. The reason is as follows:If the disk group is created using the asmca graphical tool, the default value of compatible. ASM is 11.2. If you use the create diskgroup SQL command to create a disk, the default value is 10.1, which must be manually modified. Therefore, yo

1. What is ASM? ASM is called Automatic Storage Management (Automatic Storage Management). It is a new feature launched by Oracle 10 Gb. This is a volume manager provided by Oracle to replace the LVM provided by the operating system. It not only supports single-instance configuration, but also supports multi-instance configuration such as RAC. It will bring great convenience to the Oracle database administr

RAID services. ASM supports strip and disk images, so that the disk can be added or removed when the database is loaded, and the I/O can be automatically balanced to delete the "Hotspot ". It also supports direct and asynchronous I/O and uses the Oracle Data Manager API introduced in Oracle9i (simplified I/O system call interface ). ASM is implemented and deployed as a separate Oracle instance. It only nee
