In Oracle 11g, ASM supports both 10g and 11g databases. However, the ASM version cannot be less than the database version.Two parameters related to compatibility now:Compatible.rdbmsThe minimum supported version of the Oracle database.compatible.asmControls the data storage
ASM file allocation in a disk group
Oracle ASM striping
Oracle ASM strip has the following two purposes:
Distribute the Server Load balancer across all disks in the disk group.
Reduces I/O latency
ASM strip is divided into coarse-grained strip and fine-grained strip. Coarse-grained strip is used as a disk group to provide load balancing, while fine-grained strip can reduce the I/O latency of a specif

default, both attributes are set to 10.1. to use new features, you must promote these attributes.
Setting the compatibility attribute to an earlier version allows the client to access a later version of the disk group. For example, the Oracle 10g client can access the Oracle 11g ASM disk.

After a whim, I suddenly wanted to install Oracle10g and Oracle11g under OEL6. The two versions coexist to facilitate learning and experiment. This installation process is not difficult, if you have installed 10g and 11g respectively, I believe the specific operation is very easy. The most important thing is how to make the two versions coexist and work properly.The entire installation process has been tested on the virtual machine. The installation p

In terms of data Guard (later written as DG), we only focus on the following three types of parameters:
1. Parameters independent of database roles2. Parameters when the database role is primary3. Parameters when the database role is standby
Although DG has a lot of configuration parameters, we actually use only a few of
