Objective: To learn how to design the ASM assembly language program in VC to improve the underlying application capability.
Compilation in VC does not require additional compilers and connectors, and can handle some things that cannot be handled in VC, and can be used in C variables, so it is very
Oracle ASM (Automatic Storage Management System) is a database file storage management system officially provided by oracle. Compared with other file storage systems, AMS has specific advantages in load balancing, performance optimization, and redundancy protection. Currently, ORACLE recommends that the database use AMS to store the corresponding files of the database. In 11g RAC mode, you can only use ASM
ASM is an outstanding new feature in Oracle Database 10 Gb. It provides file system, logical volume manager, software RAID and other services in a platform-independent manner. ASM can strip and mirror disks, so as to add or remove disks and automatically balance I/O when the database is loaded to delete "hot spots ". It also supports direct and asynchronous I/O and uses the Oracle Data Manager API introduce

For databases with large space capacity, in addition to the above factors, another important factor is the number of ASM diskgroups and the size of each asm disk required by the DISK group. ASM disk groups are not too many, and names can be normalized as much as possible. For example, they can be
For Oracle network configuration, we usually use negmgr or netca to connect the client to the database instance. You can also connect to the ASM instance from a client. However, Oracle does not provide a tool for us to complete the configuration. We can manually configure the listener and the client tnsnames. This section describes and provides examples.

The present document provides a clear example about how to rename an ASM diskgroup on release 11gr2.
Solution
1) First of all, the desired diskgroup needs to be dismounted (from each node if this is a RAC configuration ):
# asmcmd umount DATA
2) Verify that the desired diskgroup was dismounted:
# asmcmd lsdg
