Linux platform Oracle 11g DG Test Environment Quick Build reference

Environmental Status:Two virtual hosts A and b:1. A machine has installed ASM storage for Oracle 11g instance reference: HTTP://WWW.CNBLOGS.COM/JYZHAO/P/4332410.HTML2. b machine installed system, configuration and directory structure are consistent with a machine/U01 + 3 ASM Disk DG Deployment Planning:

first, pre-preparation1.1. A machine pack copy/u01/app to B machine (includes grid and Oracle Software installation directory)

# tar -zcvf app.tar.gz app

Decompress the machine B. Make sure that the second operation is completed before decompressing.

# pwd
