ASM Learning Notes _ ASM installation

Refer to the for your operating system for details on installing ASM.

1 ASM's installtion can be done by DBCA.

2 if you are using ASM in a non-RAC environment, you need to start the CSS service with the script $ORACLE_HOME/bin/localconfig add before installing ASM

The role of CSS service in a single instance remains to be confirmed?

Just start the CSS service to enable communication between the ASM instance and the RDBMS instance

The Cluster Synchronization Services (CSS) daemon is required to enable synchronization between ASM and its client

Database instances.

How to start CRS,CSS,EVM under a single instance

After n attempts, it finally succeeded.

Possible problems

1 because there are two versions of Oracl installed on the same node: 9iJing 10g. There are two ORACLE_HOME, causing confusion.

In an environment with multiple ORACLE_HOME, it seems possible to set the environment variable through / opt/oracle/product/10gr2/bin/localconfig reset

/ opt/oracle/product/10gr2/bin/localconfig $ORACLE_HOME

Is that so? Several attempts were unsuccessful

2 delete the temporary IPC Socket files in which LISTENER connects with each background process before each attempt

Rm-f / var/tmp/.oracle/*

Rm-f / tmp/.oracle/*

Rm-f / usr/tmp/.oracle/*

3 start monitoring
