APPLIES TO:
Oracle Database - Enterprise Edition - Version 10.1.0.2 to 11.2.0.0 [Release 10.1 to 11.2]Information in this document applies to any platform.
***Checked for relevance on 11-Mar-2013***
PURPOSE
The purpose of this document is to clarify the functionality of GSD in 10g and above.
SCOPE
This article is informational and intended for any user.
DETAILS
The function of GSD (10g and above) is to service requests for 9i RAC management clients and therefore when there are no 9i databases present, there is nothing for GSD to do. Consequently, there will be no impact on a RAC cluster if GSD is offline and 9i is not used.
If gsd fails to start due to whetever reasons then best thing is to work with Oracle support to analyze and fix the issue. Until that time, gsd can be temporarily disabled.
In 11.2 GSD is disabled by default and the service will show as target:offline, status:offline.
Disable GSD (pre 11.2)
After confirming that there are no 9i databases being used you can disable GSD by adding 'exit 0' after the initial comments in the script $ORACLE_HOME/bin/gsdctl where $ORACLE_HOME is the home from which nodeapps are running (i.e. crs home).
# "") echo "****ORACLE_HOME environment variable not set!"
# echo " ORACLE_HOME should be set to the main"
# echo " directory that contains Oracle products."
# echo " Set and export ORACLE_HOME, then re-run."
# exit 1;;
#esac
exit 0 ## Manually added as a temporary workaround
A backup of the original script should be made before making the above change.
Disable GSD (11.2)
You may want to disable GSD after you upgraded all your Oracle9i RAC databases.
srvctl stop nodeapps
srvctl disable nodeapps -g
srvctl start nodeapps
Enable GSD in 11.2
srvctl enable nodeapps -g
srvctl start nodeapps

Oracle 10G RAC 安装 完成之后，在某些情况下（尤其是在 aix 环境中），GSD服务进程状态可能是offline或者unknown。而且可能导致CRS启动十分缓慢。
GSD进程是Oracle 10G 与 Oracle 9i 通信的进程。如果机器上不存在Oracle 9i，可以通过如下方法禁用GSD来解决这个问题。
详细的介绍见 metalink doc：429966.1
禁用GSD服务的方法是在各个node上，修改$CRS_HOME/bin/gsdctl文件，在#esac行后增加 exit 0
操作过程如下：
操作要在rac的每个节点上完成
[@more@]备份gsdctl文件
