1、10gR2 CRS Install),10gR2 CRS和RDBMS安装主要步骤,安装CRS软件 10.2.0.1(base version)-从DVD安装安装数据库软件 10.2.0.1(base version),选择只安装软件 从DVD安装安装Oracle 10.2.0.3 patchset 10.2.0.3 patchset包括CRS和数据库软件部分-先把CRS升级到10.2.0.3-再把数据库软件升级到10.2.0.3 参考10.2.0.3 patchset readme文件用数据库软件的$ORACLE_HOME/bin目录下的dbca创建RAC数据库安装CRS 和数据库 bundl

9、unning xclock.Do not proceed unless xclock displays properly.,Click Next,Verify Path is properly pointing to intended$CRS_HOME location,click Next.NOTE:Typo in the screenshot above.Path should be/u01/app/crs/product/10.2.0/crs,Click Next,NOTE:The installer seems to make some assumptions regarding na

10、ming conventions for private interconnect and vip names.It assumes that the local install node is going to be part of the cluster and adds it to the Cluster Nodes list with the default naming convention.In this case,the defaults didnt match the networking setup of the system.Click Edit and change th

11、e names appropriately.,After entering the correct names,click OK.Then click Add to add additional Cluster Nodes with the appropriate network names.The Public node and Virtual Host names should properly resolve in DNS and the/etc/hosts file.Use nslookup to verify that the names properly resolve in DN

12、S.Verify both the fully qualified and short names.All should resolve properly.Also verify reverse lookups using nslookup to resolve the IP addresses to the proper host names.,Click OK,Once all the Cluster Nodes have been added,click Next.Note about Cluster naming conventions.Adopt a naming conventio

13、n for clusters throughout an organization with though toward monitoring these clusters using Grid Control.If cluster names are defined in a haphazard way then this can cause problems later when configuring Grid Control.For instance,no duplicate cluster names should be used.Consult Grid Control docum

14、entation for more details on the cluster configuration process.,The installer automatically identifies the systems ethernet interfaces and differentiates between private and public IP subnets(10.and works are assumed to be private)This should be set up the same on all the servers that will be in the

15、 cluster.They should all be on the same subnet.In this case we want to use eth0 as the public interface and eth1 for the private interconnect.Veth31 will not be used as part of the configuration.Click its line in the list and then click Edit.,Indicate Do not use by selecting the proper radio button,

16、click OK.,Click Next,In 10gR2 the OCR and voting disk can be multiplexed.In this case,5 raw devices have been set up on the shared storage prior to installation in order to provide locations for these files(raw3 raw7).After filling out the locations for each appropriately,click Next.,Click Next.,Cli

17、ck Install,Wait for completion of the installation.The CRS software will be automatically copied to the other cluster nodes(assuming that ssh is properly configured beforehand).,Once the software has been copied to all nodes in the cluster you are prompted to run a couple of scripts as root on each

18、node.It is very important that they not be run simultaneously.Run orainstRoot.sh on each node one at a time and then run root.sh first on the install node.root.sh formats the OCR and voting disk and brings up the CRS stack on the first node.This can take a few minutes.Wait until the root.sh script f

19、inishes before running it on subsequent nodes.Run root.sh on subsequent nodes one at a time.On each node that root.sh is run it updates the OCR and voting disks with info about that node and then brings up the CRS stack.Below is the output of these scripts on the install node and the second node.,In
