Hello All, Good Morning! Hope every one is doing well!! I have a question/problem while configuring the RAC 10g on windows 2003 servers using VMware. I have installed vmware on windowsxp and then I installed windows2003 servers with two nodes in vmware. I can ping RAC1 from RAC2 and vice-versa. while installing the crs I entered the node information according to the host file. But I am gettitng the error message that cannot reach RAC1 or it is unavailable. The host file on both the nodes are as below.. RAC1: # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost.localdomain localhost #Public 192.168.2.101 rac1.localdomain rac1 192.168.2.102 rac2.localdomain rac2 #Private 192.168.0.101 rac1-priv.localdomain rac1-priv 192.168.0.102 rac2-priv.localdomain rac2-priv #Virtual 192.168.2.111 rac1-vip.localdomain rac1-vip 192.168.2.112 rac2-vip.localdomain rac2-vip RAC2: # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host 127.0.0.1 localhost.localdomain localhost #Public 192.168.2.101 rac1.localdomain rac1 192.168.2.102 rac2.localdomain rac2 #Private 192.168.0.101 rac1-priv.localdomain rac1-priv 192.168.0.102 rac2-priv.localdomain rac2-priv #Virtual 192.168.2.111 rac1-vip.localdomain rac1-vip 192.168.2.112 rac2-vip.localdomain rac2-vip Please advice how may I proceed. I am doing this configuration for the first time. Thanks Nilesh -- Soni Temples & Softwares are more or less the same, first we build them and then we pray ;)
