Just to follow up. The issue has been resolved after I changed registry key to local_only = false ocrconfig_loc = G:\cdata\crs\data.ocr on the node. G drive is the one that can be seen from both nodes. Thanks for the help. Guang -----Original Message----- The values should be the same. I assume the OCR locations are pointing to the same OCR devices? Though I don't like the name of "local.ocr". Makes me wonder if there's more wrong there. Pete -----Original Message---- 2-node Rac on windows, oracle version =10.2.02, crs version =10.2.03 I tried to start OracleCRService on one node and it faied (the other node is OK). <snip> I found my node has registry key "ocrconfig_loc" values different on two nodes: One this node: local_only = true ocrconfig_loc = F:\oracle\product\10.2.0\db_1\cdata\localhost\local.ocr On the other node (which everything is fine there): local_only = false ocrconfig_loc = G:\cdata\crs\data.ocr My question: should ocrconfig_loc setting be the same on two nodes? I could not figure out the root cause of my problem. -- //www.freelists.org/webpage/oracle-l
