Hi Christo >but it doesnt tell you what the crs_profile,=20 >crs_getenv and etc commands do. >And that's what I am looking for. In "Oracle Real Application Clusters - Administration and Deployment = Guide 10g Release 2" beta draft there's a new appendix entitled "High = Availability Oracle Clusterware Command-Line Reference and C API". = Therefore very soon you should be able to have the information you are = looking for, at least for 10gR2.=20 HTH Chris PS: I'm doing some beta testing in single-instance mode only. Therefore = I don't know what they changed in CRS, i.e. I don't know if this = documentation can be relevant for 10gR1 as well... Anyway, in my = opinion, when it is out, makes sense to give it a look. -- //www.freelists.org/webpage/oracle-l
