Hi List, can anyone give me some hints what - and how - this CRS is authenticating in $CRS_HOME/crs/auth ? There is surprisingly little information aroud. I'm having a SR at Oracle where we stumbling about this authentication, but it's hard to get any epiphany from the big red Oracle. A short summary of my issue here: I get an annoying ORA-29702 sometimes on my 11gR1 DBs (184.108.40.206.3 on Solaris10) the full error stack in alert.log is Errors in file xxxx.trc ORA-15032: not all alterations performed ORA-29702: error occurred in Cluster Group Service operation ORA-29702: error occurred in Cluster Group Service operation ERROR: error ORA-15032 caught in ASM I/O path Some weeks of investigations get me down to the 'authentication' of a rdbms-process to get allowance on the ASM DG to add a file or alias. (this is not 100% sure, but a good baseline for discussions). Now I'm searching for details about this authentication. So far I know the rdbms-process is asking ocssd (in fact an instance of the clsc_authent_thrd threads) for allowance to create a file in an ASM DG. This seems to be a kind of exclusive lock (in the DG?), and in some of my cases the permission does not come fast enough. For this permission, there is a kind of filesystem-handshake on $CRS_HOME/crs/auth (who the hell invited THIS communication!?) But now I have to dig down what is failing there. Some ideas come to my mind: is the ocssd clsc_authent_thrd thread just not answering fast enough? is the filesystem to slow to handle the requests? could it be an IO-issue on the disks of the FS? maybe some other process is just doing work on the DG and did not release it's 'lock' back to the clsc_authent_thrd? At the moment for me it looks as a kind of contention - but I doesn't know where (and how) to look next? Therefore once again, if you know anything about this authentication, please share it with me ;-) thank you Martin -- http://www.freelists.org/webpage/oracle-l
