Home -> Community -> Mailing Lists -> Oracle-L -> RE: OPS and redos
Hi ,
We are trying to get a LINUX Cluster and RAC setup to work correctly and it looks promissing sofar (<sarcasm>no thanks to the excellent documentation Oracle provides on the subject </sarcasm>) many guesses & visits to technet and metalink forums later we have two instances up and running and the whole thing seems to be working properly. The only thing I can't seem to get to work is that from my client I connect fine to one node (using service_name) and get no listener for the other node while the listener is up and running. Trying the same from the server works fine. It connect to both instances w/o problem usin the service_name (not sid or alias)
Does anybody have good documentation on sqlnet, tnsnames and listener.ora files in RAC environment (O91R2)?
Also is it correct that 9iR2 does not have the oranm binary
TIA Jack
Scott

Please respond to
ORACLE-L
John, I actually have never sat down tested to see when Oracle actually does the redo kick. I do have a OPS and RAC test environment so I may have to see how big the GAP gets before Oracle starts doing log archive switches on the idle node.
The only reason I have heard why Oracle does this kick is to keep on-line redo logs archiving off of idle instances, while other active instances generate redo and archive on-line logs. The intent is to keep archive streams from all participating instances close to each other in time, so that a set of archived logs for all redo streams/instances can easily be identified and managed for backup or recovery. Also used in executing the ALTER SYSTEM ARCHIVE LOG CURRENT command, which is used to cause all instances to archive their current logs.
I know Anjo has some detail on this feature. So he may be able to provide more information.
