hi, I've just set up a 9.2.0.4 standby database and have been getting the following messages every day. Timing out on NetServer 1 prod=39901,cons=37325,threshold=2560 ORA-16166: LGWR timed out on Network Server 1 due to buffer full condition. No action is required since the log file transfer will be attempted via ARCH Sun Jan 16 02:34:14 2005 Errors in file /u01/app/oracle/admin/test01/bdump/test01_lgwr_12800.trc: ORA-16166: LGWR network server failed to send remote message LGWR: I/O error 16166 archiving log 3 to 'ddb03ps' Sun Jan 16 02:34:14 2005 Errors in file /u01/app/oracle/admin/test01/bdump/test01_lgwr_12800.trc: ORA-16166: LGWR network server failed to send remote message The source database is a test database and there are no workload generated on the database. According to metalink, a way to solve the problem is to increase the ASYNC buffer size. I've increased it to 20480 but I'm still getting the same error message. Also, I do not understand why would my buffer be full when I have absolutely nothing running on the source? Does anyone has any clue what is going on or how can I troubleshoot the problem? From Note:247129.1 - "As a best practice define your remote archive destination as such: service=<tns alias> LGWR ASYNC=20480 reopen=15 max_failure=10 net_timeout=30" Thanks.
