I tried to setup ORACLE 11G dataguard on two servers. I follow document setup following: 1. remote_login_passwordfile = exclusive on both servers init.ora 2. orapwd file=orapwdT11DB.ora password=xxxx. I also transfer "orapwdT11db.ora" to another server and put under /home/app/oracle/product/11.1/dbs 3. "sys" password same like "orapwd" password After I startup both primary DB and Standby DB, I got ORA-16191 error. Anyone know what wrong it is? ================ alert.log message ===== Errors in file /home/app/oracle/diag/rdbms/t11db/T11DB/trace/T11DB_arc0_30623.trc: ORA-01017: invalid username/password; logon denied Error 1017 received logging on to the standby ------------------------------------------------------------ Check that the primary and standby are using a password file and remote_login_passwordfile is set to SHARED or EXCLUSIVE, and that the SYS password is same in the password files. returning error ORA-16191 ------------------------------------------------------------ Errors in file /home/app/oracle/diag/rdbms/t11db/T11DB/trace/T11DB_arc0_30623.trc: ORA-16191: Primary log shipping client not logged on standby PING[ARC0]: Heartbeat failed to connect to standby 'T11DBSTY'.
