log_archive_dest_1设置报错
DG搭建完之后，又报错： Tue Dec 22 16:24:33 2015 Errors in file /u01/app/oracle/admin/orcl/bdump/orcl_arc1_2994.trc: ORA-16014: log 8 sequence# 20 not archived, no available destinations ORA-00312: online log 8 thread 2: '/u01/app/orcl/onlinelog/stdby_redo8.log'

说的挺明显，就是归档路径有问题，
路径下没有归档：
[root@dbdg orcl]# ll total 0查看参数：
log_archive_dest_1 string LOCATION=/u01/app/oracle/orcl
VALID_FOR=(ALL_LOGFILES,ALL_RO
LES) DB_UNIQUE_NAME=orcl
原来是DB_UNIQUE_NAME指定错误。
修改：
SQL> alter system set log_archive_dest_1='LOCATION=/u01/app/oracle/orcl VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=orcldg' scope=both; System altered.
归档路径生成了归档
[root@dbdg orcl]# ll total 1436 -rw-r----- 1 oracle oinstall 174592 Dec 22 16:49 1_22_899013364.dbf -rw-r----- 1 oracle oinstall 1024 Dec 22 16:49 1_28_899013364.dbf -rw-r----- 1 oracle oinstall 98304 Dec 22 16:49 1_29_899013364.dbf
原来，log_archive_dest_1指定本机db_unique_name.
