歸檔報錯

oracle中log_archive_dest_n和log_archive_dest不能共存，也就是隻能使用其一

ORA-16019: cannot use LOG_ARCHIVE_DEST_1 with LOG_ARCHIVE_DEST or LOG_ARCHIVE_DUPLEX_DEST

可以執行如下命令清除：

SQL> alter system set log_archive_dest='' scope=both;

歸檔有時候會報錯：
ARC0：Beginning to archive log# 4 seq# 2772
     Current log# 3 seq# 2773……
ARC0: Failed to archive log# 4 seq# 2772
ARCH: Completed to archiving log#4 seq# 2772
建議init引數修改如下：
log_archive_max_processes=2
#log_archive_dest = '/u05/prodarch'
log_archive_dest_1 = 'location=/u05/prodarch'
log_archive_dest_state_1 = enable
