1.没有设置log_archive_dest_1参数,归档文件没有同步

Mon Nov 07 17:46:12 2016
Using STANDBY_ARCHIVE_DEST parameter default value as USE_DB_RECOVERY_FILE_DEST
解决方法:
[oracle@dg2 dbs]$ vim initcheng.ora --添加归档文件的存放路径(primary和standby节点)
*.log_archive_dest_1='LOCATION=/u01/oradata/tong/archive valid_for=(all_logfiles,all_roles) db_unique_name=cheng'
[oracle@dg2 dbs]$
2.主库节点(primary)没有权限往log_archive_dest_1写入
ARCH: Archival stopped, error occurred. Will continue retrying
ORACLE Instance cheng - Archival Error
ORA-16014: log 4 sequence# 26 not archived, no available destinations
ORA-00312: online log 4 thread 1: '/u01/oradata/tong/sredo04.log'
Errors in file /u01/diag/rdbms/cheng/cheng/trace/cheng_arc1_6272.trc:
ORA-16014: log 4 sequence# 26 not archived, no available destinations
ORA-00312: online log 4 thread 1: '/u01/oradata/tong/sredo04.log'
解决方法:
[oracle@dg2 dbs]$ vim initcheng.ora --primary和standby都修改
*.log_archive_dest_1='LOCATION=/u01/oradata/tong/archive valid_for=(all_logfiles,all_roles) db_unique_name=cheng'
*.log_archive_dest_2='service=cheng LGWR SYNC AFFIRM valid_for=(online_logfiles,all_roles) db_unique_name=cheng'
[oracle@dg2 dbs]$
3.standby库没有开启闪回
db_recovery_file_dest_size of 2000 MB is 0.00% used. This is a
user-specified limit on the amount of space that will be used by this
database for recovery-related files, and does not reflect the amount of
space available in the underlying filesystem or ASM diskgroup.

4.standby控制文件损坏
SQL> alter database recover managed standby database disconnect;
alter database recover managed standby database disconnect
*
ERROR at line 1:
ORA-01665: control file is not a standby control file
SQL>
解决方法:
如果standby节点的控制文件损坏,备份primary的控制文件传过去
(1).primary节点备份控制文件
SQL> alter database create standby controlfile as '/tmp/1.ctl';
Database altered.
SQL>
[oracle@dg1 ~]$ scp /tmp/1.ctl oracle@dg2:/tmp/
(2).standby节点还原控制文件
[oracle@dg2~]$ cp -a /tmp/1.ctl /u01/oradata/tong/control01.ctl
[oracle@dg2~]$ cp -a /u01/oradata/tong/control01.ctl /u01/flash_recovery_area/tong/control02.ctl
5.primary和standby节点的归档日志不一至
dg1节点:
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /u01/oradata/tong/archive --归档路径与standby节点不一至
Oldest online log sequence 37
Next log sequence to archive 39
Current log sequence 39 --当前日志序列号与syandby不一至
SQL>
dg2节点:
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination ?/dbs/arch --路径两个节点必须一至
Oldest online log sequence 26
Next log sequence to archive 0
Current log sequence 37
SQL>
解决方法:
[oracle@dg1 ~]$ vim /u01/product/11.2.0.1/db_1/dbs/inittong.ora --修改pfile文件(两个节点)
*.log_file_name_convert='/u01/oradata/tong','/u01/oradata/tong'
*.db_file_name_convert='/u01/oradata/tong','/u01/oradata/tong'
