Oracle 10G RAC - 归档参数格式导致归档至ASM时出错的问题

 10G RAC在ASM中存放归档日志参数正确设置
log_archive_dest_1        string      location=+RECOVERY/JTPROD
在利用vmware workstation进行共享磁盘，当设置log_archive_dets_1为‘+RECOVERY/JTPROD/archfolder’类似格式时，归档时会导致磁盘不一致，归档文件也不能够正常使用，包括crosscheck与backup archivelog all等常用的管理操作。

错误如下alter日志：
SUCCESS: diskgroup ARCH was mounted
archivelog header validation failure for file +ARCH/jtprod/1_13_772105560.dbf
archivelog header validation failure for file +ARCH/jtprod/1_15_772105560.dbf
Mon Jan 09 13:38:29 CST 2012
SUCCESS: diskgroup ARCH was dismounted

调试过程如下：
RMAN>backup database plus archivelog;

ORA-19563: archived logheader validation failed for file

RMAN>crosscheck archivelog all;该文件为failed。

RMAN>list expired copy;显示这些归档无效，不能被使用。

RMAN>delete expired coyp;只好将之删除。

解决
当log_archive_dest_1调整为location=+RECOVERY/JTPROD是则不再报错。
SQL>alter system set log_archive_dest_1='location=+RECOVERY/JTPROD' scope=spfile sid='JTPROD1';
SQL>alter system set log_archive_dest_1='location=+RECOVERY/JTPROD' scope=spfile sid='JTPROD2';
log_archive_dest_1scope=both修改后spfile和memory可以立马生效.

 

同时如果还有类似错误需要进行
RMAN> allocate channel for maintenance type disk;
allocated channel: ORA_MAINT_DISK_1
channel ORA_MAINT_DISK_1: sid=133 instance=JTPROD1 devtype=DISK
RMAN> change archivelog all crosscheck;

RMAN> release channel;

released channel: ORA_MAINT_DISK_1

补充说明
当手工删除了数据库的归档文件后，要执行以下脚本进行同步：
RMAN> allocate channel for maintenance type disk;
RMAN> change archivelog all crosscheck;
RMAN> release channel;
当手工删除了数据库的RMAN备份文件后，要执行以下脚本进行同步：
RMAN> allocate channel for maintenance type disk;
RMAN> crosscheck backup;
RMAN> delete expired backup;
RMAN> release channel;
如果目标数据库物理对象发生了变化，如添加数据文件，应用如下命令同步：
RMAN>resync catalog;
