oracle rac RMAN-20242问题解决思路

环境 aix 730
数据库版本 oracle 10.2.0.5 +asm+RAC
在做数据库归档日志恢复时，提示以下错误：
Starting restore at 2012-08-06 14:40:12
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=1994 instance=ora2 devtype=DISK
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of restore command at 08/06/2012 14:40:13
RMAN-20242: specification does not match any archive log in the recovery catalog

解决方法: 恢复归档日志一定要跟线程号
