NBU调用RMAN时报RMAN-01009错误

同事在测NBU调用RMAN进行备份时，出现如下错误：

Both single and double quotes(’ or ”) are accepted for a quoted-string.
Quotes are not required unless the string contains embedded white-space.
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-00552: syntax error in command line arguments
RMAN-01009: syntax error: found “dot”: expecting one of: “double-quoted-string, equal, identifier, single-quoted-string”
RMAN-01007: at line 2 column 1 file: command line arguments
Script ./hot_database_backup.sh
==== ended in error on Fri Feb 20 15:47:36 CST 2009 ====

发生这个错误的原因是：热备脚本hot_database_backup.sh 中的$RMAN_LOG_FILE变量来自shell变量$0，使用了相对路径，而有些版本rman不支持相对路径，因此执行时报错。

解决方法是给$RMAN_LOG_FILE予绝对路径：

修改$RMAN_LOG_FILE变量：

原来：

RMAN_LOG_FILE=${0}.out

修改成：

$RMAN_LOG_FILE=`pwd`/${0}.out
