同事备份遇到了一个报错，提示用户密码拒绝。经过确认用户和密码都没有问题，那可能是什么问题呢！
1、现象
<roidb01:orcl:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin>$ <roidb01:orcl:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin>$sh rman.sh Recovery Manager: Release 11.2.0.4.0 - Production on Tue Feb 13 22:12:56 2018 copyright (c) 1982,2011,Oracle and/or its affiliates. All rights reserved. connected to target database: ORCL (DBID=1483481154) RMAN> 2> 3> using target database control file instead of recovery catalog RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-12001: Could not open channel t1 RMAN-10008: Could not create channel context RMAN-10003: unable to connect to target database ORA-01017: invalid username/password; logon denied RMAN>
2、部分脚本内容
<roidb01:orcl:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin>$vi rman.sh
$ORACLE_HOME/bin/rman target / <<EOF
run{
allocate channel t1 device type disk connect 'sys/xxxx$2017_sys@orcl';
#发现这个密码里有特殊符号$
}
exit
EOF
3、解决方法
<roidb01:orcl:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin>$
<roidb01:orcl:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin>$cat rman.sh
$ORACLE_HOME/bin/rman target / <<EOF
run{
allocate channel t1 device type disk connect 'sys/xxxx\$2017_sys@orcl';
}
exit
EOF
shell 脚本中特殊符号需要使用\转义处理一下。
再次执行
<roidb01:orcl:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin>$sh rman.sh Recovery Manager: Release 11.2.0.4.0 - Production on Tue Feb 13 22:13:20 2018 copyright (c) 1982,Oracle and/or its affiliates. All rights reserved. connected to target database: ORCL (DBID=1483481154) RMAN> 2> 3> using target database control file instead of recovery catalog allocated channel: t1 channel t1: SID=46 device type=disK released channel: t1 RMAN>
小结：当我们在shell脚本里执行相关命令，一定要关注特殊符号的转义问题。
