RMAN-10003: unable to connect to target database、ORA-01017: 使用者名稱/口令無效; 登入被拒絕
今天遠端協助處理一個RMAN無法分配備份通道的問題
備份腳本里run部分如下:
run{ allocate channel d1 device type disk connect 'sys/[email protected]'; allocate channel d2 device type disk connect 'sys/[email protected]'; backup format '/u01/testdb/testdb_%s_%R_%T.arc' archivelog all delete all input; release channel d1; release channel d2; }
報錯如下:
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 d1 RMAN-10008: could not create channel context RMAN-10003: unable to connect to target database ORA-01017: 使用者名稱/口令無效; 登入被拒絕
雖然無法分配備份通道,但已經收到ORA-01017,說明連線串TESTDB1和TESTDB2配置沒錯,測試連線證實:

sys使用者遠端登入需要讀取密碼檔案,如果密碼檔案損壞或丟失都將無法登入,檢查密碼檔案:
果然是密碼檔案orapwtestdb1出問題了.通過重建密碼檔案或修改密碼檔案的許可權可以解決問題:
$ orapw file=$ORACLE_HOME/dbs/orapwtestdb1 password=oracle entries=5 force=y
如果不知道這些引數是什麼意思,可以檢視命令幫助:
$ orapwd help=y
Usage: orapwd file=<fname> entries=<users> force=<y/n> ignorecase=<y/n> nosysdba=<y/n>
where
file - name of password file (required),
password - password for SYS will be prompted if not specified at command line,
entries - maximum number of distinct DBA (optional),
force - whether to overwrite existing file (optional),
ignorecase - passwords are case-insensitive (optional),
nosysdba - whether to shut out the SYSDBA logon (optional Database Vault only).
There must be no spaces around the equal-to (=) character.
重建密碼檔案之後就可以連線成功
