ORA-00257 :Learn how to troubleshoot for ORA-00257 archiver error. ORA-29913 :troubleshooting tips for the ORA errors like ora-29913: error in executing odciexttableopen callout, ora-29913: error in executing odciexttablefetch callout ORA-00911 : This post is for common causes of ORA-00911: invalid character in oracle with examples and resolution to help you complete the job Hope you like the content on ORA-01017 invalid username/password if you have thentication_services=none ,then also you may get this error Make sure the OS user is part of DBA group.Īlso check the sqlnet.ora. This can happen if the OS user where you are trying to use the above command is not member of dba group. (9) ORA-01017 using “sqlplus / as sysdba” For example: SQLNET.ALLOWED_LOGON_VERSION_SERVER=11 Password version can be checked as select username,password_version from dba_users Įdit the SQLNET.ORA file to change the SQLNET.ALLOWED_LOGON_VERSION_SERVER setting from the default, 12, to 11 or lower. If you have accounts that require 10G password versions, then to prevent accounts using that password version from being locked out of the database, you can change from an Exclusive Mode to a more permissive authentication protocol. The case-insensitive 10G password version is no longer generated. This parameter refers to the logon authentication protocol used for the server, not the Oracle Database release.īy default, Oracle no longer supports case-insensitive password-based authentication only the new password versions (11G and 12C) are allowed. Starting with Oracle Database 12c release 2 (12.2), the default value for the SQLNET.ORA parameter ALLOWED_LOGON_VERSION_SERVER is changed to 12. Review your options if you have earlier release password versions. This protocol requires case-sensitive passwords for authentication. The Oracle Database 12c release 2 (12.2) default authentication protocol is 12 (Exclusive Mode).
(8) Case-Insensitive Passwords and ORA-1017 Invalid Username or Password (7) This error can be encountered during RMAN active duplication also Cause The SYS password is not the same between the original/source database and auxiliary/duplicate database.ġ) Copy the password file from the original/source database to the auxiliary/duplicate database.Ģ) Run the following OS command "cksum" to check whether the password files are the same on both the original/source database and auxiliary/duplicate database. Tusc -afpo /tmp/tusc_user.output -aef sqlplus scott/ Truss -fea -o /tmp/truss_user.output sqlplus scott/
Strace -o /tmp/strace_user.output -cfT sqlplus Scott/ You can trace the call stack by using truss or trace command Linux: (6) Sometimes ,there could be other reason for the error and ORA-01017 is misleading error. With Oracle database 12c, in case Primary RAC database,we need to have password file at shared location orapwd file='+DATA/TEST/PASSWORDFILE/oraTEST' entries=10 dbuniquename=TEST password= Create the oracle password file using orapwd with same password on both the primary and standby side Make sure SYS user password is same on both the Primary and standby side. (5) You may get ORA-01017 error in dataguard environment and standby environment also (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = TEST))) Used TNSNAMES adapter to resolve the aliasĪttempting to contact (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1521)) oracle/product/11.2.0.4/network/admin/sqlnet.ora You can use tnsping command to check that also TNS Ping Utility for Linux: Version 11.2.0.4.0 - Production on 22-JUNE-2016 23:01:06Ĭopyright (c) 1997, 2014, Oracle.
(4) Check your tnsnames.ora to ensure that the TNS service is pointing to right database. If your $ORACLE_SID is set to the wrong database then you may get a ORA-01017 error because you are connecting to the wrong oracle database. (3) Check your $ORACLE_SID or $TWO_TASK environmental parameter. select username from dba_users where username ='' Check if the user ID exists as the username column in the dba_users view. (2) It may be that the user ID is invalid for the target system. SQL> ALTER SYSTEM SET SEC_CASE_SENSITIVE_LOGON = TRUE If it works, then you know the case sensitivity is the problem, you may want to alter the user password and write it somewhere to remember the case -sensitive password and then again enable the system parameter SQL> ALTER user test identified by TEST1 When the above parameter is set to true, the case sensitivity is on, You may disable it and check the connection again SQL> ALTER SYSTEM SET SEC_CASE_SENSITIVE_LOGON = FALSE Īnd the try connecting. SQL> SHOW PARAMETER SEC_CASE_SENSITIVE_LOGON
