ORA-01017 Invalid Username Password when connecting to 11g database from 9i client

Question

I m trying to connect to a schema on 11g  v11 2 0 1 0  from a PC with 9i  v9 2 0 1  client  It seems to connect fine to some schemas  but not this one - it comes back with a ORA-01017 Invalid Username Password error every time   The username and password are DEFINITELY correct - can anyone think of a reason why this wouldn t work    Are there any fundamental incompatibilities between 9i and 11g

I had a similar issue some time ago  You must be careful with quotes and double quotes  It s recommended to reset the user password  using a admin credentials   ALTER USER user name IDENTIFIED BY new password    But don t use double quotes in both parameters

I had a similar problem recently with Oracle 12c  I created a new user with a lower case password and was able to login fine from the database server but all clients failed with an ORA-01017  The fix turned out to be simple in the end  reset the password to upper case  but took a lot of frustrating effort to get there

Oracle 11 G and 12 C versions suggest to use more complex passwords  Although there is no issues during the user creation  The password must be alphanumeric and with special character   Verify the password version and status of the user   select   from dba users where username    lt user name gt     Amend it to be like below in case of 11G 12C   alter user  lt user name gt  identified by Pass2019     Now test connection

Credentials may be correct and something else wrong  I based my pluggable DB connection string on its container DB  Instead of the original parent example com service name the correct appeared to be pluggable example com

I had the same error  but while I was connected and other previous statements in a script ran fine before   So the connection was already open and some successful statements ran fine in auto-commit mode  The error was reproducable for some minutes  Then it had just disappeared  I don t know if somebody or some internal mechanism did some maintenance work or similar within this time - maybe   Some more facts of my env    11 2 connected as  sys as sysdba operations involved     reading from all tables  all views and granting select on them for another user

I know this post was about 11g  but a bug in the 12c client with how it encrypts passwords may be to blame for this error if you decide to use that one and you   Don t have the password case-sensitivity issue  i e  you tried ALTER SYSTEM SET SEC CASE SENSITIVE LOGON   FALSE and resetting the password and still doesn t work   Put quotes around your password in your connection string and it still doesn t help  You ve verified all of your environmental variables  ORACLE HOME  PATH  TNS ADMIN   and the TNS ADMIN registry string at HKLM Software Oracle KEY OraClient12Home is in place  You ve verified your connection string and user name password combination works in Net Manager  and You can connect using SQL Plus  Oracle SQL Developer using the same credentials   All the basic checks  Fix   Try setting HKLM System CurrentControlSet Control Lsa FIPSAlgorithmPolicy Enabled to 0 in the registry  regedit  to disable FIPS  Oracle ManagedDataAccess and ORA-01017  invalid username password  logon denied ORA-01005 error connecting with ODP Net https   community oracle com thread 2557592 start 0 amp tstart 0 https   dba stackexchange com questions 142085 ora-01017-invalid-username-passwordlogon-denied 142149 142149

If all else fails  try resetting the password to the same thing  I encountered this error and was unable to work around it  but simply resetting the password to the same value resolved the problem

The tip on Oracle s OTN    Don t type your password in TOAD when you try to connect and let it popup a dialog box for your password  Type the password in there and it will work  Not sure what they ve done in TOAD with passwords but that is a workaround  It has to do with case sensitive passwords in 11g  I think if you change the password to all upper case it will work with TOAD  https   community oracle com thread 908022
