ORA-01991: invalid password file ...
When trying to open (or mount) a database the following error is generated:
ORA-01991: invalid password file '...PWDOrcl.ora'
Where ‘Orcl’ is the SID of the database instance.
Typically some corruption of the password file, or possibly the password
file is for another database instance?
- If encountered when creating the database then it is because Oracle
expects to create the password file but it already exists. In this instance
database creation will have failed. Delete the password file and try
- If it is suspected that the password file is corrupt then try deleting
it and recreating it:
- Delete the existing password file.
- Create a new/replacement password file:
orapwd file=<path>\PWD<sid>.ora password=oracle
Use the same path as given in the Oracle error. The password
specified will be the new internal password.
These notes have been tested with Oracle 8.1.5 running
under Windows NT.
This page represents one page of many pages of notes I made whilst working
with Oracle 7 through to 10i. I now no longer work with Oracle databases,
but hope that these notes will continue to be of benefit to others.
