Password backup and reset in 19c

Vinay KFeb 5 2025

we are doing a refresh of Dev database from Prod. Oracle version is 19.24

Previously in 11g and 12c we had a way of backing up the existing schema password in encrypted form and restore it back. But in 19c this is not working

Do we have any other methods or doing this in 19c ?

in 12c we used to do this

SQL> SELECT spare4 FROM sys.user$ WHERE name = 'SCOT';

SQL> alter user test identified by values ‘ <PWD Frome above step>’;

Hi Salomon,

please have a look at this blog post written by @ulrike-schwinn-oracle :

https://blogs.oracle.com/coretec/post/easy-sql-statement-tracking-in23c

I hope this answers your question, if not, please shout!

@martinbach-oracle - No, it doesn't answer my question. Article you pointed to shows uses:

SQL> alter system set sql_history_enabled=true scope=both;

And in my post I said “Works fine when enabled on system level”. My question was about

SQL> ALTER SESSION SET SQL_HISTORY_ENABLED = TRUE;

where I showed SQL history was NOT captured even though it should be based on SQL_HISTORY_ENABLED:

Modifiable **ALTER SESSION**, ALTER SYSTEM

As per the article I shared the situation is as follows at the moment

  • You must enable SQL history PDB-wide (only a DBA can do that) so there's a certain level of control over the feature
  • Your session has access to the SQL history
  • If you don't want to record anything, set sql_history_enabled to false.

I'm currently assessing if that's intended behaviour (in which case the documentation should be amended) or a feature not working as it should (in which case it needs fixing). The parameter is indeed session-modifyable, but not in the sense you expected.

We'll keep you posted.

Do you mean it must be enabled on system level and not on session level and all session can do is disabe it for the session?

Yes,

that's correct as of Oracle Database Free 23.6.

Thanks Martin, I hope this will be added to 23AI docs soon.
