About Changing z/OS Passwords from Client Computers
To change z/OS passwords from client computers, set the DB2 extended security option (EXTSEC) to YES . The default DB2 value for extended security is NO . There are two ways to set the extended security option to YES :
- In the DSNTIPR installation panel, change EXTENDED SECURITY to
YES .
- In the DSN6SYSP macro within the DSNZPARM creation job, set option EXTSEC to YES.
Setting the extended security option to YES enables the following two functions:
- Users on client workstations can change their z/OS passwords without signing onto TSO.
- Siebel Business Applications receive descriptive error codes generated by DB2 when security violations occur.
