Implementing Siebel eBusiness Applications on DB2 UDB for z/OS and OS/390 > Security Concepts for z/OS and OS/390 >

Changing Passwords from Remote Clients

In order to change z/OS and OS/390 passwords from remote client machines, 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, set the DSNZPARM EXTSEC=YES.

Setting the extended security option to YES enables the following two functions:

• Users on client workstations can change their z/OS and OS/390 passwords without signing onto TSO.
• Siebel eBusiness Applications receive descriptive error codes generated by DB2 when security violations occur.
