Spooled files
The scenario: want to stop programmers from using a production OUTQ.
If the developers have either *JOBCTL or *SPLCTL, and the OPRCTL(*YES) parameter is specified on the OUTQ, the developers will be able to use and work with the OUTQ. One way to correct this is to turn the OPRCTL parameter on the OUTQ to *NO.
Assuming programmers have *JOBCTL, here is what I would do....
- Make the OUTQ *OPRCTL(*NO)
- Create a Group Profile for all developers
- Add the Group Profile to the OUTQ with an authority of *EXCLUDE
- Give the authorized user Group(s) *CHANGE (authorized users could be *PUBLIC now that the programmers are excluded.)
- If there are any *JOBCTL or *SPLCTL users (SysOpers?) who you want to be able to manage the OUTQ, give them *CHANGE authority as well.

Security System Values
WRKSYSVAL SYSVAL(*SEC) Working with system values dealing with security should be done carefully. One should read the latest information at the IBM Knowledge Center at Security system values
QPWDMAXLEN
In addition to the information available at Maximum Length of Passwords (QPWDMAXLEN) one should be aware of these considerations when going above 8 characters:
- Configuring the IBM i SSH, SFTP, and SCP Clients to Use Public-Key Authentication
- There were some things dealing with "File Transfer Subroutine" (QY2FTML) but try to find documentation on that.
- If you find any other concerns, then by all means, please update this page.
