Accessing service tools
To access service tools, you can use dedicated service tools (DST), system service tools (SST), or IBM® Navigator for i.
The service functions available to you depend on the functional privileges you have. If you do not have the correct privileges, you cannot sign on to SST. If you have the appropriate functional privileges, you can manage service tools user IDs from SST or DST.
The following table outlines the basic differences in access methods between DST and SST.
| Characteristic | DST | SST |
|---|---|---|
| How to access | Physical access through console during a manual IPL or by selecting option 21 on the control panel. | Access through an interactive job with the ability to sign
on with QSECOFR or the following authorizations:

| How to authenticate | Requires service tools user ID and password. | Requires a service tools user ID and password. |
