Description
Whether Model 204 uses special record security keys for Parallel Query Option/204 remote users
Valid PQOSYS settings are:
| Setting | Meaning |
|---|---|
| X'00' | No special record security key is generated. The system manager must ensure that record security keys for local and remote users are unique. |
| X'80' | Model 204 provides a special record security key for remote users.
The Store, Find, and For Record Number statements use a record security key that is a concatenation of the user's record security ID (either their login user ID or their record security key from a subsystem definition) with a period (.) followed by the value of the CCAIN LOCATION parameter of the user's node. Trailing blanks are stripped from both the record security ID and the LOCATION part of the record security key. For local users, the record security key is the user's usual record security ID (that is, without any concatenation). |
You cannot reset PQOSYS after the Model 204 run is initialized.
Setting PQOSYS to X'80' requires extra disk space, because the value of each record security key stored by the system includes the period sign and the LOCATION parameter. Setting PQOSYS to the default minimizes disk space use.
