TISERV UOW Descriptions

SET-SYSTEM-PARAM Operation
This UOW alters two system parameters maintained in the configuration directory: the
external objects capability (EXTOBJS-ENABLED field) and the system language
character map (SYS-LANG-CMAP-ID field). To alter these values, set the appropriate
PARAMS-TO-ALTER subfield to Y and enter new values in the corresponding
PARAM-VALUES subfield.
This UOW can only be used by applications with system administrator write
privileges; if the user or application does not have system administrator privileges,
E-SECURITY-VIOLATION is returned to the application.
A TMF transaction is required for this UOW; if one is not in progress when the UOW
is issued, E-BAD-TRANSACTION is returned.
The external objects capability, as reflected in the EXTOBJS-ENABLED field,
determines whether or not the external objects capability is enabled at your node. The
system is initialized with EXTOBJS-ENABLED set to Y, indicating that external objects
are enabled. After altering the value of the EXTOBJS-ENABLED field, you should stop
and then restart all servers.
If the external objects capability is enabled, then the TRANSFER delivery system
accepts all external object UOWs. However, if the external objects capability is
disabled, the TRANSFER delivery system rejects all UOWs that alter any current
attachment or that create a new one. Furthermore, the TRANSFER delivery system
does not transport items that contain external objects to a node where the external
objects capability is disabled; if your application requests such action, it receives an
error message for each recipient on the node.
In order for the external objects capability to be enabled, volume names must be
defined in the TRANSFER name directory; otherwise, if an external object UOW is
requested, E-NO-VOLUME-SPECIFIED is returned.
The SYS-LANG-CMAP-ID field determines the default national language in which
data is entered and displayed at your node, and the default character mapping used
with that language. See the discussions of the START-SESSION and
START-SESSION-B40 UOWs.
