Altering SERVICE Objects
Altering SERVICE Objects
SERVICE objects set default protocol values for the network, transport, session, and
presentation layers and ACSE of an OSI/AS subsystem. Use the SCF ALTER command
to alter the attributes of SERVICE objects—the OSI manager process must be started.
To alter the Layer 3 SERVICE object, you could use a command like the following:
ALTER SERVICE $OSIM.#L3, X25REMOTENET DATEXP
This command configures all X25AM subdevices for the DATEX-P X.25 network.
To alter the Layer 4 SERVICE object, you could use a command like the following:
ALTER SERVICE $OSIM.#L4, RECVSECURITY “MONAR”
This command specifies that the string “MONAR” must be present in all incoming
CR-TPDUs.
To alter the Layer 5 SERVICE object, you could use a command like the following:
ALTER SERVICE $OSIM.#L5, DISCONNECTTIMEOUT 1:30
This particular command sets the Session Layer disconnection and abort timer to one
and one-half minutes.
To alter the Layer 6 SERVICE object, you could use a command like the following:
ALTER SERVICE $OSIM.#L6, ARPPPDUSENTPROTERRORGROUPTHLD 100
This command sets a specified threshold to 100.
To alter the ACSE SERVICE object, you could use a command like the following:
ALTER SERVICE $OSIM.#ACSE, APABORTSTHLD 2000
This command sets a specified threshold to 2000.
By altering the attributes of an OSI/AS SERVICE object, you establish a default
configuration for all connections within a particular OSI layer. Nevertheless, you can
configure connections that use particular SNPA, NSAP, and TSEL addresses with
protocol values that override the defaults specified by the respective SERVICE object.
The following paragraphs describe how you use PROFILE objects to set protocol values
that affect only the connections that use particular OSI layer addresses.
Adding PROFILE Objects
You can add PROFILE objects to an OSI/AS subsystem whenever the OSI manager is
started. OSI/AS uses L3PROFILE objects to configure subdevices for NSP processes
(X25AM and TLAM on D-series releases or PAM on G06 and above releases),
L4PROFILE objects to configure subdevices for TSP processes, and L5PROFILE
objects to configure subdevices for TAPS processes.
After you add a PROFILE object, you need to assign it to one or more OSI addresses.
Assigning Layer 3 Profiles
