Initiator-Identity and Filestore-Password Parameters
Initiator-Identity and Filestore-Password Parameters
The initiator-identity and filestore-password parameters in the F-INITIALIZE request
correspond, respectively, to the Guardian user ID and password on the Compaq system.
Optionally, a default user ID and password can be set up in the Compaq FTAM
configuration, allowing remote applications access to the responder and its VFS without
sending a user ID and password across the network.
If defaults are not configured, your application must specify a Guardian user ID that
allows access to the files in the VFS, along with its associated password.
Protocol-Error Counter
A protocol-error counter, whose value is configurable, specifies how many FTAM
protocol errors must occur before an event message is generated on the Compaq system.
These event messages can alert the Compaq problem solver to interoperability problems.
Increasing Responder Capacity
The Compaq system manager can increase responder capacity by doing one of the
following:
•
Increasing the maximum number of associations or attaches per responder process
•
Adding more responder processes
Increasing Responder Performance
The system manager can often increase system performance or throughput by doing one
or more of the following:
•
Configuring responder processes to run in different Compaq CPUs
•
Specifying a less fully occupied disk as the process swap volume
•
Adjusting the execution priority of various processes
•
Adjusting some of the parameters in the underlying OSI/AS configuration
Fault Tolerance
Compaq FTAM provides some fault tolerance if responder processes are configured to
run as NonStop process pairs, consisting of a primary process and a backup process.
When processes run as NonStop process pairs, the startup configuration information for
the primary process is checkpointed. If a hardware or software component fails, the
backup process takes over.
If the primary responder process fails, all outstanding Compaq FTAM associations, as
well as the associated OSI/AS connections, are aborted. The remote initiator receives
an F-P-ABORT indication. After a delay, the remote FTAM application can retry
establishing the association.
