Options for setting up Mobius to use TLI, HPNS or OE sockets. Also documents how to correct an error that may occur when upgrading from older releases of the stack, or from v6.0 SP1 and lower to SP2 or higher.
Please be aware that this document is based on use of Mobius Direct View 6.2.
First a brief overview of the differences.
Mobius Direct View is coded such that it can be implemented over the TCPaccess stack using a variety of configurations.
Implementing TLI sockets is the default way to run the application as defined in the Mobius documentation.
TLI is the TCPaccess proprietary socket interface, and the oldest supported by the stack.
The method for implementing this changed slightly at the SP2 level, so if you are upgrading from SP1 or prior, some minor changes may be needed to run Mobius.
Implementing OE (USS) sockets requires
A few customers may be running Mobius using OE sockets, but most use HPNS.
Implementing HPNS generally requires
We have multiple customers running Mobius VDR and Document Direct using HPNS.
Configuring VDR to use TLI sockets at TCPaccess 6.0 SP2 and above
TCPaccess had previously supplied its own version of the SASLINK(LSCNCOM) module that uses the proprietary TLI socket interface.
As of SP2, that process was changed to use the module supplied by SAS, which tries to use USS or HPNS sockets, depending on what is available.
The fastest way to remedy the situation is to run UMODLSC, which is located in the TCPaccess SAMP library.
This usermod recreates the old CA version of LSCNCOM (with aliases) that is by default placed in the TCPaccess.LOAD library.
Since the module will NEVER be called from within the stack, you can run the UMODLSC while the stack is active.
The resulting LOAD library must then be placed BEFORE the SASLINK in your Mobius STEPLIB, and everything will work as before, with the exact same configuration you had in Mobius when running over the lower level of TCPaccess.
We recommend utilizing HPNS or OE if possible, but it is not mandatory.
Configuring VDR to use OE (USS) sockets
We have not been able to determine when it should be one as opposed to the other so please refer to the Mobius documentation for clarification.
