These documents, and other related product information, can be found on both the documentation CD ROM that shipped with your product, or at: http://webdocs.numaq.ibm.com/


Problem Report Summary

This section describes the known problems in the ptx/OSI Transport software. The number that appears in parentheses in the title of each problem report is the problem-tracking-system number assigned to the report.


Fixed Problems

The following bugs were fixed in this release:


Open Problems


osid Daemon -v Option Can Cause Panic (237888)

Problem: Using the OSI daemon osid -v repeatedly to debug the OSI configuration can result in a panic.

Workaround: Before invoking osid -v, make sure that ptx/OSI Transport is not running. Use the menu system to stop the transports.


Documentation Additions

This section of the Release Notes provides information that was too late to be included in the published manuals.


osistat - Endpoint Support

The osistat utility can only show up to 400 endpoints.


ositrace - Invalid PDU Display

The ositrace utility can only display valid PDUs, such as CR. Invalid PDUs may cause the utility to loop.


Kernel Parameters

In cases of high numbers of connections or heavy usage (load), the following kernel parameter values are recommended for ptx/OSI Transport to operate properly. Use the menu system to modify the parameter values.

OSI_TP0_PCB            1000
OSI_TP0_NSAP 100
OSI_TP0_ROUTE 64
OSI_TP4_PCB 1000
OSI_TP4_NSAP 100
OSI_TPCL_PCB 1000
OSI_TPCL_NSAP 4
OSI_CLNP_SUBNET 16
OSI_CLNP_REASM 64
OSI_CLNP_ROUTE 128
OSI_SNDCF_VC 128
OSI_SNDCF_SNET 50


NPI Changes

Two changes have been made to the internal NPI network layer interface: UNITDATA and BIND.


ATTENTION

The NPI interface is an undocumented and unsupported interface.



NPI UNITDATA Change

The NPI interface for UNITDATA has been changed. The DEST_length structure member is now set to the length of the NSAP address. Previously, DEST_length was set to the length of the NSAP structure, which included the length of the address.


NPI BIND Change

The NPI interface for BIND has been changed. You can now pass just the network selector to the bind interface. Passing only the selector causes it to be concatenated with the network address. Previously, the NPI interface required both the network address and selector.
