New Features and Problems Fixed

1.1 RTR Version T5.2 EFT2

This section contains information speciﬁc to RTR Version T5.2 EFT2.

1.1.1 New Features

This section describes the following new feature in this release.

• HP Reliable Transaction Router supports 64-bit library on OpenVMS

Alpha

RTR is enhanced to extend the memory allocation capacity of RTR processes

by supporting 64-bit pointers on both Alpha and Integrity servers. Earlier it

was supported only on Integrity servers.

The 32-bit applications that use V3/V2 API does not require recompilation or

relinking to work with the 64-bit RTR library. An existing application, based

on V3/V2 API, that is compiled with a 32-bit and linked with an old RTR

library can work seamlessly with the 64-bit library.

To make use of the 64-bit pointers, the applications will require recompilation

with the

pointer_size=64

qualiﬁer of the C/C++ compiler.

Restriction

Applications that use V2 API cannot be compiled with the

pointer_size=64

qualiﬁer because RTR does not support this API in the 64-bit format.

Applications will have to migrate to V3 API to make use of 64-bit pointers on

OpenVMS.

1.1.2 Problems Fixed

This section describes the following problem ﬁxed in this release.

• QUIX QXCM1000928829/ WFM 2607634652, RTR loops in the listener socket

(OpenVMS only)

RTR constantly logs the "accept" error message in its log ﬁle leading to the

high utilization of the CPU by the ACP process.

RTR has a dedicated socket in the listen mode that is polled at regular

intervals to process the incoming peer node connect requests. In a rare

occurrence of a false connect notiﬁcation, RTR tries to accept the connection,

resulting in its failure. As a result, RTR loops in the listener socket and logs

the "accept" error message in the RTR log ﬁle which amounts to high CPU

utilization.

This problem is corrected in this release.
