New Features and Problems Fixed
1.2 RTR Version T5.2 EFT1
This problem has been fixed in this release.
• A combination of read-write and read-only transactions processed by a strict
order shadow partition at the primary site will lead to transaction pile up
at the secondary site. The primary ACP incrementing the commit sequence
number of the read-only transactions never gets processed at the secondary
ACP. Because the criteria used to maintain the ordering of messages at
secondary ACP fails, all transactions at secondary ACP is stored in its buffer.
This problem has been fixed in this release.
• RTRACP obtains only the primary interface address when there are multiple
interfaces configured with Internet Protocol on a Linux (Integrity servers and
x86_64) system. This results in RTR reporting the LNXINETNOIP error in
its log file.
This problem has been fixed in this release.
• QUIX QXCM1000853085/WFM 1601181965-163, Front-ends prevented from
connecting because of the socket problems with RTRD
RTRD is modified to wait for a user specified time period to complete the
processed ACP port lookup or web service request. If RTRD cannot complete
the service request in the given time period, it aborts the request and
proceeds with a new service request.
This mechanism provides additional protection to RTRD, which prevents
it from blocking on a service request indefinitely. When RTRD aborts the
request due to the timeout, an error message is created in the log file.
By default, the time period to complete a service request is set to 10 seconds.
This time period (in seconds) is configurable using the logical,
RTR_RTRD_TIMOUT, which accepts the values between 1-60 seconds range.
The minimum value of the time period is 1 second and the maximum value is
60 seconds.
On OpenVMS, the user account from which RTRD process is started must
have an appropriate TQELm quota.
On a router node, the TQElm quota must be set to twice the number of
front-ends and back-ends or 2000 or whichever is higher. The TQElm quota
for a back-end node must be set to twice the number of routers or 2000 or
whichever is higher.
The TQElm quota requirement of ACP and Com-server processes remains
unchanged because of this update to RTRD. For information about starting
ACP with the appropriate command-line parameters related to process quota,
see the HP Reliable Transaction Router System Manager’s Manual.
• The
RTR SHOW PROCESS
command output is modified to display the process
name followed by the user name on HP-UX, Linux, and Windows platforms,
which is consistent with OpenVMS.
