Next week: SPC 2011 - Sydney
Developers will descend Down Under to learn about the latest in Synergy/DE
SPC 2011 will conclude its three-city tour next week in Sydney Australia. Like those in Chicago, IL and York, UK earlier this year, attendees will get the chance to work hands-on with the latest features in Synergy/DE. Comprehensive sessions and numerous hands-on workshops will provide significant new skills in Synergy/DE and other aspects of the computer industry, enabling attendees to immediately extend their applications with the latest technology. For more information about the conference, visit http://spc.synergex.com.
Free downloads for Synergy developers
RemoteServer enables you to compile remotely on UNIX and OpenVMS systems with Workbench
You may already know that you can use Workbench for UNIX and OpenVMS development. Workbench includes built-in FTP functionality for this, and you can use NFS mapped drives. (See the “Developing Your Application in Workbench” chapter of Getting Started with Synergy/DE.) With NFS mapped drives, you can even use projects and Composer with remote files. But did you know that you can use Workbench to compile remotely on UNIX and OpenVMS systems? The RemoteServer CodeExchange entry has code that enables you to do this. With RemoteServer you can set an environment variable remotely when a project is opened, and you can issue native OS commands, Synergy compiler and linker commands, library creation commands (dblibr or LIBRARIAN), and more. Note that RemoteServer works only with commands that can be executed through an opened pipe in Synergy. For more information and the code, see CodeExchange.
CodeExchange is available in the Synergy/DE Resource Center to supported Synergy/DE customers. Be sure to take advantage of this great resource, and don't forget to submit your own CodeExchange entries so that other Synergy developers can benefit from your cool code.
Data corruption using xfServer over a VPN
Using xfServer over a VPN may cause data corruption. If you experience this problem, the first thing to try is removing the VPN from the equation and testing locally using xfServer: Does any data corruption occur performing the same I/O functions? If not, then the problem is related to the VPN.
We support a TCP/IP connection and expect the TCP/IP stack to guarantee reliable delivery of data through its own cyclical redundancy checking and retry mechanisms. When using a VPN, the VPN tunnel software is in charge of delivering valid data from one end to the other. xfServer reports any TCP/IP errors reported to it, but if the VPN software is corrupting the data, xfServer would have no way of determining this and reporting it. We recommend checking the logs on the VPN encryption devices at either end of the tunnel for errors reported there. In addition, a network engineer may want to perform a large packet throughput test on the VPN tunnel.
We don't recommend using xfServer over a VPN: Its performance and characteristics are not designed for high latency, low bandwidth (and usually unreliable) links. However, as long as the VPN link works reliably, there should be no problem, although you will likely experience slower performance. If you are using a VPN, we recommend the use of the ISUTL utility to verify the integrity of the ISAM data.
Synergy/DE pros, see if you can answer this question!
What is the output of the following program?
main
record
seed1 ,int
seed2 ,int
num ,int
proc
open(1,o,"TT:")
xcall randm(num, seed1, seed2)
if (num .lt. 13768) then
writes(1, "eenie")
else
writes(1, "meenie")
end
a. "eenie" 100% of the time.
b. "meenie" 100% of the time.
c. "eenie" 50% of the time, "meenie" 50% of the time, approximately.
d. "eenie" 6.4% of the time, "meenie" 93.6% of the time, approximately.
