The documentation states -ct has a default of 50 and a minimum of 1.
In the pkb I found that in v8 the value used to be 5 or 10.
I'd like to set the parameter as low as possible but without introducing new issues.
Are there drawbacks to setting this value to 1 ?
What are the situations in LAN in which the first connection would fail and a subsequent try to succeed ? other than somebody starting the database server in the 50 seconds it takes to retry 50 times.
networks are much more reliable now than when this was implemented in version 4. coonnections on a LAN hardly ever fail due to sporadic network dropouts or message corruption. so set it to 1 or 2. if two retries dont work, more won't either.
(in 30 years, i've never seen anyone actually use this parameter)

I didn't know the parameter existed, I was under the impression we needed to change some OS TCP/IP parameter to make connect fail faster.
I have some use cases for it.

someone in development will have to verify that this parameter actually does something. when orgiginally implemented there were a bunch of other network protocols and several flavors of tcp/ip. now only the standard tcp/ip remains.
I can confirm that -ct still does something. As mentioned above, if not set, the default is 50 tries. I'm guessing that -ct stands for "connection try", but functionally, it really is "connection retry". The AVM attempts the connection and then retries N times, where N is set via -ct.
I can also confirm that on linux using OpenEdge 11.7 with -ct 1 you get an almost instant error if the database you connect client/server is not running
Without -ct it takes almost a minute (50+ secs)
-ct 1 should go in your .pf file in the $DLC directory.
Sounds like a great candidate for a new and improved default value.
-ct in startup.pf does not work, you need to specify it for each database connection seperately

of course it doesn't (since it is a database connection parameter). i was a fool to suggest it.

C'mon Gus, you were just testing to see if people still read your posts ;-)
