connection timeouts

I am using apache directory studio 1.5.2
There is a very annoing issue with connections. If I leave connection open
for a long time open it gots frozen and it takes a long time to revive it.

Maybe it is possible to add some feature to connection properties like
"keepAlive" or something so that it is alway very quick to respond.

You have some info about it here :

http://directory.apache.org/community%26resources/contribute.html

But basically, it's simple : see what are the open issues in JIRA, pick 
one you think you can fix, propose a patch through JIRA. This is the 
very first step.

Don't be afraid by the code base size, there are many periferical issues 
that don't need a deep knowledge about the code base.

Improving the doco is also a way to get involved :)

Could you create a JIRA (improvement) for that request ?

Hi,

Connection stays open for half an hour.

After I am back and i want to browse the tree it freezes for some time ~30
seconds.

I would like to avoid this freeze.

I would like to have a setting on connections "edit properties"
screen.itcould be a field for ldif statement and a field for time in
seconds to fire
that ldif periodically to keep connection alive.

Aurimas

Hi Aurimas,

Could you be a little more precise?

How long the connection stays opened, "a long time" is pretty vague.
10 minutes, 10 hours, 10 days?

Same thing for the "revive time".
Are talking about milliseconds, seconds, minutes?

Thanks,
Pierre-Arnaud

i think that some ping like simple search or some periodical ldif specified
by user could be a good thing it could be not mandatory and left for users
own risk, but it could help me and others a lot.

Plain normal.

sadly, there is nothing such as a 'keep-alive' request in LDAP. We could 
send a search for the rootDSE periodically, but frankly, considering 
that LDAP is a connected protocol, that means we will potentially have 
thousands of requests sent to the server just to deal with this problem. 
Not sure it worth the effort... (IMHO, of course)
