.net - WCF and "Persistent Connections" -


i trying calls wcf services use load balancer (an f5).

the problem when try set 1 of machines in pool "disabled" still send requests through machine.

the documentation f5 says when server disabled "only persistent or active connections allowed".

i wondering if wcf using persistent connection (or similar) bypassing loadbalancer's efforts disable node on server.

(the goal disable server, active connections out, update code on server, re-enable it.)

does wcf use persistant connections default? if so, way turn off?

there no default connections in wcf (you mean - communication channels) depends explicit or implicit (via factories) hosting configurations.

the (true-)'persistent' communication provided duplex nettcpbinding (active connections). durable services allows other (business-)dimension of persistence (via http, connections not open, active). wcf sessions, reliable sessions - same story - fake 'persistence'.

so check wcf's (hosting) configuration.

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
