Re: problem with shared memory connections

many thanks for suggestions made ( Art and others ) unfortunately... it hasn't made a lot of difference. I added these lines to the config: NETTYPE ipcshm,1,50,CPU NETTYPE soctcp,1,50,NET It seems that once I get to 24 shm connections then no more are allowed, although soc connections are fine. I can't find what might be limiting this. BTW what's the easiest way to determine if a connection is shm or soc? Our default is shm ( set by $ONCONFIG) Also, the summary line for onstat -u gives "25 maximum concurrent", which seems to be a limit for shm connections, but not for soc - it simply increases for each new soc connection made. What is the significance of this value? any (more) ideas/suggestions? Unix is HP 10.20, Informix is 7.24.UC3 ( we had installed it before the tech alert on ontape, but I think this problem was with us before we went to this version ) thanks again Pete Pete Smith wrote: > hi all > > I'm having constant problems with shm connections in UDS 7.2x > The error returned is > -25588 - the appl process cannot connect to Online server server-name. > It looks like Informix will allow so many shm connections before > refusing a connection, but this seems to vary. > If I change INFORMIXSERVER to a soc connection then everything is fine, > but slower on a socket connection. > > Is there a config parameter or something that I should be looking for? > > any help or clues? > > I can supply the onconfig file if this will help > > many thanks > > Pete
