Connection problems using IDS 7.24 on HP UX 11.00

HI, Has anyone of you experienced this by any chance. I have a client using IDS 7.24.UC8A on HP UX 11.00 and connects tow different ways: using Powerbuilder on one hand from PCs using Windows and Flowmind using JDBC on the other side on a unix box. There are 4 instances of Informix running on the HP server. The problem we are facing si only one of the nstances. The one that receives thegreatest number of connection requests. They do not have the source code to the application coming through FLowmind which resides on a separate UNIX server that acts as a client to the HP server that rund IDS 7.24. Hence we cannot change anything on the client side. For your information, the POWERBUILDER conneciotns coming from the PCs are OK. Some of the connections from Flowmind get rejected. We tried to add poll threads. That did not help. I advised to add ports and hence listen threads, but they cannot do that since they cannot change the client configuration. The online.log does not give any errors. Only the FLowmind log file says that the request was rejected. Here is what onsta gives us: we notice 165 rejected connections. -------------------------------------------------------- $ onstat -g ntd INFORMIX-OnLine Version 7.24.UC8A -- On-Line -- Up 06:40:42 -- 71672Kbytes global network information: #netscb connects read write q-free q-limits q-exceed 102/ 135 1872 1552945 1552947 35/ 35 240/ 10 0/ 0 Client Type Calls Accepted Rejected Read Write sqlexec yes 1855 165 1547279 1549138 srvinfx yes 0 0 0 0 onspace yes 0 0 0 0 onlog yes 0 0 0 0 onparam yes 0 0 0 0 oncheck yes 0 0 0 0 onload yes 0 0 0 0 onunload yes 0 0 0 0 onmonitor yes 0 0 0 0 dr_accept yes 0 0 0 0 cdraccept no 0 0 0 0 ontape yes 1 0 3689 3689 srvstat yes 16 0 16 32 asfecho yes 0 0 0 0 listener yes 0 0 1956 84 crsamexec yes 0 0 0 0 safe yes 0 0 0 0 Totals 1872 165 1552940 1552943 ------------------------------------------------------------------ Any great suggestions?

It looks like you are reach a limit of the HPUX OS which requires special handling in the kernal. I believe 7.24 was actually built on HPUX 10 and certified to run on HPUX 11. You will need to increase the max file limit per process (NOT the global file limit, but the per process file limit). I know at one time there were issues doing this through sam (HP graphical kernel config tool). You would make the change, save the change, but if you looked at /stand/system the change was not there. I believe the configuration parameter in the kernel is call maxfiles_lim Also, you will be much better offf with a nettype of the following NETTYPE soctcp,2,1500,CPU # Configure poll thread(s) for nettype John F.

Thanks John for the info. It seems that the problem went away by modifying the NETTYPE parameter to : NETTYPE soctcp,2,1000,NET I am still waiting for the client to come back to me for a definite answer about the Kernel parameters.
