Once you have collected your information, you can begin Problem Determination through the product Support web page, or simply submit the diagnostic information to IBM support.LanScan Pro is a simple and efficient IPv4 network scanner that discovers all active devices on any subnet: the local one, or any public subnet that you configure. LanScan is a free, simple and effective Mac OS X. Uploading the file can be accomplished using any of the methods described in the "Submitting information to IBM Support section".įor additional information on ifxcollect see the following link: The format of the file is ifxcollect.tar. $INFORMIXDIR/bin/ifxcollect -c connection -s hangĮxecuting ifxcollect will create a tar file in $INFORMIXDIR/isa/data that can be uploaded to IBM for review. To gather the information execute the following command while experiencing the connection hang: In versions of the Informix Server engine 11.70.xC1 and above ifxcollect can be used to gather diagnostic information. On Windows, collect the exported configuration from setnet32.Ĭollecting data for diagnosing connection hangs on versions 11.70.xC1 and above If the variable is not defined, the file is located at $INFORMIXDIR/etc/sqlhosts On UNIX or Linux, also collect the sqlhosts file used (pointed by the variable $INFORMIXSQLHOSTS. Any assertion failure files generated by the instance around the time when the problem started.The instance log file ( the location of which is MSGPATH value in the instance configuration file).open the informix utility setnet32 and use the button "Save to file." to export the configurationįiles to collect for versions prior to 11.70.xC1.On Windows, run these additional commands: HP-UX : ifconfig interface_name to run for each interface in the list returned by lanscan -i.Note: The ifconfig command is OS dependent and is different for some UNIX systems, such as: ifconfig (to get the IP addresses linked to the machine).On UNIX or Linux, run these additional commands: Advanced LAN Scanner is a nice, free Windows software, that is part of the category Networking software with subcategory Analysis (more specifically Monitoring) and has been published by Radmin. netstat -a and netstat -na to see all the network connections at system level both as names and numbers. Scan your network and get information about ports and PCs.One thing to look out for is the MSC VP running all the time, usually a DNS issue. Get "onstat -g act", then gather stack traces for the running threads with "kill -7 " or "onmode -X s ".onstat -g stk all ,to be run twice, 10 seconds apart.Might need "onstat -g all" ran in the same manner as above.onstat -a ,to be run twice, 10 seconds apart, to get a detailed view of the instance and of what changes with time.Processes to run for versions prior to 11.70.xC1 Does the system show other symptoms like:.Der Xirrus Wi-Fi Inspector ist eine komplette Suite von WLAN-Analyse-Tools, deren Fokus vor allem auf der Echtzeitüberwachung von Drahtlosnetzwerken und der Performance-Optimierung liegt.

Added/modified configuration of routers or firewalls. für Einsteiger relativ schwer zu bedienen.If it affects tcp connections, did you change anything in the network, in particular DNS configuration such as:. All instances present on the machine or just some ?.All types of connections or just some (shared memory, tcp/ip, pipes).Already established connections, new connection attempts or both types?.Only remote connections or local connections as well ?.Did you change the authentication method (e.g.: enabled LDAP, used a custom PAM service)?.Do client applications just hang or some returned an error code/message after a certain amount of time? List any error or warning message reported at the time on the system console or the operating system logs.General Information to collect for Informix Family product problemsĬollecting data for diagnosing engine hangs on versions prior to 11.70.xC1 For IBM® Informix® products, gather the following information for any problem:
