UNIX for Dummies Questions & Answers

Hi,

Some of the process in th environment are producing a core file.
These core files are produced by default in the directory from which they were launched.
I want to change the default directory to say /tmp of that environment.

I am using both Linux and Solaris, so will need the solution for both.

Thanks in advance.

Hello Raj,

It completly depends on the services/application/tools you are using that where you want to set the default location of the logs(including core/dump logs).As you haven't mentioned which tool you are using so let's say for an example I am using JMS(Java method Server) an efficient tool for handling JAVA applications to call methods using web services or dmbasic methods. It is fairly used in content managment tools specially Documentum(A product of EMC2 very famous for content mgmt). So after installing JMS you will get the default STOP/START scripts to make service up and down in that case you have option there to mention the location of logs(any code deplyment or code/dumps too), so let's say I have given there location /tmp then it will put all logs there and if I am NOT setting anythig then it will put them in a default location $DM_HOME/bin. So check in your tool and try to expore it more about these things, share with us which tool you are using if it is not harming your company's policy. You should get many options to do so.

Hope this helps.

Thanks,

On Solaris systems, check the section 1M coreadm man page (man 1M coreadm). On Linux systems, check the section 5 core (man 5 core) and proc (man 5 proc) man pages.

In either case, the default location for a core file is the current working directory of the process at the time that it is dumping core (which might or might not be the directory in which the process started running).
