In the LASR server you can set a memory limit, and a new SASApp will allow you to set a complete set of options.</P> Fri, 11 Mar 2016 15:54:22 GMT https://communities.sas.com/t5/Administration-and-Deployment/Limit-resources-per-User-Session/m-p/256148#M4472 JuanS_OCS 2016-03-11T15:54:22Z https://communities.sas.com/t5/Administration-and-Deployment/Limit-resources-per-User-Session/m-p/256154#M4473 <P>Hello,</P><P>&nbsp;</P><P>Sorry, i'm using Redhat Linux 6.7.</P><P>&nbsp;</P><P>Thanks for the suggestion.</P><P>&nbsp;</P><P>Best Regards,</P> Fri, 11 Mar 2016 16:07:57 GMT https://communities.sas.com/t5/Administration-and-Deployment/Limit-resources-per-User-Session/m-p/256154#M4473 andreffonseca 2016-03-11T16:07:57Z https://communities.sas.com/t5/Administration-and-Deployment/Limit-resources-per-User-Session/m-p/256155#M4474 <P>About operating system resources, ultimit is most probably your friend.</P><P><A href="http://www.tldp.org/LDP/solrhe/Securing-Optimizing-Linux-RH-Edition-v1.3/chap5sec44.html" target="_blank">http://www.tldp.org/LDP/solrhe/Securing-Optimizing-Linux-RH-Edition-v1.3/chap5sec44.html</A></P><P><A href="http://www.serverwatch.com/server-tutorials/set-user-limits-with-pamlimits-and-limits.conf.html" target="_blank">http://www.serverwatch.com/server-tutorials/set-user-limits-with-pamlimits-and-limits.conf.html</A></P><P><A href="http://unix.stackexchange.com/questions/8945/how-can-i-increase-open-files-limit-for-all-processes" target="_blank">http://unix.stackexchange.com/questions/8945/how-can-i-increase-open-files-limit-for-all-processes</A></P><P><A href="https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Resource_Management_Guide/sec-cpu_and_memory-use_case.html" target="_blank">https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Resource_Management_Guide/sec-cpu_and_memory-use_case.html</A></P><P><A href="https://access.redhat.com/solutions/30316" target="_blank">https://access.redhat.com/solutions/30316</A></P><P>&nbsp;</P><P>&nbsp;</P><P>But be careful to not intefiere with the pre-requisites of SAS VA to work, there are some important settings to not be modified:</P><P><A href="https://support.sas.com/resources/thirdpartysupport/v94/appservers/preinstall.html" target="_blank">https://support.sas.com/resources/thirdpartysupport/v94/appservers/preinstall.html</A></P><P><A href="https://support.sas.com/documentation/cdl/en/appsrvtuning/68923/PDF/default/appsrvtuning.pdf" target="_blank">https://support.sas.com/documentation/cdl/en/appsrvtuning/68923/PDF/default/appsrvtuning.pdf</A></P><P><A href="http://support.sas.com/kb/38/040.html" target="_blank">http://support.sas.com/kb/38/040.html</A></P><P>&nbsp;</P> Fri, 11 Mar 2016 16:19:50 GMT https://communities.sas.com/t5/Administration-and-Deployment/Limit-resources-per-User-Session/m-p/256155#M4474 JuanS_OCS 2016-03-11T16:19:50Z https://communities.sas.com/t5/Administration-and-Deployment/Limit-resources-per-User-Session/m-p/256157#M4475 <P>PS.
