Assuming I have opened dev/poll as mDevPoll , is it safe for me to call code like this struct pollfd tmp_pfd; tmp_pfd.fd = fd; tmp_pfd.events = POLLIN; // Write pollfd to /dev/poll write(mDevPoll, &tmp_pfd, sizeof(struct pollfd)); ...simultaneously from multiple threads, or do I need to add my own synchronisation primitive around mDevPoll ? Solaris 10 claims to be POSIX compliant. The write() function is not among the handful of system interfaces that POSIX permits to be non-thread-safe , so we can conclude that that on Solaris 10, it is safe in a general sense to call write() simultaneously

Thursday, March 13, 2008 Install Solaris (SNV 84) DomU at Xen 3.2 CentOS 5.1 Dom0 (64 bit) This posting is targeting cloning Mercurial Repository for Xen 3.2 on CentOS 5.1 and creating 64-bit Xen 3.2 CentOS 5.1 Dom0. To verify Dom0 functionality Solaris (Navada Build 84) has been installed as DomU. Xvnc has been set up per Sun manuals and it appeared that only CDE Desktop was functional on DomU. Gnome Desktop crashed immediately after logging in. However , that’s quite enough to perform Oracle 10g R2 installation at DomU and evaluate I/0 performance provided by new Xen Hypervisor for Solaris

I wrote following program using namespace std; #include "hadoop/Pipes.hh" #include "hadoop/TemplateFactory.hh" #include "hadoop/StringUtils.hh" #include "libpq-fe.h" extern "C" { #include "traverser.h" } class IndexMap:public HadoopPipes::Mapper { public: IndexMap(HadoopPipes::TaskContext & context) { } void map(HadoopPipes::MapContext & context) { std::vector<std::string> paths = HadoopUtils::splitString(context.getInputValue(), "rn"); unsigned int k = 4; unsigned int l = 0; string concatpaths[k]; if (paths.size() % k == 0) { for (unsigned int i = 0; i < k; ++i) { concatpaths[i] = paths[l]; l

I have below data named atp.csv file Date_Time,M_ID,N_ID,Status,Desc,AMount,Type 2015-01-05 00:00:00 076,1941321748,BD9010423590206,200,Transaction Successful,2000,PRETOP 2015-01-05 00:00:00 077,1941323504,BD9010423590207,351,Transaction Successful,5000,PRETOP 2015-01-05 00:00:00 078,1941321743,BD9010423590205,200,Transaction Successful,1500,PRETOP 2015-01-05 00:00:00 391,1941323498,BD9010500000003,200,Transaction Successful,1000,PRETOP i want to count status wise using below command. cat atp.csv|awk -F',' '{print $4}'|sort|uniq -c The output is like below: 3 200 1 351 But i want to like below

I'm looking for a programmatic interface to the Solaris ifconfig(1M) command. Apparently Linux has the getifaddrs(3) command, but as far as I can tell this has not been ported to Solaris . Short of attempting to use the code at the link above , is there any way to determine ifconfig(1M) -type data (network interface presence, state, etc.) without forking the system command and parsing the output ? I have an implementation here, IPv4-only based on SIOCGIFCONF ioctl() 's and IP family agnostic version using SIOCGLIFCONF : http://code.google.com/p/openpgm/source/browse/trunk/openpgm/pgm

This maybe too localized, but I am hoping someone can help me articulate my questions properly. So, we have a front end web server that communicates with a back end app server using CORBA. I have been asked to port the back end application to a LINUX box, which I did. But, in order to test it, I am trying to point the front end web server to the LINUX back end. We are using omniORB-4.1.4, and here is how the instance of the back end system is obtained: String args[] = new String[0]; System.out.println(getDateTime()+"Instance: Connecting to: "+initialHost+" "+initialPort+" "+enviornment+" "
