Note: You must<\/strong> install McIDAS-X 2020.1<\/a> on the workstation before<\/strong> you install McIDAS-XCD 2020.1. Then continue with the appropriate set of instructions, as described below.<\/p>\n\n\n\n

McIDAS-XCD v. 2020.1<\/h3>\n\n\n\n

If you are installing McIDAS-XCD for the first time on the workstation, go to the McIDAS-XCD Administrator’s Guide<\/em>‘s Installing McIDAS-XCD 2020.1 for the First Time<\/a> and complete its instructions. (Use those instructions rather than those below.)<\/p>\n\n\n\n

If you are installing McIDAS-XCD Fastrack version 2020.1 on a workstation that already has a previous version of McIDAS-XCD installed, complete the steps below.<\/p>\n\n\n\n

  1. As root<\/strong><\/span>, disable the writing of binary log files associated with the database so that it is not enabled when MySQL\/MariaDB is upgraded on your McIDAS-XCD system. This is needed because MySQL\/MariaDB 8.0 and later enable binary logging by default, which fills large amounts of disk (possibly an entire file system) due to it logging millions of INSERT into file_list<\/em> entries per day. \n

    Type: \/home\/oper\/mcidas\/bin\/gribadmin disablelog<\/strong><\/strong><\/span><\/p> <\/div> \n

    When the command is finished, you should see a message like that below.<\/p> \n

    \n
    \/etc\/my.cnf.d\/disable-log-bin.cnf successfully written!<\/pre> <\/td> <\/tr> <\/tbody> <\/table> <\/div> \n<\/div>\n
    Once its successful completion is verified, exit from root<\/strong>.<\/p><\/li>\n
  2. At a Unix prompt as user oper<\/strong>, stop McIDAS-XCD and then LDM by running the commands below in order. \n
     
    Type: xcdadmin stop<\/strong><\/span>\n
    Type: ldmadmin stop<\/strong><\/span><\/p> <\/div> <\/li>\n
  3. As user oper<\/strong><\/span>, run the script below from the ~oper\/mcidas<\/strong><\/span><\/span> directory to build and install McIDAS-XCD 2020.1 using the same settings for optional flags -noopt<\/strong><\/span> and -mysql<\/strong><\/span> as were used to build McIDAS-X 2020.1. You must use the same compilers and optional flag settings for both the McIDAS-X and McIDAS-XCD builds. \n
     
     
    Type: sh .\/xcd2020.1.sh <\/strong> <\/span>flags <\/em> build<\/strong><\/span><\/p> \n
    where flags<\/em><\/span> is zero, one or both of the two optional flags described below.<\/p> <\/div><\/div>\n
