    Hash Calculations

    Rookie

       

      Hello everyone,

       

       

      we are using LD 8.8 SP1 for software/os distribution and remote control.

       

       

      When distributing software I got problems with the hash calculations. It seems it does them by random. Same task, started it he calculated hashes for NET 1.1 but not for the other, then stopped tasked and started again, task calculated hash for the other package but not for NET 1.1. So when does hash calculation takes places? Those packages were already deployed!

       

       

      Second issue is the time for hash calculation, for .NET 1.1 it takes 1 hour and 30 minutes! Is this normal? On both servers (LD and SQL) there are enough resources free.

       

       

      Any ideas on this topic would be appreatiated.

       

       

      Thanks.

          Can't answer the first question but can have a stab at the second.  A hash calculation can be quite time consuming since it has to examine the file and generate a unique number that will ensure that a modified file will not be recognised as the original.  Since it appears you have extracted all of the .net framework into its individual files, there are lot of files to check whereas if you simply distributed the original .exe there would only be one file to check.  I've always found it better to use the packed original since there is little real benefit in extracting the files first and it will often make the whole distribution process much slower.

            It only needs to calculate the hashes the first time you push out a package. It has to read the entire contents of each file, and create a hash for it. On small files like .net 1.1, it should take more than a couple minutes. Go into the console, right click on the package, and choose reset package hash. That will force it to re calculate. More than an hour is very unusual. I would delete the files, and re-copy them.

              Hi,

               

              I've just upgraded to 8.8 SP1 and experiencing the same problem, taking a very long time to Hash files!!!

              Do you find a solution to your problem?

               

              Regards
