Recently, a post asked how to create an Actian / Pervasive PSQL database from the command line. PSQL on Linux has the DBMAINT utility but no such utility exists on Windows. I put some code together in C# that will create a database based specified parameters. The DTO Library will need to be added as a COM reference to the project. This is basic code but can be used as a basis for your own program. The code is:

using System;
using DTOLib;

namespace dtoTest
{
    class Class1
    {
        [STAThread]
        static void Main(string[] args)
        {
            //Code to create an Actian / Pervasive PSQL database using DTO.  
            //Code written by Michael Beris
            string compName = null;
            string userName = null;
            string password = null;
            string dbname = null;
            string ddflocation = null;
            string datalocation = null;
            dtoDbFlags dbflags = DTOLib.dtoDbFlags.dtoDbFlagDefault;

            DTOLib.dtoResult result;
            if (args.LongLength < 1)
            {
                Console.WriteLine("Invalid options.\n");
                Console.WriteLine("Usage: dtoDBN.EXE <computername> <username> <password> <dbname> <ddf location> <data location> <DBFlage>");
                Console.WriteLine("NOTE: locations must be relative to the computer where the PSQL engine is running.");
                Console.WriteLine("DB Flags must be passed as integer in this example with these values:  ");
                Console.WriteLine(" P_DBFLAG_BOUND =  1;  (* bound database - must have P_DBFLAG_CREATE_DDF too *)");
                Console.WriteLine(" P_DBFLAG_RI = 2; (*relational integrity *)");
                Console.WriteLine(" P_DBFLAG_CREATE_DDF = 4; (*create ddf flag *)");
                Console.WriteLine(" P_DBFLAG_NA = 2147483648; (*not applicable *)");
                Console.WriteLine(" P_DBFLAG_DEFAULT = (P_DBFLAG_BOUND or P_DBFLAG_RI); ");
          
                return;
            }
            if (args.LongLength == 7)
            {
                compName = args[0].ToString();
                userName = args[1].ToString();
                password = args[2].ToString();
                dbname = args[3].ToString();
                ddflocation = args[4].ToString();
                datalocation = args[5].ToString();
                dbflags = (dtoDbFlags)Convert.ToInt32(args[6]);
            }
            Console.WriteLine("Create Pervasive Database using DTO and C#");
            DtoSession mDtoSession = new DTOLib.DtoSession();
            try
            {
                result = mDtoSession.Connect(compName, userName, password);
                if (result != 0)
                {
                    Console.WriteLine("Error connecting to server.  Error code:");
                }
                else
                {
                    //Create a Database name here.  
                    DtoDatabase db = new DtoDatabase();
                    db.Name = dbname;
                    db.DdfPath = ddflocation;
                    db.DataPath = datalocation;
                    db.Flags = dbflags;
                    result = mDtoSession.Databases.Add(db);
                    if (result !=0)
                    {
                        Console.WriteLine(string.Format("Error creating the datbase ({0}).  Error code: {1}", dbname, result.ToString()));
                    }
                    else
                    {
                        Console.WriteLine(string.Format("Database ({0}) created. ", dbname));

                    }

                    result = mDtoSession.Disconnect();
                    Console.ReadLine();
                }
            }
            catch (Exception e1)
            {
                Console.WriteLine(e1.Message.ToString());
            }
        }
    }
}

We will be undergoing regular maintenance starting Saturday, December 16, 2017. The site may be intermittently unavailable until Monday, December 18, 2017. We are preparing to move hosts.

Note: Maintenance has been completed, but we are having small technical issues. They should be resolved soon.

Update: All technical issues have been resolved.
