  • Snitz import for dummies (MS-SQL or MS-Access)

    Yes I'm a dummy, and yes, I've gone through two hellish weeks trying to migrate from Snitz to vBulletin.

    A lot of reading, consulting, and trial-and-errors have led to a smooth migration from the old forum to the new one. I'll be happy to share this knowledge with other stragglers.

    Please post your questions here and I'll gradually enrich this post with answers as we go along.

    Last but not least, thank you Steve (Impex developer) and Jerry (Snitz import developer) for your continuous support.

    Important: Impex for tier-1 forums (such as Snitz) requires both old and new databases to reside on the same physical server (I assume that this is due to transaction management and locking strategy). Fat chance one can get an MS-SQL and MySQL databases on the same server, not to speak of shared hosting.

    Hence, I decided to go for MySQL to MySQL import and dump my MS-Access or MS-SQL database to a temporary MySQL database that I set up just for this purpose.

    Then, I used a converter that I purchased from Intelligent Converters in order to create the dump file. (Dumping the Microsoft's Enterprise Manager won't help a bit because they script the dump to be read only by other MS database).

      The process is described in great details in the online manual, so there's no real need to repeat it here.

      Please ask about specific deliberations or challenges that you are facing, and keep the cheer . Today I performed my final run and it took less than 15 minutes from start to end without any obstacles.

      I'll gladly help you, just be specific
      Cheers to all,

        Not at all, this is due to databases not allowing in most cases remote access.

        If both databases allow remote access, you can have the source on one server, ImpEx on a second and vBulletin and its database on a 3rd.
        I wrote ImpEx.

          Currently giving a Snitz->Vbulletin conversion a shot and I'm facing a problem with the import.

          I've made sure the Snitz mssql database can be accessed from the new vbulletin server on the default 1433 port (I can telnet) and have activated php_mssql in WAMPS but the Impex gives me many errors in step 1 :"Check and update database" starting at:

          "ACTIVE_USERS NOT found.
          ALBUM NOT found.
          ALBUM_CAT NOT found.
          ALBUM_CONFIG NOT found.
          etc..."

          Is there a way I can test that php_mssql is working properly and able to connect to that remote database ? Do I need to specify the 1433 port somewhere ?

          TIA

            gpspassion, try the following PHP script:

            PHP Code:
            <? 
            $ser
            ="SERVEUR"#the name of the SQL Server
            $db="Runtime"#the name of the database
            $user="sa"#a valid username
            $pass=""#a password for the username

            # one line
            $conn=odbc_connect("Driver={SQL Server};Server=".$ser.";Database=".$db,$user,$pass);
            # one line

            ?>

              And this one:

              PHP Code:
              <? 
              $conn
              =mssql_connect("SERVEUR","sa",'password'); 
              if (
              $conn) { 
              echo 
              "GOOD"

              else { 
              echo 
              "BAD".mssql_get_last_message(); 


              ?>

                Thanks, worked a charm (added <?php at the beginning), so it seems my setup is correct, wonder why impex errors out then.

                [EDIT] - second one doesn't though, it seems it's missing the database name ?

                Might try the MSSQL->MYSQL route with this converter http://www.kofler.cc/mysql/mssql2mysql.html#guiversion and the import into MySQL on the vbulleting server.

                  The're also some interesting tips about debugging connection problems to MSSQL server from php.

                  Seems like the version of ntwdblib.dll file do matter.

                    Thanks, looks like the connection is ok based on your sricpt.

                    So I tried to import a 732MB .sql in MySql and naturally it was too large so I bumped up the limits to 1000MB, but now I am getting time-outs, and the data is not getting imported correctly...don't know if the limit can be raised with shlomot must have figured that out, hopefully he is still around !

                    One problem after the other, eh ! sigh...

                      How you import the dump in MySQL? Via console or phpMyAdmin? Big dumps should be imported via the mysql console.

                        Yes, being rather new at this I was using phpMyAdmin, not sure what the syntax in the mysql console should be, will try to look it up.

                            Thanks had just found this mysql -u username databasename < filename.txt but it seemed to be missing handles, yours looks better, let me drop what got imported so far and try that.

                              No luck so far, it is complaining about the syntax, maybe the path to the file. Ok, I was trying to type that from the console, duh, couldn't work, let me try from the DOS prompt, can it be done directly in the console?

                              UPDATE - it's crunching...

                              This script looked promising http://www.ozerov.de/bigdump.php but I am getting "At this place the current query includes more than 300 dump lines." errors...
