    Cannot set MySQL as DefaultDS over a Named Pipe on Win XP

    Jose Alvarez de Lara Novice


      These are my configurations,

      MySQL - my.ini

      # MySQL Server Instance Configuration File
      # ----------------------------------------------------------------------
      # Generated by the MySQL Server Instance Configuration Wizard
      # Installation Instructions
      # ----------------------------------------------------------------------
      # On Linux you can copy this file to /etc/my.cnf to set global options,
      # mysql-data-dir/my.cnf to set server-specific options
      # (@localstatedir@ for this installation) or to
      # ~/.my.cnf to set user-specific options.
      # On Windows you should keep this file in the installation directory
      # of your server (e.g. C:\Program Files\MySQL\MySQL Server X.Y). To
      # make sure the server reads the config file use the startup option
      # "--defaults-file".
      # To run run the server from the command line, execute this in a
      # command line shell, e.g.
      # mysqld --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
      # To install the server as a Windows service manually, execute this in a
      # command line shell, e.g.
      # mysqld --install MySQLXY --defaults-file="C:\Program Files\MySQL\MySQL Server X.Y\my.ini"
      # And then execute this in a command line shell to start the server, e.g.
      # net start MySQLXY
      # Guildlines for editing this file
      # ----------------------------------------------------------------------
      # In this file, you can use all long options that the program supports.
      # If you want to know the options a program supports, start the program
      # with the "--help" option.
      # More detailed information about the individual options can also be
      # found in the manual.
      # ----------------------------------------------------------------------
      # The following options will be read by MySQL client applications.
      # Note that only client applications shipped by MySQL are guaranteed
      # to read this section. If you want your own MySQL client program to
      # honor these values, you need to specify it as an option during the
      # MySQL client library initialization.
      # ----------------------------------------------------------------------
      # The following options will be read by the MySQL Server. Make sure that
      # you have installed the server correctly (see above) so it reads this
      # file.
      # The TCP/IP Port the MySQL Server will listen on
      #Path to installation directory. All paths are usually resolved relative to this.
      basedir="C:/Archivos de programa/MySQL/MySQL Server 5.0/"
      #Path to the database root
      datadir="C:/Archivos de programa/MySQL/MySQL Server 5.0/Data/"
      # The default character set that will be used when a new schema or table is
      # created and no character set is defined
      # The default storage engine that will be used when create new tables when
      # Set the SQL mode to strict
      # The maximum amount of concurrent sessions the MySQL server will
      # allow. One of these connections will be reserved for a user with
      # SUPER privileges to allow the administrator to login even if the
      # connection limit has been reached.
      # Query cache is used to cache SELECT results and later return them
      # without actual executing the same query once again. Having the query
      # cache enabled may result in significant speed improvements, if your
      # have a lot of identical queries and rarely changing tables. See the
      # "Qcache_lowmem_prunes" status variable to check if the current value
      # is high enough for your load.
      # Note: In case your tables change very often or if your queries are
      # textually different every time, the query cache may result in a
      # slowdown instead of a performance improvement.
      # The number of open tables for all threads. Increasing this value
      # increases the number of file descriptors that mysqld requires.
      # Therefore you have to make sure to set the amount of open files
      # allowed to at least 4096 in the variable "open-files-limit" in
      # section [mysqld_safe]
      # Maximum size for internal (in-memory) temporary tables. If a table
      # grows larger than this value, it is automatically converted to disk
      # based table This limitation is for a single table. There can be many
      # of them.
      # How many threads we should keep in a cache for reuse. When a client
      # disconnects, the client's threads are put in the cache if there aren't
      # more than thread_cache_size threads from before. This greatly reduces
      # the amount of thread creations needed if you have a lot of new
      # connections. (Normally this doesn't give a notable performance
      # improvement if you have a good thread implementation.)
      #*** MyISAM Specific options
      # The maximum size of the temporary file MySQL is allowed to use while
      # recreating the index (during REPAIR, ALTER TABLE or LOAD DATA INFILE.
      # If the file-size would be bigger than this, the index will be created
      # through the key cache (which is slower).
      # If the temporary file used for fast index creation would be bigger
      # than using the key cache by the amount specified here, then prefer the
      # key cache method. This is mainly used to force long character keys in
      # large tables to use the slower key cache method to create the index.
      # If the temporary file used for fast index creation would be bigger
      # than using the key cache by the amount specified here, then prefer the
      # key cache method. This is mainly used to force long character keys in
      # large tables to use the slower key cache method to create the index.
      # Size of the Key Buffer, used to cache index blocks for MyISAM tables.
      # Do not set it larger than 30% of your available memory, as some memory
      # is also required by the OS to cache rows. Even if you're not using
      # MyISAM tables, you should still set it to 8-64M as it will also be
      # used for internal temporary disk tables.
      # Size of the buffer used for doing full table scans of MyISAM tables.
      # Allocated per thread, if a full scan is needed.
      # This buffer is allocated when MySQL needs to rebuild the index in
      # REPAIR, OPTIMZE, ALTER table statements as well as in LOAD DATA INFILE
      # into an empty table. It is allocated per thread so be careful with
      # large settings.
      #*** INNODB Specific options ***
      # Use this option if you have a MySQL server with InnoDB support enabled
      # but you do not plan to use it. This will save memory and disk space
      # and speed up some things.
      # Additional memory pool that is used by InnoDB to store metadata
      # information. If InnoDB requires more memory for this purpose it will
      # start to allocate it from the OS. As this is fast enough on most
      # recent operating systems, you normally do not need to change this
      # value. SHOW INNODB STATUS will display the current amount used.
      # If set to 1, InnoDB will flush (fsync) the transaction logs to the
      # disk at each commit, which offers full ACID behavior. If you are
      # willing to compromise this safety, and you are running small
      # transactions, you may set this to 0 or 2 to reduce disk I/O to the
      # logs. Value 0 means that the log is only written to the log file and
      # the log file flushed to disk approximately once per second. Value 2
      # means the log is written to the log file at each commit, but the log
      # file is only flushed to disk approximately once per second.
      # The size of the buffer InnoDB uses for buffering log data. As soon as
      # it is full, InnoDB will have to flush it to disk. As it is flushed
      # once per second anyway, it does not make sense to have it very large
      # (even with long transactions).
      # InnoDB, unlike MyISAM, uses a buffer pool to cache both indexes and
      # row data. The bigger you set this the less disk I/O is needed to
      # access data in tables. On a dedicated database server you may set this
      # parameter up to 80% of the machine physical memory size. Do not set it
      # too large, though, because competition of the physical memory may
      # cause paging in the operating system. Note that on 32bit systems you
      # might be limited to 2-3.5G of user level memory per process, so do not
      # set it too high.
      # Size of each log file in a log group. You should set the combined size
      # of log files to about 25%-100% of your buffer pool size to avoid
      # unneeded buffer pool flush activity on log file overwrite. However,
      # note that a larger logfile size will increase the time needed for the
      # recovery process.
      # Number of threads allowed inside the InnoDB kernel. The optimal value
      # depends highly on the application, hardware as well as the OS
      # scheduler properties. A too high value may lead to thread thrashing.

      I was googling and I did not found any solution for this issue.

      Will you help?
