b' Tango Database server README\n ============================\n \nThis file contains information on installing/upgrading the Tango database\nserver. This guide assumes that a MySQL daemon runs on the machine you\nwant to install the database and that the DB server has history capabilities\n(Release_2_9 or higher).\nNote: You need jive 3.3 or higher to be able to access history.\n\n------------------------------------------------------------------------\nStarting from scratch\n------------------------------------------------------------------------\n\n#Launch the mysql client\n\nmysql -u[user] -p[password]\n\n#Create the tango scheme, add the declaration of the DB server and\n#initialise history tables.\n\nmysql>source tango_create.sql\n\n# Set-up the environment variables MYSQL_USER and MYSQL_PASSWORD\n# or prepare the my.cnf (mysql configuration file) file to specify \n# the mysql user and its password to be used to connect to the database.\n\n# The user is root without a password\nexport MYSQL_USER=root\n\n#Now, you should be able to launch the DB server\n\nDatabaseds 2 -ORBendPoint giop:tcp:[hostname]:[port]\n\n#To test if the DB server is working fine, you can launch jive\n\nexport TANGO_HOST=[hostname]:[port]\njive\n\n\n------------------------------------------------------------------------\nHow to upgrade the DB scheme. This section descrbies what you have to do \nif you already use a DB server running with an old scheme (without history \ntables)\n------------------------------------------------------------------------\n\n#Launch the mysql client\n\nmysql -u[user] -p[password]\n\n#Check if the database scheme has already history tables\n\nmysql>show tables;\n\n#If the scheme already has history tables, you should see the 6 following \n#tables\n+--------------------------------+\n| Tables_in_tango |\n+--------------------------------+\n| ... |\n| history_ids |\n| property_attribute_class_hist |\n| property_attribute_device_hist |\n| property_class_hist |\n| property_device_hist |\n| property_hist |\n| ... |\n+--------------------------------+\n\n#Note: If your database server stops with the following exception,that means \n#that you don\'t have the correct scheme.\n\nReceived a CORBA::Exception\nTango exception\nSeverity = ERROR\nError reason = DB_SQLError\nDesc : Failed to query TANGO database (error=Table \'tango.property_device_hist\' doesn\'t exist)\nOrigin : DataBase::check_history_tables()\n\n#If you don\'t have the history scheme:\n#Use the db_init_history program to create/initialise history tables.\n#This program will create and fill the history tables with the current \n#dababase property values (to initialize the first value of the \n#property history). This tool does not affect old tables, that means \n#that even if you run this tool, you will still be able to launch\n#an old release of the DB server.\n\ndb_init_history [user] [password]\n\n#Now, you should be able to launch the DB server\n\nDatabaseds 2 -ORBendPoint giop:tcp:[hostname]:[port]\n\n#To test if the DB server is working fine, you can launch jive\n\nexport TANGO_HOST=[hostname]:[port]\njive\n\n\n------------------------------------------------------------------------\nHow to change the history depth (Number of value kept in the property history)\n------------------------------------------------------------------------\n\nYou can set the property history depth by setting the "historyDepth" device \nproperty of the DB server. The default value is 10.\nNote that you have to launch the DB server in order to be able to configure \nthis property with Jive and then to restart the DB server to take change into\naccount.\n\n\n'
