If you succeed in running +any of the other RDBMSes, please provide feedback about any required +change either in the code or in the test scripts by means of OpenLDAP's +Issue Tracking System (http://www.openldap.org/its/). + +1) slapd must be compiled with back-sql support, i.e. configure +with --enable-sql switch. This requires an implementation of the ODBC +to be installed. + +2) The ODBC must be set up appropriately, by editing the odbc.ini file +in /etc/ (or wherever your installation puts it) and, if appropriate, +the odbcinst.ini file. Note: you can also use custom odbc.ini and +odbcinst.ini files, provided you export in ODBCINI the full path to the +odbc.ini file, and in ODBCSYSINI the directory where the odbcinst.ini +file resides. +Relevant info for our test setup is highlighted with '<===' on the right. + +2.1) PostgreSQL + +2.1.1) Add to the odbc.ini file a block of the form + +[example] <=== +Description = Example for OpenLDAP's back-sql +Driver = PostgreSQL +Trace = No +Database = example <=== +Servername = localhost +UserName = manager <=== +Password = secret <=== +Port = 5432 +;Protocol = 6.4 +ReadOnly = No +RowVersioning = No +ShowSystemTables = No +ShowOidColumn = No +FakeOidIndex = No +ConnSettings = + +2.1.2) Add to the odbcinst.ini file a block of the form + +[PostgreSQL] +Description = ODBC for PostgreSQL +Driver = /usr/lib/libodbcpsql.so +Setup = /usr/lib/libodbcpsqlS.so +FileUsage = 1 + +2.2) MySQL + +2.2.1) Add to the odbc.ini file a block of the form + +[example] <=== +Description = Example for OpenLDAP's back-sql +Driver = MySQL +Trace = No +Database = example <=== +Servername = localhost +UserName = manager <=== +Password = secret <=== +ReadOnly = No +RowVersioning = No +ShowSystemTables = No +ShowOidColumn = No +FakeOidIndex = No +ConnSettings = +SOCKET = /var/lib/mysql/mysql.sock + +2.2.2) Add to the odbcinst.ini file a block of the form + +[MySQL] +Description = ODBC for MySQL +Driver = /usr/lib/libmyodbc.so +FileUsage = 1 + +2.3) IBM db2 +[n.a.] + +3) The RDBMS must be setup; examples are provided for my installations +of PostgreSQL and MySQL, but details may change; other RDBMSes should +be configured in a similar manner, you need to find out the details by +reading their documentation. + +3.1) PostgreSQL + +3.1.1) Start the server +on RedHat: +[root@localhost]# service postgresql start +on other systems: read the docs... + +3.1.2) Create the database: +[root@localhost]# su - postgres +[postgres@localhost]$ createdb example + +3.1.3) Create the user: +[root@localhost]# su - postgres +[postgres@localhost]$ psql example +example=> create user manager with password 'secret'; +example=> + +3.1.4) Populate the database: +[root@localhost]# cd $SOURCES/servers/slapd/back-sql/rdbms_depend/pgsql/ +[root@localhost]# psql -U manager -W example +example=> +[root@localhost]# psql -U manager example < backsql_create.sql +[root@localhost]# psql -U manager example < testdb_create.sql +[root@localhost]# psql -U manager example < testdb_data.sql +[root@localhost]# psql -U manager example < testdb_metadata.sql + +3.1.5) Run the test: +[root@localhost]# cd $SOURCES/tests +[root@localhost]# SLAPD_USE_SQL=pgsql ./run sql-test000 + +3.2) MySQL + +3.2.1) Start the server +on RedHat: +[root@localhost]# service mysqld start +on other systems: read the docs... + +3.2.2) Create the database: +[root@localhost]# mysqladmin -u root -p create example +(hit for the empty password). + +3.2.3) Create the user: +[root@localhost]# mysql -u root -p example +(hit for the empty password) +mysql> grant all privileges on *.* \ + to 'manager'@'localhost' identified by 'secret' with grant option; +mysql> exit; + +3.2.4) Populate the database: +[root@localhost]# cd $SOURCES/servers/slapd/back-sql/rdbms_depend/mysql/ +[root@localhost]# mysql -u manager -p example < backsql_create.sql +[root@localhost]# mysql -u manager -p example < testdb_create.sql +[root@localhost]# mysql -u manager -p example < testdb_data.sql +[root@localhost]# mysql -u manager -p example < testdb_metadata.sql + +3.2.5) Run the test: +[root@localhost]# cd $SOURCES/tests +[root@localhost]# SLAPD_USE_SQL=mysql ./run sql-test000 + +3.3) IBM db2 +[n.a.] + +3.3.1) Start the server: + +3.3.2) Create the database: + +3.3.3) Create the user: + +3.3.4) Populate the database: +connect to the database as user manager, and execute the test files +in auto-commit mode (-c) +[root@localhost]# su - manager +[manager@localhost]$ db2 "connect to example user manager using secret" +[manager@localhost]$ db2 -ctvf backsql_create.sql +[manager@localhost]$ db2 -ctvf testdb_create.sql +[manager@localhost]$ db2 -ctvf testdb_data.sql +[manager@localhost]$ db2 -ctvf testdb_metadata.sql +[manager@localhost]$ db2 "connect reset" + +3.3.5) Run the test: +[root@localhost]# cd $SOURCES/tests +[root@localhost]# SLAPD_USE_SQL=ibmdb2 ./run sql-test000 + +4) Cleanup: +The test is basically readonly; this can be performed by all RDBMSes +(listed above). + +There is another test, sql-test900-write, which is currently enabled +only for PostgreSQL and IBM db2.
