NAME

OpenInteract2::Manual::AdminDatabase - Setting up databases for use with OpenInteract2

DESCRIPTION

OpenInteract2 is designed to work with one or more relational database systems (RDBMS). Thanks to SPOPS, it can be flexible about which one it uses. But you still need to do some initial setup work to ensure your database is prepared.

This document describes the different procedures necessary to use OpenInteract2 with the databases it supports. It does not cover setting up the various RDBMS packages themselves and assumes you have a database server up and running.

In the discussion below we use a few variables. These will, of course, depend on your DBMS.

  • $ADMINUSER: A user with sufficient administrative rights to create a database

  • $ADMINPASSWORD: The password for $ADMINUSER

  • $DBNAME: The name you give your database.

  • $WEBUSER: The user that is going to access this database via OpenInteract. This user must be able to create and drop tables as well as modify data within those tables.

  • $WEBPASSWORD: The password for $WEBUSER

The following also assumes that the command-line utilities executed (e.g., 'mysql', 'psql', 'isql') are installed and on your PATH. If not, setup your PATH so they're accessible for executing or ask your friendly local DBA to do this for you.

MySQL

To create a database, run the following command:

$ mysqladmin --user=$ADMINUSER --password=$ADMINPASSWORD create $DBNAME

Once the database is created, ensure that the non-administrative user you've chosen to use with OpenInteract has full access to it. The following will create a new user with access to your database:

$ mysql --user=$ADMINUSER --password=$ADMINPASSWORD $DBNAME
mysql> GRANT ALL ON $DBNAME.* TO $WEBUSER@localhost 
mysql> IDENTIFIED BY '$WEBPASSWORD'\g

You will probably also need to give this user permission to use the 'mysql' database:

mysql> GRANT SELECT ON mysql.* TO $WEBUSER@localhost 
mysql> IDENTIFIED BY '$WEBPASSWORD'\g

Once you're done with these statements, leave the mysql shell and reload the grant tables:

$ mysqladmin --user=$ADMINUSER --password=$ADMINPASSWORD reload

PostgreSQL

To create a database, run the following command as the postgres (or equivalent) user:

$ createdb $DBNAME

Once you've created the database, you can create a user:

$ psql $DBNAME
psql> create user $WEBUSER 
psql> with password '$WEBPASSWORD' nocreatedb nocreateuser\g

iAnywhere Solutions (Sybase) ASA

There are two methods for most adminstrative tasks ASA: GUI (Sybase Central) or command-line. Sybase Central offers the "ease of use" of a GUI. Command-line tools offer the ability to script commands, making administrative tasks reproducible, configurable and version controlable.

Command-line tools

To create a database file and start up an engine on that new database:

$ dbinit -p 4096 $DBNAME
$ dbsrv9 ${DBNAME}.db

Once the database is created, create the non-administrative user you've chosen to use with OpenInteract:

$ dbisql -nogui -c "UID=DBA;PWD=SQL;ENG=$DBNAME"
dba> GRANT CONNECT TO $WEBUSER IDENTIFIED BY '$WEBPASSWORD';
dba> QUIT;

Notes

  • 4096 is the recommended page size for most common database uses; 2048 is the default. See the online ASA docs for more information on the dbinit utility.

  • By default, ASA is a case-preserving database. This means that character data comparisons are case-insensitive, but that character data is stored exactly as given.

  • A database engine can be started using the Network Server (dbsrv9) or the Personal Server (dbeng9). Both programs use the same engine, but dbeng9 is limited to a maximum of 10 concurrent connections and only allows network connections from localhost. See the online ASA docs for more information on the dbeng9 and dbsrv9 commands.

  • dbisql is a GUI application by default. If running in a non-GUI environment or if you want to simply call it from a script and avoid the overhead of window creation, use the -nogui option.

  • You can call dbisql in batch mode, giving it a SQL command that will execute after which DBISQL will terminate:

    $ dbisql -nogui -c "UID=DBA;PWD=SQL;ENG=$DBNAME" my_sql_commands.sql
$ dbisql -nogui -c "UID=DBA;PWD=SQL;ENG=$DBNAME" "SELECT * FROM SYSTABLE;OUTPUT TO '/tmp/systable.out' FORMAT ASCII;"

  • It is strongly advised that you change the default DBA account password before making the database available to others:

    $ dbisql -nogui -c "UID=DBA;PWD=SQL;ENG=$DBNAME" grant connect to DBA identified by 'My New Password';

  • ASA is a full-featured SQL database engine. It is not derivative of ASE. See http://www.ianywhere.com/ for more information.
