Create an Apache Derby database for the UDDI registry

Complete this task to use an Apache Derby database as the database store for our UDDI registry. Use an embedded or network Apache Derby database, and the database store can be local or remote.

The following steps use a number of variables. Before starting, decide appropriate values to use for these variables. The variables, and suggested values, are:

arg1

The path of the SQL files. On a standard installation, the path is app_server_root/UDDIReg/databasescripts.

arg2

The path to the location where we want to install the Apache Derby database.

For example, app_server_root/profiles/profile/databases/com.ibm.uddi.

(iSeries) For example, profile_root/databases/com.ibm.uddi.

arg3

The name of the Apache Derby database. A recommended value is UDDI30, and this name is assumed throughout the UDDI information. If we use another name, substitute that name when UDDI30 is used in the UDDI information.

arg4

An optional argument. Either use the value DEFAULT, or omit this argument. Specify DEFAULT to use the database as a default UDDI node. This argument is case sensitive.

To create a remote database, refer first to the database product documentation about the relevant capabilities of the product.

You complete this task only once for each UDDI registry, as part of setting up and deploying a UDDI registry.

Tasks

1. (iSeries) Start a Qshell session. Enter the STRQSH command from the IBM i command line.

2. Create a UDDI Apache Derby database using UDDIDerbyCreate.jar. Run the following Java -jar command from the app_server_root/UDDIReg/databaseScripts directory.(Windows)

   java -Djava.ext.dirs=app_server_root/derby/lib;app_server_root/java/jre/lib/ext -jar UDDIDerbyCreate.jar 
   arg1 arg2 arg3 arg4
   

   (AIX) (Linux) (HPUX) (Solaris) (UNIX) (ZOS) (iSeries)

   java -Djava.ext.dirs=app_server_root/derby/lib:app_server_root/java/jre/lib/ext -jar UDDIDerbyCreate.jar 
   arg1 arg2 arg3 arg4
   

   If the Apache Derby database already exists, we are asked to re-create it. If we choose to re-create the database, the existing database is deleted and a new one is created in its place. If we choose not to re-create the database, the command exits and a new database is not created.

   If the application server has already accessed the existing Apache Derby database, the uddiDeploy.jacl script cannot re-create the database. Use the uddiRemove.jacl script to remove the database, as described in the topic about removing a UDDI registry node, restart the server, and run the uddiDeploy.jacl script again.

3. Ensure that the database has the correct permissions to allow WebSphere Application Server to access it. Run the following command:

   chmod -R 777 arg2/arg3
   

   where arg2 and arg3 are the path and name of the Apache Derby database, as described previously.

4. If we are using a remote database, which requires network Apache Derby, or to use network Apache Derby for other reasons, for example, to use Apache Derby with a cluster, configure the Apache Derby Network Server framework. For details, see the section about managing the Derby Network Server in the Derby Server and Administration Guide.
