9 1 Introducing HP Web Jetadmin Database Connector Plug-in This chapter contains the following topics: Overview Configuring the external database Removing HP Web Jetadmin Database Connector Plug-in ENWW 9

10 Overview An increasing number of application plug-ins for HP Web Jetadmin need to share data and export and import data from external sources. Although some application plug-ins can use HP Web Jetadmin's proprietary device cache, some application plug-ins need to customize and track device data over time. Application plug-ins that track device data from a large network can rapidly accumulate gigabytes of data. These application plug-ins require a more flexible database. HP Web Jetadmin Database Connector Plug-in is an application plug-in for HP Web Jetadmin that provides an interface layer between other application plug-ins for HP Web Jetadmin and a database management system (DBMS). HP Web Jetadmin Database Connector Plug-in uses Open Database Connectivity (ODBC) to connect to a DBMS. This allows application plug-ins to share data without conflict. HP Web Jetadmin Database Connector Plug-in defaults to an internally generated Microsoft Access database. Specifically, HP Web Jetadmin Database Connector Plug-in supports the following database management systems: Microsoft Access, versions 2000 and 2002 MySQL Server, versions 3.23 and 4.0 Microsoft Desktop Engine (MSDE), versions 1.0 and 2000 Microsoft SQL Server, versions 7 and 2000 When you create and configure a new external database, HP Web Jetadmin Database Connector Plug-in creates the tables and starts collecting and storing data from devices. You can also configure HP Web Jetadmin Database Connector Plug-in to use an existing database containing data that has already been collected from devices. This means that the device data does not need to be collected again and again for every application plug-in that uses HP Web Jetadmin Database Connector Plug-in. See the HP Web Jetadmin Report Generation Plug-in Installation Guide for more information about installing HP Web Jetadmin Database Connector Plug-in. To access the Installation Guide, go to and browse to the HP Web Jetadmin Report Generation Plug-in information page. Configuring the external database Once you have installed HP Web Jetadmin Database Connector Plug-in, you must create and configure a new external database or configure an existing external database. You can configure the external database on the External Database Connector > Database Configuration page. You must use an external database that has at least 1 GB of space available Introducing HP Web Jetadmin Database Connector Plug-in ENWW

11 Configuring a Microsoft Access database You should create a new Microsoft Access database so that HP Web Jetadmin Database Connector can create the tables in the database. However, if you have HP Web Jetadmin Database Connector Plug-in already installed on another host machine and have configured a database on that host machine, you can use that database. To configure a Microsoft Access database, you must specify the full path name, including the file name, where you want to create a new database file or where an existing database files resides. The following is an example: C:\Program Files\HP Web Jetadmin\doc\plugins\hpjdb\database.mdb To optimize performance, you should store the database file on the host machine where HP Web Jetadmin is running. Configuring a MySQL Server database To configure a MySQL Server database, you must specify the following information: The name or IP address of the server where MySQL Server is installed and configured. For example, if MySQL Server is installed on a server called dbserver that has an IP address of , you can type either dbserver or The port where MySQL Server listens. The default port is The login name of a user who has rights to create a database. When MySQL Server is installed, a user name called root is created with the rights that are required. The password for the login name that you specified. When MySQL Server is installed, root has a blank password. Configuring a Microsoft Desktop Engine or Microsoft SQL Server database To configure a Microsoft Desktop Engine (MSDE) or Microsoft SQL Server database, you must specify the following information: The name or IP address of the server where MSDE or SQL Server is installed and configured. For example, if MSDE or SQL Server is installed on a server called dbserver that has an IP address of , you can type either dbserver or The port where MSDE or SQL Server listens. The default port is ENWW Configuring the external database 11

12 Removing HP Web Jetadmin Database Connector Plug-in You can only remove HP Web Jetadmin Database Connector Plug-in through HP Web Jetadmin if you have not installed an application plug-in that has a dependency on HP Web Jetadmin Database Connector Plug-in, such as HP Web Jetadmin Report Generation Plug-in. To remove the software, perform the following steps: 1 Select Product Update from the Navigation drop-down list. 2 Click Remove. 3 Select HP Web Jetadmin Database Connector Plug-in from the Installed Packages list. 4 Click Uninstall Packages. 5 If the list of packages to be removed is acceptable, click Next. The Results page indicates if HP Web Jetadmin Database Connector Plug-in was successfully removed Introducing HP Web Jetadmin Database Connector Plug-in ENWW

13 2 Comparing database management systems This chapter contains the following topics: Overview Microsoft Access MySQL Server Microsoft Desktop Engine Microsoft SQL Server ENWW 13

14 Overview This chapter provides information about the database management systems (DBMS) that HP Web Jetadmin Database Connector Plug-in supports. This information will help you select which DBMS you want to use. Microsoft Access Microsoft Access is a file-based, relational database. Microsoft Access supports fewer features than other database engines support. For more information about Microsoft Access, go to Database size Microsoft Access supports up to 2 GB per database. Scalability and limitations For performance reasons, HP recommends the following: You should have no more than 20 concurrent connections. You should create the Microsoft Access MDB file on the server where HP Web Jetadmin Database Connector Plug-in is installed. MySQL Server MySQL Server is an open source, enterprise class database server. For more information about MySQL Server, go to Microsoft Desktop Engine Microsoft Desktop Engine (MSDE) is a local 1-2 processor data engine that can be shared. MSDE is essentially a scaled-down version of, and fully compatible with, Microsoft SQL Server. For more information about MSDE, go to Comparing database management systems ENWW

15 Database size MSDE supports a database that is a maximum of 2 GB. This limitation is per database, not per server. A single server can support multiple MSDE instances, each with a database of up to 2 GB. Scalability and limitations For performance reasons, HP recommends that you have no more than five concurrent connections. If your solution must support more than five concurrent connections, HP recommends that you migrate to Microsoft SQL Server for this higher level of scalability. Microsoft SQL Server Microsoft SQL Server is an enterprise class DBMS. For more information about Microsoft SQL Server, go to ENWW Microsoft SQL Server 15
