Digipass Plug-In for SBR Administrator Reference ODBC Database 3.7.3 Connection Wait Time When the SBR Plug-In already has the maximum number of connections open and a new authentication request arrives, it will wait a configurable amount of time for a connection to become available (unless the Enable Load Sharing option is used, see below). You may want to reduce this waiting time, to reduce the impact of an overload of requests. Alternatively you may want to increase the waiting time, to make it less likely that a request will be rejected due to a temporary 'spike' of requests. 3.7.4 Idle Timeout After a period of peak load, there may be a large number of connections open to the database. The Idle Timeout setting can be used to configure how quickly the connections are closed after being idle for a period of time. It may reduce the load on the database to close these connections quickly. Alternatively, if the load is very irregular but is often high, you may prefer to keep idle connections open for longer. 3.7.5 Enable Load Sharing A simple form of load sharing can be implemented if you make a second database available to the SBR Plug-In. In fact, any number of databases can be added to the list of data sources, and the load can be shared across all of them. If you have more than one database available and the Enable Load Sharing option is used, the SBR Plug-In will open connections to the second database when it would exceed the maximum number of connections it is allowed to have to the first database. Similarly, it will open connections to the third database when it has reached the maximum for the second, and so on. In general, connections to the first database will be used when available, in preference to connections to any other database. 3.7.6 Reconnect Intervals After the first data source has become unavailable, the SBR Plug-In will attempt at intervals to reconnect, even if it has successfully failed over to a second data source. It will always use the first data source in preference to the others. The Min. Reconnect Interval and Max. Reconnect Interval settings control the minimum and maximum intervals between retries respectively. The interval will start at the minimum and increase in steps until the maximum is reached. After that, the interval will stay at the maximum. © 2006 VASCO Data Security Inc. 54
Digipass Plug-In for SBR Administrator Reference ODBC Database 3.8 DPDBadmin 3.8.1 Modify Database Schema The addschema command is used to create all required tables in an existing database, if they are not already there. Each table will be checked individually to see if it is already there and if not, will be added. This command is intended to be run manually by an administrator before Digipass Plug-In for SBR is installed. It may be necessary to go through an approval process in your company before running this command. You may also need to have a database administrator run the command for you. This depends on your company’s structure and rules for control of the database. This command may also be used to create the tables required for auditing to an ODBC database. Prerequisite Information Database Administrator Account In order to successfully modify the database structure, you will need the username and password of a database administrator account that is able to make changes to the database schema – for example, creating tables. You must pass these credentials to the command in the parameters. Database Name You will need the ODBC Data Source Name of the database (as registered with Windows an as ODBC Data Source). Modify the Database Structure 1. Open a command prompt and navigate to the installation’s bin directory by typing: 2. Type: cd \bin dpdbadmin addschema –u user_name –p password -d dsn 3. See below for more details regarding the required parameters. The progress and success/failure of the command will be displayed in the command prompt window. If there was a failure, it can be run again after the problem has been rectified. Command Line Syntax dpdbadmin addschema –u user_name [–p password] -d dsn [-nouser] [-domain domain_name] [-case case_conversion] [-vdsuser alternatename] [-vdsuserattr alternatename] [-vdsdomain alternatename] [-vdscontrol alternatename] [-vdsdigipass alternatename] [-vdsdpapplication alternatename] [-vdspolicy alternatename] [vdsbackend alternatename] [-vdscomponent alternatename] [-vdsorgunit alternatename] [-audit] [-noserver] [-utf8factor factor] [-q] Table 24: DPDBadmin addschema Command Line Options © 2006 VASCO Data Security Inc. 55
