CA ERwin Model Manager Implementation Guide

How to Prepare Your DBMS EnvironmentMicrosoft SQL Server 2005 PermissionsFor SQL Server 2000, you only need the public permission assigned to save tothe mart. However, when the repository is on an SQL Server 2005 instance,you must have the bulkadmin permission designated as well. The ability to dobulk inserts (which was permitted by the public permission, previously) is nolonger part of the public permission. As the administrator, you must explicitlydefine this permission or when you attempt to save a model to a new martcreated using a SQL Server 2005 database, an error "You do not havepermission to use the bulk load statement." is returned.Tasks to Create a Sybase DBMSThe following tasks must be performed by the DBA and system administratorresponsible for installing the software on a Sybase database managementsystem. Information provided in this section includes installation and Sybaseconnectivity software requirements.1. Use a graphical user interface (GUI) tool, ISQL (all versions), SQLAdministrator, Sybase Central Java, or Enterprise Manager to create theCA ERwin MM database. If a GUI tool is not available, you can use ISQL totype in the appropriate commands manually.Your database should meet the following criteria:■■The size of the data device you create determines the size of thedatabase. The minimum database size is 32 MB so there has to be atleast one device that is 32 MB. You should also locate the data deviceon a different disk (and disk controller) than the transaction log.For optimum performance, ensure that separate devices are used tostore the data and the transaction log. For example, you can increaseperformance by creating a 50 MB data device and a 25 MB log device.A minimum of 40 MB of disk space (data and log) is required.2. Add users.For users to access the mart you must either add existing logins as usersto the database or create new logins and add them as users of thedatabase. A login is an entity permitted to connect to the database server;a user gives a login the right to use a particular database. If you useWindows user names and passwords to secure database access (WindowsAuthentication), you must add the Windows users to your DBMS.Chapter 2: Installation and Configuration 19
