BDD 2007 - Troubleshooting Database issues

BDD 2007 - Troubleshooting Database issues

(Original from Ben Hunter's blog, check more details from this link:

Common issues
The following section details common issues and recommended configurations for each.
Database Rules - Ensure that the appropriate database rules have been created. Database rules are specified using the deployment point rules tab. Configuration database rules can be created manually or using the Configure DB Wizard in the Deployment Workbench.
A typical database section should look similar to the following:
The critical components of the database section are:
SQLServer - must specify the SQL server that hosts the BDD configuration database. SQLShare – must be a valid share on the SQL server and the user account (UserID as specified in the rules) must have access rights to that share. If SMS OSD Feature Pack is used for deployment then the SMS Advanced Client installation account will require access rights rather than the user account. Netlib – there are many issues with using TCP/IP sockets based connections so ONLY USE NAMED PIPES (DBNMPNTW).Database connectivity issues – There are a number of issues that can stop the client connecting to the SQL server, these are detailed below:
Ensure that Named Pipes is enabled for remote connectivity on the SQL server, this is not enabled by default. Has the surface area been configured to enable Named Pipes? When using SQL 2005 it is important to ensure that the “Surface area” is configured in such a way that remote connectivity to Named Pipes is allowed. If you have issues accessing the database from the workbench then ensure that you are using Named Pipes. The Deployment Workbench always uses Named Pipes to connect to the database.Security - has the deployment account got the appropriate database rights? The account used will need read rights to the BDD admin database. The account can vary depending on the deployment type:
ZTI – The SMS advanced client installation account. LTI – The user account specified in the rules (bootstrap.ini).SQL instances – If you are connecting to a database instance then this instance must be specified. This value is specified using the Instance field in the deployment workbench

Troubleshooting methods
During the troubleshooting process it is critical that you can easily test the database rules. The following instructions detail how to manually test the database connectivity. The rules specified in the deployment point can be tested without running through the entire BDD build process. Rules are processed using a script called ZTIGather.wsf, this script can be run separately from the other BDD scripts allowing easy testing. The steps below detail the process required to perform manual rule testing. To properly reflect the deployment environment it is important to perform these tests from a client device:
1. Create a folder on the client device and copy the following files from the deployment point to this folder:
ZTIGather.wsf ZTIGather.xml ZTIUtility.vbs CustomSettings.ini 2. Delete C:\MININT directory if it already exists. This folder can also be located at X:\MININT if the C drive is not available.
NOTE: BDD stores configuration and progress information in the MININT folder, if this folder is not removed between tests then the results will be invalid.
3. From the command prompt navigate to the newly created folder and execute the rule processing script using the following command:
"cscript.exe ZTIGather.wsf /debug:true"
The script will then be processed and the results outputted to the command prompt and a log file ( .\MININT\SMSOSD\OSDLOGS\ZTIGather.log)
