Problem
User launches a JAVA-based function (for example 'Company - Command Centre'). An error appears.

Cause
There are many possible causes for the 'No driver found - dbType is invalid' error.
- See separate IBM Technote #1680804 for more examples.
This Technote specifically relates to the scenario where the cause is that the file 'ccr-dbTypes.properties' has some wrong entries in there.
Example:
In one real-life customer example, the file 'ccr-dbTypes.properties' contained the following contents:
SQL_SERVER.name = MS SQLServer
SQL_SERVER.driver = com.microsoft.sql.server.jdbc.SQLServerDriver
SQL_SERVER.url = jdbc:sqlserver://servername:1433/controller
Resolving The Problem
Reset the file 'ccr-dbTypes.properties' to the default settings.
Example (Controller 10.2.1 FP4):

# User-defined database types

# Entries in this file will override the default settings of the default file
# (which is compiled into a .jar file). Only active entries in this file will
# be read - if you want to replace a JDBC driver, you only need to un-comment
# and edit the corresponding ".driver" entry - the rest will be read from the
# default file.
# The application will look for this file in two separate places:
# 1) The root folder on the classpath, typically the folder where all jar files
# reside. This is the place for modifying server settings.
# 2) The user's home directory. This may also work for server side settings,
# but is primarily intended for modifying client settings IF client is
# running a non-standard configuration with direct DB access.
# ==========
# IMPORTANT!
# ==========
# The file is shipped and installed on the server as a an empty template. When
# editing this file, remember to make a copy and keep in a safe place to avoid
# overwriting it when the system is updated.
# Notes:
# ------
# - Names, drivers and URL strings may be modified as necessary, but you cannot
# add new entries (deleted entries will assume the pre-defined default value).
# - Only valid entries will be effective; if a specified driver is not found at
# runtime, the entry is ignored.
# - You can effectively disable an entry by specifying an invalid
# (non-existent) driver.
# - When you modify settings, it might be wise to also alter the name to get
# some kind of feedback (in GUI and/or logfile) that the modified properties
# file has actually been read.
# - The URL string must match the driver, and must hold '%s' where parameters
# should be inserted. Example:
# jdbc:db2://%s%s/%s
# - Parameters fed to the URL string are (in order of appearance in the string):
# 0=hostName, e.g. "localHost" or "sstordsql"
# 1=port, .e.g. ":80"
# 2=dataBaseName, e.g. "test_alloc"
