ODBC, CLI, and .NET
The installation methods for IBM Data Server Client, IBM Data Server Runtime

these IBM clients are generally referred to as the IBM data server client.
If the system already has prior version of a client installed, migration should be

a single machine. However, the following restrictions apply for the IBM data
server client when installing multiple DB2 copies on a single system:
Non-root/Non-Administrator installations do not support multiple DB2 copies.
Multiple copies must be installed in a different path. The default directory
name for installing multiple copies of DB2 product is:
– C:\Program Files\IBM\sqllib_nn for Windows.
– /opt/ibm/db2/V9.5_xx for Linux.
– /opt/IBM/db2/V9.5_xx for AIX, HP-UX or Solaris.
Where nn is the number of copies installed in that machine minus one, and xx
is the number in the range 01 to 99.
On a Windows platform, a maximum of 16 copies of Data Server Runtime
Client and 16 copies of Data Server Driver for ODBC, CLI, and .NET can be
installed on any given system.
