Before you install DB2 Connect™ server products on AIX® operating
systems, ensure that the system you choose meets the necessary operating
system, hardware, software, and communications requirements.
For the most up-to-date installation requirements for DB2 Connect products, see System requirements for IBM® DB2 Connect. This
techdoc uses IBM Software
Product Compatibility Reports (SPCR). With the SPCR tool, you
can locate and find complete lists of supported operating systems,
system requirements, prerequisites, and optional supported software
for DB2 Connect products.
In
addition to system requirements, installing a
DB2 Connect product
has these additional considerations.
- Software requirements
-
- Communication requirements
- When using a communication protocol, you have the following requirements:
- For TCP/IP connectivity, no additional software is required.
- For LDAP (Lightweight Directory Access Protocol) support, you
require an IBM SecureWay Directory
Client V3.2.1 or later.
DB2 product
installation on NFS (Network File System)
The installation
of DB2® products on NFS (Network
File System) is not recommended. Running DB2 products on NFS (for example, NFS mounting
/opt/IBM/db2/V10.5 and
then running off code that was physically installed on a remote system)
requires several manual setup steps. There are also a number of potential
issues with setting up NFS for a DB2 server.
These include possible problems that involve:
- Performance (impacted by network performance)
- Availability (you are allowing a single point of failure)
- Licensing (there is no checking done across machines)
- Diagnosing NFS errors can be difficult
As mentioned, the setup for NFS will require several manual
actions including:
- Ensuring that the mount point preserve the install path
- Permission must be controlled (for example, write permission should
not be given to the mounting machine)
- DB2 registries
have to be set up manually and maintained across all mounting machines
- The db2ls command, which lists installed DB2 products and features, must
be set up and maintained properly if you need to detect DB2 products and features
- More care is required when updating your DB2 product environment
- More steps are required when cleaning up on the exporting machine
and the mounting machine
