Ensure that you meet all of the software, hardware and
operating system prerequisites before you download a fix pack.
Procedure
Before downloading a fix pack, perform the following
steps:
- Ensure that your system meets all of the installation requirements.
- Ensure that your system
meets all of the installation requirements. Refer to Installation requirements for DB2 database products.
This action prevents technical problems
that might occur after the installation and configuration of the fix
pack.
- For 64-bit DB2 for Linux on System i® and IBM® Power Systems™, ensure that
the IBM XL C/C++ Compiler run
time is installed.
Download
and install the IBM XL C/C++
Run-Time Environment Component. Refer to: http://www.ibm.com/support/docview.wss?uid=swg24007906
- For AIX®, if DB2 database products already exist
on the system and the Trusted Computing Base (TCB) is enabled, ensure
it is in a consistent state.
Ensure that the TCB is
in a consistent state for any file or directory related to a DB2 instance, the DB2 Administration Server, and installed DB2 files. The TCB can be in an
inconsistent state if, for example, DB2 instances
were removed without using the db2idrop command.
To
check the TCB state, enter the following command as root:
tcbck -n ALL
Refer
to
AIX documentation for details
regarding the Trusted Computing Base.
- Review the Flashes and open Authorized Problem Analysis
Reports (APARs) on the DB2 for Linux, UNIX and Windows product
support website: http://www.ibm.com/software/data/db2/support/db2_9/.
Open
APARs describe defects that are not yet addressed in a fix pack, and
they might contain workarounds that will impact your use of the database
system. For a list of open DB2 for Linux, UNIX and Windows APARs,
refer to: http://www.ibm.com/support
- Ensure that you have sufficient file system free space
to download and extract the fix pack.
On Linux and UNIX, you need to have a file system
with one gigabyte of free space to contain the .tar.gz file
and the uncompressed installation image. If you also plan to install
a national language fix pack, you need up to two gigabytes of free
space.
- Ensure that you have the free space required to install
the fix pack.
The free
space must be available in the location of the DB2 copy that you are updating or in the location
where you plan to create a new DB2 installation.
- On Windows, the space
required to install the fix pack is equal to the space required for
the DB2 Version 10.1 for Linux, UNIX and Windows general
availability (GA) installation. Ensure the space required is available
in the location of the DB2 copy
that you are updating or in the location where you plan to create
a new installation of DB2. Refer
to Disk and memory requirements.
- On Linux and UNIX:
- If you do not already have a DB2 database
product installed and you are using the fix pack to create a new installation,
refer to Disk and memory requirements.
- If you already have DB2 database
product installed, the space required to install the fix pack is equal
to the space consumed by the existing DB2 database
products. This space is only required temporarily during the fix
pack installation process.
To determine the space used by the existing DB2 database products, perform the
command:
du -k -s DB2DIR
where
DB2DIR represents
the location where the DB2 database
product is installed.
- If you already have a DB2 database product installed and
have obtained special fixes, contact IBM support to determine whether you need an
updated version of the fixes before you install a fix pack.
This
helps to ensure that your system is in a consistent state and that
no special fixes are lost.
- Optional: Review
the "Product overviews" in the DB2 Information Center.
Results
Once you have ensured that you meet all of these prerequisites,
complete the remainder of the necessary tasks before installing a
fix pack.
