Installation scripts are not too smart, they does not analyze free disk space accurate, therefore pls do not separate /opt, /usr, /home, /var. The resulting disk usage after clean installation and empty database will be similar:
12G /opt 1.7G /home 2.0G /usr 121M /var
/home is default location for DB2 database, this could be configured to other place after DB2 setup but before DB creating.
While you can reorganize partitioning scheme later, just assign 40G disk and assign all to root filesystem, otherwice installation script will fail.
In addition, you will need temporary space at least 12G for unpacked installation media. It could be tmpfs, just add more memory.
At least 8G RAM and 4CPU required. If you will use /tmp tmpfs for unpacking, add 12G RAM for installation time and add following line to /etc/fstab:
tmpfs /tmp tmpfs size=12g,mode=1777 0 0
Installation procedure worked on Red Hat Enterprise Linux Server release 6.7 (Santiago) x86_64 architecture
Create /src directory and transferr to it downloaded software.
Ensure that you have installed the following packages, some of them 32bit:
PackageKit-gtk-module.x86_64 binutils.x86_64 compat-libstdc++-33.i686 compat-libstdc++-33.x86_64 expat.i686 expat.x86_64 firefox.x86_64 gcc-c++.x86_64 gcc.x86_64 gtk2-engines.x86_64 kernel-devel.x86_64 libaio.x86_64 libX11.i686 libX11.x86_64 libX11-common.noarch libXext.i686 libXext.x86_64 libXft.i686 libXft.x86_64 libXmu.i686 libXmu.x86_64 libXp.i686 libXp.x86_64 libXpm.x86_64 libXrender.i686 libXrender.x86_64 libXt.i686 libXt.x86_64 libXtst.i686 libXtst.x86_64 libcanberra-gtk2.x86_64 libgcc.i686 libgcc.x86_64 libstdc++.i686 libstdc++.x86_64 libstdc++-devel.x86_64 libuuid.i686 libuuid.x86_64 ntp.x86_64 openmotif.i686 openmotif.x86_64 openmotif22.i686 openmotif22.x86_64 pam.i686 patch.x86_64 sg3_utils.x86_64 tigervnc-server.x86_64 unzip.x86_64 xorg-x11-twm.x86_64 xorg-x11-xauth.x86_64 xterm.x86_64
The following packages does not exist in distro already (they obsolete). You should download them from RedHat 5 (or CentOS 5 suits too):
compat-glibc-2.3.4-2.26.i386 compat-glibc-2.3.4-2.26.x86_64 compat-glibc-headers-2.3.4-2.26.x86_64
Prepare RH6 as you like. (disable ipv6, etc...)
Do not forget to disable SELINUX, and iptables (even remove them).
# echo -e "*\t-\tnofile\t65535\n*\t-\tnproc\t16384\n*\t-\tmemlock\tunlimited" > /etc/security/limits.d/sc.conf
Unpack DB2 installation files (DB2_10.5.fp6_LINUX.tar.gz) at temporary place, then run prerequisites check:
# ./db2prereqcheck > precheck.out
Look for "ERROR" lines in resulting file and fix errors. Rerun command to verify everything is OK.
IBM's installer is graphic tool, therefore start vncserver:
Connect to VNC session using viewer on your PC and start :
Click on Install a Product. Click on upper Install New button. Follow instruction accepting defaults. Do not define suggested notification unless you need it. Once finished, define DB2 instance to autostart after reboot:
# su - db2inst1 $ db2iauto -on db2inst1
Create SAMPLE database to verify installation:
# su - db2inst1 $ db2sampl $ db2 connect to sample $ db2 "select * from staff where dept = 20" $ db2 connect reset $ db2 drop database sample
Add user db2inst1 to root group (will be required later:
# usermod -aG root db2inst1
Reboot server to see DB2 comes automatically up. It does not comes immediately, wait for a minute.
In temporary space create directory jazz (important, some scripts have this name hardcoded). Unpack into this directory the following software
WAS_V126.96.36.199_FOR_JAZZSM_LINUX_ML.zip JAZZ_FOR_SM_188.8.131.52_FOR_LNX.zip ITCR_184.108.40.206_FOR_LINUX.tar.gz ITCR_220.127.116.11_FOR_LINUX.tar.gz
Unpack SPM_CTL_SERVER_V18.104.22.168_LINUX.tar.gz out of jazz directory. Unpacking will create SC directory. Unpack at same place license file. This should place SC/license/key/nodelock.AE at correct place. If not, you will be asked to point correct nodelock.AE file during installation.
Start vncserver (if not started) as root, connect to it.
# /opt/ibm/db2/V10.5/cfg/db2ln # source /home/db2inst1/sqllib/db2profile # cd /tmp/SC/ # ./setup.bin
Installer will detect DB2 already installed and will not propmt to install it. Next step to click Install now at "Cognos BI Reporting" section. At next window supply directory with unpacked software (if you followed me, it /tmp/jazz) and click Install now button. Firefox window will opened, select Custom installation. Click Next until "Select Operations" window appear. Change every operation to None, install only "Reporting services" and "IBM Webshere Application Server". Supply correct DB2 user (db2inst1) and password when asked.
Once everything in green state, click on Exit link on the left. Firefox window will closed and you will return to previous installer. Click OK.
Click Next, accept defaults and supply correct usernames and passwords.
Manual start procedure:
# /opt/IBM/JazzSM/profile/bin/startServer.sh server1
Remove /src directory if needed.
Reduce /tmp size to 1G
Poweroff server and reduce it's memory to 8G.
