For the Cognos part of IBM Connections together with an Oracle database you need to install the 32-bit Oracle database client on your Cognos node. Cognos is only supporting the “Runtime-Client” and not the smaller “InstantClient”, so make sure you choose the right one.
Below I describe the steps how to install the client on your Cognos node:
Assumptions:
Path where to install the client: “/opt/oracleclient”
Linux user for the Oracle client (cannot be installed as root!): oraleclient
inventory_loc=/opt/oracleclient/app/oraInventory inst_group=users
[/codesyntax]
cp /etc/services /etc/services.OLD sed -i '/^#/d' /etc/services
[/codesyntax]
If you do not do that, then the installation program might hang at about 60% during “Copying files for ‘Oracle Notification Service'” (at least this was the case for me with SuSE Enterprise Linux (SLES) Version 11)
[codesyntax lang=”bash”]
cd /tmp/CVU_11.2.0.1.0_oracleclient/ ./runfixup.sh
[/codesyntax]
Result is something similar like that:
[codesyntax lang=”text”]
Response file being used is :./fixup.response Enable file being used is :./fixup.enable Log file location: ./orarun.log Setting Kernel Parameters... fs.file-max = 8192 fs.file-max = 6815744 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.wmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_max = 1048576
[/codesyntax]
After the scripts has been run click “OK” and then continue with the installation program.
During the installation of the client a new window will pop up:
You need again to open a second command line window as user “root” and run the script mentioned in that window:
[codesyntax lang=”bash”]
/opt/oracleclient/product/11.2.0/client_1/root.sh
[/codesyntax]
The script is asking for the full pathname of the local bin directory. Just type ENTER to use the default value of “/usr/local/bin”.
The output is something similar like that:
[codesyntax lang=”text”]
Running Oracle 11g root.sh script... The following environment variables are set as: ORACLE_OWNER= oracleclient ORACLE_HOME= /opt/oracleclient/product/11.2.0/client_1 Enter the full pathname of the local bin directory: [/usr/local/bin]: Copying dbhome to /usr/local/bin ... Copying oraenv to /usr/local/bin ... Copying coraenv to /usr/local/bin ... Creating /etc/oratab file... Entries will be added to the /etc/oratab file as needed by Database Configuration Assistant when a database is created Finished running generic part of root.sh script. Now product-specific root actions will be performed.
[/codesyntax]
export ORACLE_OWNER=oracleclient export ORACLE_HOME=/opt/oracleclient/product/11.2.0/client_1 export PATH=$ORACLE_HOME/bin:$PATH export LD_LIBRARY_PATH=/opt/IBM/Cognos/CognosBI/bin64:$ORACLE_HOME/lib:$LD_LIBRARY_PATH export TNS_ADMIN=$ORACLE_HOME/network/admin
[/codesyntax]
conn50_db = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = <db server hostname>)(PORT = <db server port>)) ) (CONNECT_DATA = (SERVICE_NAME = CONN50P) ) )
[/codesyntax]
sqlplus metricsuser/[password for metricsuser]@[alias you defined above, like CONN50_DB]
[/codesyntax]
The output should look like that:
[codesyntax lang=”text”]

[/codesyntax]
SELECT table_name FROM all_tables WHERE owner = 'METRICS';
[/codesyntax]
You should see all tables with owner name “METRICS” be listed:
[codesyntax lang=”text”]

Enter "QUIT" fo leave the SQLPLUS prompt.
