Hello Manthan,
There are 2 options to install BI 4.1 on the second node :
1. Install BI 4.1 with default DB.
2. Install BI 4.1 by providing the DB credentials of the primary node
With the first option, the SQL Anywhere client will be installed and the obdc.ini (<BIP_INSTALL_DIR>/sap_bobj/enterprise_xi40/odbc.ini) configured to connect to the local DB. You can then modify it to connect to the DB on the primary node. For example,
[ODBC Data Sources]
BI4_CMS_DSN_DEV=SQLAnywhere 12.0
[BI4_CMS_DSN_DEV]
UID=dba
PWD=mypassword
DatabaseName=BI4_CMS
ServerName=BI4_DEV
Host=192.168.1.10:2638
Driver=/opt/sqlanywhere12/lib64/libdbodbc12.so
Modify it accordingly to have the right information for connecting to the primary node (servername, host, port, etc) . You can check the odbc.ini file on the primary node to confirm the same.
With the second option, you need to download and install the 64-bit SQL Anywhere client for AIX manually. Once done, modify the odbc.ini as mentioned above.
I would recommend the first option as this also gives us an idea if the product has been properly installed with the default DB.

Kunal
