It is not certified nor supported, but actually there is already a client installed in
MW_HOME/Oracle_BI1
SQL*Plus you say? Not to worry, there is an Instant Client as well available with the Times Ten software installed on the Exalytics server.
An example of running SQL*Plus from an Exalytics Server to test connectivity basd on the tnsnames.ora located in the the Oracle_BI1 home:
sudo su – oracle
cd
/u01/app/oracle/product/TimesTen/tt1122/ttoracle_home/instantclient_11_2
export LD_LIBRARY_PATH=$PWD:$LD_LIBRARY_PATH
export
TNS_ADMIN=/u01/app/oracle/product/fmw/Oracle_BI1/network/admin/
./sqlplus <schema>@<tnsname>
This is my narrow view on the world - if anybody reading this has any comments on other scenarios or cannot get the above to work, make sure you leave a comment below!
