Solution:

Check the oraparam.ini file located under $ORACLE_HOME/oui

Edit the value of JRE_LOCATION and set is as below, which points to jre located inside the ORACLE_HOME

vi oraparam.ini

Re-run the attach home :

cd $ORACLE_HOME/oui/bin

./runInstaller -silent -attachHome ORACLE_HOME="/im/<inst_id>/apps/tech_st/10.1.2" ORACLE_HOME_NAME="<INST_ID>_TOOLS"
