It is a good practice to create dedicate cluster services for eBS environments running on RAC:
export LDB=ebsdb
srvctl add service -d ${LDB} -s ${LDB}_forms -r ${LDB}1,${LDB}2
srvctl add service -d ${LDB} -s ${LDB}_ssa -r ${LDB}1,${LDB}2
srvctl add service -d ${LDB} -s ${LDB}_batch -r ${LDB}1,${LDB}2
srvctl add service -d ${LDB} -s ${LDB}_batcha -r ${LDB}1 -a ${LDB}2
srvctl add service -d ${LDB} -s ${LDB}_batchb -r ${LDB}2 -a ${LDB}1
srvctl start service -d ${LDB} -s ${LDB}_forms
srvctl start service -d ${LDB} -s ${LDB}_ssa
srvctl start service -d ${LDB} -s ${LDB}_batch
srvctl start service -d ${LDB} -s ${LDB}_batcha
srvctl start service -d ${LDB} -s ${LDB}_batchb
