Soa suite 11.1.1.4 & Grid 12C

Question

Periodically in Grid 12C and Grid 11 we have got database soainfra workload and we have find it that this is becouse of very strange select SELECT COUNT(*) FROM CUBE_INSTANCE ci WHERE ci.COMPONENTTYPE = :1 AND ci.STATE IN (6, 10) and we receive about 20 selects like this in 1 minute. Had anyone this situation?

Hello Anuj,
Thanks for replay.
This is request from soainfra (JDBC Thin Client).
I have AWR report:
