I am about to tune a small db which is having 100 tables. The db was created with OEM by mycollegues. While I check that schema I have found the following schema
-QS, QS_ADM, QS_CBABM, QS_CS, QS_ES, QS_OS, QS_WS.

My project has only one schema. It is having java scripts too.

So in this case may I remove those schemas. Will it affect any of the
other services?
