SAP DMS Content Repository Configuration in OAC0

Hello All,

Could any one explain me who is responsible person for the configuartion of Content Repository & Content server Administration i.e. /OAC0 Transaction in IMG?

Whether it is BASIS Administrator or it should be done by DMS Functional consultant? I need this information as I am a DMS functional consulatnt & I am not much sure how to do this configuration of DMS server.
