Active the installed adapters in Oracle SOA suite.

Recently, I installed the latest version of Oracle SOA Suite, but I found there are some adapters' status is not active, such as SocketApdater and OracleAppsAdapter. Googled on the internet and found somebody said these adapters weren't deployed to a target server. I checked the setting of these adapters on targets tab and it is true. By selecting the target server, the adapter becomes active and then the configuration works.
