I have many dblinks to various databases. Each hour one db job is running which
uses these dblinks. But sometimes happens that some changes are made (e.g. IP

"SQL*Net message from dblink" wait event for a very long time.
Is there some possibility to set some "dblink timeout" or to simply check the
dblink status before?
