Server related DMVs in SQL Server

Antonios Chatzipavlis

Πολλές φορές ένας DBA ψάχνει να βρει πληροφορίες για το configuration ενός instance. Από όσο έχω δει μέχρι τώρα οι περισσότεροι καταφεύγουν στο γραφικό περιβάλλον ίσως από ευκολία ή μήπως επειδή δεν γνωρίζουν άλλον τρόπο;

Στο SQL Server υπάρχουν τρεις αρκετά χρήσιμες DMV με τις οποίες μπορούμε να δούμε αρκετά χρήσιμες πληροφορίες για το configuration του instance και αυτές είναι οι παρακάτω


sys.dm_server_services

Επιστρέφει πληροφορίες για τα SQL Server, SQL Agent, FTS services όπως το startup mode του service, το status, το process id, το πότε (date & time) που αυτό έχει ξεκινήσει, το account που ξεκινάει το service αν είναι σε cluster και αν έχει ενεργοποιημένο το instant file initialization.


sys.dm_server_registry

Επιστρέφει πληροφορίες για όλα τα configuration instance settings που αποθηκεύονται στην registry, και πιστέψτε με τα λέει όλα και είναι από τις αγαπημένες μου.


sys.dm_server_memory_dumps

Επιστρέφει μια γραμμή για κάθε memory dump που έχει δημιουργηθεί αυτόματα από το SQL Server database engine. Καλό είναι να μην έχουμε αποτελέσματα από την εκτέλεση της, αλλιώς θα πρέπει να το ψάξουμε.
