कोई मास्टर Database से Application को चलाने की कोशिश करे, तब हम as a DBA adjust नहीं करते, ये डेटाबेस, दूसरे databases की छाया नहीं है, बल्कि एक मजबूत टहनी की तरह है, जब भी कहीं ये used दिखे, हमें suspect मोड situation की याद आनी चाहिए!
Additionally,
बहुत ज्यादा नहीं पर checkpoint की frequency तो होती ही है, जो हम अपने हिसाब से बदल भी सकते हैं, पर Source of Checkpoint हमारा procedure या script भी हो सकती है, समय की कीमत अगर जान कर हम लॉग को लगातार truncate करते रहें या इस एक रेंज के databases को simple recovery में shift कर दें तो space issue Logspace की वजह से कभी नहीं आयेगा!
