मैं एसक्यूएल सर्वर 2008 R2 पर एक संग्रहीत प्रक्रिया के साथ एक बहुत ही अजीब मुद्दा है। कभी-कभी, हर महीने लगभग एक बार, मेरे पास एक प्रक्रिया है जो बहुत धीमी हो जाती है, कुछ मिलीसेकंड के बजाए चलाने के लिए लगभग 6sec लगती है। लेकिन अगर मैं इसे कुछ भी बदले बिना इसे फिर से संकलित करता हूं, तो यह फिर से चलता है। यह सभी संग्रहीत प्रक्रियाओं पर नहीं होता है, केवल एक (सर्वर पर कुछ सैकड़ों हैं)।संग्रहित प्रक्रिया तेजी के बाद पुन: संयोजित रन
मेरा अनुमान है जब एसपी संकलित किया गया है है, यह कैश किया गया है और यह कैश हर बार जब मैं इसे कहते पुन: उपयोग किया है, और यह कैश्ड संस्करण किसी कारण से दूषित हो जाता है।
मैं शायद कुछ लोगों को आशा व्यक्त की पहले से ही इस मुद्दे को इस तरह का सामना करना पड़ा, या कम से कम, सही दिशा में मुझे बिंदु सकता है SQL सर्वर या आईआईएस किस विन्यास संग्रहीत प्रक्रिया कैश को प्रभावित कर सकता है?
