java - How to view/change socket connection timeout on Linux? -

-

जावा में एक सॉकेट बनाते समय: 

  नया सॉकेट (होस्ट, पोर्ट);

सॉकेट कन्स्ट्रक्टर आने से पहले host: port से कनेक्ट करने का प्रयास करेगा। विंडोज़ पर, यह अप्राप्य मेजबान के लिए लगभग तुरंत विफल हो जाता है, लेकिन लिनक्स के लिए सॉकेट से टाइमआउट के लिए 5 मिनट लग सकते हैं।

मुझे पता है कि अगर मुझे सॉकेट बनाने पर नियंत्रण है, तो मैं कर सकता हूँ :

<पूर्व> सॉकेट एस = नया सॉकेट (); s.bind (..); S.connect (.., टाइमआउट);

लेकिन मेरे पास ओएस एक उचित डिफ़ॉल्ट मान का उपयोग करना होगा। क्या लिनक्स पर इस सेटिंग को बदलने का कोई तरीका है?

धन्यवाद

मुझे लगता है आप / proc / sys / net / ipv4 / tcp_syn_retries चाहते हैं डिफ़ॉल्ट रूप से आमतौर पर 5 या 6 जो लगभग 3 मिनट तक आती है।

ध्यान दें कि ये सिस्टम-व्यापी हैं।

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
