यह 40 लेता है किसी भी आवेदन के बिना जावा आदेश शुरू करने के लिए। जेआरई (64 बिट) वेबस्पेयर वी 8 का हिस्सा है, और 20 मिनट की आवश्यकता है। एप्लिकेशन सर्वर शुरू करने के लिए।
उसी एईक्स में, एक और जेआरई (32 बिट) है, यह बहुत अच्छी तरह से काम करता है।

मैं का उपयोग कर truss.When जावा शुरूआत करने जा रहा है, यह एक लंबे समय के लिए thread_tsleep() पर अवरुद्ध है कुछ बात पाया। क्यूं कर? इसे कैसे ठीक करें?

अद्यतन
साथ
मैं इस विषय पाया, और मेरे AIX पर कार्यक्रम का परीक्षण करें। होस्टनाम का उपयोग करते समय, यह DNS क्वेरी के लिए लगभग 40 के लिए देरी हुई। आईपी पता सामान्य है।
Java cannot resolve DNS address from AIX: UnknownHostException
वैसे, होस्ट नाम server3 से पता चलता है, जब मैं नाम पिंग, यह पता चलता है: PING server3.cf1.xx.xxxx.com ..... मैं server3 का उपयोग कर कार्यक्रम चलाने .cf1.xx.xxxx.com, कोई देरी नहीं है।
Update2:
यह IPv6 समस्या है। यदि मैं -Djava.net.preferIPv4Stack = true जोड़ता हूं, जावा एप्लिकेशन अच्छी तरह से चलता है। लेकिन जावा कमांड अभी भी DNS क्वेरी करने के लिए आईपीवी 6 का उपयोग करता है। तो जावा कमांड में 40s देरी है, और जावा एप्लिकेशन में DNS क्वेरी पर कोई डेली नहीं है।
क्या मैं जावा पैरामीटर नहीं, एईक्स में आईपीवी 4 में डिफ़ॉल्ट प्रोटोकॉल सेट कर सकता हूं?
मैं टाइम स्टांप जोड़ने । मेजबान कोई समस्या नहीं है। 127.0.0.1 लूपबैक लोकलहोस्ट # लूपबैक (lo0) नाम/पता 1 9 2.168.62.117 सर्वर 3 – culy
