very long period, the market can no longer accept such a long wait, "so we are adjusting, to faster, more accurate deployment, so that customers quickly get value." ”Oracle in 2016 acquired the SME-oriented ERP cloud service provider NetSuite, is directed at this idea. "Oracle SaaS has three big clouds, ERP cloud, CX Cloud and HCM Cloud, like the ' Sea, land and air ' army. In addition to the ' Sea, land and air ' service, we also need to
In IPv6 technology, the address structure is worth further learning. The biggest difference between IPv6 and IPv4 is that IPv6 technology defines globally multicast addresses that can be clustered. This new concept may be vague, so we will explain this concept in this article.
What is an IPv6 clustered global unicast address?
The IPv6 protocol technology designs an Address with a hierarchical structure for point-to-point communication. This Address is called Aggregatable Global Unicast Address,

RES reserved for future TLA or NLA extension. TLA is a public network access point that is connected to long-distance service providers and telephone companies. It obtains the address from an inter

Besides the address space of 128 bits, IPv6 also designs an address with a hierarchical structure for point-to-point communication, called the Aggregately glob-al unicast address )。

MySQL replication technology is a log of the replication process, during the replication process one server as the primary server, and one or more other servers acting as slave servers, simply speaking, from the server to the master server pull binary log files, The log file is then parsed into the appropriate SQL to re-perform the operation of the primary server on the server, in this way to ensure data consistency.MySQL replication tec

, enter your TestCase name, and then click OK.5. Next, the dialog box Add Request to TestCase will appear. Click OK.6. When the request is created as TESTREQUESTB, SOAPUI will automatically generate a testsuite and testcase for you. The following is a copy of the request that appears on the interface.The next step is to verify the response of the test by asserting the assertion.2. Add an assertion testNow that we've created and run our first Test, we're going to add a response to the validation.
Some time ago, I made a stateless TCP conntrack and found that one of the static arrays represents a good TCP state machine. I hope this idea can be used in practical work. Let's just say, this is the state machine array:
static const u8 tcp_conntracks[2][6][TCP_CONNTRACK_MAX] = { {/* ORIGINAL *//* sNO, sSS, sSR, sES, sFW, sCW, sLA, sTW, sCL, sS2 *//*syn*/ { sSS, sSS, sIG, sIG, sIG, sIG, sIG, sSS, sSS, sS2 },/*...};

merge, you must first define the merge goals for your merged teams and customers, and for the business owners of the user database. These goals are different depending on how you merge: Merging on a virtual machine, piling up a SQL Server environment, and using a storage area network (SAN), and so on.
It is critical that the merge team discuss the actual service level agreement (SLA) with the customer beforehand. These SLAs provide more than just ex
