Due to server tuning, you need to migrate the database tablespace file about 2T above server A to another server B on the same network segment.Specifically, n 32G tablespace file (note that it is a single file 32G)The local area network transmits the file the tool many, but did not think is, once processing such a large document, the basic whole rest vegetable.First try the FEIQ, the transmission speed is very fast, 1000M network card speed can reach

Merge k sorted linked lists and return it as one sorted list. Analyze and describe its complexity.The title means merging K ordered lists into an ordered list.Ideas:Using merge sorting, the plot is as follows:Only in the K-linked list merge, the figure of 10 4 6 and other elements into the list, need Mergetwolist (A, b), the same as the K-linked list as an element of the K elements, 22 mergesThe code is as follows:/** * Definition for singly-linked list. * struct ListNode {* int val; * ListNode

Because it is a segmented point, by definition\[F ' (0) =\lim_{x\to 0} \frac{\frac{\int_0^x (e^{t^2}-1) DT}{x^2}-f (0)}{x}=\lim_{x\to 0} \frac{{\int_0^x (e^{t^2}-1) DT}}{ X^3}=\lim_{x\to 0} \frac{e^{x^2}-1}{3x^2} =\frac13.\]4. Assuming that the $x >2$, $t =\frac 1x$\[\mbox{Original}=-\int \frac{t}{\sqrt{1-(

cost of the current project activity or project. Advantages cost less, less time consuming, the disadvantage is that the accuracy is low. 3. Parameter estimation: Use statistical relationships between historical data and other variables to estimate activity parameters such as cost, budget, and duration. The estimation accuracy depends on the maturity of the parametric model and the reliability of the underlying data. 4. Three-point estimate: There are two ways to be the most optimistic, most li

time. Then this trajectory can be used as an easing formula.SoHow do we use the two-time function to do the easing? Very simple, everyone with my ideas come. We want to design an easing interface API, if it is similar to the following, we first think of the simplest way."Known": an object to run from 0 to 400 with a running time of 1 seconds (1000ms).So how do we design a two-time easing of the function for it? Let's draw one first:So the coefficients of the equation a = 0.00005, B =-0.1;Then t

1, first talk about the hardware configuration, I started in Win7 (I7 4770,8g ram,2t hard disk) installed ubuntu10.10 64-bit system (4G ram,200g hard disk) to compile the source code, about 3 hours spent. and several outofmemoryerror errors have occurred. Finally, the hardware upgrade to I7 4770, 16G memory, 2T hard disk, do not install virtual machine, run the Ubuntu 10.10 system directly, swap partition 1

, the file is too small may be a few k, then the unit is displayed in K, if large to a few g, it is displayed in units of G.The-c option is the last addition, and this option is not used.-s only lists the sum, which is used the most.FDISK is used to partition a disk with a size less than or equal to 2T, if greater than 2T requires the parted toolFDISK command syntax: fdisk [-l] [device name] option has only

reasons:The A.dell server needs to configure RAID and partition initialization when installing the ESXI system (it is important to note that the pre-set system disk is smaller than the 2T,MBR only supports 2T HDD, ESXi is based on the Linux kernel)Mode of SATA in B.biosC. Drive issuesAfter finishing the online solution, first configure the server RAID, the general new purchase of the server will have a con

record. The next 64 bytes are the partition table (MBR partition table), and the last two bytes are 55AA (this is the MBR end flag).Because there are only 64-byte partitioned tables, there can be only 4 primary partitions (16 bytes per record) in the partition table of the MBR structure, and the maximum size per partition (2T) is also limited. So, more than 2T of hard disk, to use GPT partition table, abou

If the total capacity of the hard disk is greater than 2T, the system cannot be installed in MBR format.Use GPT formatYou can't use Fdisk to partition it at this time.To use parted to partitionMore than 2t hard disk partition, the old boy video used to 5 pieces of 600G hard diskThere are several ways to install the systemI only remember two of them.Method One: Take 2 pieces of RAID 1 for the remaining 3 pie

Polynomial evaluationSuppose there is a sequence of n+2 real a0,a1,..., An and X, to find the polynomialP_NX = a_nx^n + a_n-1x^n-1 + ... + a_1x + a_0;You need multiplication: n+n-1 + ... +2+1 = n (n+1)/2Need addition: NVisible algorithm efficiency is O (n^2)and P_nx = ((... (((((a_n) x + a_n-1) x + a_n-2) x + a_n-3) ...) X + a_1x) + a_0So the idea:p_0x = A_np_1x = xp_0x + a_n-1p_2x = xp_2x + a_n-2......P_NX = xp_n-1x + a_0Complexity of Time:Make t (n) The sum of the addition and multiplication r

algorithm to combine the two parts together3) Merging algorithm:Take two input array A, B, an output array C, 3 counters pa,pb,pc, initially placed in the corresponding array header;The smaller of A[pa] and B[PB] is copied to the next position in C, and the relevant counter advances one step forward;When one of the two input tables is exhausted, copy the remaining parts of the other table to C.eg. Original Array {24,15,1,26,13,27,2,28}Split:Merge:Complexity of Time: The run time for merge sort

the last, the remaining elements are less than two of the length of the subsequence: If the remaining number of elements is greater than the length t of a subsequence, then the merge sub-algorithm merge is called once, merging the remaining two unequal subsequence sequences into an ordered subsequence If the remaining number of elements is less than or equal to the length of a subsequence, only the remaining elements should be copied sequentially to the back of the previous sub-seq

Two ways to optimizeOptimization One: Use Insert sort when the le
