The trim fixdisables the overriding feature.Solution: A simple fix will be made to keep the trim fix intact. Trimming is done only forattributes with non-blank characters.

InstallationThis section provides general guidelines to apply a Fix Pack to Trigo Product Center. Someinformation may differ depending on the methods used for previous installations. Contact your support representative for Trigo Product Center with any installation issues.4.1 Installation notesPreviously, it was necessary to perform a full installation for all files. The current installationprocess only updates the files that have changed to the current working version directory.4.1.1 Removal of J2EE and JSSECR: P12188Due to new company guidelines, J2EE and JSSE are no longer bundled as part of the Trigoinstallation file. This is not an issue for customers using WebSphere or WebLogic, only customers using Tomcat.J2EE - Java 2 Platform, Enterprise EditionJ2EE is a Trigo prerequisite with the use of Tomcat; therefore the J2EE JAR file, which is part of “Version 1.3.1 of the Java 2 SDK, Enterprise Edition ("J2EE" SDK)”, will need to be downloaded by the customer from the Sun Microsystems website (/j2ee/sdk_1.3/). Follow the instructions on the website to download and install the entire J2EE SDK.Note: The J2EE jar file is included in the J2EE SDK tar file.Figure 1 - Link to download J2EE SDK tar fileOnce this tar file is downloaded, it is extracted to a location defined by the customer.Since j2ee.jar is no longer included when a Trigo enterprise build is created and it is a prerequisite for Trigo Product Center, the following environment variable needs to be set to identify the location of the j2ee.jar file. The environment variable is defined in the init_trigo_vars.sh file.File to edit:$TOP/setup/init_trigo_vars.shEnvironment variable:J2EE_JAR=(location of j2ee.jar file including the file name)For Example:J2EE_JAR=/opt/j2sdkee1.3.1/lib/j2ee.jarNote: This step is not required for WebSphere or WebLogic.JSSE - Java Secure Socket ExtensionJSSE was being used to provide HTTPS post functionality. After careful review, it was determined that this functionality was not being used, therefore the functionality and the associated JAR file were removed.4.2 PreparationBefore attempting to apply the latest Fix Pack to Trigo Product Center, the following preparation is recommended:4.2.1 Stopping the whole application on the local machineComplete the following steps to stop the Trigo Product Center instance:1. Check the scheduler to make sure there are no critical jobs that need to be completed.If the queue is clear, kill the scheduler manually by running the script:$TOP/bin/go/stop/stop_scheduler.sh2. Abort the entire application by running the script:$TOP/bin/go/abort_local.shAll services running on the local machine are aborted. The RMI registry is aborted.Note: Check to make sure all processes have stopped using the 'ps' command.Kill any rogue "java" or "rmiregistry" processes that remain after shutting down the instance.Occasionally, it may take several attempts to kill all java processes.4.2.2 Backup•Create a full backup of the current Trigo Product Center directories before applying the Fix Pack. The Fix Pack will overwrite files that have changed. If any issues occur, thebackup will allow a rollback to a previous version•It is recommended to apply the Fix Pack to a test system to identify any issues before applying the Fix Pack to a production system•Perform a full backup of the database before applying the Fix Pack to a production system Note: Do not delete the old Trigo Product Center version until thorough testing of the new installation is completed.4.2.3 Delete Tomcat working directoryFor configurations using Tomcat, delete the Tomcat working directory using the followingcommand:rm -rf $TOP/etc/default/tomcat33/webapps/ccdOnce the working directory has been deleted, begin the application of the Fix Pack.4.3 Apply Fix PackTo apply the Fix Pack to Trigo Product Center, complete the following tasks:Unpack tar fileUpdate configuration filesTest installation4.3.1 Unpack tar filePurpose: To extract and update any new installation files into the current working directoryNote: GNU tar is needed to untar the Trigo Product Center files.1.Copy the Trigo Product Center tar file to the user or temporary directory.Example:{HOME_OF_TRIGO}/tarballs2. CD to $TOP, the current working directory, and unpack the tar file:Using GNU tar, the following command extracts and unzips the tar file:Example:Tar using an absolute path:tar zxvf /home/trigo/tarballs/trigo_4107a_05_fixpak_tom_ora.tgz 4.3.2 Verify configuration filesVerify all configuration files required by the new installation and make any updates as needed.Refer to the backup copy of the configuration files for the previous installation if needed.austin.propertiesadmin_properties.xmlinit_trigo_vars.shTrigo license fileaustin.propertiesOn startup, the system will use this file to read in all system level parameters. This fileincludes settings for the database layer (connection parameters), directory settings,default character sets, thread-pooling parameters, and other settings, which aredocumented in the file.File location: $TOP/etcadmin_properties.xmlThis file is used by the administrative utilities to configure clusters of the application.File location: $TOP/etcinit_trigo_vars.shThe initialization file is the shell script that initializes the shell variables used by thesystem.File location: $TOP/setupTrigo License FileThe license file contains the license keys needed to use the Trigo application.File location: $TOP/etc/runtime4.4 Test installation4.4.1 Start Trigo Product CenterTo start the Trigo Product Center, execute the following script:$TOP/bin/go/start_local.shThe script starts all the services required to run Trigo Product Center.Note: This process should take approximately 30-40 seconds, depending on the speed of the processor.4.4.2 Check statusRun the $TOP/bin/go/rmi_status.sh script that was provided by Trigo Product Center andverify the following services have started correctly.•admin_<machine name>•appsvr_<machine name>•eventprocessor•queuemanager•scheduler•workflowYOU HAVE SUCCESSFULLY APPLIED THE LATEST MAINTENACE RELEASE FOR TRIGO PRODUCT CENTER!NoticesIBM may not offer the products, services, or features discussed in this document in all countries.

2009年12月大学英语四级考试答案详解Part ⅠWritingCreating a Green CampusRecently, with the idea of making and maintaining “a green earth”being the focus of the society, “green campus” has become a more and more popular concept in universities or colleges, which, undoubtedly, will bring us an ever-lasting benefit to both our campus and our society.The concept of “green campus” does not only mean a green environment but also refers to an environmental sense in people’s mind. Campus plays a crucial role in educating the young generation and the consciousness of “green campus” will definitely produce a profound effect on students’ various environmental protection activities after their graduation. What’s more, the young generation is under the burden of severe environmental pollution and there are many problems waiting for them to solve.To make “green campus” come true, firstly, it is necessary to work out effective principles for the development of sustainable and recyclable campus. Secondly, it calls for people’s awareness of the serious pollution around us and actual action to reduce the waste. Last but not least, it is necessary to strengthen the ties between campus and society, so as to ensure that “green campus” can work smoothly with the co-effort of the whole society.Part ⅡReading Comprehension (Skimming and Scanning)篇章结构核心词汇1. aid n. ①帮助，援助②助手v. 帮助，援助【用】financial aid经济援助;merit aid/ Merit-based奖学金;need-based aid助学金或经济资助;foreign aid外援，对外援助;hearing aid助听器;aids and appliances用具，设备【搭】in aid to用来帮助，起……作用;lead one’s aid (to)援助，给予帮助;in aid of作为援助……之【拓】aidance n. 协助，帮助;aidant a. 帮助的;aided a. 辅助的2. project v. ①设计②发射n. 事业，计划，工程【用】Project Hope希望工程;project manager项目经理;project plan项目规划;project budget 项目预算，工程预算【拓】projection n. 突出，发射;projecting a. 突出的3. selective a. 选择性的【用】selective analysis重点分析;selective breeding选择育种，选择性繁殖【拓】select v. 挑选，选拔a. 精选的;selection n. 选择，挑选，选集4. package n. 包裹;套装软件，程序包a. 一揽子的【用】package design包装设计;package agreement一揽子安排，一揽子方案;package holiday(旅行社安排一切的)一揽子旅游;package tour包办旅行(路线、地点、时间和费用等均作统一规定和安排的旅游);package program组装程序【拓】pack n.包装，背包v. 包装，压紧;packaged a. 袋装的;packager n. 打包机5. ranking a. 头等的;n. 等级，地位【用】ranking list排名;ranking method等级法，排序法【拓】rank n. 等级;队列;v. 排列，6. grant v. ①授予②承认;n. ①授予物②拨款【用】grant of a patent授予专利权【搭】take…for granted认为……是理所当然; Granted/Granting that即使……(也)【拓】grants n. 补助金，津贴(grant的复数)7. enrol v. 登记，入学，参军，注册【搭】enrol in选课，参加【拓】enrollment n. 登记，入伍;enrollee n. 入学者，入伍者8. eliminate v. 消除，排除【用】eliminate illiteracy扫盲;eliminate poverty消除贫困;eliminate noise 消除噪声【拓】eliminate 是指把已进入者从中排除;exclude v. 指把想进入者拒之门外9. qualify v. 使具有资格，证明……合格【用】qualifying examination资格考试，初试;qualifying competition预选赛，资格赛【搭】qualify as 取得……资格，作为……合适;qualify for有……的资格，合格【拓】qualified a. 有资格的，合格的10. excel v. 胜过，优于，擅长n.

Begin paup后面的一段命令是在paup中运行，来执行这个模型的命令。
3． 在开始－运行中输入cmd命令，确认，弹出一个dos界面的窗口，将其默认目录改为model.scores文件所在文件夹，修改方式为在dos窗口输入：cd 盘符：\filename\filename，确认，这里我们输入
cd C:\modeltest3.7\” Modeltest3.7 folder” \bin\。带有空格的文件夹名要用双引号括起来。

1. 首先用Clustal X进行序列比对：要保证：保证核苷酸序列是三的倍数，没有终止密码子，核苷酸序列的第一位是密码子的第一位。假设序列名为cox1.fas
5、然后点击左边的按钮“select file”，找到“model.scores”，之后，点击按钮
“Modeltest！！”，然后就会出现运行结果了。
6、会出现两个运行结果，一个是hLRT得出的结果，另一个是AIC给出的结果。

计算不同model下的似然值。如果序列比较多，且长的话，需要计算一阵呢！

python核心编程第二版第7章习题答案
7-1.字典方法。
哪个字典方法可以用来把两个字典合并到一起。
答案：dict.update(dict2)将字典dict2的键-值对添加到字典dict中7-2.字典的键。
我们知道字典的值可以是任意的Python对象，那字典的键又如何呢？请试着将除数字和字符串意外的其他不同类型的对象作为字典的键，看看哪些类型可以，哪些不行。
对那些不能作为字典的键的对象类型，你认为是什么原因呢？答案：键必须是可哈希的。
所有不可变的类型都是可哈希的，因此他们都可以作为字典的键。
一个要说明的问题是：值相等的数字表示相同的键。
换句话说，整型数字1和浮点型1.0的哈希值是相同的，即它们是相同的键。
同时，也有一些可变对象(很少)是可哈希的，它们可以作为字典的键，但很少见。
用元组做有效的键，必须要加限制：元组中只包括像数字和字符串这样的不可变参数，才可以作为字典中有效的键。
内建函数hash()可以判断某个对象是否可以做一个字典的键，如果非可哈希类型作为参数传递给hash()方法，会产生TypeError错误，否则会产生hash值，整数。

Then he lay down on the ground and went to sleep. It was late in the afternoon when he awoke. He was just about to jump up when he felt something moving near his feet. He looked down. A long black snake was just about to crawl across his legs. John watched, too frightened to do anything.
