websphere-application-server问题诊断培训讲学

websphere-application-server问题诊断培训讲学

第一章websphere问题类型:1.不能migrate Websphere Application Server或者不能安装应用程序。

2.WAS管理和配置方面的问题。

3.一个应用程序或者websphere application server进程不能启动。

4.应用程序不能响应用户请求。

5.一个应用程序处理后得到unexpected results(errors/exceptions)。

6.应用程序无法连接外部系统或资源。

7.应用响应缓慢或者随着时间推移性能下降。

预防问问题几种途径:1.查询IBM官方网站的APAR,下载产品问题补丁,升级产品以便预防问题。

2.检查was基础硬件和软件环境,确保满足was运行的基本需求。

3.对部署在was上面的应用做全面的测试。

4.维护一套同生产环境完全相同的一套测试环境(硬件、网络……)。

5.定义一套安全的操作流程。

确定具体角色的明确职责。

6.领用V6以后的版本“集群”的新特性,解决高可用和容错管理。

7.通过监控预防问题发生。

8.记录应用运行环境下的所有变化。

9.为问题诊断收集数据发生问题的时候作什么1.恢复成长的生产环境2.鉴别问题症状a.观察到的问题具体症状是什么?是否有报错?应用程序是否产生了一个unexpectedresult?应用是否对所有请求都不予响应了?b.问题发生的上下文是什么?用户是否执行什么特定操作?是否在一个异常的高负载情况下发生的问题?是否在应用重启之后就发生了问题?c.如何知道这种问题何时产生?是否有一个标志性的特征表明问题再次发生?d.如何知道问题已经解决了?是否不会再产生其他的错误信息了?应用程序的行为是否变化了?怎么显式地证明问题已经解决了?e.问题出在哪个部分?问题是否只在测试环境出现,或者只在生产环境出现,或者两套环境都出现了?问题是否只在一套系统出现?是否在多套系统环境中都出现了这个问题?问题是出现在集群的每个成员还是只出现在其中的一个成员上?f.问题什么时候产生?发生问题的和健康状态的时间分解点是什么时候?问题发生了一次还是多次?问题的发生频率?是定期发生还是时间点上没有规律?是否有什么事件引发问题?g.问题可能因为什么发生的?是否有有什么特殊功能是第一次用到的?最近是否改过程序或者配置是否有所改变?如果只在一套环境中发生,这套环境与其他环境有什么不同?h.问题诊断数据是否收集了?诊断数据是否提示了问题所在?3.调查研究问题。

高级错误处理技巧使用trap和错误日志记录优化Shell脚本

高级错误处理技巧使用trap和错误日志记录优化Shell脚本

高级错误处理技巧使用trap和错误日志记录优化Shell脚本Shell脚本是一种用于自动化和批处理任务的编程语言,常用于Unix和Linux系统中。

然而,在编写和执行Shell脚本时,错误经常会发生。

为了改善脚本的可靠性和健壮性,我们可以使用一些高级错误处理技巧,如使用trap和错误日志记录。

本文将介绍如何使用trap和错误日志记录来优化Shell脚本的错误处理。

一、使用trap捕获和处理错误当Shell脚本遇到错误时,如果没有进行处理,将会直接中断执行并输出错误信息。

为了更好地处理错误,我们可以使用trap命令来捕获和处理错误。

trap命令可以设置一个或多个命令,当脚本遇到错误时,这些命令将会被执行。

在Shell脚本中,我们可以使用trap命令来设置一个错误处理函数,如下所示:```#!/bin/bash# 错误处理函数error_handler() {echo "脚本遇到错误,错误代码为:$?"# 其他错误处理操作exit 1}# 设置错误处理函数trap 'error_handler' ERR# 其他脚本内容...```在上面的脚本中,我们定义了一个错误处理函数error_handler,并使用trap命令将其与ERR信号关联起来。

当脚本遇到错误时,error_handler函数将被调用,并输出错误代码。

您可以在函数中添加其他错误处理操作,如日志记录、清理操作等。

二、优化错误日志记录除了使用trap命令来处理错误外,我们还可以通过错误日志记录来优化Shell脚本的错误处理。

通过记录错误信息到日志文件,我们可以更方便地查看和分析脚本执行过程中的错误情况。

在Shell脚本中,我们可以使用重定向操作符将错误信息输出到日志文件中,如下所示:```#!/bin/bash# 错误日志文件路径log_file="/var/log/myscript_error.log"# 错误处理函数error_handler() {echo "脚本遇到错误,错误代码为:$?"# 其他错误处理操作exit 1}# 设置错误处理函数trap 'error_handler' ERR# 执行脚本过程中可能产生的错误...# 将错误信息输出到日志文件exec 2>>"$log_file"# 其他脚本内容...```在上面的脚本中,我们定义了一个错误日志文件的路径,然后使用exec命令将错误信息重定向到该日志文件中。

Ascites(Think of CLD, Budd-Chiari, renal failure or heart failure, hypothyroidism, also malignancy, TB)PresentationSir, this patient has gross ascites.There is presence of abdominal distension with an everted umbilicus. There is a positive fluid thrill as well as shifting dullness. This is not associated with any abdominal tenderness and patient is able to lie flat for the examination. There is also abdominal scar marks suggesting abdominal tap has been done.I am unable to palpate the liver and it has a span of 12 cm in the right mid-clavicular line. The spleen is not palpable or percussible. The kidneys are not ballotable. There are no other masses palpable in the abdomen.There are no stigmata of chronic liver disease such as leukochynia, clubbing, palmar erythema, spider naevi, gynaecomastia or loss of axillary hair. There is also no hepatic fetor or a hepatic flap. Patient is not jaundice and there is no conjunctival pallor.There is associated pedal edema up to the knee level with sacral edema but no periorbital edema. There are no signs of renal failure such as a sallow appearance or uremic fetor.Patient also does not have any features to suggest hypothyroidism such as a cream and peaches complexion, macroglossia, hoarseness of voice or bradycardia.He is not cachexic looking and there are no palpable cervical LNs.

set-executionpolicy unrestricted 命令-概述说明以及解释

set-executionpolicy unrestricted 命令-概述说明以及解释1. 引言1.1 概述在计算机技术的发展中,安全性一直是一个非常重要的问题。

随着各种网络攻击和恶意软件的出现,保护计算机系统免受潜在的威胁变得越来越重要。

而在Windows操作系统中,PowerShell是一种强大的工具,它可以利用脚本语言来自动化执行各种系统管理任务。

然而,默认情况下,Windows PowerShell限制了可以运行的脚本的权限。

这是因为脚本的执行可能会带来潜在的安全风险,特别是当脚本来自未知来源时。

为了保护计算机系统的安全,Windows PowerShell默认将脚本的执行策略设置为限制模式。

然而,有时候我们需要在特定的情况下解除这个限制,以便能够运行脚本。

在这种情况下,可以使用"set-executionpolicy unrestricted"命令来修改PowerShell的执行策略,使得可以执行任何脚本,无论其来源是否可信。

本文将介绍set-executionpolicy unrestricted命令的概念、意义以及在实际应用中的一些注意事项。

首先,我们将提供一些背景知识,介绍PowerShell和脚本执行策略的基本概念。

接着,我们将详细探讨set-executionpolicy unrestricted命令的作用和意义,并说明在什么情况下使用它是有必要的。

最后,我们将总结这个命令的优缺点,并提供一些建议,来帮助读者在使用set-executionpolicy unrestricted命令时注意安全性和潜在的风险。

通过深入了解set-executionpolicy unrestricted命令,读者将能够更好地理解PowerShell脚本的执行策略,并在必要时灵活运用这个命令来满足自己的需求。

而在使用这个命令时,我们也要始终牢记系统安全的重要性,并采取适当的措施来确保脚本的来源可信和执行的安全性。

ANNEXURE1.1 IntroductionThis documents is supporting document, while installing Zipkin and ELK you may find reference.2. Document Tracing Zipkin2.1 Installation of Zipkin2.1.1 Download and RunningZipkin works as an independent application and it can be downloaded as a runnable jar from the official website of Zipkin : https://zipkin.io/. The latest version of Zipkin needs a Java version above 8.The direct download link of jar is as follows:https:///remote_content?g=io.zipkin&a=zipkin-server&v=LATEST&c=execThe downloaded jar can be executed using the java –jar JAR_NAME command.The configuration of Zipkin can be done environment variables. The port of the Zipkin can be set using QUERY_PORT environment variable.The application starts on the port number assigned for QUERY_PORT environment variable or its default value of 9411. The web UI of Zipkin can be accessed at http://localhost:PORT.2.2 Zipkin User InterfaceThe basic layout of Zipkin looks as followsWe can find the traces of required api calls and services using the above search options given in the user interface. The search options given in the user interface are self-explanatory and there is another UI option (Try Lens UI). It’s given a different user interface with same functionality.The list of the traces can be seen like the above screen. Some error API calls are made to showcase how to track errors. The blue listings show the successful API hits and the red listings indicate errors. Each block indicates a single trace in the listings.Opening an individual trace shows the below shown screen.The above shown image describes the time taken for each block. There are 2 custom spans created inside 2 service calls, so there are total of 4 blocks. The time taken for individual block can be seen above. Clicking an individual block shows the following details.The details of the specific span block are shown above and the logging events can also be seen in the Zipkin UI as small circular blocks. An example of error log is shown below.Clicking on the error portion gives the clear detail about the error and where the error has arised. AN example is shown below.If the Lens UI is used in Zipkin, the above screen shots are not applicable, but are relatable to the Lens UI as well.Traces of the application can be found using TraceId, which can be found in the debug logs of the deployment when spring-cloud-sleuth is included in the dependencies (Included in spring-cloud-starter-zipkin dependency). Clicking the dependency tab gives the dependency graph info between micro-services. An example dependency graph is shown below.3. Monitoring ELK3.1 IntroductionELK Stack was a collection of three open-source products — Elasticsearch, Logstash, and Kibana. Elasticsearch is an open source, full-text search and analysis engine, based on the Apache Lucene search engine. Logstash is a log aggregator that collects data from various input sources, executes different transformations and enhancements and then ships the data to various supported output destinations. Kibana is a visualization layer that works on top of Elasticsearch, providing users with the ability to analyze and visualize the data.Together, these different components are most commonly used for monitoring, troubleshooting and securing IT environments. Logstash take care of data collection and processing, Elasticsearch indexes and stores the data, and Kibana provides a user interface for querying the data and visualizing it.3.2 ArchitectureThe below architecture provides a comprehensive solution handling all the required facetsSpring cloud Sleuth also provides additional functionality to keep trace of the application calls by providing us a way to create intermediate logging events. So Spring Cloud Sleuth dependency must be added to applications.3.3 Installing & Configuring ELKTo install and configure ELK Stack, make sure the versions of the 3 software are same.
