如何解决出现无法与数据库服务器建立连接的方法在进行数据库开发和管理过程中，有时候会遇到无法与数据库服务器建立连接的问题。

这可能是由于各种原因引起的，包括网络问题、数据库配置错误、权限问题等。

在本文中，我们将探讨一些常见的解决方法，帮助您解决这个问题。

检查网络连接首先，我们需要确保您的计算机与数据库服务器之间的网络连接是正常的。

以下是一些检查网络连接的方法：1.确保您的计算机与数据库服务器在同一网络中。

如果它们不在同一个网络中，您可能需要设置网络访问规则或使用VPN来解决连接问题。

2.尝试使用其他网络设备（如手机）通过相同的网络连接尝试连接数据库服务器。

如果其他设备也无法建立连接，那么可能是网络设置或服务器故障引起的问题。

您可以联系网络管理员或服务器管理员以解决此问题。

检查数据库配置如果网络连接正常，下一步是检查数据库配置是否正确。

以下是一些检查数据库配置的方法：1.检查数据库服务器的IP地址和端口号是否正确。

您可以使用命令行工具（如ping命令）或网络工具（如telnet命令）来测试数据库服务器的可访问性。

2.如果您使用的是数据库管理工具（如phpMyAdmin），请确保在连接数据库时提供了正确的主机名、用户名和密码。

您还需要确保选择了正确的数据库引擎（如MySQL、PostgreSQL等）。

3.您还可以检查数据库服务器的配置文件，以确保数据库服务器已正确配置。

常见的数据库服务器配置文件包括f（MySQL）、postgresql.conf（PostgreSQL）、sqlnet.ora（Oracle）等。

检查数据库权限除了正确的网络连接和数据库配置外，还需要确保您具有足够的权限与数据库服务器建立连接。

以下是一些检查数据库权限的方法：1.检查您使用的数据库用户是否具有足够的权限。

如果您使用的是默认的管理员用户（如root用户），很可能会因为权限问题导致无法连接。

您可以尝试创建一个新的用户，并授予该用户必要的权限以进行数据库连接。

没有权限访问网络资源，如何解决？Unfortunately, there are several reasons why you might not have permission to access certain resources on the internet. This can be incredibly frustrating, but there are solutions and workarounds that you can try to remedy the situation.First and foremost, if you are trying to access a particular website or online service and are receiving an error message stating that you do not have permission to view the page, it is possible that the website itself is the issue. In this case, try accessing the site on a different browser or device. Occasionally, there may be compatibility problems with certain browsers or devices that prevent access to specific websites.Another potential reason for being denied access to a website or online content is due to regional restrictions. Some content may only be accessible from specific geographic locations, and attempting to access it from an unauthorized region will result in denial of access. To bypass this, you can use a Virtual Private Network (VPN) to change your IP address to one that is allowed to access the content.If you are trying to access a shared network resource, such as a file or folder on another computer within your organization, you may encounter permission issues if your user account does not have the appropriate access rights. In this case, you should contact your network administrator to request the necessary permissions.In some cases, restrictive network settings or firewall configurations may block access to certain websites or resources. If you suspect this is the issue, you can try accessing the website using a different network, such as a public Wi-Fi network or a cellular data connection.Finally, if you are unable to access a specific resource on the internet, it is also possible that the website or service itself is experiencing technical difficulties. In this case, there may not be much you can do until the issue is resolved on the website's end.There are several ways to resolve the issue of being unable to access network resources. By identifying the specific cause of the problem, whether it is a website issue, regionalrestriction, permission settings, or technical difficulties, you can take appropriate steps to address the issue and regain access to the desired resources.很不幸，你可能无法访问互联网上的某些资源有好几个原因。

Oracle® Java SE EmbeddedRelease NotesRelease 8 Update 6E53025-01July 2014These release notes describe its new features, platform requirements, installation,limitations, known problems and issues, and documentation for Oracle Java SEEmbedded.This document contains the following topics:■New and Changed Features■Platforms and Requirements■Installing Oracle Java SE Embedded■Known Issues■Limitations■Learning Resources■Documentation Accessibility1New and Changed FeaturesThe following features are new in Release 8 Update 6.1.1Reduction in Static Footprint of Custom JREsThe static footprint of custom JREs has been reduced in two main ways.■Link Time Optimization (LTO) has been implemented for ARMLTO reduces static footprint of JREs that use the minimal JVM and optimizesruntime performance on devices running ARM. For more information about theminimal JVM, see the JVM chapter in Oracle Java SE Embedded Developer's Guide.■Thumb-2 ISA mode is used for ARM VFP binariesFor ARM v7, and untested but should work on ARM v6 t2, Thumb-2 ISA modesupports Java Native Interface (JNI) for applications compiled in both ARM andThumb-2.Note:The use of Thumb-2 ISA means that ARM v6 is no longersupported as of this release; see Platforms and Requirements.1.2Runtime Performance ImprovementsThere are several JRE performance improvements at startup. For more information about Java Virtual Machines for embedded devices, see Oracle Java SE Embedded Developer's Guide.Specifically, the following enhancements have been implemented.■Client compiler (C1) inliningThe C1 inlining policy has been expanded by using profile information to improve performance in the minimal and client JVMs. This feature is a tech preview, and it is turned off by default.For information about how to enable C1 profiled inlining, see Oracle Java SEEmbedded Developer's Guide.■Class Data Sharing with custom classlistsClass Data Sharing (CDS) is an existing JDK feature that enables improved JVM startup times and reduced memory consumption. With CDS, you can preload and dump a set of class files to a shared-archive file. This prepared representation of the class files can be shared across multiple JVM processes. With this release of Oracle Java SE Embedded, you can generate your own classlist to a customlocation. For more information about using java command-line options to create and preload a custom classlist, see Oracle Java SE Embedded Developer's Guide.1.3Enhancements to Headful Application DevelopmentThe following changes enhance development of headful applications.■Support for Java FX components on the Freescale i.MX6 platform This release provides support for the JavaFX Base, Graphics, Controls and FXML components on the Freescale i.MX6 processor. For more information about JavaFX components, see Oracle Java SE Embedded Developer's Guide.■JavaFX multitouch input supportThis release supports touch events for multiple touch input points on the touch screen integrated into the Freescale i.MX6 Sabre device platform. There is touch support for up to 20 touch points, subject to the limits of the hardware and drivers used. Mouse events are synthesized from touch input. See the JavaFX Eventstutorial for how to handle touch points.Note that there is no support for multitouch gestures.■Swing/AWT support on X11 for headful development is supported on ARM v5 soft floatThe ARMv5 soft float port now includes Swing/AWT support on X11. See the Oracle Java SE Embedded System Requirements for a full list of devices that offer Swing/AWT support.1.4JSR 197 Bundled with Oracle Java SE EmbeddedThe JSR 197 specification API is equivalent to CLDC 1.0 GCF. The JSR 197 package is provided as a JAR file in the Oracle Java SE Embedded download bundle and can be manually copied into the JRE. For more information, see the section on the JSR 197 JAR in Oracle Java SE Embedded Developer's Guide.2Platforms and RequirementsSee Oracle Java SE Embedded System Requirements.Note that Oracle Java SE Embedded binaries are no longer provided for ARM v6 as of Release 8 Update 6, in order to take advantage of the size reduction and speed improvements that Thumb2 offers. Use JDK for ARM if you need ARM v6 support. 3Installing Oracle Java SE EmbeddedRefer to the Oracle Java SE Embedded README for installation instructions.Oracle Java SE Embedded 8 is a modular system that must be configured before launching by selecting components and creating a custom JRE to suit your device and applications, using the included jrecreate tool. See Oracle Java SE Developer's Guide. 4Known IssuesThis section describes known problems and issues in this release that are specific to Oracle Java SE Embedded. See also the Java SE 8 release notes for known issues, many of which also affect embedded platforms4.1Java SE API Documentation for the javax.crypto PackageBecause of a bug, the current Java SE API documentation for the javax.crypto package does not include compact profile information, but all classes and interfaces in the javax.crypto package are available with all compact profiles. For more information about compact profiles, see the Oracle Java SE Embedded Developer's Guide.4.2Raspberry Pi Power SupplyThe minimum power supply rating to use on the Raspberry Pi is 800mA. However, unless a higher-rated power supply is used, some problems can occur when the CPU or GPU are under heavy load. For example, USB ports can lose power or the device can suddenly reboot. We recommend the use of a 2A power supply.4.3Raspberry Pi Input EventsIf you run into problems with dropped input events, try reducing the USB bus speed. First, update the Raspberry Pi firmware:$ sudo apt-get update$ sudo apt-get install raspberrypi-bootloader --reinstallThen, open /boot/cmdline.txt in an editor. On the same line as the other options add dwc_otg.speed=1. Save the file, run sudo sync, and reboot.This option drops USB speeds from 480Mb/s to 12Mb/s, which resolves issues with a variety of USB devices on the Raspberry Pi.4.4JavaFX Generic BugsAll editions of JavaFX, including the components provided with Oracle Java SE Embedded, exhibit the issues listed at this site: .4.5AWT Graphics BugThis bug applies to AWT graphics on certain configurations when rendering is performed through the xrender pipeline. There are some platform X11 bugs that can cause empty or partially empty windows running AWT (not Swing) applications.As a workaround, xrender is disabled by default in Oracle Java SE Embedded.
