HomeDatabaseMysql TutorialUbuntu 14.04安装Oracle数据库管理软件SQL Developer记录

这一篇将在Ubuntu 14.04系统上安装Oracle数据库管理软件SQL Developer。

这是搭建Oracle开发环境日志的第二篇。

第一篇是:Ubuntu 14.04搭建PHP5+Apache2+Oracle环境

这一篇将在Ubuntu 14.04系统上安装Oracle数据库管理软件SQL Developer。

参考教程如下:

整个过程思路如下:

1.检查本地的jdk版本,如果过旧,则重新配置JDK环境

2.从oralce官方下载对应版本的sqldeveloper

3.解决sqldeveloper中文显示乱码

4.设置从命令行运行

安装过程:

1.检查本地jdk版本:

java -version 

java version "1.8.0_31"
Java(TM) SE Runtime Environment (build 1.8.0_31-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)

上面是我的系统上jdk版本,如果你的版本过低,强烈建议你升级jdk版本。否则下面安装最新版本的sqldeveloper过程中,启动会提示jdk版本过低。

重新配置jdk的教程:

目前oracle官网上给出的最新版本jdk是1.8,我们直接访问下面网址下载对应版本的jdk:

具体版本需要依据你的系统来定,例如我的系统是ubuntu X64 14.04,则下载jdk-8u31-linux-x64.tar.gz版本。切记不要下载rpm格式的安装包。我们是debian/ubuntu类型的系统,不支持rpm安装文件。

下载完成,解压该文件,然后检查你的系统是否有安装过jdk,也即检查你的系统有没有如下目录:

/usr/lib/jvm

如果没有,使用

sudo mkdir /usr/lib/jvm

创建目录。如果有,则直接将我们下载下来解压好的jdk文件夹整个复制到该目录下。

接下来,配置jdk的环境变量:

sudo vim ~/.profile

在该文件下面添加如下语句:

##For jdk1.8.0_31 PATH
export JAVA_HOME=/usr/lib/jvm/jdk1.8.0_31
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

JAVA_HOME常量的路径需要依据你的实际情况进行配置。

然后是使得该配置立即生效:

source ~/.profile

不出意外,此时你再次通过java -version命令查看你的jdk版本,就可以看到和我上面一致的输出了。

即使你的系统原来已经安装过了旧版本的jdk,也不必对原来的jdk进行处理。这一过程会自动将系统的jdk设置为最新安装的版本。

2.从oracle官方下载最新版本的oracle sqldeveloper安装包:

下载时,由于是ubuntu系统,在版本选择时,请选择Other Platform版本。

下载完成后解压,将其放置在用户的主目录下,例如我的是~/giantchan/。

然后通过命令行进入该文件夹:

cd ~/用户名/sqldeveloper


运行sqldeveloper.sh

sudo ./sqldeveloper.sh

在第一次启动时,会提示你输入jdk的路径。如何查看jdk的路径呢?

which javac

我们可以通过该命令打印出jdk的目录:

/usr/lib/jvm/jdk1.8.0_31/bin/javac

我们截取到jdk1.8.0_31/这里的路径,也即:

/usr/lib/jdk1.8.0_31

切记不要带“/bin/javac”,否则会报错,原因是sqldeveloper.sh会自动寻找该目录下的bin目录。如果加上bin目录的路径,就会重复。

如果不小心添加了bin目录,,我们可以到/home/用户名/.sqldeveloper/4.1.0(版本号)/product.conf

sudo vim /home/用户名/.sqldeveloper/4.1.0(版本号)/product.conf

找到如下语句,将后面的路径修改真正的jdk的路径:

SetJavaHome /usr/lib/jvm/jdk1.8.0_31

修改完成后保存退出。

重新运行./sqldeveloper.sh文件。此时发现可以正常启动sqldeveloper了。但是客户端的界面仍然会出现中文乱码。接下来第三步是解决乱码问题。

3.解决sqldeveloper在ubuntu下的乱码问题:

我们从网上下载任何一个中文的字体ttf文件(一定是要ttf)。

然后按照教程一步一步操作:

cd JAVA_HOME/jre/lib/fonts

sudo mkdir fallback

cd fallback

cp msyh.ttf ./        #此处的msyh.ttf是字体文件,此处使用的是微软雅黑,也可以用其他字体文件,只要支持中文即可。

sudo mkfontdir

sudo mkfontscale

然后重启sqldeveloper即可。至此,sqldeveloper已经成功安装到了ubuntu上,可以正常运行了。

4.从命令行运行:

我们可以在~/.bashrc文件中添加如下命令:

#oracle sqldeveloper
alias sqld='cd ~/用户名/sqldeveloper && sudo ./sqldeveloper.sh'

然后通过source命令使设置立即生效:

source ~/.bashrc

以后就可以通过sqld命令来启动sqldeveloper软件了。

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
