安装了Oracle之后,第一件事情就是想想怎么去连接,进而操作。SQL Developer是官方提供的强大工具,个人看来也是第一选择。
目前官网提供的最新版是4.0.1.14.48,下载下来之后,就跃跃欲试了。将下载下来的包解压,直接运行sqldeveloper.exe这个文件,选择了本地安装的JDK路径,之后却不幸的报错了,提示“unable to create an instance of the java virtual machine located at path”,具体界面如下:
解决办法如下:
找到sqldeveloper的配置目录,我的是XP,路径是:C:\Documents and Settings\Administrator\Application Data\sqldeveloper\
找到目录下的文件product.conf,我电脑上的绝对路径是:
C:\Documents and Settings\Administrator\Application Data\sqldeveloper\1.0.0.0.0\product.conf
打开该文件,将选项
AddVMOption -Xmx800m
改为: AddVMOption -Xmx512m
之后重新启动sqldeveloper.exe,成功运行。
