After extractingsqldeveloper-1.5.4.59.40.zipand executingsqldeveloper.exe,I received following error
---------------------------
Oracle SQL Developer
---------------------------
Unable to create an instance of the Java Virtual Machine
Located at path:
<SQLDEVELOPER>\jdk\jre\bin\client\jvm.dll
---------------------------
OK
---------------------------
Resolution for this error which works for me, as follow :-
Open ide.conf file from
<SQLDEVELOPER>/jdev/bin/ide.conf
or
<SQLDEVELOPER>\ide\bin\ide.conf
In this file, change this line :
AddVMOption -Xmx512M
by
AddVMOption -Xmx256M
Now, the executable is lauching correctly. No more errors with Java Virtual Machine.
Also check the diskspace where sqldeveloper is extracted and available RAM.
You may need to revert back in future if there is no more issue with original file's setting.
下载解压了Oracle SQL Developer工具,运行时,启动不了,报错信息如下:
---------------------------
Unable to create an instance of the Java Virtual Machine
Located at path:
<SQLDEVELOPER>\jdk\jre\bin\client\jvm.dll
---------------------------
是JVM参数设置的问题,我的解决方案如下:
<SQLDEVELOPER>\ide\bin\ide.conf
修改该文件,设置“AddVMOption -Xmx”参数,如下
AddVMOption -Xmx256M
然后就启动正常了。
另外,还有个设置方法如下,只是设置的地方不同,原理是一样的:
编辑文件:sqldeveloper\jdev\bin\sqldeveloper.conf 文件,
其中增加一行:
AddVMOption -Xmx256M
(若该设置已存在,请修改它的值)
