Oracle SQL Developer - Unable to create an instance of the Java Virtual Machine
来源:互联网 发布:如何谈恋爱 知乎 编辑:程序博客网 时间:2024/04/20 02:42
After extracting sqldeveloper-1.5.4.59.40.zip and executing sqldeveloper.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.
