问题
I've just installed SQL Developer 4.1.1 64-bit on a Windows Vista machine, in directory c:\sqldeveloper.
My Java installation is in c:\program files\java and I have two sub- directories:
c:\program files\java\jdk1.8.0_31
c:\program files\java\jdk1.8.0_25
I have modified the jdf.conf and sqldeveloper.conf files in the c/sqldeveloper/sqldeveloper/bin directory. jdf.conf was empty and I added the following line:
SetJavaHome c:\program files\java\jdk1.8.0_31
sqldeveloper.conf:
#SetJavaHome ../../jdk <===== This is what is was
SetJavaHome c:/program files/java/jdk1.8.0_31 <======= I changed it to this
I even moved the missing file "msvcr100.dll" it was asking for to the c/sqldeveloper/sqldeveloper/bin directory.
I get the following error messages:
- This application has failed to start because msvcr100.dll was not found. Re-installing this application may fix this problem
- Unable to launch the java virtual machine located at path c:\sqldeveloper\jdk\jre\bin\server\jvm.dll
The file msvcr100.dll is in the Java directory c:/program files/java/jdk1.8.0_31/bin.
The file jvm.dll is in the Java directory
c:/program files/java/jdk1.8.0_31/bin/jre/bin/server.
I modified product.conf:
#SetJavaHome /path/jdk <===== This is what it was
SetJavaHome C:/Program Files/Java/jdk1.8.0_31 <====== This is what I changed it to
I have a copy of msvcr100.dll in sqldeveloper/sqldeveloper/bin folder and in the c:/program files/java/jdk1.8.0_31/bin folder.
To run SQL Developer I click on sqldeveloper.exe in the c:/sqldeveloper/sqldeveloper/bin directory.
I am running it the correct way?
回答1:
I ran in to the same problem myself, trying to run SQL Developer 4.1.1 64-bit with JDK on a Windows Server 2008. I've installed SQL Developer many times over the years from 1.x to 4.1.1 and never encountered this until now.
I solved it by copying the MSVCR100.dll file from sqldeveloper\jdk\jre\bin to the sqldeveloper\sqldeveloper\bin folder.
Update 3/18/2017:
In downloading the latest version from Oracle's website, I found this in the installation notes which confirms and explains the issue:
Note: the Windows EXE requires a MSVCR100.dll to run. Most computers will already have this file and in the Windows PATH. However, if the first copy of the file found by the EXE is a 32-bit copy of the DLL, then SQL Developer will fail to start. You can fix this by copying a 64-bit version of the DLL into the BIN directory or updating your OS PATH such that a 64 bit copy of the DLL is found first.
回答2:
Only create the directory /sqldeveloper/jdk/bin and copy The file msvcr100.dll is in the directory.
Then /bin don't exist is in the /sqldeveloper/jdk
回答3:
You need to copy the msvcr100.dll file from sqldeveloper/jdk/jre/bin/msvcr100.dll to sqldeveloper/sqldeveloper/bin/. Then just open SQL Developer again.
回答4:
You only need to create the directory \bin in sqldeveloper \sqldeveloper\jdk\bin and copy the msvcr100.dll file in this new directory.
回答5:
I have faced this similar issue on my local system.
I have solved this issue by copying bin directory from insatallation_directory/jdk/jre to insatallation_directory/jdk/
