嘗試使用 update-java-alternatives 切換到 Java 6 後如何在 Ubuntu 中修復 Java
我嘗試使用“update-java-alternatives”命令從 Java 5 切換到 Java 6,如本頁所述:https ://help.ubuntu.com/community/Java
但是後來當我嘗試執行java時出現以下錯誤:
root@webserver:~# java Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine.
我還嘗試使用“apt-get”重新安裝 java 二進製文件,但我沒有成功重新安裝它。我想發布“apt-get”錯誤,但不幸的是我不知道如何用英語而不是德語列印錯誤消息。
我的系統是 Ubuntu 8.04 ROOT 伺服器。
這是再次安裝 Java 6 的(Google翻譯的)英文文本:
root@server:~# apt-get install sun-java6-jdk Reading package lists ... Ready Dependency tree Reading state information ... Ready sun-java6-jdk is already the newest version. sun-java6-jdk set to manually installed. 0 upgraded, 0 newly installed, 0 to remove and 86 not upgraded. 1 not fully installed or removed. After this operation, 0B of additional disk space will be used. Set up a sun-java6-bin (6-03-0ubuntu2) ... Could not create the Java virtual machine. dpkg: error processing sun-java6-bin (- configure): Subprocess post-installation script returned error exit status 1 Errors were encountered while processing: sun-java6-bin E: Sub-process / usr / bin / dpkg returned an error code (1)
我希望這可以幫助你幫助我。
Java 說它沒有足夠的記憶體。您是否嘗試使用記憶體限制參數執行它,例如
java -Xms64m -Xmx512m
(將值調整為伺服器可用記憶體)?
我建議再次嘗試安裝,這樣:
apt-get --reinstall install sun-java6-jdk
這將完全重新安裝軟體,而不是嘗試配置已經存在的軟體。
