AIX中检查的JVM是32位还是64位的命令

lslpp -l | grep -i Java

  Java14.sdk 1.4.2.75 COMMITTED Java SDK 32位

  Java5_64.sdk 5.0.0.50 COMMITTED Java SDK 64位

 

rpm -qa | grep -i Java

 

要检查磁盘上实际有什么：
 

ls -la / usr | grep -i Java

drwxr-xr-x 7 bin bin 4096 2007年2月9日java14

drwxr-xr-x 7 bin bin 256 2006年5月17日java5_64

 

要查看路径中的内容：
 

which java

/ usr / java5_64 / bin / java

 

要获取其版本详细信息：
