问题描述
Weblogic应用启动后，在某个节点，root用户切换到weblogic用户报如下错误：
bash: fork: Resource temporarily unavailable
问题分析：
从错误的字面意思可以看到临时资源不足
查看内存充足
查看用户进程
ps -ef | wc –l
ps ux | wc -l
ulimit -u
查看用户限制
su – weblogic(报错，无需理会等会儿)
ulimit –a

解决方法
修改操作系统的资源配置：
su – root
vi /etc/security/limits.conf
增加如下内容
weblogic soft nproc 2047
weblogic hard nproc 16384
weblogic soft nofile 1024
weblogic hard nofile 65536
su – weblogic(此时应该不会报错了)
ulimit –a
