解决
打开/home/oracle/app/oracle/product/11.2.0/sysman/lib/ins_emagent.mk
找到如下内容后
$(SYSMANBIN)emdctl:
$(MK_EMAGENT_NMECTL)
进行修改为如下
$(SYSMANBIN)emdctl:
$(MK_EMAGENT_NMECTL) -lnnz11
再在root下执行
/home/oracle/app/oraInventory/orainstRoot.sh
/home/oracle/app/oracle/product/11.2.0/root.sh
如下
[root@oracle11g ~]# /home/oracle/app/oraInventory/orainstRoot.sh
Changing permissions of /home/oracle/app/oraInventory.
Adding read,write permissions for group.
Removing read,write,execute permissions for world.
Changing groupname of /home/oracle/app/oraInventory to oinstall.
The execution of the script is complete.
[root@oracle11g ~]# /home/oracle/app/oracle/product/11.2.0/root.sh
Check /home/oracle/app/oracle/product/11.2.0/install/root_oracle11g_2021-08-06_11-28-14.log for the output of root script
