在 Linux 中运行 netca 和 netmgr 时出错

Question

When I am running netca and netmgr processes of Oracle in Linux I am getting the below mentioned error:

java.lang.NullPointerException
at oracle.ewt.lwAWT.BufferedApplet.<init>(Unknown Source)                                         
at oracle.net.ca.NetCA.<init>(NetCA.java:420)                                                     
at oracle.net.ca.NetCA.main(NetCA.java:406)

DISPLAY IS 192.9.200.14:0.0

How can I correct this?

Answer 1

Likely you have not exported your DISPLAY when logged in as oracle. Following works on my SUSE Linux Virtual Machine.

As root: xhost + su - oracle

As oracle: export DISPLAY=:0.0;
