Solve the Problem of Oracle 9iAS console errors

The Enterprise Manager Web Console of Oracle 9iAS is blank without any display and no error is reported.

Restarting the HTTP server has no effect on this phenomenon.

It is not helpful to stop Oracle services that run automatically in sequence.

Go to the command prompt and find the execution file of the Enterprise Manager Web console:

D:/ora9is/sysman/EMD/emctl

If you run this command directly, the Command help will be displayed, which will not be described here.

A. Check the emctl status and find that EM is started and normal. It indicates that EM itself is normal.

B. Use emctl stop to stop em. When emctl start is used to start emctl, A log4j error is reported. This is a debugging information error and should not affect the use of em.

C. When emctl listtartgets is used, the system prompts that the targets file information is incorrect.

In the Directory D:/ora9is/sysman/EMD/, the length of the targets. xml file is 0 bytes, And the cause is finally found.

Find a similar file and find that the node information list required by EM should be saved.

I solved this problem in a stupid way, so I don't want to talk about it.

Next, I want to verify that all the directories except the cold backup 9iAS are available. Is there any other way to retrieve targets. xml?
