Oracle Database Discussions

Hi,

Could anybody tell me how could I check where is an issue in the Oracle Grid ?

Oracle EM Grid Control is working (on one computer)
Oracle Agent is working on another computer, but the Grid cannot see the agent working ( or the agent cannot register to the grid control )

[oracle@PC1 agent]$ emctl status agent
