Timezone mismatch: The agentTZRegion value (US/Eastern) in
/u01/oracle/product/10.2.0/db_1/rac1_devdb1/sysman/config/emd.properties
does not match the current environment TZ setting(Asia/Chungking).
The dbconsole cannot run with this mismatch.
If US/Eastern is the correct timezone, set your timezone environment variable to US/Eastern and repeat the 'emctl start dbconsole' operation.
If US/Eastern is not the correct timezone, make sure that the timezone in your environment is correct, and then run the following command in your local Oracle Home: 'emctl resetTZ agent'
The output of this command will include detailed instructions to follow, to correct the mismatch.
解决办法如下：
rac1-> export TZ=PRC
rac1-> emctl config agent getTZ
