The Oracle listener startup path is empty, and the service cannot be started.

Problem:

When you start the service on the control panel, the following error occurs:

Service: The OracleOraDb10g_home1TNSListener service cannot be started on the local computer.

Error 3: The specified path cannot be found.

Check the properties and find that the executable file path of OracleOraDb10g_home1TNSListener service is empty.

Solution:

Go to the Registry and modify ImagePath.

Start --> Run REGEDIT --> go to the Registry and find HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesOracleOraDb10g_home1TNSListener.

It is found that the key value of ImagePath is missing. Create a New expandable string value named ImagePath and edit the numeric data of the string as: Oracle installation path BINTNSLSNR.
