Editor to share with you what to do after the Oracle listener is hung up by the optimization master, I believe most people do not know much about it, so share this article for your reference. I hope you will gain a lot after reading this article. Let's learn about it together.

The solution after the Oracle listener is hung up by the optimization master:

An error occurred while starting the oracleorahome90tnslistener service, message:

Unable to start oracleorahome90tnslistener service on the local computer

Error 3: the system cannot find the specified path.

After looking up the information on the Internet, I found that the location of these files is generally determined by the ORACLE_HOME variable in the registry.

First take a look at the ORACLE_ home value under HKEY_LOACL_MACHINE/ SOFTWARE/ORACLE in the registry

If you don't have this value, you must add it.

The ORACLE_HOME value is generally the installation directory of ORACLE, such as c:oracleora90

(the other directory c:oracleadmin corresponds to ORACLE_BASE, the default location where your database is set up.)

Check again to see if the ORACLE_HOME network ADMIN listener.ora file exists.

The above documents are intact!

Then open the registry HKEY_LOACL_MACHINEsystemcurrentcontrolserservicesoracleorahome90tnslistener and find that the path imagepath is missing, so create a new string imagepath with the key value "C:oracleora90BINLSNRCTL.EXE"

Start the oracleorahome90tnslistener service again and report an error

The oracle listener won't open!

The error is 1053

Look for the problem again and again. Change the imagepath in the above registry to "C:oracleora90BIN nslsnr.exe".
