Listener and Concurrent Managers are not coming up after clone in 11i

I performed 11i instance clone, adcfgclone went successful. When I tried to start the services the listener is not coming up. After troubleshooting sometime found that tnslsnr,tnsping and lsnrctl are missing. I thought the issue was with binaries. I again copied the apps binaries from source and now I made sure that all the binaries are copied successfully. I again ran adcfgclone and it went successful again. I tried to bring up the services, still the same issue. Strange, tnslsnr,tnsping and lsnrctl are missing again. The listener is coming up and hence Concurrent Manager also

Solution:


Copy  tnslsnr, tnsping and lsnrctl from source.

Stop all application services.

Run autoconfig (optional).

Try to bring the services.

 This time all the services were started successfully.

I looked at the adcgclone log, the file are missing after relinking tools (8.0.6) oracle home. I need to look at the relink log file to find the exact cause. I will take a look later after posting this blog.
