Specifying Command Parameters as Keywords Instead of Single Letters
The use of single letter commands is deprecated. Oracle recommends that you use full command words with SRVCTL.
SRVCTL command parameters use full words instead of single letters, such as -multicastport and -subdomain.
To support backward compatibility, you can use a mix of single-letter parameters and new keyword parameters. New parameters introduced with keywords can be used with single letter parameters.
Note:
The use of single letter parameters are deprecated. Oracle recommends that you use the keyword parameters, so that you avoid using the same letter to implement different functionality, depending on the command.
You can obtain the single-letter equivalents, where applicable, by adding the -compatible parameter after the -help parameter.
