It's all good, I'm not upset or worried.
My job is to help build tools, and help people be successful using said tools.
Most of our users never touch the servers, they only connect to them from their
desktops. So that's the primary audience I'm trying to reach.
Also, I tend to open SQLcl (and SQL Developer) and never close it. Also for
Java, the first time you open a program, which will kick off the jvm, you'll
see a perf hit. The 2nd time you open it, not so much. So you in general can't
assume if it takes 4 seconds to open once, that I'll take 4 seconds to open the
2nd time.
The DB comes with Java, so it's already there for when you get to 12c and
higher installs.

Jeff,
The main traction against sqlci isn't the several seconds to start rather than
pretty much instant sqlplus (this becomes a factor when calling sqlplus
multiple times in a loop), nor the fact it's far superior to sql*plus, but the
red tape, security clearance, patching, etc, required to get new software
(especially the Java component) onto the all of the DB servers. That pretty
much nobody is using 12.2 in Production yet compounds it, so the red tape is
required. There's nothing you can do about this that time won't cure except
make the sqlci case increasingly compelling.
I use vi and sqlplus because they are guaranteed to be there. If I was a perm
DBA in a company long-term, I'd probably raise the paperwork to get it onto
every DB server purely for the automatic column size adjustments if nothing
else. Love that.

Slow to start? Maybe a second, or 3? If it's taking longer than that, please
let me know.
Java 8u50 or higher will be ok, which is about 2-2.5 years old?
It's a 20mb or so download, so takes less than a minute to install if you don't
have it. Less time than it takes maybe to setup rlwrap.esp if you're on
Windows.

Mladen,
What has that go to do with the original posters question?
If you are developing PL/SQL in SQL*Plus, you're probably not doing it
efficiently. SQL Developer is the better (free) tool for that, regardless of
platform.
SQLCI is great, but it's slow to start, requires a fairly recent Java release,
and only natively available from 12.2.
If you want Windows-like editing on a Linux SQL*Plus (or dgmgrl, rman or
whatever), use rlwrap.
regards
Neil Chandler.
Database Guy.

] it provides similar functionality to a windows CMD environment. You just
call the command you want to use via rlwrap
e.g. rlwrap sqlplus, or rlwrap dgmgrl
To keep thing simple, you can alias it
alias rsql='rlwrap sqlplus'
alias rdg='rlwrap dgmgrl'

Hi Neil,
Rlwrap is not an equivalent solution. The "rlwrap" trick breaks editing of
PL/SQL code, which can be annoying. If you write a multi-line PL/SQL snippet
and something goes wrong, "ed" will only return a part of the snippet. SQLCl
will do the right thing and give you back the entire procedure. It has a
primitive screen editor built into the code because arrow keys also work when
editing the history commands. Also, SQLCl has "REPEAT" command which turns your
SQLCl session into an instant monitor, if necessary. In addition to all that,
there is Jeff Smith, who has been doing an outstanding job with the product and
explaining it on this list. Jeff is extremely helpful and a very nice guy. And
no, I don't work for Oracle Corp. and I don't plan on working for Oracle
anytime soon.
