figure
hold on
fplot(@sin)
fplot(@cos)

Once you have established a connection to Redis you can get and set values using the Jedis connection object:
Get
String value = jedis.get(myKey);
Set
jedis.put(myKey, "some value");
Generic example in a form of $a <=> $b matrix.
0 <=> 1; // -1 (left operand less than right, right is greater)
0 <=> 0; // 0 (operands are equal)
1 <=> 0; // 1 (left operand greater than right, left is greater)
1 <=> 1; // 0 (operands are equal)

The default configuration <C-b> is not the easiest to use. It'd be better to use something like ctrla. To do so, add this to tmux.conf
# remap prefix from 'C-b' to 'C-a'
unbind C-b
set-option -g prefix C-a
bind-key C-a send-prefix

To illustrate this, here is a function that has 3 different "wrong" behaviors
the parameter is completely stupid: we use a user-defined expression
the parameter has a typo: we use Oracle standard NO_DATA_FOUND error
another, but not handled case
Feel free to adapt it to your standa...
Each standard Oracle error is associated with an error number. It's important to anticipate what could go wrong in your code. Here for a connection to another database, it can be:
-28000 account is locked
-28001 password expired
-28002 grace period
-1017 wrong user / password
