ALTER_OPERATOR - change the definition of an operator
SYNOPSIS
ALTER OPERATOR name ( { left_type | NONE } , { right_type | NONE } ) OWNER TO new_owner
ALTER OPERATOR name ( { left_type | NONE } , { right_type | NONE } ) SET SCHEMA new_schema
DESCRIPTION
ALTER OPERATOR changes the definition of an operator. The only currently available functionality is to change the owner of the operator.
You must own the operator to use ALTER OPERATOR. To alter the owner, you must also be a direct or indirect member of the new owning role,
and that role must have CREATE privilege on the operator's schema. (These restrictions enforce that altering the owner doesn't do anything
you couldn't do by dropping and recreating the operator. However, a superuser can alter ownership of any operator anyway.)
PARAMETERS
name
The name (optionally schema-qualified) of an existing operator.
left_type
The data type of the operator's left operand; write NONE if the operator has no left operand.
right_type
The data type of the operator's right operand; write NONE if the operator has no right operand.
new_owner
The new owner of the operator.
new_schema
The new schema for the operator.
EXAMPLES
Change the owner of a custom operator a @@ b for type text:
ALTER OPERATOR @@ (text, text) OWNER TO joe;
COMPATIBILITY
There is no ALTER OPERATOR statement in the SQL standard.

I know that it is possible to login into the HMC console and view all the specs like, how much CPU/RAM every LPAR has.

I have made a simple script to find all programs that use a tcp wrapper, it will supply a reasonable default for my system if none is given.
