Error while defining chain_step using dbms_scheduler.define_chain_step

Question

Hello,
I am trying to create a chain_job using dbms_scheduler in <Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit>
BEGIN
dbms_scheduler.create_chain (
chain_name => 'test_chain',
rule_set_name => NULL,
evaluation_interval => NULL,
comments => 'Test chain.');
END;
-- Chain Created Successfully
begin
dbms_scheduler.create_program (
program_name => 'test_program',
program_type => 'PLSQL_BLOCK',
program_action => 'BEGIN null; END;',
enabled => TRUE,
comments => 'Test program.');
end;
-- Program Created Successfully
begin
dbms_scheduler.define_chain_step (
chain_name => 'test_chain',
step_name => 'step_maximum_length_allowed',
program_name => 'test_program');
end;
Error at line 1
ORA-27465: invalid value STEP_MAXIMUM_LENGTH_ALLOWED for attribute step_name
ORA-06512: at "SYS.DBMS_ISCHED", line 3912
ORA-06512: at "SYS.DBMS_ISCHED", line 1452
ORA-06512: at "SYS.DBMS_SCHEDULER", line 1364
ORA-06512: at line 2
The step_name length I used above<'step_maximum_length_allowed'> is 27 characters.
If I use a step_name of length <= 24 characters, the define_chain_step works.
Question:
Does this error have to do with the maximum length allowed for step_name. If so, then the error raised should have reflected that.
Appreciate any help.
Thanks
Kumar

Thanks a lot damorgan for your reply :)
I have gone through the link you provided. I couldn't find any limits on step naming though.
Here is the question again with proper with proper formatting.
