[qsecofr@QLFI2]/QOpenSys/QIBM/ProdData/OPS# python3 -c 'import six;

1.10.0
/QOpenSys/QIBM/ProdData/OPS/Python3.4/lib/python3.4/site-packages/six.py


...and, pip3 is broken now. It doesn't work for me, getting the same error
as when I tried to pip3 install ibm_db

Bill - Any way to grab this whole conversation and bring it in to Ryver?

Since you’re both on the new community collaboration/communication
platform over on Ryver (and everyone else here in this list has been
invited), might this kind of interactive(ish) Q&A be more efficient and
effective within that interface?

Do you have an older version of six installed?

If you've gotten to a recent PTF level of the Python 3 runtime it will be
included by default.

What is the output of the following commands?

pip3 list | grep six

python3 -c 'import six; print(six.__version__); print(six.__file__);'

I did not have SI60567 install. I've installed it now. It added a
.whl
file to /QOpenSys/QIBM/ProdData/OPS/Python-pkgs/ibm_db, but only one
for
Python 2.7:

ibm_db-2.0.5.4-cp27-cp27m-os400_powerpc.whl

There is also an egg file, but that is for ibm_db v2.0.5.1 which I
think
is
what I already had installed. Is there a .whl file for ibm_db v
2.0.5.4
for Python 3?

connect/pconnect take implementation specific parameters, so they
aren't
in the PEP. We should probably document them somewhere. Here's the
function definitions from the ibm_db_dbi.py:

def connect(dsn=None, user='', password='', host='', database='',
conn_options=None):
def pconnect(dsn, user='', password='', host='', database='',
conn_options=None):

(Note, host is not supported on IBM i, since you have to specify
this
in
the RDB)


try this:


import ibm_db_dbi as dbi

conn = dbi.pconnect(dsn=None, database='*LOCAL', user=None,
password=None)


You can specify a DSN string like so:

dbi.pconnect("DATABASE=*LOCAL;UID=user;PWD=pass")


and this should be equivalent as above *LOCAL/None/None:

dbi.pconnect("DATABASE=*LOCAL")



Now that I'm looking at it again, it looks like I missed the
default
parameter for dsn on pconnect. Once that's there, you can do:

dbi.pconnect(database='*LOCAL', user=None, password=None)

(Already works on connect)



Make sure you're on the latest version of ibm_db. I'm not sure if
the
original shipped version of ibm_db_dbi actually worked. Since
2.0.5.1
it
should work, but I'd get to 2.0.5.4, which is shipped with
SI60567.

I'm trying ibm_db_dbi but can't figure out the pconnect
parameters.
Trying
to connect to the local database. Any pointers?

Hey John - where can I get some info on ibm_db? I tried out
the
itoolkit
on my IBM i today and was a bit disappointed in what I had
to do
to
access
the database. I'm guessing this is not going to be the
preferred
method
of
db access for Python. I'd appreciate pointers to any info
you
have
on
ibm_db for Python...

I agree with Kevin: Under normal circumstances, you should not
be
using ibm_db directly, but rather ibm_db_dbi, to get the
standard
Python database interface as laid out in PEP 249. If you're a
long-time Python user, you're probably already familiar with
this
interface. If not, I find the PEP is pretty good documentation
for
it.

To be completely honest, I have never had especially high
hopes
for
itoolkit, whether for accessing data or programs:

http://yips.idevcloud.com/wiki/index.php/XMLSERVICE/Python

The documentation for the underlying XMLSERVICE has been
around
for
quite some time now, as well as some of its wrappers in other
languages. It just seems fundamentally verbose and cumbersome,
by
Python standards. The Python version (judging by the
documentation
linked to above) is about as verbose as I was expecting. It
looks
almost as bulky as Java, but with a style reminiscent of Ruby.
Or
maybe JavaScript. (I only have a passing familiarity with
those
languages.) But I haven't given it a fair shake yet, so we'll
see.

If I do become a convert to IBM's Python (as opposed to the
third-party iSeriesPython which I'm using now), I may wind up
writing
my own wrapper for itoolkit, or my own fork of itoolkit.

To me, itoolkit seems to be mainly for calling native programs
and
service programs (mostly written by your own shop, mostly in
RPG),
or
IBM system APIs. Both of these uses are probably dwindling
niches,
as
more and more people write stored procedures and UDFs, and IBM
exposes
more and more system services to SQL. Eventually, you may be
able
to
just do everything with ibm_db_dbi. But I know our shop is far
from
that point.
