authentication failure

2018-04-12 Thread armand pirvu

Hi there

I have a process in place which runs several queries from one host to another 
one


All of a sudden I started noticing authentication failures

Ccing list.

Yes and worked fine until two days ago
I use .pgpass


So can you connect from wherever the process is run to the server 
manually? Something like:



psql -d birstab -U csidba -h some_server



I will also check and see if there are not too many hands in the cookie jar so 
to speak and things happen without being communicated

Yes I can that’s what is really puzzling me

[armandp@devweb2004 ~]$ /usr/pgsql-9.5/bin/psql -d birstdb -U csidba -h 
172.16.26.4
psql (9.5.12, server 9.5.8)
Type "help" for help.

birstdb=# 

It is almost like the authnetication stops working for whatever reason
I did check the .pgpass and all that and nothing chaged

Is there a possibility like say 70 processes try to authenticate in the same 
time and postgres authentication gets a bit lost ?


Thank you

From you previous post:

"It is almost like the authnetication stops working for whatever reason"

So to be clear the initial connections in the process go through, but at 
some point they start failing. Is that correct?


The timeout could be an issue. It would helpful to also see what 
max_connections setting is.




So if the server gets a bit oveloaded this could play a role ?

Yes correct initially they go through but at some point they start failing
Max_connections is set to 200 on the postgres server, but I did not notice any 
message about being maxed out connections wise
As a workaround for this very specific set of processes, until things get back 
in line so to speak, do you think from the devweb2004 (where processing is 
done) to devdb2004 (where the postgres database resides), should I just go from 
md5 to trusted ?

 From you previous post:

"It is almost like the authnetication stops working for whatever reason"

So to be clear the initial connections in the process go through, but at some 
point they start failing. Is that correct?

The timeout could be an issue. It would helpful to also see what 
max_connections setting is.


So if the server gets a bit oveloaded this could play a role ?

I would be inclined to raise the authentication_timeout first before 
setting the auth method to trust.


I would also set the below.:

https://www.postgresql.org/docs/10/static/runtime-config-logging.html#RUNTIME-CONFIG-LOGGING-WHAT

log_connections (boolean)
Causes each attempted connection to the server to be logged, as well as 
successful completion of client authentication. Only superusers can 
change this parameter at session start, and it cannot be changed at all 
within a session. The default is off.


log_disconnections (boolean)

That will give you a better idea of what is going on connection wise.

Will do so and report back

Also, in a previous post you mentioned:

"Yes and worked fine until two days ago"

Is the code under version control so you can see if anything changed two 
days ago?


If not, any recollections of significant events from that time period?



Many thanks
Armand

No change in the code
Only maybe the data volume and potentially the number of what we call events 
for which that runs
There was a talk to add some more functionality but never went through
However I will ask around to see if someone did not forget to say about a 
change put in place overnight (it happened before)

Thanks

Table schema inhancement

2018-04-12 Thread hmidi slim

Hi,
I have these tables:
price_per_occupation: id (integer), product_price_period_id(integer),
occupation_type(integer), price (numeric)

product_price_period; id(integer), product_id(integer), is_monday(boolean),
is_tuesday(boolean), is_wednesday(boolean), is_thursday(boolean),
is_friday(boolean), is_saturday(boolean), is_sunday(boolean),
price_period(daterange)

occupation_type: id(integer), name(varchar)

product: id(integer), name(varchar)

I run this query:

*select price_per_occupation.price, product_price_period.price_period,
occupation_type.name *

*from price_per_occupation inner join product_price_period on
product_price_period.id =
price_per_occupation.product_price_period_id*

*inner join occupation_type on occupation_type.id
 = price_per_occupation.occupation_type*

*inner join product on product.id  =
product_price_period.product_id*

*where product_price_period.price_period @> '[2018-07-22, 2018-07-23]'*
*and occupation_type.id  = 1*


This query returns all the products with an occupation_type = 1 and have
the period_price between 2018-07-22 and 2018-07-23.

However I need to verify if the boolean values verified.
E.g if is_monday = true the date corresponding to Monday will be eliminated
from the period.
if is_sunday = true and is_friday = true the dates corresponding to Sunday
and Friday will be eliminated from the period interval.
If I will choose all the products in the interval [2018-04-07,2018-04-14]
and is_monday = true and is_thursday= true
the date of monday is 09/04/2018 and date of friday is 13/04/2018.
I have to get all products contained in [2018-04-07,2018-04-08] U
[2018-04-10, 2018-04-12] U [2018-04-14, 2018-04-14]

In order to get the date of truthy columns I should execute a function
which contains a query like that:

select *
from generate_series(date '2018-04-07', date '2018-04-14', interval '1
day') the day
where extract ('dow', the_day) = 1


I'm face many problems with this schema;
I should verify the boolean values.
I should extract the corresponding dates based to the values.
I decompose the period into different periods then run the query to fetch
the products.

How can I enhance the query? or is there any proposition for the schema
table to enhance it?
