I'm trying to run a rippled non-validator node.
I'm using an 32GB RAM C5 class instance in aws with an external volume - io1 storage with 10000 iops.
I had node reboot for patching and since then it seems fine but it returns
curl --data-binary '{"method": "fee","params": []}' -H 'content-type:text/plain;' http://:5005/
A normal response is like;
{"result":{"current_ledger_size":"68","current_queue_size":"0","drops":{"base_fee":"10","median_fee":"5000","minimum_fee":"10","open_ledger_fee":"10"},"expected_ledger_size":"150","ledger_current_index":51375387,"levels":{"median_level":"128000","minimum_level":"256","open_ledger_level":"256","reference_level":"256"},"max_queue_size":"3000","status":"success"}}
err;
{"result":{"error":"noNetwork","error_code":17,"error_message":"Not synced to Ripple network.","request":{"command":"fee"},"status":"error"}}
After reboot though I just get this Not synced error.
When I spin up a node from fresh it has to download 95GB of data at about 1 a day and it gets the same error while I'm waiting.
I'm wondering what I need to do to keep these nodes stable.

When I configure an item for log monitoring and then set a trigger for it, log monitoring doesn't work. I want to find the word ERRORand ORA-4030.
Steps to reproduce:
Install Zabbix 2.0.6.
Please have a look at the screenshot I have
attached for the configuration.
Create an item with the Zabbix agent
active.
Create a trigger based on that. Then the trigger says "Trigger just added. No
update so far". This remains like that.
When I check the latest data section, in the last check column is showing Never.

Please help me change my expression, let me know what I'm doing wrong here.
The trigger is correct, the real issue seems to be the data collection:
When I check the latest data section, in the last check column is
showing Never.
The log item is correctly set up as an Active Check, but in the Zabbix Agent configuration the corresponding ServerActive parameter is missing.
From the 2.0 documentation:
Make sure that in the agent configuration file:
'Hostname' parameter matches the host name in the frontend
Servers in the 'ServerActive' parameter are specified for the processing of
active checks
Modify your agent config to use both Server and ServerActive, pointing to the same ip:
Server=xx.xx.xx.xx
ServerActive=xx.xx.xx.xx
and restart the agent then check the latest data.
Additionally you can try to simulate the error with a simple echo "ERROR: ORA-4030 Simulated" >> /var/log/alert.log
I have in issue with pgpool2 and cannot figure out why!!!! my setup is as follows:
singe pgpool to do LB for me
master slave postgress
The issue is as follows, when i send read queries via the pgpool everything is fine, load get distributed between and master and salve.
but when im doing a query that writes to the database the pgpool again uses both slave and master and it yeilds error on queries sent to slave.
I have installed 96 on centos.

I have recently installed PostgreSQL on Ubuntu with the EnterpriseDB package. I can connect to the database locally, but I can't configure it because I can't find config files. I searched through entire hard drive and found only samples like pg_hba.conf.sample
Where are the PostgreSQL .conf files?
Or ask your database:
$ psql -U postgres -c 'SHOW config_file'
or, if logged in as the ubuntu user:
$ sudo -u postgres psql -c 'SHOW config_file'
Ubuntu 13.04 installed using software centre :
The location for mine is:
/etc/postgresql/9.1/main/postgresql.conf
Where are my postgres *.conf files?
Query the database with the sql query:
SHOW config_file;
The reason you may have trouble finding postgresql.conf is because it is owned by postgres, not root.
Here is where mine is on Fedora 17:
[root#defiant /]# ll /var/lib/pgsql/data/postgresql.conf
Notice it is owned by postgres:
-rw------- 1 postgres postgres 19332 Oct 14 09:38
/var/lib/pgsql/data/postgresql.conf
It has permission 600 which explains why you have a hard time finding it with a file search. The location of postgresql.conf will be different depending on what operating system you are using.
Here is the contents of mine:
# -----------------------------
# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
# name = value
#
# (The "=" is optional.) Whitespace may be used. Comments are introduced with
# "#" anywhere on a line. The complete list of parameter names and allowed
# values can be found in the PostgreSQL documentation.
#
# The commented-out settings shown in this file represent the default values.
# Re-commenting a setting is NOT sufficient to revert it to the default value;
# you need to reload the server.
#
# This file is read on server startup and when the server receives a SIGHUP
# signal. If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pg_ctl reload". Some
# parameters, which are marked below, require a server shutdown and restart to
# take effect.
#
# Any parameter can also be given as a command-line option to the server, e.g.,
# "postgres -c log_connections=on". Some parameters can be changed at run time
# with the "SET" SQL command.

Run
sudo updatedb
followed by
locate postgresql.conf
To get the location of the pg_hba.conf file, you can also query the database like
SHOW hba_file;
You should get something like
hba_file
---------------------------------
/var/lib/pgsql/data/pg_hba.conf
(1 row)
If you have just installed it, it is possible that locate doesn't help. In that case, the service should be running and you can run
ps aux | grep 'postgres *-D'
to see where the postgresql-master is loading the config files from.
On Mac (Postgres installed using brew) :
/usr/local/Cellar/postgresql/9.3.3>bin/postgres -D /usr/local/var/postgres/
Print pg_hba.conf file location:
su - postgres -c "psql -t -P format=unaligned -c 'show hba_file';"
Print postgresql.conf file location:
su - postgres -c "psql -t -P format=unaligned -c 'SHOW config_file';"
On Fedora 20
$ cd /var/lib/pgsql/data
$ ls -ltr *.conf
-rw-------. 1 postgres postgres 20453 Jan 18 23:22 postgresql.conf
-rw-------. 1 postgres postgres 1636 Jan 18 23:22 pg_ident.conf
-rw-------. 1 postgres postgres 4476 Jan 18 23:22 pg_hba.conf
On Mac OS X:
sudo find / -name postgresql.conf
You can find other conf files by the following command:
sudo find / -name pg\*.conf
Note: See usage using man:
man find
For CentOS 6 and 7 and postgresql 9.2 (and below, I suppose, possibly Fedora and Redhat as well):
/var/lib/pgsql/data
For CentOS 6 and 7 postgresql 9.3 or 9.4 (and above, I suppose):
/var/lib/pgsql/9.3/data
/var/lib/pgsql/9.4/data
For Ubuntu 14 and postgresql 9.3:
/etc/postgresql/9.3/main/postgresql.conf
The answer may be that you have not initialized the database yet. After installing postgres, but before initializing the database, the postgres*.sql files will be absent. After initializing the database the postgres*.sql files will appear. (Centos 6, Postgres 9.3 demonstrated here)
[root#localhost /]# yum -y install postgresql93 postgresql93-server

In Windows 10 pro:
C:\Program Files\PostgreSQL\11\data
As I don't have access to postgres account (so can't run SHOW config_file) and my postgres is installed on Windows, none of the answers helped me, so I'm sharing my file location for future Windows readers:
C:\Program Files\PostgreSQL\9.5\data
Besides the direct answer, you will probably want to check out the docs about Postgres config file locations.
In most cases: under $PGDATA, which is normally /var/lib/postgresql/data or something similar (at least it's the default path if you use Docker images).
I like this thread because it documents the default locations for various postgresql.conf files on various architectures...
However, I've also gotten in trouble by relying on those defaults on installations where they have specified alternate locations. One way to find out where a particular config file is by querying the database directly:
select * from pg_settings where name='config_file'
Drop the where clause to see all the settings, which can also be illuminating because it shows where data directories, pg_hba.conf, etc. are.
For Debian 9 I found mine using Franke Heikens answer - $ /etc/postgresql/9.6/main/postgresql.conf
If you have the postgres in a docker container, probably you are binding the .conf file, to find the .conf file you are using outside the docker, run docker inspect postgres11 or the postgres container name or id. That command returns a json, look for somethig like
"HostConfig": {
"Binds": [

If you execute SHOW config_file; and the result is in /var/lib/postgresql/data/postgresql.conf then you know the .conf file outside is in /home/my_user/postgres11/postgresql.conf, or the resulted in the property "Binds"

Win7, version 10 location:
C:\Program Files\PostgreSQL\10\postgresql.conf
In CentOS 7 with PostgreSQL 9.4 it's in the following directory:
/var/lib/pgsql/9.4/data
I can see it when I'm logged in as root.
on MacOS Mojave where I used brew install postgresql to install, I found it here
/usr/local/var/postgres/postgresql.conf
I got this using the following sql command cited in this response here:
psql -U postgres -c 'SHOW config_file'
For ubuntu 18/20, run the following command to locate your postgresql.conf file:
locate postgresql.conf
If locate is missing in your linux then run sudo apt-get install locate to install locate first.
I located it here:
/var/lib/pgsql/9.6/data/postgresql.conf
In ubuntu, you can find
/etc/postgresql/11/main/pg_hba.conf
// after change restart it otherwise it won't be work
service postgresql restart
If you followed the white paper put out by Amazon for installing Postgresql on AWS, which included creating a /data/ directory on a filesystem mounted on a separate EBS volume, then your postgresql.conf file is in /data/
From which I conclude the file is created during initialisation of the data directory, and resides in the root of the data dir. For a default install this appears to be /var/lib/pgsql/data, but not if you moved the data dir
My installation is not default, but you can go to directory the Postgres and find subdirectory \Data.
