Netdrms 9.1.1¶

Posgres 9.4.13¶

Install additional modules¶

We need dblink for triggers between db

root@sdo1:~# cd /usr/share/postgresql/9.4/extension
root@sdo1:/usr/share/postgresql/9.4/extension# ls -al  dblink--1.1.sql
-rw-r--r-- 1 root root 5831 Aug 10 14:53 dblink--1.1.sql

ias_sdo¶

root@sdo1:/usr/share/postgresql/9.4/extension# psql ias_sdo -p5432 -U postgres < dblink--1.1.sql
Use "CREATE EXTENSION dblink" to load this file.
root@sdo1:/usr/share/postgresql/9.4/extension# 
root@sdo1:/usr/share/postgresql/9.4/extension# 
root@sdo1:/usr/share/postgresql/9.4/extension# 
root@sdo1:/usr/share/postgresql/9.4/extension# psql ias_sdo -U postgres 
psql (9.4.13)
Type "help" for help.

ias_sdo=# CREATE EXTENSION dblink ;
ERROR:  extension "dblink" already exists
ias_sdo=# \q

Seems ok !

ias_sdo_sums¶

root@sdo1:/usr/share/postgresql/9.4/extension# psql ias_sdo_sums -p5434 -U postgres < dblink--1.1.sql 
Use "CREATE EXTENSION dblink" to load this file.
root@sdo1:/usr/share/postgresql/9.4/extension# psql ias_sdo_sums -p5434 -U postgres 
psql (9.4.13)
Type "help" for help.

ias_sdo_sums=#  CREATE EXTENSION dblink ;
ERROR:  extension "dblink" already exists
ias_sdo_sums=# \q

Seems ok too !

ias_sdo_monitor¶

root@sdo1:/usr/share/postgresql/9.4/extension# psql ias_sdo_monitor -p5436 -U postgres < dblink--1.1.sql 
Use "CREATE EXTENSION dblink" to load this file.
root@sdo1:/usr/share/postgresql/9.4/extension# psql ias_sdo_monitor -p5436 -U postgres
psql (9.4.13)
Type "help" for help.

ias_sdo_monitor=# CREATE EXTENSION dblink ;
ERROR:  extension "dblink" already exists

Ok too!

Ingest last dumps from sdo1¶

postgres@sdo1:~/dumps$ gunzip < ias_sdo_sums_2017-09-28.gz | psql ias_sdo_sums  -p5434 -U postgres

postgres@sdo1:~/dumps$ gunzip < ias_sdo_2017-09-28.gz | psql ias_sdo -p5432 -U postgres

postgres@sdo1:~/dumps$ gunzip < ias_sdo_monitor_2017-09-28.gz | psql ias_sdo_monitor -p5436 -U postgres

Creation of missing tables & functions¶

TABLE drms.ingested_sunums

--When a client ingests a Slony log, each SUNUM of each data series record is copied
-- into this table. The client can use this table of SUNUMs to prefetch SUs from the
-- providing site. This SQL is ingested as the pg_user database user, the same
-- user that will be ingesting Slony logs and prefetching SUs, so permissions on
-- this table will be correct without having to execute a GRANT statement.
--
-- The namespace drms is required, and is created by NetDRMS.sql during the
-- NetDRMS installation process.
--

DROP TABLE IF EXISTS drms.ingested_sunums;
CREATE TABLE drms.ingested_sunums (sunum bigint PRIMARY KEY, starttime timestamp with time zone NOT NULL);
CREATE INDEX ingested_sunums_starttime ON drms.ingested_sunums(starttime);

FUNCTION drms.capturesunum
--
-- For each table under replication, a trigger is created that calls this function, which
-- then copies SUNUMs into the underlying table, drms.ingested_sunums.
--
-- drms.ingested_sunums may not exist (older NetDRMSs did not receive the SQL to create
-- this table). If this table does not exist, then this function is a no-op.
--

CREATE OR REPLACE FUNCTION drms.capturesunum() RETURNS TRIGGER AS
$capturesunumtrig$
BEGIN
    IF EXISTS (SELECT n.nspname, c.relname FROM pg_class c JOIN pg_namespace n ON n.oid = c.relnamespace WHERE n.nspname = 'drms' AND c.relname = 'ingested_sunums') THEN
      IF (TG_OP='INSERT' AND new.sunum > 0) THEN
        IF EXISTS (SELECT 1 FROM drms.ingested_sunums WHERE sunum = new.sunum) THEN
          RETURN NULL;
        END IF;
        INSERT INTO drms.ingested_sunums (sunum, starttime) VALUES (new.sunum, clock_timestamp());
      END IF;
    END IF;

  RETURN NEW;
END
$capturesunumtrig$ LANGUAGE plpgsql;

Add a trigger on every hmi table like this to use the function:

CREATE TRIGGER capturesunumtrig AFTER INSERT ON hmi.bharp_720s FOR EACH ROW EXECUTE PROCEDURE drms.capturesunum();

-- TABLE drms.ingested_sunums
--
-- When a client ingests a Slony log, each SUNUM of each data series record is copied
-- into this table. The client can use this table of SUNUMs to prefetch SUs from the
-- providing site. This SQL is ingested as the pg_user database user, the same
-- user that will be ingesting Slony logs and prefetching SUs, so permissions on
-- this table will be correct without having to execute a GRANT statement.
--
-- The namespace drms is required, and is created by NetDRMS.sql during the
-- NetDRMS installation process.

CREATE TRIGGER capturesunumtrig AFTER INSERT ON hmi.bharp_720s FOR EACH ROW EXECUTE PROCEDURE drms.capturesunum();

NOT for aia.lev1 series because we are taking 1/5 data we don't want everything

Create shadow & speed up the usage of aia.lev1 table¶

postgresql-plperl¶

In order to run createshadow we need postgresql-plperl

apt-get install postgresql-plperl 

Install language plperl¶

Install plperl within postgres

createlang -p5432 -U postgres plperlu ias_sdo

Create function updateshadow()¶

Create function updateshadow()

psql ias_sdo -p5432 -f /usr/local/netdrms_current/base/drms/libs/pg/updateshadow.sql

So now we are able to launch createshadow()

createshadow series=aia.lev1

Get data from JSOC¶

Create readonly user¶

production@sdo1:/usr/local/netdrms_current$ psql ias_sdo_sums -p5434 -U postgres 
psql (9.4.13)
Type "help" for help.

ias_sdo_sums=# CREATE USER readonlyuser;
CREATE ROLE
ias_sdo_sums=# GRANT CONNECT ON DATABASE ias_sdo_sums To readonlyuser ; 
GRANT

Launch rsums-client.py¶

python3 base/drms/replication/subscribe_series/rsums-clientd.py --loglevel=debug &

NetDrms 9.1.1 FAQ¶

rsumsd.py keep crashing¶

Error message :
If you 've got sthg like in rslog_20171204.txt (for exemple)

2017-12-04 14:35:56 - DEBUG - rsumsd.py:423 - Exiting TerminationHandler.
2017-12-04 14:35:56 - ERROR - rsumsd.py:441 - (get) No SU-table record exists for SU 995061214.
2017-12-04 14:35:56 - INFO - rsumsd.py:429 - Exiting with return status 15.

Workaround :

1) Delete from ingested_sunums table
ias_sdo=# select * from drms.ingested_sunums where sunum=995061214;
sunum | starttime
-----------+-------------------------------
995061214 | 2017-11-30 18:02:18.085994+01
(1 row)

ias_sdo=# delete from drms.ingested_sunums where sunum=995061214;
DELETE 1

2)Delete from rs.requests

ias_sdo=# select * from drms.rs_requests where sunums like '%995061214%' ;
ias_sdo=# delete from drms.rs_requests where sunums like '%995061214%' ;
DELETE 132

3) Restart daemons sumsd.py , rsumsd.py, rsums-clientd.py as production
