oracle TM lock, how-to find who forgot index on FK ?

oracle TM lock, how-to find who forgot index on FK ? published on Комментариев к записи oracle TM lock, how-to find who forgot index on FK ? нет

Lets do TM lock and find out what object should be indexed

create table tt ( id number ,fld varchar2(50) );
create table ttt ( id number ,id_tt number );
alter table tt add constraint pk_id primary key (id) ;
alter table ttt add foreign key ( id_tt ) references tt (id);
insert into tt select level ,rpad ('x',40) from dual connect by level <=100;
commit;

sess 1

 insert into ttt values ( 1,1);

sess 2

 delete from tt where id=1;

I use Tanel Poder sripts in this example
this one ( ashtop.sql )
and this one

oid.sql

hello, here how I dropped tempfile :

start with:

ALTER TABLESPACE temp  DROP TEMPFILE '+DATADG/p00pgp/tempfile/temp.340.882540285';
ALTER TABLESPACE temp  DROP TEMPFILE '+DATADG/p00pgp/tempfile/temp.339.882540283';

but when I try to drop datafiles I’ve got this error:
ORA-25152: TEMPFILE cannot be dropped at this time

helped this sript

SELECT   b.TABLESPACE
       , b.segfile#
       , b.segblk#
       , ROUND (  (  ( b.blocks * p.VALUE ) / 1024 / 1024 ), 2 ) size_mb

which helped me to find sessions using tempfile
sessions was idle, so I kill them, after that this command have no errors:

postgresql pgpool-II autofailover and failback

Hello, try to find a good material about how-to configure pgpool and found nothing, so I’ve decide to write my own article =))

I’m recommend to read previous articles:
How to install postgres
How to configure repmgr to manage standby databases
because I use those config in this scenario

So, lets start =)

First of all lest configure OS to match our needs ( I had to use RH 6 distributive )
1. configure passwordless ssh to all nodes from root and from postgres user
2. configure passwordless sudo to allow this commands:
add to /etc/sudoers

postgres ALL=(root) NOPASSWD: /sbin/ip
postgres ALL=(root) NOPASSWD: /sbin/arping
postgres ALL=(root) NOPASSWD: /sbin/ifconfig
postgres ALL=(root) NOPASSWD: /etc/init.d/postgresql-9.5

To allow passwordless pcp commands create this file in postgres and root users:

cat $HOME/.pcppass
*:*:pgpooladmin:q1
chmod 600 .pcppass

now lets configure pgpool

start with easiest part, configure pcp.conf
to do this run pg_md5 command with password as first argument:

[postgres@pg1 ~]$ pg_md5 q1
ff33f1b12213e021c2c4a888141953ba

result add to pcp.conf with format of username:pg_md5_pass

echo "pgpooladmin:ff33f1b12213e021c2c4a888141953ba" >> pcp.conf

I’m allow connect to pgpool from whole network, to archive this I’ve add this line to pool_hba.conf

host	all		all	10.10.10.0/24	md5

next session is to configure pgpool.conf
I’ve made it from pgpool.conf.sample-stream

diff pgpool.conf.sample-stream pgpool.conf

in my configuration I use trusted servers ( app servers ) you may leave it blank, also there was 3 node config ( for quorum) but in my test stand I use only two stands for one datacenter.

Key thig here is to keep first part of this file the same on all host ( where backend_hostname defenition is described )

copy config to second node:

scp  /etc/pgpool-II-95/* pg2:/etc/pgpool-II-95/

modify:
wd_hostname to second node
heartbeat_destination0 to first node
other_pgpool_hostname0 to first node

if you have any problems start pgpool in foreground mode ( also can be usefull to enable debug )
pgpool -f /etc/pgpool-II-95/pgpool.conf -n -d

usefull commands:
check node status
I use connect to VIP ip and port 9999

psql -U repmgr -d postgres -p 9999 -h 10.10.10.20 -c "show pool_nodes"
 node_id | hostname | port | status | lb_weight |  role   | select_cnt

For better result you should install database by this document
how-to install postgres database

i have 4 node config, 2 nodes in one datacenter and 2 in other

config will look like this:

DR1     DR2
DB01--->DB11
|       |
 \_DB02  \_DB12

create config file:

node1 /u01/postgres/9.5/main/conf/repmgr.conf

node=1
cluster=db_cluster
node_name=pg1
conninfo='host=pg01 user=repmgr dbname=postgres password=q1'
pg_bindir=/usr/pgsql-9.5/bin/
master_response_timeout=5
reconnect_attempts=2
reconnect_interval=2
failover=manual
promote_command='/usr/pgsql-9.5/bin/repmgr standby promote -f /u01/postgres/9.5/main/conf/repmgr.conf'
follow_command='/usr/pgsql-9.5/bin/repmgr standby follow -f /u01/postgres/9.5/main/conf/repmgr.conf'
use_replication_slots=1

node2 /u01/postgres/9.5/main/conf/repmgr.conf

node=2
cluster=db_cluster
node_name=pg2
conninfo='host=pg02 user=repmgr dbname=postgres password=q1'
pg_bindir=/usr/pgsql-9.5/bin/
master_response_timeout=5
reconnect_attempts=2
reconnect_interval=2
failover=manual
promote_command='/usr/pgsql-9.5/bin/repmgr standby promote -f /u01/postgres/9.5/main/conf/repmgr.conf'
follow_command='/usr/pgsql-9.5/bin/repmgr standby follow -f /u01/postgres/9.5/main/conf/repmgr.conf'
use_replication_slots=1

node3 /u01/postgres/9.5/main/conf/repmgr.conf

node=3
cluster=db_cluster
node_name=pg3
conninfo='host=pg03 user=repmgr dbname=postgres password=q1'
pg_bindir=/usr/pgsql-9.5/bin/
master_response_timeout=5
reconnect_attempts=2
reconnect_interval=2
failover=manual
promote_command='/usr/pgsql-9.5/bin/repmgr standby promote -f /u01/postgres/9.5/main/conf/repmgr.conf'
follow_command='/usr/pgsql-9.5/bin/repmgr standby follow -f /u01/postgres/9.5/main/conf/repmgr.conf'
use_replication_slots=1

node4 /u01/postgres/9.5/main/conf/repmgr.conf

node=4
cluster=db_cluster
node_name=pg4
conninfo='host=pg04 user=repmgr dbname=postgres password=q1'
pg_bindir=/usr/pgsql-9.5/bin/
master_response_timeout=5
reconnect_attempts=2
reconnect_interval=2
failover=manual
promote_command='/usr/pgsql-9.5/bin/repmgr standby promote -f /u01/postgres/9.5/main/conf/repmgr.conf'
follow_command='/usr/pgsql-9.5/bin/repmgr standby follow -f /u01/postgres/9.5/main/conf/repmgr.conf'
use_replication_slots=1
upstream_node=3

also we need to setup passwordless auth of repmgr user
create .pgpass file in postgres user home directory with 0600 premissions:

All nodes:

cat ~/.pgpass
*:*:*:repmgr:q1
chmod 600 ~/.pgpass

create repmgr user

createuser -s repmgr

also we need to allow repmgr to connect to database with replication role
add this lines to your pg_hba.conf file on all nodes:

cat /u01/postgres/9.5/main/conf/pg_hba.conf | tail -3

local   replication,postgres        repmgr                             trust
host    replicatoin,postgres        repmgr      127.0.0.1/32           trust
host    replication,postgres        repmgr      10.10.10.0/24        md5

Here I’m allowed to connect from all network, but if you want, you can limit this by certain machines.

Next step is configure repmgr

Create Master:

[postgres@pg1 ~]$  /usr/pgsql-9.5/bin/repmgr -f /u01/postgres/9.5/main/conf/repmgr.conf master register
[2016-12-05 19:06:36] [NOTICE] master node correctly registered for cluster db_cluster with id 1 (conninfo: host=pg1 user=repmgr dbname=postgres password=q1)

create standbys
on host pg2 and pg3: 

/usr/pgsql-9.5/bin/repmgr  -c -h pg1 -d postgres -U repmgr -D $PGDATA -f /u01/postgres/9.5/main/conf/repmgr.conf standby clone

start standby:

 pg_ctl start -o "-c config_file=/u01/postgres/9.5/main/conf/postgresql.conf"

and register standby:

/usr/pgsql-9.5/bin/repmgr -f /u01/postgres/9.5/main/conf/repmgr.conf standby register

create last standby ( which is going to be cascade standby ) and we are create this standby from PG3 database

/usr/pgsql-9.5/bin/repmgr  -c -h pg3 -d postgres -U repmgr -D $PGDATA -f /u01/postgres/9.5/main/conf/repmgr.conf standby clone

start and register database:

pg_ctl start -o "-c config_file=/u01/postgres/9.5/main/conf/postgresql.conf"
/usr/pgsql-9.5/bin/repmgr -f /u01/postgres/9.5/main/conf/repmgr.conf standby register

final result is 

postgres=# select * from repmgr_db_cluster.repl_nodes ;
 id |  type   | upstream_node_id |  cluster   | name |                            conninfo                            |   slot_name   | priority | active
----+---------+------------------+------------+------+----------------------------------------------------------------+---------------+----------+--------
  1 | master  |                  | db_cluster | pg1  | host=pg1 user=repmgr dbname=postgres password=xxxxxxxxxxxxxxxx | repmgr_slot_1 |      100 | t
  2 | standby |                1 | db_cluster | pg2  | host=pg2 user=repmgr dbname=postgres password=xxxxxxxxxxxxxxxx | repmgr_slot_2 |      100 | t
  3 | standby |                1 | db_cluster | pg3  | host=pg3 user=repmgr dbname=postgres password=xxxxxxxxxxxxxxxx | repmgr_slot_3 |      100 | t
  4 | standby |                3 | db_cluster | pg4  | host=pg4 user=repmgr dbname=postgres password=xxxxxxxxxxxxxxxx | repmgr_slot_4 |      100 | t

postgresql install how-to

postgresql install how-to published on 2 комментария к записи postgresql install how-to

I will split material of how-to install pgpool on several logical parts
here is the first one:

start install postgres with packages:

yum install  postgresql95-devel postgresql95 postgresql95-test postgresql95-libs postgresql95-server postgresql95-contrib pgbouncer.x86_64 repmgr95* pgpool-II-95 pgpool-II-95-extensions

for 9.6

yum install  postgresql96-devel postgresql96 postgresql96-test postgresql96-libs postgresql96-server postgresql96-contrib pgbouncer.x86_64 repmgr96*

for 10

yum install  postgresql10-devel postgresql10 postgresql10-test postgresql10-libs postgresql10-server postgresql10-contrib pgbouncer.x86_64

create directories and change home directory of postgres user:

mkdir /var/log/postgres
chown postgres: /var/log/postgres


usermod -m -d /u01 postgres
chown postgres: /u01 -R
su - postgres
cp /etc/skel/.bash* $HOME
mkdir -p /u01/postgres/main/pgdata/
mkdir -p /u01/postgres/main/pgdatats/
mkdir -p /u01/postgres/main/recovery
mkdir -p /u01/postgres/main/conf
mkdir /u01/postgres/main/recovery/backup
mkdir /u01/postgres/main/recovery/walarchive
mkdir /u01/postgres/main/recovery/dmp

configure bash_profile:

echo "export PGDATA=/u01/postgres/main/pgdata ">> ~/.bash_profile
echo "export PGTBS=/u01/postgres/main/pgdatats ">> ~/.bash_profile
echo "export PGCFG=/u01/postgres/main/conf ">> ~/.bash_profile

echo "export HISTTIMEFORMAT='%Y-%m-%d %H:%M:%S ' ">> ~/.bash_profile
echo "export HISTFILESIZE=9000 ">> ~/.bash_profile
echo "export PROMPT_COMMAND='history -a' ">> ~/.bash_profile
echo "export PS1='\[\e]0;\u@\h: \w\a\][\u@\h \W]$ ' ">> ~/.bash_profile

create dummy database:

/usr/pgsql-9.5/bin/initdb  --locale=ru_RU.utf8 --data-checksums

configure init scripts ( or systemd daemon ) to work with our external config directory:
RH6:

/etc/init.d/postgresql-9.5
PGDATA=/u01/postgres/main/pgdata
PGOPTS="-c config_file=/u01/postgres/main/conf/postgresql.conf"

RH7:

vim /usr/lib/systemd/system/postgresql-9.5.service
# Note: changing PGDATA will typically require adjusting SELinux
# Note: do not use a PGDATA pathname containing spaces, or you will
Environment=PGDATA=/u01/postgres/main/pgdata
Environment=PGCONF=/u01/postgres/main/conf
ExecStartPre=/usr/pgsql-10/bin/postgresql-10-check-db-dir ${PGDATA}
ExecStart=/usr/pgsql-10/bin/postmaster -D ${PGDATA} -c config_file=${PGCONF}/postgresql.conf

don’t forget about:

systemctl daemon-reload

Create starter database:

/usr/pgsql-9.5/bin/initdb --lc-collate=ru_RU.UTF8 --locale=en_US.UTF8 --encoding=UTF8
/usr/pgsql-9.5/bin/pg_ctl stop

Move config file /u01/postgres/main/conf/postgresql.conf to $PGCFG directory and modify it :

hba_file='/u01/postgres/main/conf/pg_hba.conf'

chown oracle: res_sqldb.ini
chown oracle: set_wait_classes.sh
chmod 777 set_wait_classes.sh
chmod 777 res_sqldb.ini
