How to get Oracle Error Statements


Hi,

The best way to track the oracle errors is throug it's ORACLE Error log files. However, we do have one more manual mechanism to track all those ERROR Messages in Database using "SERVERERROR" DDL Triggers.

Please find the below steps to achieve this.

Step 1
======
SQL> GRANT ADMINISTER DATABASE TRIGGER TO <USERNAME>;

Step 2
======
create table oraerror (
id NUMBER,
log_date DATE,
log_usr VARCHAR2(30),
terminal VARCHAR2(50),
err_nr NUMBER(10),
err_msg VARCHAR2(4000),
stmt VARCHAR2(4000)
);

Step 3
======
create sequence oraerror_seq
start with 1
increment by 1
minvalue 1
nomaxvalue
nocache
nocycle;

Step 4
======
CREATE OR REPLACE TRIGGER after_error
 AFTER SERVERERROR ON DATABASE
 DECLARE
 pragma autonomous_transaction;
 id NUMBER;
 sql_text ORA_NAME_LIST_T;
 v_stmt VARCHAR2(4000);
 n NUMBER;
BEGIN
 SELECT oraerror_seq.nextval INTO id FROM dual;
 n := ora_sql_txt(sql_text);
 IF n >= 1
 THEN
 FOR i IN 1..n LOOP
 v_stmt := v_stmt || sql_text(i);
 END LOOP;
 END IF;

 FOR n IN 1..ora_server_error_depth LOOP   
   INSERT INTO oraerror VALUES (id, sysdate, ora_login_user, ora_client_ip_address, ora_server_error(n), ora_server_error_msg(n), v_stmt);
   COMMIT;
END LOOP;
 --
END after_error;

Test Case
=========
SQL> CREATE TABLE TESTING(T INT);
Table created.
SQL> SELECT FROM TESTING;
SELECT FROM TESTING
       *
ERROR at line 1:
ORA-00936: missing expression
SQL> SELECT * FROM ORAERROR;

ID LOG_DATE  LOG_USR
---------- --------- ------------------------------
TERMINAL       ERR_NR
-------------------------------------------------- ----------
ERR_MSG
--------------------------------------------------------------------------------
STMT
--------------------------------------------------------------------------------
1 23-JUL-12 SCOTT
 936
ORA-00936: missing expression
SELECT FROM TESTING

Pgpool Configuration & Failback

I would like to share the pgpool configuration, and it's failback mechanism in this post.

Hope it will be helpful to you in creating pgpool and it's failback setup.

Pgpool Installation & Configuration

1. Download the pgpool from below link(Latest version is 3.2.1).
    http://www.pgpool.net/mediawiki/index.php/Downloads


2. Untart the pgpool-II-3.2.1.tar.gz and goto pgpool-II-3.2.1 directory.

3. Install the pgpool by executing the below commands:

./configure ­­prefix=/opt/PostgreSQL92/ ­­--with­-pgsql­-includedir=/opt/PostgreSQL92/include/ --with­-pgsql­-libdir=/opt/PostgreSQL92/lib/ make make install 4. You can see the pgpool files in /opt/PostgreSQL92/bin location.
/opt/PostgreSQL92/bin $ ls clusterdb   droplang  pcp_attach_node  pcp_proc_count pcp_systemdb_info  pg_controldata  pgpool pg_test_fsync pltcl_loadmod  reindexdb createdb    dropuser  pcp_detach_node  pcp_proc_info createlang  ecpg      pcp_node_count   pcp_promote_node oid2name  pcp_pool_status  pcp_stop_pgpool  …

pgBucket - A new concurrent job scheduler

Hi All,

I'm so excited to announce about my first contribution tool for postgresql. I have been working with PostgreSQL from 2011 and I'm really impressed with such a nice database.

I started few projects in last 2 years like pgHawk[A beautiful report generator for Openwatch] , pgOwlt [CUI monitoring. It is still under development, incase you are interested to see what it is, attaching the image here for you ],


pgBucket [Which I'm gonna talk about] and learned a lot and lot about PostgreSQL/Linux internals.

Using pgBucket we can schedule jobs easily and we can also maintain them using it's CLI options. We can update/insert/delete jobs at online. And here is its architecture which gives you a basic idea about how it works.


Yeah, I know there are other good job schedulers available for PostgreSQL. I haven't tested them and not comparing them with this, as I implemented it in my way.
Features are: OS/DB jobsCron style sytaxOnline job modificationsRequired cli options

N-Node Mutlimaster Replication With Bucardo...!

Our team recently got  a problem, which is to solve the N-Node multi master replication in PostgreSQL.

We all know that, there are some other db engines like Postgres-XC which works in this way. But, we don't have any tool available in PostgreSQL, except Bucardo.

Bucardo is the nice solution for 2-Nodes. Is there a way we can exceed this limitation from 2 to N..?

As an initial step on this, I have done with 3 Nodes, which I believe, we can extend this upto N. { I might be wrong here.}

Please follow the below steps to set up the 1 - 1 multi master replication.

1. Follow the below steps to get all the pre-requisites for the Bucardo.

yum install perl-DBIx-Safe or apt-get install libdbix-safe-perl Install the below components from CPAN. DBI DBD::Pg Test::Simple boolean (Bucardo 5.0 and higher) Download the latest tarball from here. tar xvfz Bucardo-4.4.8.tar.gz cd Bucardo-4.4.8 perl Makefile.PL make sudo make install 2. We need to create plperl extension in db. For this, download…
