Datenbank Online-Event: Durch die Dornen zu den Sternen: Migration von Oracle nach Postgres

From: https://register.gotowebinar.com/register/6779806810633354254

Migration wie auch jede Veränderung ist die große Herausforderung. Wenn Unternehmen sich für die Migration von Oracle nach Postgres entscheiden, müssen diese gut vorbereitet sein. Organisatorisch müssen einige Aufgaben erledigt werden: – Neue Betriebskonzepte müssen erstellt werden – Personal soll sich mit der neuen Datenbank vertraut machen. Die Migration soll gut geplant und bestens vorbereitet werden. Als erstes sollen die möglichen Kandidaten für eine Migration nominiert werden. Die Migration der gesamten Oracle Datenbank macht wenig Sinn, da die interne Datenbank-Verwaltungsobjekte nicht migriert werden müssen. Relevant für eine Migration sind Kunden-spezifischen Daten, Anwendungen und User-Objekte. Am besten gruppiert man diese in logischen Einheiten, wie etwa ein Schema oder eine Anwendung und migriert diese nach Postgres. Danach sollen zu migrierenden Datenbank Objekte wie etwa Tabellen, Indexes, Funktionen, Packages und stored Procedures analysiert und angepasst werden. Folgende Herausforderungen sollen dabei bewältigt werden: – Erkennung und Beseitigung von Syntax Unterschieden – Konvertierung von Datentypen von Oracle nach Postgres – Lösung von Kompatibilitätsproblemen Wenn all diese Hürden genommen sind und Datenbank Objekte in der Postgres erstellt sind, kommt eine neue Aufgabe auf uns zu: Daten Migration. In diesem Webinar werden notwendige Schritte erläutert, die notwendig sind, eine Migration von Oracle nach Postgres, einfach und problemlos zu gestalten. Ich gebe einen Überblick über die Werkzeuge, die die Konvertierung von Objekten vereinfachen. Ich erkläre, wie Daten von Oracle nach Postgres unter der Voraussetzung des Minimal-Downtime-Ansatzes migriert werden können. In einer Demo spiele ich eine Migration vor. Dabei löse ich einige Probleme und anschließend migriere Daten.

DOAG DATENBANK ONLINE-EVENT: ORACLE 12C R2 RAC UPDATE NACH 19C – Ein Erfahrungsbericht

From:https://register.gotowebinar.com/register/5336635123429675275

Ein 8-Knoten Extended Distance RAC mit Oracle 12c Rel.2 auf SUSE Linux Enterprise Server 12 war als Nachfolger eines 11g RACs gerade fertig gestellt. Einige Datenbanken waren auch schon auf diesen neuen Cluster migriert. Da gab es auf Grund von Performance Problemen und der Zertifizierung einer Software die Anforderung, den RAC auf Oracle 19c zu aktualisieren. Unmittelbar nachdem das On-Premises Release der Oracle Datenbank Version 19c verfügbar war, wurde dieses Projekt angegangen. Das Patchen und auch Updaten von Oracle Datenbank Software ist in den letzten Jahren doch erheblich unkomplizierter geworden. Insbesondere da die Version 19c innerhalb der 12c Rel.2 Familie ja eigendlich das Sub-Release 12.2.0.3 darstellt sollten dabei doch keine größeren Probleme auftreten. In meinem Vortrag berichte ich vom Ablauf des Updates sowohl der Grid Infrastruktur als auch der Datenbanken von 12c Rel.2 auf 19c. Dabei zeige ich die diversen Hürden auf, die sich bei Schaffen der Installations- und Updatevoraussetzungen aber auch schon bei der Informationsbeschaffung in den Weg gestellt haben. So haben sich die Dokumente und damit die Informationen in My Oracle Support erst langsam entwickelt. Das Betriebssystem SLES 12 musste von SP2 auf SP3 aktualisiert werden. Auch die Oracle 12c Umgebung hat zuvor nach weiteren Patches verlangt. Welche Hürden noch zu nehmen waren und wie das Ziel erreicht wurde, wird im Rahmen des Vortrags erläutert werden.

Growing Momentum Around Oracle Blockchain Technology

 

From: https://www.aioug.org/events/growing-momentum-around-oracle-blockchain-technology

Oracle has released a new Blockchain Tables capability in Oracle Database and a significant update to the Oracle Blockchain Platform Cloud Service, leveraging the advantages of Oracle Cloud Infrastructure (OCI) Gen2 and new advancements by the Linux Foundation open source community in Hyperledger Fabric. As our blockchain customers are increasingly moving their applications into production and existing production customers are scaling up their deployments and ramping up their transaction volumes, this new release responds to their needs. Learn about the increased resilience and even higher availability, dynamic scale-up and scale-out to handle ever-growing workloads, stronger access controls for sharing confidential information, superior price/performance, greater decentralization capabilities for blockchain consortiums, and stronger audibility when using rich history database feature together with Oracle Database Blockchain Tables.  We’ll also discuss the latest solutions and customer use cases leveraging blockchain platform and blockchain tables.

AWS RDS: Read Oracle Traces from SQL*Plus

Hi all,

One more for AWS services. Let’s say you need to read tracefiles from RDS, hot to do it?

Here is an example on how to list and read those files:

SQL> select * from dba_directories;

OWNER DIRECTORY_NAME DIRECTORY_PATH ORIGIN_CON_ID

SYS ADUMP /rdsdbdata/log/audit 0

SYS DATA_PUMP_DIR /rdsdbdata/datapump 0
SYS OPATCH_INST_DIR /rdsdbbin/oracle/OPatch 0
SYS TMP /rdsdbdata/userdirs/01 0

7 rows selected.


SQL> select * from table (rdsadmin.rds_file_util.read_text_file( p_directory => 'BDUMP', p_filename => 'trace/CPROD1_s003_81573.trc'));

Checking Basic Licensing Info on a DB Server

Hi all!
So, I got a new client and started checking on his licensing and hardware. Then I realized how “non-standard” this is and Oracle should probably provide a better way to do it. So I decided to share a few things:

# Checking Oracle Version Installed:

[oracle@greporaSRV inventory]$ cd /opt/oraInventory/logs
[oracle@greporaSRV logs]$  grep "\- Database edition" installActions*.log
INFO: - Database edition : Standard Edition One (Create and configure a database)

# Checking number of Sockets

[root@greporaSRV ~]# cat /proc/cpuinfo | grep "physical id" | sort -u | wc -l
1

# Checking number of CPU Cores per Socket

[root@greporaSRV ~]# lscpu | grep 'socket'
Core(s) per socket:    4

AWS: ALTER SYSTEM and Managing SYS Objects in RDS

I’m very often managing services over EC2 and there are a few actions clients are often getting some issues to perform in RDS. So I decided to list here 5 of them:

Kill sessions:

begin
rdsadmin.rdsadmin_util.kill(
sid => &sid,
serial => &serial,
method => 'IMMEDIATE');
end;
/

Flush shared_pool or buffer_cache:

exec rdsadmin.rdsadmin_util.flush_shared_pool;
exec rdsadmin.rdsadmin_util.flush_buffer_cache;

Grant Privileges to SYS Objects

# Grant

begin
    rdsadmin.rdsadmin_util.grant_sys_object(
        p_obj_name  => 'V_$SESSION',
        p_grantee   => 'GREPORA',
        p_privilege => 'SELECT');
end;
/

# Grant with Grant Option

begin
    rdsadmin.rdsadmin_util.grant_sys_object(
        p_obj_name     => 'V_$SESSION',
        p_grantee      => 'GREPORA',
        p_privilege    => 'SELECT',
        p_grant_option => true);
end;
/

# Revoke

begin
    rdsadmin.rdsadmin_util.revoke_sys_object(
        p_obj_name  => 'V_$SESSION',
        p_revokee   => 'GREPORA',
        p_privilege => 'SELECT');
end;
/

 

Hope it Helps!

The team of speakers is awesome: Otavio Santana, Gonzalo Urday, Leandro Domingues and Igor de Paula. I’m glad to be among those exponents, sharing about Oracle NoSQL.

My session will be “Oracle NoSQL 101 for Oracle RDBMS DBAs“, where I’ll be sharing specifically from a RDBMS DBA perspective: What are the advantages of NoSQL in comparison to classic RDBMSs? How to integrate traditional data with new NoSQL structures? This session compares Oracle NoSQL with solutions for different proposes like Document, Columnar, Key-Value, Cache Systems e Graph databases, besides explore concepts like Data Integration and Oracle Maximum Availability (MAA) for Oracle NoSQL.

See you there!

AROUG 2019 Review

Hello all!

This year I had the privilege of attending Buenos Aires Groundbreakers edition for the fist time! This event is organized by AROUG. And here goes my thank you and my congratulations to specially to Sebástian and Rita for the great reception and event organization!

There I had the pleasure to talk a little bit over a few tips in my session: Tips and Tricks from over 20K hours DBA oncall

Besides those, I could also be in some other awesome sessions delivered by top speakers in the world, including (the ones I could attend): Markus Michalewicz, Ricardo Gonzalez, Rodrigo Jorge, Alberto Salazar, Facundo Grande, Anil Niar and Vicent Romero.

What I think? I can’t wait for the next one! Besides the great friends we met, it’s amazing to discuss such relevant topics with specialists on the area.

Thanks for everything, Buenos Aires and AROUG! See you soon!
