Introduction One of the advantage of Oracle Database Appliance is its fast deployment. Most often, the initial setup of a lite ODA (with a reimaging) only takes half a day, from unboxing until a first test database is available. Trust me, it’s hard to do better. For some reason, for example if you need to patch to the latest release and you have some intermediate patch to apply before, or if you plan to change…
Oracle Blockchain Tables With Oracle Database 20c/21c the new feature Oracle Blockchain Tables has been introduced. Blockchain Tables enable Oracle Database users to create tamper-resistant data management without distributing a ledger across multiple parties. Database security can be improved by using Blockchain Tables to avoid user fraud and administrator fraud as well. One of the main characteristics of Oracle Blockchain Tables is that you can only append data. Table rows are chained using a cryptographic…
Switching to Oracle Unified Auditing may produce lots of data when e.g. auditing activities of the SYS-user. I.e. according the documentation you can do the following to audit similarly as in traditional auditing with audit_sys_operations=TRUE: SQL> CREATE AUDIT POLICY TOPLEVEL_ACTIONS ACTIONS ALL ONLY TOPLEVEL; SQL> AUDIT POLICY TOPLEVEL_ACTIONS BY SYS; REMARK1: You may check the Blog on traditional SYS-auditing here REMARK2: Tests done in this Blog were done with Oracle 19.9. Auditing toplevel operations were…
Last month, Oracle released its new 21c version of the database documentation. At that time, I was looking for a quick mean to get all the books of this so-called 21c Innovation Release. I could remember I used a script to get them all in one run. Quick look at google, remembered me I used the one from Christian Antognini which hasn’t been refreshed for a while. In this blog, I will provide you the…
When a customer wanted to take the challenge to migrate an oracle database 9.2.0.6 (the prehistory in the Oracle world) to Oracle 19c using Oracle GodenGate, I saw more problems than add value for different reasons: Oracle 9.2.0.6 database is out of support (final 9.2 patch was Oracle 9.2.0.8). The customer Operating Systems was AIX 7.4 and only Oracle GoldenGate 11.1.1.1.2 for Oracle 9.2 for AIX 5.3 is available on https://edelivery.oracle.com. The Patch 13606038: ORACLE…
By Franck Pachot . This was initially posted to CERN Database blog on Wednesday, 12 September 2018 where it seems to be lost. Here is a copy thanks to web.archive.org Demo table I create a table for the demo. The CTAS gathers statistics (12c online statistics gathering) with one row and then I insert more rows: 10:33:56 SQL> create table DEMO as select rownum n from dual; Table DEMO created. 10:33:56 SQL> insert into DEMO…
I recently needed to configure bonding between 2 network cards on a customer side and I wanted trough this blog to share my findings and how I built it showing some traces. I will also do a short comparison of what is possible or not on the ODA.
By Franck Pachot . You may have read about Gradual Password Rollover usage from Mouhamadou Diaw and about some internals from Rodrigo Jorge. But it works only on 21c which is only in the cloud, for the moment, in Autonomous Database and DBaaS (but here I’ve encountered some problems apparently because of a bug when using SQL*Net native encryption). But your production is not yet in 21c anyway. However, here is how you can achieve…
By Franck Pachot . I have written a lot about SQL Plan Directives that appeared in 12c. They were used by default and, because of some side effects at the time of 12cR1 with legacy applications that were parsing too much, they have been disabled by default in 12cR2. Today, there are probably not used enough because of their bad reputation from those times. But for datawarehouses, they should be the default in my opinion….
Having recently reimaged and patched several ODA in version 19.8 and 19.9, I could see an issue with NTP. During my troubleshooting I could determine the root cause and find appropriate solution. Through this blog I would like to share my experience with you.
