By Franck Pachot . 12.1 introduced Unified Auditing where you define policies and then enable them. As with the traditional audit, you enable them for all users or for specific users. The unified auditing adds a syntax to audit all users except some listed ones. 12.2 adds a syntax to audit a group of users, defined by the role granted.…
By Franck Pachot . Updated June 5th When reading about new version numbering in SQL Developer, I took the risk to change the title and guess the future version number for Oracle Database: Oracle 17.3 for the July (Q3) of 2017. Of course, this is just a guess. Updated June 10th Confirming the previous guess, we start to see some…
By Franck Pachot . When cloning a PDB from a remote CDB you need to define a database link to be used in the CREATE PLUGGABLE DATABASE … FROM …@… command. The documentation is not completely clear about the privileges required on the source for the user defined in the database link, so here are the different possibilities. Remote clone…
By Franck Pachot . In a previous post, I explained that Cross-PDB DML, executing an update/delete/insert with the CONTAINERS() clause, seems to be implemented with implicit database links. Connecting through a database link requires a password and this blog post is about an error you may encounter: ORA-01017: invalid username/password; logon denied This blog post also explains a consequence of…
By Franck Pachot . Since 12cR2 is out, we give our 12c new feature workshop with hands-on exercises on 12.1 and 12.2 releases. When I gave it last month, I had a small problem when doing demos: sometimes the connections as sysdba failed with “ORA-01017: invalid username/password”. It was at random, about one every 5 login attempts and I was…
By Franck Pachot . Multitenant has been introduced in 12.1.0.1 with the goal to share resources but isolate data. However, having all PDBs in the same root may be convenient to manipulate data in multiple PDBs. In the first patchset, 12.1.0.2, a way to query cross-container has been introduced for the CDB administrator to see data in other containers. In…
This week I needed to install Oracle Grid Infrastructure 12c release 1 in a SLES 12 SP1 environment. Everything worked fine until I ran the root.sh at the end of the installation. Here’s a quick description of the problem and the workaround. The root.sh script ran into error and the installation was completely unsuccessfull: oracle:/u00/app/grid/12.1.0.2 # /u00/app/grid/12.1.0.2/root.sh Performing root user…
By Franck Pachot . If you are in multitenant, you probably already felt the desire to open the PDB$SEED in READ WRITE mode. Can you open PDB$SEED read write yourseld? Yes and No. Should you open PDB$SEED read write yourself? Yes and No. How to run upgrade scripts that need to write to PDB$SEED? catcon.pl In 12.1 you have no…
By Franck Pachot . The title sounds weird because Data Guard synchronisation is based on the redo stream, so it makes no sense to do nologging operations on the primary. And this is the reason why we set FORCE LOGGING on a Data Guard configuration. However, to lower the downtime of a migration done with Data Pump, you may want…
By Franck Pachot . I had a recent question about the following mention from the 12cR2 Multitenant book, about Partial PDB backups: . Here is an example in 12.2 with local undo to illustrate the answer, which may help to understand what is a partial PDB backup. Of course, since 12cR1 you can backup PDB individually, without the CDB$ROOT, in…
The Oracle 12.2.0.1 version has some interesting new features concerning tables or indexes. The first new feature is about the online table move. In 12.2 version Oracle offers now the possibility to move non-partitioned tables without blocking any DML operations. To realise this operation, we must use the ONLINE keyword and/or the UPDATE_INDEXES clause. If you remember, in the previous Oracle…
By Franck Pachot . Do you know the RMAN Recovery advisor? It detects the problems, and then you: RMAN> list failure; RMAN> advise failure; RMAN> repair failure; You need to have a failure detected. You can run Health Check if it was not detected automatically (see https://www.dbi-services.com/blog/oracle-12c-rman-list-failure-does-not-show-any-failure-even-if-there-is-one/). In 12.2 you can run the repair directly, by specifying what you want…
