What to do if you get the above error when you try to install Oracle SE2 (did not test if the same issue is there with EE, but probably it is) in silent mode?: ./runInstaller oracle.install.option=INSTALL_DB_SWONLY \ ORACLE_BASE=/u01/app/oracle/ \ ORACLE_HOME=/u01/app/oracle/product/12.1.0/db_2_4/ \ UNIX_GROUP_NAME=oinstall \ oracle.install.db.DBA_GROUP=dba \ oracle.install.db.OPER_GROUP=dba \ oracle.install.db.BACKUPDBA_GROUP=dba \ oracle.install.db.DGDBA_GROUP=dba \ oracle.install.db.KMDBA_GROUP=dba \ FROM_LOCATION=../stage/products.xml \ INVENTORY_LOCATION=/u01/app/oracle/oraInventory/ \ SELECTED_LANGUAGES=en \ oracle.install.db.InstallEdition=SE2 \ DECLINE_SECURITY_UPDATES=true -silent -ignoreSysPrereqs -ignorePrereq -waitForCompletion You already checked my oracle support and verified that…

Configure a Kerberos Client and Alfresco as a Kerberized application

By | Application integration & Middleware | No Comments

In the previous blog, I described How to install and manage a Kerberos Server but that’s useless if there are no clients and if no application have been kerberized! That’s why in this blog I will explain in the first part how to install a kerberos client in linux. The second part will be dedicated to the configuration of a browser to use Kerberos tickets and the last part will explain how to configure a…

How to install and manage a Kerberos Server

By | Application integration & Middleware | 5 Comments

For some time now, I have been working on how to set up a Single Sign-On (SSO) solution in my company. As a big fan of Open Source solutions, I have obviously proposed the implementation of a solution based on Kerberos. What I mean by that is a solution based on the true Kerberos, i. e. MIT Kerberos. Indeed, Kerberos was originally a research project at the Massachusetts Institute for Technology (MIT) in the early…

Oracle Database 12c new features: segregation of duties with new administrative roles

By | Database management | No Comments

Starting with Oracle Database 12C Release 1 a set of new administrative privileges that are more task oriented are available.

Before Oracle 12c it was needed to have the SYSDBA privilege to make a backup, to monitor the Data Guard status or to administrate some features of Oracle Transparent Data Encryption. Starting with this new Oracle release it is not anymore the case. We can grant limited administrative privileges to operate an Oracle 12c database.

Errors while installing Oracle Database Vault on Oracle 11.2.0.3

By | Database management | 2 Comments

During one of my last consulting missions, I had to install Oracle Database Vault on an existing Oracle environment. It clearly was not a straigthforward process, since I experienced some weird errors such as: ORA-28003: password verification for the specified password failed, ORA-20001: Password length less than 8, and ORA-01917: user or role ‘LBACSYS’ does not exist. After having a look at several log files, I found the root causes of this error. Below, you…

Three basic points on SQL Server Best Practice

By | Technology Survey | No Comments

A few weeks ago, I went to the Swiss Database Days 2013 and followed the “Practical SQL Server Performance Troubleshooting” workshop. During this workshop, I have seen a different way of troubleshooting, but I was surprised to see that some participants were not aware that some basic SQL Server Best Practice do not depend on the instance settings. This blog posting is a reminder of some of these points. Swiss Database Days 2013: SQL Server…
