(more…)Setting up Oracle Database for development
To set up an Oracle Database for development I install the database in a docker container and then modify password policies in the default user profile as follows:
ALTER PROFILE DEFAULT LIMIT COMPOSITE_LIMIT UNLIMITED
PASSWORD_LIFE_TIME UNLIMITED
PASSWORD_REUSE_TIME UNLIMITED
PASSWORD_REUSE_MAX UNLIMITED
PASSWORD_VERIFY_FUNCTION NULL
PASSWORD_LOCK_TIME UNLIMITED
PASSWORD_GRACE_TIME UNLIMITED
FAILED_LOGIN_ATTEMPTS UNLIMITED;
this prevents passwords from expiring and users from being locked.
(more…)A simple C++ serialization framework
I implemented a simple C++ binary serialization framework that makes a structure or class serializable by adding a macro that usually takes one line of code as shown in the example below:
struct A
{
bool x;
int y;
AWL_SERIALIZABLE(x, y)
};
There is also a macro that makes a structure or a class equatable:
AWL_MEMBERWISE_EQUATABLE(A)
Oracle Database 19c auditing with Multitenant Architecture
First I installed Oracle 19c in Docker container , enabled unified auditing, and created multiple pluggable databases:
export ORACLE_SID=ORCLCDB
cd $ORACLE_HOME/bin
#connect to root container
./sqlplus / as sysdba
CREATE PLUGGABLE DATABASE testpdb1 ADMIN USER admin1 IDENTIFIED BY dbpasswd1
FILE_NAME_CONVERT=('/opt/oracle/oradata/ORCLCDB/pdbseed', '/opt/oracle/oradata/ORCLCDB/testpdb1');
Pluggable database created.
CREATE PLUGGABLE DATABASE testpdb2 ADMIN USER admin2 IDENTIFIED BY dbpasswd2
FILE_NAME_CONVERT=('/opt/oracle/oradata/ORCLCDB/pdbseed', '/opt/oracle/oradata/ORCLCDB/testpdb2');
Pluggable database created.
Installing Oracle Database 19.3 in a Docker container on Ubuntu Server 18.04
First I installed Ubuntu Server 18.04 as a Hyper-V machine on Windows 10.
While creating the virtual machine I selected Generation 1, because Generation 2 resulted in some strange effects.
Then I created a separate user with sudo permission:
sudo useradd -d /home/singh -m --shell "/bin/bash" singh
sudo passwd singh
sudo usermod -aG sudo singh

Inegrating Oracle Database 18 with MS Active Directory
