Running an Oracle Database (DB) Container on your laptop, regardless of your device, is a common practice for professionals in lab and engineering environments. These containers offer a convenient solution for setting up and managing Oracle databases for various purposes. However, there are scenarios where you need to interact with the Oracle DB Container using […]
Today’s #JoelKallmanDay, my topic is about simplifying the configuration of Kerberos authentication of Oracle databases using Linux tools. I have already written a few things about Kerberos in the past. The blog posts on this topic are usually tagged with Kerberos. Today I want to show you an alternative method how to create the keytab […]
I have several Oracle Cloud Infrastructure (OCI) based Lab environments, which I build with Terraform and corresponding shell scripts. Unfortunately the labs are not one size fits all. Depending on what I’m testing, I have different requirements for the available filesystems. So every now and then I face the problem that I have to increase […]
Another food blog post? No, of course not. Guacamole in this case does not refer to the avocado-based dip, but to the Apache client less remote desktop gateway. We use this as an alternative access to the OCI based Trivadis LAB environment. We use an automatically configured Guacamole environment with Nginx reverse proxy and Let’s […]
About a year ago I explained in the blog post Start OUD Servers on Boot using systemd how to start Oracle Unified Directory automatically on system startup. In the meantime a lot has changed, so has my unit file. The simple unit file actually worked quite well. Until the time came when I installed an […]
Recently I ran out of movies on one of my longer train rides. Coincidentally, I had my Raspberry Pi Zero with me and thought, “There’s Java running on it, right?”. Doesn’t Oracle Unified Directory also require a JVM? OK, I guess Raspberry Pi or ARM wasn’t in focus when Oracle defined the certified platforms of […]
Starting Oracle Unified Directory on system boot is essential for production environment. Unfortunately OUD just provides a script to create the init.d script. But newer system in general use systemd initialise and startup. Nevertheless, creating a custom unit file for OUD is simple and straightforward. First, let’s create a regular init.d script with the create-rc-script […]
A couple of days ago I’ve wrote about some problems when installing Oracle Audit Vault and Database Firewall 12.1.2 on HP server with Smart Array Disk Controller. The problem is still not resolved, but in the meantime Oracle has open a Bug and added some Metalink Notes related to this issue. AVDF 12.1.1 Installation Fails […]
I’ve successfully set up a couple of AVDF installation on different VM Server as well on HP Blade or Rack servers. On the VM server I never had any problems. For the installation of AVDF 12.1.1.x on HP servers BL465c Gen8 or DL380p Gen8, there were always warnings during partitioning of the disks. So far […]
While working on the problem with missing RAM on the AVDF test system (see ) I realized, that the linux boot partition is not available by default. [root@melete2 log]# ls -al /boot total 16 drwxr-xr-x 2 root root 4096 Jan 11 2013 . drwxr-xr-x 24 root root 4096 Jul 11 20:19 .. [root@melete2 log]# df […]
After initial setup of an Audit Vault and Database Firewall engineering system, I’ve started to add several audit vault agents and secure targets. In the beginning it went quite smoothly. But after a certain number of secured targets, there were continuously ORA-04031 errors. Most of the errors were related to large pool and PX Msg […]
