I’ve got an EdgeRouter LITE (ERL) which I used as my home router until a powercut fried it a while ago (looks like I’m not the only one to have this issue). The symptoms were it powering on but not giving any DHCP addresses, or after a factory reset responding on the default IP of 192.168.1.1. It was a real shame, because it had been a great bit of kit up until then.

(Previously, previously, previously) Since Proxmox 4 has a recent Linux kernel and mainline one at that, it means that Docker can be run on it. I’ve yet to really dig into Docker and work out when it makes sense in place of Linux Containers (LXC), so this is going to be a learning experience for me. To install Docker, add Backports repo to apt: root@proxmox01:~# cat /etc/apt/sources.list.d/backports.list deb http://ftp.debian.org/debian jessie-backports main And then install:

(Previously, previously) I’ve got a bunch of existing VirtualBox and VMWare VMs that I want to run on Proxmox. Eventually I’ll migrate them to containers, but for the time being run them as “fat” VMs using Proxmox’s KVM virtualisation. After copying the OVA files that I had to the server, I uncompressed them: root@proxmox01:/data04/vms/bdl44-biwa# cd ../bdl44 root@proxmox01:/data04/vms/bdl44# ll total 27249328 -rw------- 1 root root 27903306752 Jun 1 10:14 BigDataLite440.ova root@proxmox01:/data04/vms/bdl44# tar -xf BigDataLite440.

(Previously) With my server in place, I ran a memtest on it … which with 128G took a while ;) And then installed Proxmox 4, using a bootable USB that I’d created on my Mac from the ISO downloaded from Proxmox’s website. To create the bootable USB, create the img file: hdiutil convert -format UDRW -o target.img source.iso and then burn it to USB: sudo dd if=target.img of=/dev/rdiskN bs=1m Replace N with the correct device based on diskutil list output.

After a long and painful delivery, I’m delighted to announce the arrival of a new addition to my household … : This custom-build from Scan 3XS is sat in my study quietly humming away. I’m going to use it for hosting VMs for R&D on OBIEE, Big Data Lite, Elastic, InfluxDB, Kafka, etc. I’ll blog various installations that I’ve done on it as a reference for myself, and anyone else interested.

Oracle’s excellent Big Data Lite VM has been updated, to version 4.5. Download it here Changes: CDH 5.5 -> 5.7 Big Data Spatial and Graph 1.1 -> 1.2 Big Data Discovery 1.1 -> 1.2 Oracle Big Data Connectors 4.4 -> 4.5 Oracle NoSQL 3.5 -> 4.0 GoldenGate 12.2.0.1 -> 12.2.0.1.1

I’ve been spending some interesting hours digging into OBIEE 12c recently, with some interesting blog posts to show for it. Some of it is just curiosities discovered along the way, but the real meaty stuff is the in the RESTful APIs - lots of potential here for cool integrations I think… Lifting the Lid on OBIEE 12c Web Services - Part 1 Lifting the Lid on OBIEE 12c Web Services - Part 2 Extended Subject Areas (XSA) and the Data Set Service Changes in BI Server Cache Behaviour in OBIEE 12c : OBIS_REFRESH_CACHE Dynamic Naming of OBIEE 12c Service Instance Exports OBIEE 12c - “Add Data Source” in Answers (Photo credit: https://unsplash.

Presentation Services can provide some very detailed logs, useful for troubleshooting, performance tracing, and general poking around. See here for details. There’s no bi-init.sh in 12c, so need to set up the LD_LIBRARY_PATH ourselves: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/app/oracle/biee/bi/bifoundation/web/bin/:/app/oracle/biee/bi/lib/:/app/oracle/biee/lib/:/app/oracle/biee/bi/bifoundation/odbc/lib/ Run sawserver with flag to list all log sources /app/oracle/biee/bi/bifoundation/web/bin/sawserver -logsources > saw_logsources_12.2.1.txt Full list: https://gist.github.com/rmoff/e3be9009da6130839c71181cb58509a0

In OBIEE 12c data-model-cmd is a wrapper for some java code which ultimately calls an internal RESTful web service in OBIEE 12c, bi-lcm. We saw in the previous post how these internal web services can be opened up slightly, and we’re going to do the same again here. Which means, time for the same caveat: None of these Web Services are documented, and they should therefore be assumed to be completely unsupported by Oracle.

exportServiceInstance will export the RPD, Presentation Catalog, and Security model (application roles & policies etc – but not WLS LDAP) into a single .bar file, from which they can be imported to another environment, or restored to the same one at a later date (e.g. for backup/restore). To run exportServiceInstance you need to launch WLST first. The following demonstrates how to call it, and embeds the current timestamp & machine details in the backup (useful info, and also makes the backup name unique each time).
