Playing with puppet vol VII - Oracle module

I've found a puppet module used for installation of Oracle database. It can install database software (Single DB, RAC, Grid, ASM), apply patches and create/start DB instances (see link above for complete list of features). I'll use it to install 11.2.0.3 oracle home, upgrade opatch to 11.2.0.3.6 and to apply PSU11 and timezone patch.

Udev as alternative for ASMlib in virtual Centos 6

I was trying to setup RAC in virtual environment. My virtual machines are Centos 6.5. Unfortunatelly there is no kmod-oracleasm for default kernel 2.6.32-431. To be completelly true, there is required kernel module, but it is only available for redhat subscribers. There I will describe how to use udev instead of asmlib.

Simulating long distance network in Data Guard environment

I was curious about Oracle Data Guard over long distance with synchronous redo transfer. In this mode session waits on commit until redo is written on standby site. When standby is far far away, most time is spent on waiting for redo write acknowledgement. I will show it in today's post.

Add Oracle database related services to firewalld

I was setting up data guard environment on Centos 7 machine for testing purposes. Usually I disable iptables firewall at first, but this time firewall stays on and I'll make all necessary holes into it.
