MariaDB ColumnStore software upgrade 1.1.6 GA to 1.1.7 GA

MariaDB ColumnStore software upgrade 1.1.6 GA to 1.1.7 GA

Additional Dependency Packages exist for 1.1.7, so make sure you install those based on the "Preparing for ColumnStore Installation" Guide.

Note: Columnstore.xml modifications you manually made are not automatically carried forward on an upgrade. These modifications will need to be incorporated back into .XML once the upgrade has occurred.

The previous configuration file will be saved as /usr/local/mariadb/columnstore/etc/Columnstore.xml.rpmsave.

If you have specified a root database password (which is good practice), then you must configure a .my.cnf file with user credentials for the upgrade process to use. Create a .my.cnf file in the user home directory with 600 file permissions with the following content (updating PASSWORD as appropriate):

[mysqladmin] 
user = root
password = PASSWORD

Additional Library Install: Jemalloc

Note: This release introduces a dependency on the jemalloc os library to resolve some memory management issues that can lead to memory leaks. On each ColumnStore you must install jemalloc:

For CentOS:

yum install epel-release
yum install jemalloc

For Ubuntu and Debian:

apt-get install libjemalloc1

For SLES:

zypper addrepo https://download.opensuse.org/repositories/network:cluster/SLE_12_SP3/network:cluster.repo
zypper refresh
zypper install jemalloc

Choosing the type of upgrade

As noted on the Preparing guide, you can installing MariaDB ColumnStore with the use of soft-links. If you have the softlinks be setup at the Data Directory Levels, like mariadb/columnstore/data and mariadb/columnstore/dataX, then your upgrade will happen without any issues. In the case where you have a softlink at the top directory, like /usr/local/mariadb, you will need to upgrade using the binary package. If you updating using the rpm package and tool, this softlink will be deleted when you perform the upgrade process and the upgrade will fail.
