|Important information for upgrading to BASE 3.19|
This section list some important information that may or may not apply when upgrading from the previous BASE release to the current release (eg. 3.18 to 3.19). If you are upgrading from a BASE installation that is older (3.0-3.17) you should also read Appendix J, Things to consider when updating an existing BASE installation.
BASE 3.18 was the last release that supported MySQL. Since BASE 3.19 we are only testing and supporting PostgreSQL. BASE may still work with MySQL after that, but we recommend that existing installations are migrated to PostgreSQL as soon as possible.
As always, backup your database before attempting an upgrade. The BASE team performs extensive testing before releasing a new version of BASE but there are always a possibility for unexpected events during upgrades. In upgrades requiring a change in the underlying database there is no (supported) way to revert to a previous version of BASE using BASE tools, you need to use your backup for this use case.
The strategy here is to install the new BASE release to another directory than the one in use. This requires transfer of configuration settings to the new install but more on that below.
If the BASE application is not shut down already, it is
time to do it now. Do something like
|Notify logged in users!|
If there are users logged in to your BASE server, it may be nice of you to notify them a few minutes prior to shutting down the BASE server. See Section 21.4.1, “Sending a broadcast message to logged in users”.
Rename your current BASE installation
There are several ways to download BASE. Please refer to section Section 3.1.1, “Download” for information on downloading BASE, and select the item matching your download option:
If you selected to download a pre-compiled package,
unpack the downloaded file with
If you selected to download a source package, unpack
the downloaded file with
base-...src.tar.gz. Change to the new
directory, and issue
package.bin. This will create a binary
package in the current directory. Unpack this new
package (outside of the source file hierarchy).
This option is for advanced users only and is not
covered here. Please refer to
Settings from the previous installation must be transferred to the new installation. This is most easily done by comparing the configuration files from the previous install with the new files. Do not just copy the old files to the new install since new options may have appeared.
In the main BASE configuration file,
fields that needs to be transferred are usually
Local settings in the raw data

It is recommended that you also perform an update of your
database schema. Running the update scripts are not
always necessary when upgrading BASE, but the running the
update scripts are safe even in cases when there is no
need to run them. Change directory
<base-dir>/bin/ and issue
sh ./updatedb.sh [base_root_login] base_root_password
where base_root_login is the login
for the root user and base_root_password is the
password. The login is optional. If not specified,
root is used as the login.
Start the Tomcat server:
Done! Upgrade of BASE is finished.
