The releases directory contains a copy of each
installed release. As new versions are installed and updated (through
tpm update), a new directory is created with the
corresponding version of the software.
For example, a number of releases are listed below:
shell> ll /opt/continuent/releases/
total 20
drwxr-xr-x 5 tungsten mysql 4096 May 23 16:19 ./
drwxr-xr-x 9 tungsten mysql 4096 May 23 16:19 ../
drwxr-xr-x 10 tungsten mysql 4096 May 23 16:19 tungsten-clustering-6.1.25-6_pid16184/
drwxr-xr-x 10 tungsten mysql 4096 May 23 16:19 tungsten-clustering-6.1.25-6_pid14577/
drwxr-xr-x 10 tungsten mysql 4096 May 23 16:19 tungsten-clustering-6.1.25-6_pid23747/
drwxr-xr-x 10 tungsten mysql 4096 May 23 16:19 tungsten-clustering-6.1.25-6_pid24978/
The latest release currently in use can be determined by checking the
symbolic link, tungsten within the installation
directory. For example:
shell> ll /opt/continuent
total 40
drwxr-xr-x 9 tungsten mysql 4096 May 23 16:19 ./
drwxr-xr-x 3 root root 4096 Apr 29 16:09 ../
drwxr-xr-x 2 tungsten mysql 4096 May 30 13:27 backups/
drwxr-xr-x 2 tungsten mysql 4096 May 23 16:19 conf/
drwxr-xr-x 3 tungsten mysql 4096 May 10 19:09 relay/
drwxr-xr-x 5 tungsten mysql 4096 May 23 16:19 releases/
drwxr-xr-x 2 tungsten mysql 4096 May 10 19:09 service_logs/
drwxr-xr-x 2 tungsten mysql 4096 May 23 16:18 share/
drwxr-xr-x 3 tungsten mysql 4096 May 10 19:09 thl/
lrwxrwxrwx 1 tungsten mysql 63 May 23 16:19 tungsten -> /opt/continuent/releases/tungsten-clustering-6.1.25-6_pid24978/
If multiple services are running on the host, search for
.pid files within the
installation directory to determine which release directories are
currently in use by an active service:
shell> find /opt/continuent -name "*.pid"
/opt/continuent/releases/tungsten-clustering-6.1.25-6_pid24978/tungsten-replicator/var/treplicator.pid
/opt/continuent/releases/tungsten-clustering-6.1.25-6_pid24978/tungsten-connector/var/tconnector.pid
/opt/continuent/releases/tungsten-clustering-6.1.25-6_pid24978/tungsten-manager/var/tmanager.pid
Directories within the releases directory that are
no longer being used can be safely removed.
