To retrieve existing replication slots, execute: This can be done manually or by running hvrinit -d ( Drop Object option in GUI). For this reason, replication slots have to be removed when a channel is no longer needed. PostgreSQL will not remove transaction log files for which changes exist that have not been processed by a replication slot. This includes multiple HVR capture jobs and also coexistence with other replication products. This should allow multi capture in most situations. Hvr_ hub-name _ channel-name _ location-name

HVR uses the following naming convention for these replication slots: The names for these slots have to be unique for an entire PostgreSQL cluster. Replication SlotsĬapture/LogReadMethod = SQL uses PostgreSQL replication slots. In this method, HVR reads transaction log records using a special SQL function. This capture method supports capturing changes from regular PostgreSQL, Amazon RDS for PostgreSQL, and Aurora PostgreSQL. HVR captures changes using the SQL log read method ( Capture /LogReadMethod= SQL). $ /usr/hvr/hvr_home/lib/patchelf -set-rpath /usr/hvr/hvr_home/lib -force-rpath /usr/hvr/hvr_home/sbin/hvr_postgres To create a hvr_postgres executable, execute the following commands while logged in as the DBMS owner ( postgres): The operating system user as which HVR is running when connecting to PostgreSQL should have read permission to the files in this directory either directly, by running HVR as the DBMS owner ( postgres), or via a trusted executable $HVR_HOME/sbin/hvr_postgres. Parameter /Value should contain the directory path to the directory where the PostgreSQL transaction log files are archived (for example: /distr/postgres/935/archive). Parameter /Name should be set to HVR_LOG_RELEASE_DIR. HVR action Environment /Name /Value should be defined. The operating system user as which HVR is running when connecting to PostgreSQL should have read permission to the files in this directory either directly, by running HVR as the DBMS owner ( postgres) or via a trusted executable $HVR_HOME/sbin/hvr_postgres. Parameter /XLogDirectory should contain the directory path to the PostgreSQL transaction log file directory. HVR action Capture /XLogDirectory should be defined.This section lists and describes the connection details required for creating PostgreSQL/Aurora PostgreSQL location in HVR.Īlter system set archive_command = 'copy "%p" "c:\\Program Files\\PostgreSQL\\9.5\\data\\archive\\%f"' - server restart needed

For information about the client versions required for connecting to the PostgreSQL server, refer to the HVR release notes ( hvr.rel) available in hvr_home directory or the download page. libpq.so.5 and its dependencies) is installed on the machine from which HVR will connect to the PostgreSQL database. HVR requires that the PostgreSQL native LIBPQ (i.e.

Add this code to the ecs.This section describes the requirements, access privileges, and other features of HVR when using PostgreSQL/Aurora PostgreSQL for replication. Next, we need to provide an IAM policy to the prod_backend_task role and enable execute_command for the ECS service.

For macOS, you can use brew install session-manager-plugin. With Amazon ECS Exec, you can directly interact with containers without needing to first interact with the host container operating system, open inbound ports, or manage SSH keys.įirst, we need to install the Session Manager plugin. But how can we do it? Our infrastructure has no EC2 instances to connect via SSH and run this command. Now, we need to run migrations and create a superuser. This error means that the Django application successfully connected to PostgreSQL, but no migrations was run. You should get the relation "auth_user" does not exist error. Now, go to the admin URL on the load balancer hostname and try to log in with random credentials. Run terraform apply, stop current task via web console and wait for the new task to arise.
