Thank you for your replying ,
this my docker compose that i have already did ,but still in orthanc storage folder

DOCKER-COMPOSE.YML
pacs:
image: pacs_second
ports: [ “8042:8042”, “4242:4242” ]
volumes:
- pacs-storage:/var/lib/orthanc/db
- ./demo-setup/config.json:/etc/orthanc/orthanc.json
- ./demo-setup/config.json:/root/orthanc.json
depends_on: [ pacs-db ]
env_file:
- ./demo-setup/common.env
environment:
VERBOSE_ENABLED: “true”

pacs-db:
image: postgres:14
volumes: [ “pacs-db:/var/lib/postgresql/data” ]
environment:
POSTGRES_HOST_AUTH_METHOD: “trust”
POSTGRES_PASSWORD: “pacs”
POSTGRES_USER: “pacs”
POSTGRES_DB: “pacsdb”

Orthanc config , postgres plugin config:
“PostgreSQL”: {
“EnableIndex”: true,
“EnableStorage”: true,
“ConnectionUri”: “postgresql://pacs:pacs@pacs-db:5432/pacsdb”,
// “Database”:“pacs-db”,
“Lock” : false,
// //view .yml file
// “Username”: “pacs”,
// “Password”: “pacs”,
“EnableSsl”: false, // New in release 3.0
“MaximumConnectionRetries”: 10, // New in release 3.0
“ConnectionRetryInterval”: 5, // New in release 3.0
“IndexConnectionsCount”: 1, // New in release 4.0
“TransactionMode”: “ReadCommitted”, // New in release 6.0 ||Serializable
“EnableVerboseLogs”: true // New in release 6.0
}

Question :
Will the data be completely saved in the postgres database after replication, instead of being stored in OrthancStorage, or only the metadata part?

Hello,

The configuration that you have posted contains both “EnableIndex”: true and “EnableStorage”: true. Therefore, postgres will be used both for the DB/metadata and for DICOM storage.

Please note that changing your configuration will not remove or migrate the existing files.

If the newly stored files are still saved to the local storage, you might want to post detailed log files

(Why do you map the same file at two locations with - ./demo-setup/config.json:/etc/orthanc/orthanc.json and - ./demo-setup/config.json:/root/orthanc.json ? )

I appreciate your help !

Q : (Why do you map the same file at two locations with - ./demo-setup/config.json:/etc/orthanc/orthanc.json and - ./demo-setup/config.json:/root/orthanc.json ? )
Response Q : its just to make sure that my config will be used , in both case , if orthanc reads the config from /etc/orthanc or in /root

Hi @brokendev (I feel a little bad using your handle to address you :rofl:)

Being given my input above, and your logs that seem to indicate that Postgres is indeed running fine, what is the situation?

As a recap, you should not see any new Dicom resource that you would import into Orthanc being saved to the filesystem storage (...Using a custom storage area from plugins...). Is that so?

Just let us know in case of any pending issue.

There’s no problem, it’s my last file log and I thought it was good, I’d just like to have your opinion,
Thank you for your attention. :sweat_smile:
