NGINX Secured Distribution Path with GoldenGate REST API
In a previous blog, I presented how to set up a distribution path between two GoldenGate deployments both secured with NGINX. The method I used there was purely through the Web UI. But GoldenGate also exposes a full REST API, and everything you can do in the UI can be done through the API as well, which is useful for automation, scripting, or when the UI is not reachable.
This blog covers the exact same setup, using the REST API instead. I will show two ways of doing it :
- Using
oggrestapi.py, the GoldenGate REST client I released in another blog. - Using the
requestslibrary to call the REST API directly.
The prerequisites are the same as in the previous blog :
- Two GoldenGate Microservices deployments,
ogg_test_01(source) onoggvm1andogg_test_02(target) onoggvm2. I will use the latest 26ai version. - Both OGG setups secured with NGINX acting as a reverse proxy, so everything goes through port
443. - A running extract on the source, writing to a trail (
aain my case).
Just like in the Web UI, there are three steps to get a working distribution path :
- Create a path connection on the source, to authenticate against the target.
- Register the target’s CA certificate on the source Service Manager.
- Create and start the distribution path.
A quick note on URLs before we start. Behind an NGINX reverse proxy, each service has its own path prefix :
- Administration Service :
/services/<deployment>/adminsrvr/v2/... - Distribution Service :
/services/<deployment>/distsrvr/v2/... - Service Manager :
/services/ServiceManager/v2/...
The oggrestapi.py client builds these for you as soon as you pass reverse_proxy=True and the deployment name, so let’s connect once and reuse the client. If you don’t provide the password argument, you will be prompted for it.
from oggrestapi import OGGRestAPI
ogg_source = OGGRestAPI(
url="https://oggvm1",
username="ogg",
deployment="ogg_test_01",
reverse_proxy=True,
)
Create the path connection
As explained in Creating Path Connections with GoldenGate REST API, a path connection is simply an alias in the Network domain. It stores the credentials of a user that exists on the target deployment, and its alias is only known on the source side.
With the client, just call the create_alias method :
ogg_source.create_alias(
alias="ogg_target",
domain="Network",
data={
"userid": "ogg_user_on_target",
"password": "***",
},
)
As mentioned in the introduction, here is the same call with requests, calling the Administration Service of oggvm1 through NGINX :
import requests
auth = ("ogg", "ogg_password")
response = requests.post(
"https://oggvm1/services/ogg_test_01/adminsrvr/v2/credentials/Network/ogg_target",
auth=auth,
json={
"userid": "ogg_user_on_target",
"password": "***",
},
)
After refreshing the source Web UI, the new path connection is visible under the Path Connections tab :
But of course, you can also view the new path connection by calling the REST API:
# Since path connections are aliases of the Network domain, we use the get_alias method to retrieve them
>>> ogg_source.get_alias('Network', 'ogg_target')
{'$schema': 'ogg:credentials', 'userid': 'ogg_user_on_target', 'type': 'PASSWORD'}
Register the target’s CA certificate
Because the deployments are secured with NGINX, the source has to trust the certificate authority that signed the target’s certificate. This is done on the source Service Manager, by registering the target’s root CA certificate.
With the client, use create_deployment_certificate against the source deployment. The certificate type to use is truststore, and the certificate content goes under trustpointBundle.trustpointPem:
target_ca = open("rootCA_ogg_test_02.pem").read()
ogg_source.create_deployment_certificate(
deployment="ogg_test_01",
type="truststore",
certificate="rootCA_ogg_test_02",
data={
"trustpointBundle": {
"trustpointPem": target_ca,
}
},
)
The same call with requests, this time on the Service Manager prefix :
target_ca = open("rootCA_ogg_test_02.pem").read()
response = requests.post(
"https://oggvm1/services/ServiceManager/v2/deployments/ogg_test_01/certificates/truststore/rootCA_ogg_test_02",
auth=auth,
json={
"trustpointBundle": {
"trustpointPem": target_ca,
}
},
)
Registering under the specific deployment (ogg_test_01) is the equivalent of the Local option in the Web UI. To get the Shared behavior instead, register the same certificate under the ServiceManager deployment name, so it becomes available to every deployment on that node.
If the certificate file contains a chain of certificates, you must register each certificate individually, since GoldenGate does not accept them in one go. I described that issue in detail in a blog about the OGG-30007 error.
We can now create the distribution path itself. It has a source endpoint (the local trail) and a target endpoint (the target’s Receiver Service, reached over wss through NGINX). Because the target is NGINX-secured, the target URI :
- uses the
wssprotocol on port443, - points at the Receiver Service path prefix,
recvsrvr, notdistsrvr(that prefix is only for the Distribution Service on the source side), - does not carry the path connection alias itself. The alias goes in a separate
authenticationMethodkey.
With the client :
ogg_source.create_distribution_path(
distpath="path12",
name="path12",
source={
"uri": "trail://localhost/services/v2/sources?trail=PDB1/aa",
},
target={
"uri": "wss://oggvm2/services/ogg_test_02/recvsrvr/v2/targets?trail=PDB1/bb",
"authenticationMethod": {
"domain": "Network",
"alias": "ogg_target",
},
},
begin="now",
status="running",
)
And the equivalent requests call, on the Distribution Service prefix (/services/ogg_test_01/distsrvr/):
response = requests.post(
"https://oggvm1/services/ogg_test_01/distsrvr/v2/sources/path12",
auth=auth,
json={
"name": "path12",
"source": {
"uri": "trail://localhost/services/v2/sources?trail=PDB1/aa",
},
"target": {
"uri": "wss://oggvm2/services/ogg_test_02/recvsrvr/v2/targets?trail=PDB1/bb",
"authenticationMethod": {
"domain": "Network",
"alias": "ogg_target",
},
},
"begin": "now",
"status": "running",
},
)
The trail value in both URIs also has to match the path the extract actually registers, EXTTRAIL PDB1/aa on the source becomes trail=PDB1/aa in the source URI, and the same logic applies to the target’s bb trail. A bare trail=aa without the PDB path segment matches neither what the extract writes nor what the target’s own directory layout expects.
Once the path is created with status: "running", the trail files start flowing. You can confirm it on the target :
oracle@oggvm2:~/ ll $OGG_DEPLOYMENT_HOME/var/lib/data/PDB1
total 0
-rw-r-----. 1 oracle oinstall 0 Mar 22 07:34 bb000000000
The remote peer submitted a certificate that failed validation
If your distribution path doesn’t start and generates a “certificate that failed validation” error, it means that you incorrectly registered your certificates. Make sure that the target deployment’s CA certificate is registered on the source Service Manager, and not the other way around.
And that’s it. With three REST calls, through oggrestapi.py or using the requests module, you get the exact same NGINX-secured distribution path as the Web UI method, but in a form you can script and repeat.

Oracle AI Database 26ai (23.26.2) Supported on Oracle Linux 10 (OL10)
A few weeks ago Laurent Schneider messaged me to say Oracle Database 26ai (23.26.2) was supported on Oracle Linux 10 (OL10). That started the usual series of test builds. Basic Installations I already had an installation article for 26ai on OL10, but I updated it, including using the new preinstall package which is now in … Continue reading "Oracle AI Database 26ai (23.26.2) Supported on Oracle Linux 10 (OL10)"

GoldenGate 26ai out-of-place patching with Python
I already covered out-of-place patching from the web UI, but patching tasks should be automated, and clicking through the same screens for every deployment can get repetitive. Let’s do the exact same out-of-place patch of a GoldenGate Microservices Architecture deployment, this time entirely with the REST API.
Every step below shows two ways to make the same call:
- A standard
requestscall, the default Python module to handle REST APIs. - The equivalent call using
oggrestapi.py, theOGGRestAPIPython client I presented in another blog, which handles everything for you.
This part does not change: the REST API cannot install software on the server, so you still need to unzip the patched installation to a new OGG_HOME and run runInstaller in silent mode, as described in the web UI blog.
As with the web UI, the Service Manager has to be patched first. Assume the following setup:
sm_url:https://vmogg:7809new_ogg_home:/u01/app/ogg/product/23.26.2.0.1username/password: an administrator on the Service Manager
Updating OGG_HOME is a PATCH call on the ServiceManager deployment:
import requests
sm_url = "https://vmogg:7809"
auth = ("oggadmin", "password")
requests.patch(
f"{sm_url}/services/v2/deployments/ServiceManager",
json={"oggHome": "/u01/app/ogg/product/23.26.2.0.1"},
auth=auth,
)
With oggrestapi.py:
from oggrestapi import OGGRestAPI
client = OGGRestAPI(url="https://vmogg:7809", username="oggadmin", password="password")
client.update_deployment(deployment="ServiceManager", ogg_home="/u01/app/ogg/product/23.26.2.0.1")
Already, you can see that the REST API client simplifies the patching a lot.
Restarting the Service Manager is the same endpoint, this time setting status:
requests.patch(
f"{sm_url}/services/v2/deployments/ServiceManager",
json={"status": "restart"},
auth=auth,
)
client.restart_deployment(deployment="ServiceManager")
restart_deployment is a dedicated method in oggrestapi.py, following the same pattern already used for restart_service, restart_extract and restart_replicat. It makes it easier to use the API, instead of building the {"status": "restart"} payload yourself. It also takes an optional only_if_running argument, so a deployment that was already stopped before the patch is left alone rather than being started by the restart call.
As with the web UI, all your deployment processes are still running on the old OGG_HOME at this point. The AIService, introduced in 26ai, does not pick up the new home automatically either. You should then list the services attached to the Service Manager and restart the ones that are not ServiceManager itself:
services = requests.get(
f"{sm_url}/services/v2/deployments/ServiceManager/services",
auth=auth,
).json()["response"]["items"]
for service in services:
if service["name"] != "ServiceManager":
requests.patch(
f"{sm_url}/services/v2/deployments/ServiceManager/services/{service['name']}",
json={"status": "restart"},
auth=auth,
)
for service in client.list_services("ServiceManager"):
if service.get("name") != "ServiceManager":
client.restart_service(deployment="ServiceManager", service=service.get("name"))
Patching each deployment with the REST API
Once the Service Manager runs on the new home, repeat the same update, then restart sequence for each deployment (oggHome, then status: restart):
deployment = "ogg_test_01"
requests.patch(
f"{sm_url}/services/v2/deployments/{deployment}",
json={"oggHome": "/u01/app/ogg/product/23.26.2.0.1"},
auth=auth,
)
requests.patch(
f"{sm_url}/services/v2/deployments/{deployment}",
json={"status": "restart"},
auth=auth,
)
client.update_deployment(deployment="ogg_test_01", ogg_home="/u01/app/ogg/product/23.26.2.0.1")
client.restart_deployment(deployment="ogg_test_01")
Once the deployment is back up, restart its extracts and replicats. Since these processes are not accessible through the Service Manager port, you need to change the URL. If you use a reverse proxy setup, or auto_discovery=True (see below), this is also easier with the Python client.
admin_url = "https://vmogg:7810"
extracts = requests.get(f"{admin_url}/services/v2/extracts", auth=auth).json()["response"]["items"]
for extract in extracts:
requests.patch(f"{admin_url}/services/v2/extracts/{extract['name']}", json={"status": "stopped"}, auth=auth)
requests.patch(f"{admin_url}/services/v2/extracts/{extract['name']}", json={"status": "running"}, auth=auth)
replicats = requests.get(f"{admin_url}/services/v2/replicats", auth=auth).json()["response"]["items"]
for replicat in replicats:
requests.patch(f"{admin_url}/services/v2/replicats/{replicat['name']}", json={"status": "stopped"}, auth=auth)
requests.patch(f"{admin_url}/services/v2/replicats/{replicat['name']}", json={"status": "running"}, auth=auth)
With oggrestapi.py, restart_all_extracts and restart_all_replicats do the same thing on an OGGRestAPI client already pointed at the deployment (either connected directly to its Administration Service, or through an NGINX reverse proxy with deployment= set):
admin_client = OGGRestAPI(url="https://vmogg:7810", username="oggadmin", password="password")
admin_client.restart_all_extracts(only_if_running=True)
admin_client.restart_all_replicats(only_if_running=True)
Automating the whole patching in one call
The steps listed above (update home, restart deployment, restart processes for every deployment) is exactly what patch_deployment (a single deployment) and patch_deployments (all of them) already do in oggrestapi.py, internally calling restart_deployment for the restart step. They also handle the ServiceManager special case (patch and restart the deployment and its services, but never restart extracts and replicats on it) and the wait_until_deployment_status polling in between:
client = OGGRestAPI(url="https://vmogg:7809", username="oggadmin", password="password", reverse_proxy=True)
client.patch_deployments(new_home="/u01/app/ogg/product/23.26.2.0.1", ask_credentials=False)
Both methods take restart_after_patch and restart_processes_after_patch (both default to True) if you need to skip either step, for example to patch every home first and restart everything in a separate maintenance window:
client.patch_deployments(
new_home="/u01/app/ogg/product/23.26.2.0.1",
restart_after_patch=False,
restart_processes_after_patch=False,
ask_credentials=False,
)
restart_processes_after_patch=True needs per-deployment routing: restarting extracts and replicats on ogg_test_01 is a different call than on ogg_test_02, and a plain connection to the Service Manager’s own port has no way to reach either one. oggrestapi.py gives you two ways to get that routing from a single client:
reverse_proxy=True, shown above, if you already run NGINX in front of your deployments.auto_discovery=True, with no reverse proxy at all. The client looks up each deployment’s real Administration/Distribution/Performance Metrics Service port through the Service Manager itself (the sameGET .../deployments/{deployment}/services/{service}call), the first time each one is actually needed, and reuses that lookup for the rest of the run:
client = OGGRestAPI(url="https://vmogg:7809", username="oggadmin", password="password", auto_discovery=True)
client.patch_deployments(new_home="/u01/app/ogg/product/23.26.2.0.1", ask_credentials=False)
Without either flag, patch with restart_processes_after_patch=False and restart each deployment’s processes yourself through a separate client pointed at that deployment’s own admin URL.
OGG_HOME
Same as with the web UI: a restart call on a deployment returns as soon as the Administration Service (adminsrvr) is back up. The Receiver Service (recvsrvr) or the Distribution Service (distsrvr) can take a bit longer to restart. If, after polling for a few minutes, a service is still reporting the old home, restart it individually with the same PATCH .../services/{service} call shown above for the AIService, or with the restart_service method.
If you change the name of your home at every release, remember to update OGG_HOME in every script and environment that references it, for example:
- DMK environment files.
systemdservice files, which might hardcode theOGG_HOMEvariable.

M-Files Compliance Kit 2026 is available
Recently, I decided to conduct an initial test involving a review in one of our test environments. The aim was twofold: to explore the new features and to verify the update process. You can read about my experience and the outcome in this blog post.
In week 29 of 2026, M-Files released a new version of its widely known and used M-Files Compliance Kit. This is especially useful if you are looking for advanced workflow capabilities or working in a regulated environment. The Compliance Kit is an essential tool.
This first version of the 2026 edition was followed by several smaller updates and fixes, culminating in version 2026 (26.9.16376.0).In this blog, I will highlight some of the improvements that I consider significant. The full release notes can be found on the M-Files official website.
This does not reflect the complete list, but it does include some of the most important parts.
Features- Object Creator commands and groups can use custom icons (including your own SVG or image-based icons).
- You can create and arrange custom task bar groups, control their placement and priority, and merge them with built-in groups.
- Commands can be shown outside their group in the context menu to match the classic client’s layout.
- Existing configurations continue to work with no changes required — classic client behavior is preserved, and legacy icons are reused automatically in newer clients where appropriate.
- CAD File Preview Support
CAD files with extensions .dwg, .dxf, .dwt, and .dgn can be previewed within the new Clients Preview tab, utilizing the active layout. The maximum supported file size is 50 MB. Previews are generated using a converted PDF format. Administrators have the capability to enable this conversion process for workflow state transitions or on-demand PDF conversion through the “Configuration>PDF Conversion (Indexing, File Preview, Workflows)>CAD Files>Enable On-Demand Conversion” setting, which is disabled by default.
- Activity feed now identifies AI-driven changes
When an object’s metadata is edited automatically based on an AI response, the activity feed now shows “M-Files AI” as the editor instead of a generic “M-Files” entry, making it clearer when a change was made by AI rather than a person. - Icons in view listing columns
The new M-Files client now shows a small icon next to value-list values in view listing columns — Workflow, Workflow state, Class, Object Type, and any custom value list item — so users can recognise the state, class, and type of each object at a glance without opening it. - Improved metadata card appearance
The metadata card now correctly displays custom colors for property group headers and descriptions. This ensures a more consistent and visually clear experience when viewing object details. - Drag-and-drop support for relationships and document collection management
Users can now drag and drop one or multiple objects onto another object in the listing to add documents to a document collection, establish relationships, append files to a multi-file document, or replace a file’s content. - Edit documents stored in M365 Storage using Web Co-Authoring
You can now open and co-author documents directly in the Office Web version using the new ‘Edit in Web’ option in the context menu. This makes it easier to collaborate online without needing the Office Desktop application. - UIXv2: show multiple dashboards in a popup window
You can now display up to three dashboards side by side in a pop-up window using the UI extensibility framework (UIXv2). This helps you compare information and work more efficiently without switching views.
As previously mentioned, a large number of improvements have been made and many defects have been fixed. Please refer to the official M-Files documentation for further details.
Installation and Update processI can confirm that the installation and update process was very straightforward and worked without any issues. As always, you can simply install the new Vault Framework application in the Vault. There is no need to uninstall the previous version.
After installation, navigate to the Compliance Kit configuration in the Vault. As in previous versions, an update button will be displayed. Pressing this button starts the update process, which went very well in my test. Afterwards, the Compliance Kit worked as expected, with all configurations and settings remaining intact.
After restarting and refreshing the vault, the upgrade application is shown under configuration. Next, we can start the final update process by pressing the button, as shown in the screenshot.
Once again, the M-Files Admin Tool is refreshed and the result of the update confirms that the new version of the Compliance Kit is 2026.
Example of new features
The examples below demonstrates the new features of the M-Files Compliance Kit 2026, as implemented in a Quality Management System (QMS) demo vault.
The picture below shows the new features based on an approved change request. Refer to the cycle in the picture to see the commands available for an approved change request. This makes it very easy to create a new document based on the approved change request.
This function was already available in the classic client but was sorely missed by almost every user in the new client.
Web Client
Conclusion
With all the improvements and fixes, particularly the new client’s command retrieval function. This is a step in the right direction. If you’re wondering how it works in the web client.Tthe answer is that anything that works in the new client also works in the web client.
If you have any questions or would like a demonstration, please get in touch with us. We can also assist with installation, updates and configuration.
