I'm creating a new interface object to display several pie charts. The data for the charts is stored in a local variables in the parent interface object which references my children interfaces. In terms of performance, what is the most efficient method to access the data required for the pie charts? Create a rule input on the children interfaces and pass the local variables data from the parent interface or query the data separately in the child interface to avoid passing it from the parent interface?

Hi All, Is there any way to automate Appian Application (App Server, search Server, data Server and Engines) shutdown and start for Appian on premise? Thanks

Hi All, Appian used to have the capability of exporting the report in single click on legacy portal. But now that default download capability is available in Record only but not on reports. Do we have any way to implement it as Appian OOB capabilities?

We have annual security audits in our company. This year Appian entered in this process and the auditor is consulting us about backups. We have contracted the Essential cloud service. We understand that Appian has some sort of solution (cluster) on top of cloud environments. Where can I find this documentation? Is there a recommended procedure by Appian to backup our information? How can I ensure that in the event of an event I can recover our productive environment?

Hello,  I am having trouble with the following use case : we receive 3 large Excel files daily (~60 000 rows and 40 columns), that we need to read and write into Appian Cloud Database. So far, we've been doing that this way :  1. Use an ETL to read the file and batch the extracted JSON data 2. Send the data in batches to Appian with an API exposed by Appian 3. The API triggers a process that write the data to the table (Using the node Write to Data Store Entity) However, this approach is starting to cause some memory issues, as there is more than 150 processes trigerred daily, and each of these processes contains large process variables (even with batching, we still have 150 processes dealing with 500 rows each). I am wondering what would be the best way to deal with this issue according to best practices. I've thought about using a!writeToMultipleDataStoreEntities directly in our API instead of triggering a process, to avoid having too many process running, but

Hi, I am currently interested about best practices for process deployment, and I've read a thread (please see the link below) about a critical issue. I've read a reply explaining that "key-value pair mapping" is a best practice for connecting Interface/SAIL with process to avoid deployment issues. Could you explain me what this best practice is about please ? or just give me a litlle example ?

Hi there. If I select the “Generate groups and folders to protect and organize objects” option when creating a new Application, what groups are created by default? I think they were “Administrators” and “Users” but I saw in a forum that someone was talking about the “Designers” group being created as well. Is this true?

Hi Team, I have below text and I want to convert it into a Date and Time. Example: Text:  "01/07/2025 12:00:35 PM" Date and Time: 01/07/2025 12:00:35 PM or 01/07/2025 12:00:35 PM GMT+00:00

i just have a general question about this statement in the documentation, "By default Appian runs with 3 shards each of the execution and analytics engines. The maximum number of shards for each of these engines is 32. Because they store unique data, once you have added a new shard for execution and analytics, you cannot remove that shard from your configuration."  Does this mean one engine can have between 3 to 32 shards? 1 : 3 ... 1: 32. Thank you.

Hello All, Our new RHEL9 Acceptance environment is upgraded to version 24.3 but after upgrade we are unable to access the one app server directly (without load balancer). Previously we could access app server directly using URL "https://{HOSTNAME}/suite/?signin=native" But now I can login but it gives me CORS request rejected error message. Previously before upgrade I added {HOSTNAME} to embedded interface list in admin console and it was working. can you please help me in this how to bypass or update CORS valid list directly in database. Not sure but looks like it is wiped out after upgrade.  Here is error details : 2025-01-14 22:50:40,903 [ajp-nio-0.0.0.0-8009-exec-1] ERROR com.appiancorp.security.cors.CorsFilter - CORS request rejected; invalid request from XXX.XXX.XXX.25 to /auth jakarta.servlet.ServletException: CORS origin denied: {HOSTNAME} is not on the allowed list:[ Thanks, Bhushan

Hi,  We have a requirement that some communications between Appian and external systems have to be encrypted with mTLS. Does anyone know what is needed to generate a mTLS certificate and how to configure it in Appian? Thanks in advance

Hi all, I am writing with regards to an issue that we have found while upgrading from Appian 22.4 to Appian 24.3 in both the Dev and Test environments.We followed the procedure described in the documentation and found no issues during the upgrade process. However, when starting the Appian engines, we noticed the 3 analytics engines and the 3 execution engines were in CRASHLOOPBACKOFF state. The other engines were in RUNNING state as expected. We resolved the issue running the recovery script with these parameters: ./recovery.sh -p <password> -s <failing_engines> -ni  Then, the engines started correctly, and all the servers started up fine as well. However, the exiting process instances had disappeared from the Appian design view. Is there any way to refine the parameters used in the recovery script or another solution to recover the engines in CRASHLOOPBACKOFF state? As the same issue has happened in the Dev and Test environments we are concerned that it could happe
