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

I have got a input string like "[key1:value1,key2:value2]", how to get the value by key?

1) Which log file is used to view users' activity like password Chage, user type change, reactivate/deactive, username change? 2) Which log file to view the process failure in detail? 3) Log file to view the user login audit? 4) Log file to give details about slow queries?

It doesn't appear the option from the menu

We are running a HA env with 3 app servers behind the Apache. We are using mod_jk and JKWorkerProperty to set up the load balancing in httpd.conf as provided in the Appian documentation. Issue is, we notice that whenever one of the tomcat servers are down, requests are still routed to the instance. This doesn't happen when entire instance is down.  I assume Apache is doing a basic TCP to determine the health of the backend server. I want to know if I can configure a tomcat health check GET url in my Apache config to determine the health of the instance from apache?

How to get the memory occupied by the knowledge center documents in Appian server? Tried with Admin console -> Monitoring, and it is providing size for the list of documents uploaded/downloaded? My requirements is get the actual space occupied by the knowledge center documents in Appian cloud environment.

Dear Team, I am new comer to Appian have background of IBM BPM, Can you please guide where to find  inner exception details (log for this error) of a smart service ( Move to Collab). It is giving error  com.appiancorp.suiteapi.process.exceptions.SmartServiceException: java.lang.Exception: Invalid File Path: /webattachments/path/foldername//info@alwaha-qatar.com/qid20220327080031286QID_&_PP.pdf we are using to move files from file server to appian mount path but it is completed sometimes & gives above error some times.

Are there any official, generic guide lines when it comes to retention of information stored in the database and the documentation stored in knowledge centers (when to archive, eliminate, how to handle such situation)? It's obvious we'd have to tailor it to our specific application but I wanted to start by observing any suggestions given by Appian.  Best Regards.

I am getting some entries in Health Check report for USRX-0041: "# of slow process tasks". There is no information link about this specific issue to https://docs.appian.com/suite/help/24.4/understanding-the-health-check-report.html I could see that  all our HIGH risk entries are process tasks with interfaces. Does anyone know how to properly solve slow process tasks? It's related to the average time spent loading/rendering the interfaces? I can see that some of those interfaces are not present on the "# of slow interfaces" item.

Hi All, I am having a specific situation where I need your feedback and suggestions. There is a Record A pointing to Table A and Record A is having relationship with Record B (Table B). For some reasons I have created Record B1 pointing to same Table B and added the relationship in Record A. What could be the issue / performance issue with this type of relationship? Note: This is only one relationship I have explained in above example,  in actual we have more then 10 such relationships.

Is there any way to update process Calendar using process Model without giving the administration access to user by using interface.

Hello, In Admin Console, we have configured "Idle Session Timeout" as 20 minutes . The users authenticate using SAML via SSO login. However, we observed that the session is not timed out in 20 mins always. If we open multiple tabs, certain tabs are timed out whereas few are still logged in after 20 mins. Is there any reason or configuration change which needs to be done? Thanks in advance..

Hello, I have a use case where i have to provide all record Id's and record name in Picker Field. Users can select from it. I have been fetching only id and name column from DB table .

Hi, We have configured SAML login in our environment but we are having trouble mapping the email attribute. Our client has two types of SAML users: internal who have their email defined in the email claim. external who do not have any value defined in the email claim, is empty when accessing Appian, and have their email in the name claim. We are trying to find a way to make this mapping dynamic so it can work for both type of users with the same Idp. We need a way to validate if the email claim is empty and map the name claim instead, is this possible? We haven't found any way to do this but we wanted to ask in case anyone knows or has any ideas that we can try. Thanks in advance

Hi, We are configuring SAML login in our client cloud environment and we have seen in the documentation that Appian allows encryption for the SAML assertion "Appian supports signed, encrypted SAML assertions up to the AES-256 standard" but the information in the documentation is very limited.The question we have is if we configure encryption with AES-256 in the IDP (Azure AD), how is the decryption key stored in Appian? Do we have to provide the key to Appian to store it internally or register it in the credential store? Thanks in advance

Hi, we have configured SAML login in our environment and we need to store the SAML Bearer assertion in order to get new tokens for the users while the assertion is valid. The issue we are facing is that users can have more than one session active in Appian at the same time, and for each session we need to store the assertion related to the session UUID so we can differentiate them. I am able to retrieve the user active sessions using the plug-in User Session Checker or the login-audit log to store the session UUID with the assertion, but I need a way to get the specific user session at the moment (current session) so I can filter my query with this value and get the correct assertion.  I tried looking for any function or plug-in that will allow this but found none, so if anyone knows a way it could be accomplish will be really helpful. Thanks in advance
