Hi everyone, We recently encountered performance issues in our development environment and requested a restart. Before the full sequence could be executed, we have ran only: Code: appian_services_stop followed by starting it again without stopping the other components: appian_appserver_stop appian_searchserver_stopappian_services_stopappian_dataserver_stop We’d like to understand from the community: What are the potential risks or side effects of restarting only appian_services_stop? Could this lead to instability or partial recovery? Is there any known impact on data integrity, indexing, or service coordination? Appreciate any insights or experiences you can share. Thanks,

Hello Community, Recently, our Appian environment was experiencing performance slowness. To address this, we executed the command: appian_services_stop / appian_services_start After doing so, the system came back up and was running fine with improved performance. Later, when our vendor connected, they insisted that we should only follow the manual stop order described in the documentation: 1. Stop application server 2. Stop search server 3. Stop data service 4. Stop engines They blamed our use of appian_services_stop for later issues. However, when they followed the manual stop/start sequence, the system failed to come back online and has remained down since then. My question is: Is there any risk or problem associated with using appian_services_stop / appian_services_start instead of manually stopping/starting in order? Thanks in advance for clarification.

We got record sync failure for all Record type enable for sync after Appian Upgrade and then we need manually sync the records. Is there any bug on this? Ideally Appian upgrade process should not have post upgrade activity of Record sync.

Hi Team, While upgrading Appian server to 24.3, after installation at the time of starting search server  I have received this error :- [WARN ][com.amazonaws.auth.profile.internal.BasicProfileConfigFileLoader] [localhost] Unable to load config file nulljava.security.AccessControlException: access denied ("java.io.FilePermission" "/cs/appian/.aws/config" "read") ERROR: Elasticsearch did not exit normally - check the logs at /ps/appian/appian/logs/search-server/appian-search-cluster.log Elasticsearch died while starting up, with exit code 1 Thanks in advance.

We recently upgraded Appian from version 25.1 to 25.3, performed some testing, and created new objects in the latest version. Now, we want to revert to version 25.1. However, we did not take a backup before the upgrade.Is it possible to restore the previous version without a database backup?When attempting to downgrade to 25.1, we are encountering data synchronization issues during Tomcat startup.As a workaround, can we manually revert individual object changes and delete the newly created objects before downgrading?Please share your suggestions. Your input is much appreciated.

Hello, the truth is that the problem I have may sound very strange, but it is something related to Google Maps or the plugin. It happens that the map freezes, here I will leave my code and explain exactly what it does, the first thing is a pickerFieldCustom in which the user will enter an address close to their house and that address calls the Maps API to recommend addresses and then when selecting an address, the service is used to bring the latitude and longitude, it is here that this data is passed to the component that displays the map and where it seems to freeze. a!localVariables( local!data: {}, local!coordenadas, { a!cardLayout( contents: { a!pickerFieldCustom( label: "Direccion de Asistencia", suggestFunction: rule!CT_autocompletarDireccion(address: _), selectedLabels: local!data, value: ri!registroSiniestro.direccionAsistencia, saveInto: { local!data, ri!registroSiniestro.direcci

Hi  I want to automate Appian server stop process. If I am starting or stopping Tomcat Server can we get the status of it as we get for other servers ? ( Not in tomcat-stdout log ) Thanks in advance .

Hi, Did all steps 2-3 times not sure what am i missing at step 5 application build for "W2375SAA Vehicle" Generate environment record types is not accessible.   choose Database Table I see below Can some one look into this. looking forward to do next steps and learn more.  Thanks, Ami 

can anyone help me as to how to get access to admin console my community account is somehow set to basic user and I am not able to change the setting to system administrator

Hi Community, We’re planning to upgrade our on-premise Appian environment from version 23.3 to 25.3. Based on the official documentation, it appears that a direct upgrade isn’t supported, and we’ll need to follow a sequential path: 23.3 → 25.1 → 25.3. I’d appreciate any insights on the following: Is this sequential upgrade path (via 25.1) the recommended or most stable approach? For those running Appian in a High Availability (HA) setup, how did you manage the upgrade across multiple instances? Were there any challenges or performance impacts during the production upgrade, especially related to backup/restore of large volumes of data? Any lessons learned or best practices you’d recommend to ensure a smooth upgrade? Thanks in advance for your guidance and experiences! Best, Ramanji

Hello, We recently upgraded our Windows Server from 2016 to 2022. The Appian version remained the same at 24.1, and the Appian home directory is still at D:\Appian. We did not make any changes within Appian itself. The database server, MS SQL Server, was also upgraded from 2016 to 2022. After the server upgrade, the Appian engines and Tomcat application server started successfully. However, images are not loading on the sites. When I checked the logs, I found the following error related to this issue.I did the Test connection for DB in Admin console and it was successful.Any suggestion to resolve this issue?

I want to know if there is anyway can compile appian code in local? Or use git to manage the source code.(Source code not the package download from web). What problem we face is how to develop in parallel。we are a huge team (100 developers). When we develop a new function,  we usually need to use the same object. But appian can not develop in parallel. So we want to find if there is any way we can compile appian code in local.

I'm hearing that Appian does not accept passwords that are 22 characters long. What is the maximum length for the password of an Appian user account? Is this published officially anywhere?  (I did not see it on the Administration Console documentation page.) Thank you.

Hi All, We want to understand more on the Maintenance Downtime Calendar in Appian.As we receive downtime emails in advance for maintenance of the site (for upgrade or any other thing).Also The timing and date can also be accessed from MyAppian Forum site.But these two things would only be accessible by few people in the org/site (support contacts).We want to notify other Appian users about the downtime scheduled so they can be prepared and resume their work accordingly.We are able to think on following ways:1. The Team who has the access will check and update us. 2. They will sent out an email to the Appian users explicitly about the downtime.But all of this would require manually checking the mail or the Appian Forum site. Is there any other way around that we can notify the user about it in advance so that they don’t lose their work. Kindly let us know if there is any other way to achieve this apart from the above.Thank you!

Hi Everyone, I am trying to understand how the internal messaging service and Kafka Zookeeper work in Appian .I am trying to figure out what impact it would have if Kafka goes down on one of the nodes in a 3 node cluster due to storage issues or some other reason. One thing I can guess is that the application's performance might decrease, and writes to the data service could also be impacted. Are there any other potential issues that could arise? Thanks                                                           Udhaya

Hello, I have a on-premise installation with some Web API Authentication -> Third Party OAuth 2.0 Clients configured. However, we discovered that the JWKS Public Key file was removed, apparently directly from the server, as when trying to open them I'm getting the following error that for security reasons I cannot add any screenshots of: Error in a!forEach() expression during iteration 1: Expression evaluation error at function fn!content_appian_internal [line 40]: Invalid Content ID. I wanted to identify in the server where these configuration are being stored and if it's possible to restore the deleted file somehow, the only option for the moment is to delete the configuration and manually add it again. Also, I'd like to locate the root cause, just in case there's an automatic process running in the server making these deletions to prevent it from happening again. Thank you

Hi all, We have just upgraded Appian from 23.3 to Appian 25.2 and when starting Tomcat we have found the following error in the log: [PUT], host [http://localhost:9200], URI [/user-activity-8-0/_settings?master_timeout=30s&timeout=30s], status line [HTTP/1.1 401 Unauthorized] {"error":{"root_cause":[{"type":"security_exception","reason":"unable to authenticate user [appian] for REST request [/user-activity-8-0/_settings?master_timeout=30s&timeout=30s]","header":{"WWW-Authenticate":["Basic realm=\"security\", charset=\"UTF-8\"","ApiKey"]}}],"type":"security_exception","reason":"unable to authenticate user [appian] for REST request [/user-activity-8-0/_settings?master_timeout=30s&timeout=30s]","header":{"WWW-Authenticate":["Basic realm=\"security\", charset=\"UTF-8\"","ApiKey"]}},"status":401} at org.elasticsearch.client.RestCli

What are the steps involved to migrate appian from on-prem to cloud.

A client reported that one of their processes has been quite slow. Their process relates to a Wizard style interface that the user needs to populate before submitting the task. However, the interface does not perform any heavy queries or expressions. When reviewing the Health Check report, what should you do? Ans:- a.Investigate the slow activity-chained process flows (as multiple User Input Tasks might be linked together) and merge these into a single interface b.Investigate the number of unattended process loops (as multiple User Input Tasks might be linked together) and merge these into multiple node instances where possible c.Investigate the interface size and review the historical performance trends of the interface (as it might indicate an environment issue) and make adjustments where necessary

Hello All, After upgrading to Appian 25.2, we noticed that deployments triggered via the deployment-management/v2/deployments API are taking significantly longer to complete. Previously, the same deployment process would finish in around 8 minutes, but now it takes over 3 hours. From the Tomcat logs, we observed errors related to constant updates during the deployment process, which may be contributing to the delay. We also attempted to stop the in-progress deployment by restarting application servers and engines, but the deployment continues to remain in-progress and is not cancelled. We have already raised a support ticket with Appian, but in the meantime, checking with the community: Has anyone else encountered similar issues after upgrading to Appian 25.2? Is there any other way to cancel or forcefully terminate an in-progress deployment initiated via the API? Thank You, Sneha.

Can we configure Appian Cloud so that a specific Site (e.g. https://<mydomain>.appiancloud.com/sites/customer) is publicly accessible from outside our corporate network, while restricting access to the Design environment, Admin console, and other internal Sites to only whitelisted IP addresses?

Hello Team, Our Appian platform is on Cloud. Does anyone know how to download the Identity provider metadata file that has configured for SAML Authentication?  We want to update the saml end points for the certificate renewal. Thanks, Ramesh

I need assistance resetting a user’s password in our Appian environment. Due to security restrictions, we do not have SMTP/email functionality available, so the standard “Forgot Password” workflow cannot be completed.  Current Behavior I navigate to the Administration Console → Users Locate the user record for John Doe Click “Reset Password” System prompts that a reset email has been sent No email is sent because SMTP is disabled

Hello, We have moved from version 24.4 to the new 25.1 and we have encountered some errors in interfaces. The gridFields that were in version 24.4 had a RecordData as data collection in which they were configured with some Fields with relationships a!recordData( recordType: recordType!example, fields:{ recordType!example.example ... }) Now in version 25.1 the interface is broken because the action records have lost their ID To fix it, we added the base field recordtype!exxample.id to the field so that it obtains the data since it gave an error and the action link did not appear. a!recordData( recordType: recordType!example, fields:{ recordType!example.id  <----- recordType!example.example ... }) Is there any explanation for this? Thank you
