Administration

Hello: I am seeking advise for vertical scaling of a single server, in regards to adding more engines in the appian-topology.xml configuration. We are currently running the default topology with three analytics and three execution engines. Our server have 16-CPU cores and 64GB of RAM, and I am looking for suggestions on how may engines would be ideal for this given system CPU and RAM. We are looking to support 100 active users at any given time. Is there a formula for scaling to number of engines relative to system specs; or of you can share any use case examples or example of topology with similar system specs would be greatly appreciated. TIA.

we have deployed Appian in onpremise. System logs navigation menu is missing. Updated the user as System Administrator. Still unable to access the logs. How to access log files in interface or using objects?

Post upgrade to Appian 22.1 process model is not showing write to data store and news feed smart services. Also getting invalid process message.

a!columnsLayout( columns: { a!columnLayout( contents: { if( isnull(local!exportDocId), /*This link field contains the link that starts the export*/ a!richTextDisplayField( labelPosition: "COLLAPSED", value: {a!richTextIcon( icon: "file-excel-o", color: "#6aa84f", size: "MEDIUM" )," ", a!richTextItem( text:"Export Customer Report to File", link:a!dynamicLink( label: "Export to Excel File", saveInto: { a!exportDataStoreEntityToExcel( entity: cons!FS_ORDER_ENTITY_POINTER, documentName: "Excel Export " & now(), saveInFolder: cons!FS_constant, onSuccess: a!save( local!exportDocId, fv!newDocument ), /*This displays an error if there is an issue executing the the save*/ onError: a!save( local!errorMessage, "Error Exporting File to Excel" ) ) } ), size: "STANDARD" ) } ), {} ), a!linkField( labelPosition: "COLLAPSED", links: a!dynamicLink( label: "<<<Back", value

When we try to do a cleanup older versions of an object which has say about 500-2000 versions in a document or an UI expression, it so happens that the object/document appears in environment but is unavailable to view details or refer the details back. This has been observed in Appian 22.1 and has occurred couple of times in our Dev environment. We have luckily a deployment on previous day and was able to recover the UI expression by importing the package from higher environment. However, for the document, we had a similar file with same uuid and ID and unable to delete it.  Why does the deletion of versions delete the objects? Why do we see duplicates in terms of document that doesn't exist?

We're facing an issue where all URLs with a certain string contained within them are blocked no questions asked for security purposes. It just so happens that the URL of a particular record instance in PROD has the magic letters in order against quadrillions of chances, and it's now blocked so users can't access the record. Is there a way to change the URL that's generated for that particular record, such as changing the ID of the record?  Should we try reimporting the record, or is it likely to wind up with the same ID?

In the past if an Appian object was currently open during an import then the import would fail. It seemed that this was resolved many versions ago, allowing the import to go through without issue. In the most recent version it seems to have come back, and imports now error out if an object is open. Has anybody else experienced this? This seems to be a step backwards in capability.  

Hi All, I have tried to configure Both SAML authentication and login authentication for an url. Allowing some users authenticated using SAML and others using Login page.

Hi Folks. I am New to Appian installation in my local desktop. I have configured each of the step as mentioned in Appian Quick start guide for windows machine. When I am starting the engine getting this log continuously and it's not progressing ahead. Can anyone guide me is it due to temporary license that I need to get in ? If so how can I get it for my own POC work.

We are trying to build an audit report for overall sites usage at environment level. In the sites_usage.csv file we can see that all the page types(action, record type and reports) are getting audited but not interface type. Is it something Appian missed to audit in the sites_usage.csv or this is something which can not be achieved?

Hi, In my Linux server with appian 20.4 installed,  the following are the details in the "profile" file in /etc folder --export JAVA_HOME=/data-01/appian/203/appian/java ---- actually this path does not exist in the serverexport PATH=$JAVA_HOME/bin:$PATH: But when I run the command  echo $JAVA_HOME, I find this -- /usr/lib/jvm/jdk1.8.0_191 I tried removing the  java folder, in the above path(/usr/lib/jvm/jdk1.8.0_191) and stopping my Appian services, (firstly the Tomcat) but the jsp commands are unrecognisable. As soon as I restored the Java at the above path, everything resumed fine. The JAVA_HOME in the profile file refers to a different path while the actual JAVA location used by my services seems to be different. Can any one guide me to change the JAVA_HOME path? Can I point my Appian services to use the the Java in this path (/data-01/appian/204/appian/java)? If so where should I set the path for my Appian services to point to this path? Thanks, Chetana

Hello community, Context: We have an application (eg.: APP Groups) to manage the security for a second application  (eg.: APP Application) with all the necessary groups. Our team have a requirement to allow the user to create a group without having to access the Appian Designer, so we are using the "create a group" smart service (https://docs.appian.com/suite/help/22.1/Create_Group_Smart_Service.html). Problem: This smart service works but it doesn't allow us to add the object in the groups application. There is any way to, when creating a group, passing the indication (through smart service or function, for example) that this group is to add to the group application? We need to be able to move this objects through environments, so they need to live inside this application. Thank you.

Hi All, Just wanted to know if we can provide a Basic user access to the Admin console or should the user be a System Admin only to access the same? Thanks and Regards, Sumit Kumar Jha

E-mail notifications are quickly driving everyone in our team crazy. While I can think of some workarounds, before I go about implementing that, I was wondering if there was any built in functionality to configure a sort of end of the day digest e-mail for any of the following: - user input task notifications - error messages - emails from the send email smart service

Hi, I am managing multiple Appian environments and would like to know how I can monitor license usage for each environment separately. Within each environment, I also need to monitor license by user group and license type. Curious to know how others have approached this problem in the past. Thoughts? Thanks!
