As part of setting up Active Spaces clustering with TLS as in documentation below, we have to create a policy file.
https://docs.tibco.com/pub/spotfire_server/7.11.0/doc/html/TIB_sfire_server_tsas_admin_help/GUID-307A9023-DEE2-4427-A40F-FCAB82398415.html

When you try to run the following commands to create a as-policy.txt file, it may throw errors as shown below:
*************************************************************
as-admin> create security_policy policy_name "as-policy" policy_file "as-policy.txt" encrypt false
SYS_ERROR (action_failed -
    Failed Command: create security_policy policy_name "as-policy" policy_file "as-policy.txt" encrypt false

This article talks about the errors encountered while setting up ActiveSpaces clustering with TLS enabled on Spotfire Servers

The errors are due to a missing as-common.jar file in the Spotfire Server install folder. Copy the as-common.jar file to the WEB-INF\lib folder on each Spotfire Server in the cluster to resolve this issue.
