Agent in SQL Server 2016, running on Server 2014. SSIS project developed in VS 2015, runs as expected. Single node executes simple SQL. Package is deployed via DeploymentManifest, deployed to ‘SQL Server’. Deployed package runs as expected when started in Integration Services > Deployed Packages > MSDB
Have created Credential and Proxy, no changes to problem, no error messages, nothing logged. Run without Credential and Proxy, same outcome. Package Security ProtectionLevel is EncryptSensitiveWithPassword, have tried other ProtectionLevels with same outcome.
It appears that nothing is even beginning to execute, no error messages, no completion. How to check that package is actually deployed and agent can access?
