The following error is also seen in the application server logs:
16:29:55,598 INFO [stdout] (ServerService Thread Pool -- 83) 2018-04-04 16:29:55,598 [ServerService Thread Pool -- 83] ERROR com.appiancorp.applicationpatch.PatchSchemaSpringContextListener - APNX-1-4506-001 - Failed to connect to data server. The ability to store and retrieve application patches will not be available until the connection is reestablished. Check the status of the data server.
The Appian data server is not running or is not available.
To correct this issue, perform the following:
<APPIAN_HOME>/data-server/bin/status.sh
status.bat
hs
hs-gw
rts-0
rts-gw-0
<APPIAN_HOME>/data-server/bin/start.sh
start.bat
Once the data server is started up, objects can be added to patches.
This only affects Appian 18.1.
