Current Revision posted to Appian Knowledge Base by Parmida Borhani on 10/14/2019 12:48:48 AM

Symptoms

Swim lanes disappear in a process model, and horizontal connectors display as diagonal connectors upon opening the process model. This change is depicted in the screenshots below:

In addition, the application server log prints one of the following error messages:

"Access is denied" error:

ERROR com.appiancorp.process.design.service.ProcessDesignServiceXmlImpl - An error occurred retrieving the model from the filesystem.
java.io.FileNotFoundException: <APPIAN_HOME>\_admin\models\<XXX>\<PM_UUID>\draft.xml (Access is denied)

"The system cannot find the path specified" error:

ERROR com.appiancorp.process.design.service.ProcessDesignServiceXmlImpl - An error occurred retrieving the model from the filesystem.
java.io.FileNotFoundException: <APPIAN_HOME>\_admin\models/<XXX>\<PM_UUID>\draft.xml (The system cannot find the path specified)

"No such file or directory" error:

ERROR com.appiancorp.process.design.service.ProcessDesignServiceXmlImpl - An error occurred retrieving the model from the filesystem.
java.io.FileNotFoundException: <APPIAN_HOME>_admin\models/<XXX>\<PM_UUID>\X.0.xml (No such file or directory)

Note: if you are using Appian 7.11 or earlier and experience the issue depicted in the above screenshots, and the application server log prints a different error message, please reference KB-1001.

Cause

The process model's most recent XML file, draft.xml, is not accessible in the filesystem (it is locked, the shared folder is unavailable, or the application server does not have the correct permissions to access it).
The process model's most recent XML file, draft.xml, has been deleted from the filesystem.
The process model version you are trying to access has a corresponding XML file that is either locked, deleted, or the application server does not have the correct permissions to access it. Removing process model XML files from the filesystem of your site with the Process Model Utilities plugin can cause this behavior for specific versions of your process model.

Action

Ensure that the draft.xml file is unlocked and that the appropriate folders in the <APPIAN_HOME>\_admin\models shared directory are accessible. In addition, ensure that the user that is running Appian has appropriate permissions on the draft.xml file. To prevent this issue in the future, do not virus-scan or back-up the models folders during business hours.
Restore the XML file from a back-up. To prevent this issue in the future, do not delete XML for models directly from the filesystem.
If using the Process Model Utilities plugin, adjust PM Cleanup Settings in order to preserve XML files associated with process model versions that will still need to be accessed.

Affected Versions

This article applies to Appian 16.1 and later.

A process model that used to have swim lanes and/or straight connectors now has no swim lanes and diagonal connectors. This is depicted in the screenshots below:

In addition, the application server log prints one of the following three error messages:

Error 1:

ERROR com.appiancorp.process.design.service.ProcessDesignServiceXmlImpl - An error occurred retrieving the model from the filesystem.

java.io.FileNotFoundException: <APPIAN_HOME>\_admin\models\<PM NUUMBER>\<PMUUID>\draft.xml (Access is denied)


Error 2:

java.io.FileNotFoundException: <APPIAN_HOME>\_admin\models\<PM NUUMBER>\<PMUUID>\draft.xml (The system cannot find the path specified)


Error 3:

<Insert error here>

Cause

Error 1: The process model's most recent XML file, draft.xml, is not accessible in the filesystem (it is locked, the shared folder is unavailable, or the application server does not have the correct permissions to access it).
Error 2: The process model's most recent XML file, draft.xml, has been deleted from the filesystem.
Error 3: There is a mismatch between the process design and the filesystem. This can happen when the environment engine database KDB file for design (pd*.kdb) has been reverted to a previous date. In this case, the older KDB file will not include the most recent transactions performed on the process model. This will cause a mismatch between the pd*.kdb file and the draft.xml file.

DRAFT KB-XXXX Process model swim lanes disappear and connectors become diagonal

Revision 14 posted to Appian Knowledge Base by Jordan Horwat on 4/30/2018 5:43:49 PM

Symptoms

A process model that used to have swim lanes and standard vertical/horizontal connectors now has no swim lanes and diagonal connectors. This change is depicted in the screenshots below:

In addition, the application server log prints one of the following three error messages:

"Access is denied" error:

ERROR com.appiancorp.process.design.service.ProcessDesignServiceXmlImpl - An error occurred retrieving the model from the filesystem.
java.io.FileNotFoundException: <APPIAN_HOME>\_admin\models\<XXX>\<PMUUID>\draft.xml (Access is denied)

"The system cannot find the path specified" error:

ERROR com.appiancorp.process.design.service.ProcessDesignServiceXmlImpl - An error occurred retrieving the model from the filesystem.
java.io.FileNotFoundException: <APPIAN_HOME>\_admin\models\<XXX>\<PMUUID>\draft.xml (The system cannot find the path specified)

Mismatch:
```
Insert error code here.
```

Note: if you are using Appian 7.11 or earlier and experience the issue depicted in the above screenshots, please reference KB-1001.

Cause

The process model's most recent XML file, draft.xml, is not accessible in the filesystem (it is locked, the shared folder is unavailable, or the application server does not have the correct permissions to access it).
The process model's most recent XML file, draft.xml, has been deleted from the filesystem.
There is a mismatch between the process design and the filesystem. This can happen when the environment engine database KDB file for design (pd*.kdb, located at <APPIAN_HOME>\server\process\design\gw1) has been reverted to a previous date. In this case, the older KDB file will not include the most recent transactions performed on the process model. This will cause a mismatch between the contents of the pd*.kdb file and the draft.xml file.

Action

Ensure that the draft.xml file is unlocked and that the appropriate folders in the <APPIAN_HOME>\_admin\models shared directory are accessible. In addition, ensure that the user that is running Appian has appropriate permissions on the draft.xml file. To prevent this issue in the future, do not virus-scan or back-up the models folders during business hours.
Restore the XML file from a back-up. To prevent this issue in the future, do not delete XML for models directly from the filesystem.
Copy the most recent checkpointed pd*.kdb file from <APPIAN_HOME>\services\data\archived\process-design to <APPIAN_HOME>\server\process\design\gw1 and rename it so that it is numbered higher than any of the KDB files in the <APPIAN_HOME>\services\data\archived\process-design directory. Delete the other KDB file in <APPIAN_HOME>\server\process\design\gw1 so that the file that was just copied over (and renamed) is the only existing file in the directory. To prevent this issue in the future, do not revert to a previous pd*.kdb file without the help of Appian Support.

Affected Versions

This article applies to Appian 16.1 and later.
