CAU fails on Tomcat with UploadSizeExceededException

Products

• CA Automic Workload Automation - Automation Engine

Issue/Introduction

CAU for Linux Agent to fails with:

Runtime Error in Object '' Line '&02': Converting String to numeric Value not possible. String '&04'

However, the root cause is found in the Tomcat log: UploadSizeExceededException.

Cause

This is due to a Tomcat limitation.

Resolution

Add the following in web.xml:

<multipart-config>
   <max-file-size>104857600</max-file-size>
   <max-request-size>104857600</max-request-size>
   <file-size-threshold>0</file-size-threshold>
</multipart-config>

If this does not solve the issue, you should update server.xml and set maxPostSize:

https://tomcat.apache.org/tomcat-10.0-doc/config/http.html

This is set within the connector definition and would look something like this:

<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
    keyAlias="tomcat" keystoreFile="<Automic>\certificates\tomcat-keystore.jks" keystorePass="tomcat"
    maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
    clientAuth="false" sslProtocol="TLS" maxPostSize="104857600"/>

In general, 100 MB => 104857600 should be enough but it is possible to set 200 MB => 209715200 to have an extra margin.
