Attach multiple files to a catalog request

Products

• CA Service Catalog

Issue/Introduction

When trying to attach two files at the same time to a catalog request, then clicking submit, the attachment files are not attached and there is no error message

Environment

Service Catalog 17.3.x and 17.4.x

Cause

The root cause was that the combined size of the files, over 8 MB, is more than the maximum POST size that Tomcat is currently configured to accept.

That value, 'maxPostSize', is set to a default value of 5242880 bytes, or about 5.24 MB.

As such, attaching only one file was ok because its size was under 5.24 MB.

But attempting to attach both at once exceeded this limit and caused Tomcat to stop processing their submission.

Resolution

The resolution is to increase the value for 'maxPostSize' in web.xml per your business needs.

Our recommendation is the following:

1) Locate the file  USM_HOME\view\webapps\usm\WEB-INF\web.xml

2) Make  a backup of the existing web.xml  first . Then, locate the following section in web.xml :

<init-param>

<param-name>maxPostSize</param-name>

<param-value>5242880</param-value>

</init-param>

In the 'param-value' attribute, you can update the value to a greater number, for example 20 MB or 50 MB, per your business needs. 

If you submit multiple files in a request at the same time, the combination of the file size of all those files cannot exceed the value specified here.  

Please note that this value will need to be specified in bytes.

3) Then restart the Service Catalog services and you should be able to attach these two files to a Request as long as the two files sizes do not exceed the limitation specified in web.xml.
