[jboss-user] [JBoss jBPM] - Re: BPEL GA on Oracle: ElementType causing problem while run

[alex.guizar@jboss.com]

For the sake of isolating the error, can you reduce the column length to 2000 (the max size for a RAW column), repackage and redeploy the application?

If downsizing causes the data to exceed the column length, locate the following entry in jbpm.cfg.xml and set it to a value greater than 0. Note that changing this setting has the side effect of enlarging small byte chunks (say, 100-200 bytes) so use it with care.
<!-- see java.util.zip.Deflater for details on the compression level -->
  | <int name="jbpm.bpel.element.deflate.level" value="0" singleton="true" />

Anywhere you see length="4000" in the mapping documents, we mean "arbitrary length". For both jPDL and BPEL we'd have really liked to use BLOB/CLOB instead of VARBINARY/VARCHAR column, but support for the former varies greatly from vendor to vendor.

In 1.1.Beta3, the length was not specified, which resulted in the database picking a default length. In some cases the default was as small as 255 chars/bytes, which was unacceptable. Unfortunately, it is hard to pick a value that works for all databases, drivers, versions, etc.
