5. Restart Websphere Partner Gateway.
Document Manager workload
The number of processing threads used can be configured for several
subcomponents by setting system properties. The default values for these
properties are low but they might have been modified by the administrator. Look
for properties involving thread configuration in the configuration tables in
"Appendix C - component-specific system attributes" on page 223.
Document structure
Large documents can come either from the external partner or the internal partner
(backend application). Determine if there are ways to reduce the document sizes,
such as reduced batch sizes or using smaller documents.
Increasing the heap size
About this task
Whenever sending a large number of documents (approximately 40) that have a
size of 50MB with encryption, signing, and compression over AS3, it is necessary
to increase the heap size. If the heap size is not increased, documents can fail with
the error OutOfMemory.
The OutOfMemory error is the result the working memory not being sufficient for
the Websphere Partner Gateway to route the documents in bulk. Therefore, it is
recommended that you increase the heap size. To increase the heap size parameters
for the DocMgr server, perform the following steps:
1. Log into the WebSphere Application Server admin console.
2. From the WebSphere Application Server admin console, select java and process
3. Set the initial heap size to 1024.
4. Set the max heap size to 1536. If the system has more than 2GB, then max heap
Collating data for multiple languages
WebSphere Partner Gateway depends on the underlying databases for collating
data. If your installation supports multiple languages and your Unicode data is not
sorted correctly, review this section.
DB2
Since version 6.0, WebSphere Partner Gateway configures DB2 to use the
UCA400_NO collating setting. DB2 version 8.2 does not support all special cases
(as described in Unicode Standard version 4.00 Technical Standard #10) for all
languages. In these instances contact DB2 directly.
