poolSize
Multiexcerpt
MultiExcerptNamepool_size

Runtime 2015.10 Supply the maximum number of parallel connections to the SAP system.

  • The pool size can be defined per connection string. If you have multiple aliases with the same connection string, the highest value will be used.
    The same applies, if you set the values in the SAP adapter settings on the Bridge.

  • If this tag is not set, the connection pool size specified on the <<E2EComposite>> will be applied.

  • Compatibility note: This tag will not be created for existing aliases in older models. You have to add the tag manually if you want to set it.
    Older xUML Runtimes (before version 2015.10) will not start with the setting being present. As a workaround, you can delete the tag value.

If all connections from the SAP connection pool are in use, warnings will be logged to the transaction log each second a service is waiting for connection.

In this case, increase the pool size to solve the problem.

sapTrace

The effect of this flag being true is two fold:

  • First, the SAP RFC libraries will write trace file information (.trc) into the directory the service has been deployed to.

  • Second, by using the SAP transaction *SMGW (SAP gateway monitor) we can monitor the dataflow from and to the gateway the server is registered on.

The SAP trace level has to be defined in tagged value connectionString. See Client Connection Options for a list of the allowed trace level values.
