Howto persist information in a pi module

[markus_schalk]

Hello experts,

is it possible and advisable to persist information in a local enterprise bean used in pi adapter module chain?

If yes, please give me information on how to do it. Code examples are appreciated.

Thanks in advance!

Kind regards,

Markus

Hi Markus,

                 you can read from/ write to files from within  adpter module code. The files will recide under folders of PI server.

Hi Markus, I have not tried this, but perhaps your modules can read/write to an adapter variable as explained in this blog by Jin:

I did this kind of requirement but not using adapter module,as per my experience implemnting through adapter module not a right idea,

1)Suppose your receiver is SOAP and you want store the message in Oracle table, this case your adapter module should support sending data to Data base .

you need to maintian the sequence also in Adapte module chain.

This is bit tedious activity that why add one more JDBC receiver adapter  and insert data.

I dont recommend file storage domain.

Another approach is use file as a storage media. You can easily do File lookup using UDF during mapping.  You might want to check this wiki about file lookup using UDF. This is very simple approach.

Hi,

I don't think so - why not

a) store the data in some jdbc table and populate it with an normal PI adapter

as a second receiver in your flow ?

b) - just read the data in the module

Hi Markus,

In this wiki you have an example of a module implementation with access to the payload:

Another example:

For the persistence you could use a Z table in the abap stuck, or create a table in the java stuck (i never try this option and i cant assure you the problems that you can find) http://scn.sap.com/docs/DOC-1222
