for the architects:
we are using ADS (adobe document services) for two purpase:
1) using "normal" ADS-functions as PDF-generation from SAP-BW and SAP-ECC systems
with RFC: ADS
see colour orange
2) using ADS-service from NWBC-sessions and WebDynpro-ABAP ALV listings to generate PDF
with RFC: SALV_WD_EXPORT_PDF
see colour red
because we expect much ADS and PDF-generation traffic, we try to realise this scenario with 2 (or more) ADS-server and loadbalancing (round-robin)
for the 1) kind of ADS-usage i will see no problem to realise,
we will use a virt.IP for hostalias ADSPRD pointing to the loadbalancer and the loadbalancer is doing round-robin to the first or to the second ADS-server.
but the 2) szenario with RFC: SALV_WD_EXPORT_PDF and PGM-ID how to realise for that szenario a loadbalancing ???
we configured both ADS-server JCo with identically PGM-ID, both are connected to the ECC-sapgwnn, but with PGM-ID, the way from RFC-destin. SALV_WD_EXPORT_PDF with PGM-ID to the gateway will find allways the same ADS-server, there is no round-robin loadbalancing ?
? is loadbalancing possible for the 2) szenario ?
