ABAP Proxy Set up and Load balancing

[Former Member]

Hi All,

We have a SAP ECC 5.0 PRD server in our landscape. I need to set up ABAP Proxy in the server.

They have implemented Load balancing in the ECC 5.0 PRD server. They have two servers (One Central Server and another APP Server) and one of the servers will be used at any point in time based on load conditions.

Now where exactly i have to perform the ABAP Proxy set up and how does it work at runtime.

Thanks in advance.

Hey,

refer to this.

R3 side

SLDCHECK

Use this transaction to access the SLD of XI.

SLDAPICUST

Create an entry for respective XI server

requires hostname, port username and ip.

Can have multiple enteries for different servers.

But you can check only one entry.

based on the entry that is checked, respective SLD API will be triggered from

SLDCHECK.

SM59 (T type connections).

To connect to the SLD you need 2 types of TCP/IP connections.

1)LCRSAPRFC:-

In this you require the gateway host(ip address) and gatewayservice(sapgw[system no.])

YOu also need to give Program ID.

Entry of corresponding Program ID must be maintained in SMGW.

IN SMGW Click GoTo->logged on Clients.

If entry is not there for corresponding XI.

Create a communication channel in XI, pointing to R3 and give a Program ID

in the channel. Once the channel is activated, corresponding Program ID wil

appear in SMGW.

2)SAPSLDAPI:-

In this case follow the same porcedure as for LCRSAPRFC.

As far as the Program ID is concerned te procedure mentioned above is for

Customized RFC's

The RFC destinations mentioned here are both standard RFC's

Hence for these two RFC's no need to Create Program ID's. you just need to

change the System ID of the Program ID.

Both these RFC's are maintained in the J2ee server of XI.

SPROXY.

In this transcation you can check the Proxies.

If the proxies are not activated (i.e. if the message interfaces are not active)

this step is optional

then you need to maintain one G type RFC destination pointing the resepctive XI server.

In the G tpye RFC destination give the Ip adress of the XI server in the target

host and set the path prefix as /rep.

Goto SPROXY->Goto->connection test-> click on the table SPROXSET.

In this table maintain enteries for ADDRESS_ONLY_FROM_SPROXSET and IFR_HTTP_DEST

The values corresponding to these enteries will be the G tpye RFC destination.

In order to connect R3 to the Integaration server you need to maintain H type

The default RFC is XI_INTEGRATIONSERVER. In you need to give the Target host entry as the

Ip address and Path Prefic as.../sap/XI/engine/?type=entry (this you can get from SXMB_ADM of XI)

You can also create the H type RFc of your own.

goto SXMB_ADM(r3) and open Integration engine configuration.

Milan

Hi Sachin,

Thanks for your prompt reply.

Before I search SDN, may i request you to read my post carefully.

I did not ask how to set up ABAP Proxy. My question was to where exactly i need to set my ABAP Proxy if I had two R/3 servers due to load balancing.
