JCO RFC destination
一：登陆PI的GUI，进入事物SM59，创建T类型RFC destinations如下：
AI_RUNTIME_JCOSERVER ：used for the mapping runtime, value mapping, and the exchange profile
AI_DIRECTORY_JCOSERVER： used to refresh the runtime cache
LCRSAPRFC ： required for the connection to the SLD，used to read the exchange profile
SAPSLDAPI : required for the connection to the SLD , used by the ABAP API
详细的步骤如下：
1. Log on to your Integration Server host.
2. Call transaction SM59.
3. Choose Create.
4. Enter at least the following:
○ RFC destination: AI_RUNTIME_JCOSERVER
○ Connection type: T
○ Description: <your description>
5. Choose ENTER.
6. Choose the Technical settings tab and do the following:
a. Select Registered Server Program.
b. In the Program ID field, enter: AI_RUNTIME_<SID>
<SID> is the SAP system ID of your Integration Server host.
Use uppercase letters only.
c. Enter Gateway host and Gateway service of your Integration Server host.
To find out the required parameters:
...
i. On the Integration Server host, call transaction SMGW.
ii. Choose Goto ®Parameters ® Display (see entries for gateway hostname and gateway service).
7. Choose the Special Options tab and select the Unicode flag in the Character Width in Target System box.
8. Save your settings.
9. Repeat steps 3 to 8 for the remaining destinations:
○ AI_DIRECTORY_JCOSERVER
Program ID: AI_DIRECTORY_<SID>, where <SID>is the SAP system ID of your Integration Server host.
○ LCRSAPRFC
Program ID: LCRSAPRFC_<SID>, where <SID> is the SAP system ID of your Integration Server host.
○ SAPSLDAPI
Program ID: SAPSLDAPI_<SID>, where <SID> is the SAP system ID of your Integration Server host.
10. Leave transaction SM59 open for later tests
二：配置JAVA中的JCO，既注册SM59中的program ID
1、在浏览器的地址栏输入
<host> and <HTTPport> 是Integration Server的主机名和端口号，主机名在gui的右下角，端口号通过事务码SMICM，Goto ® Services 中HTTP的端口号
2、选择SAP NetWeaver Administrator->Configuration Management->Connectivity->Jco RFC Provider
在这个页面点击create，enter Gateway Host，Gateway Service，Server Count（值设置为10），next，在Repository configration中
Enter the parameters for the Integration Server host: Application Server, System Number, Client, and Language username ，password，
note：可能PI/XI版本的不同，路径也不通 （如：1. On your Integration Server host, start the J2EE Engine Visual Administrator.
2. Choose Cluster ®Server®Services ®JCo RFC Provider.）
3 、一直next，最后finish
4. Repeat steps 2to 3 for the remaining destinations:
○ AI_DIRECTORY_JCOSERVER
Corresponding values from transaction SM59
Number of processes: 10
○ LCRSAPRFC
Corresponding values from transaction SM59
Number of processes: 3
○ SAPSLDAPI
Corresponding values from transaction SM59
Number of processes: 10
最后测试
Test the RFC Destinations
After you have maintained all RFC destinations in both the ABAP and Java environments, you can check all the connections above as follows:
1. Call transaction SM59 again.
2. Open your RFC destination.
3. Choose Test Connection.
No errors should be displayed.
