In this blog we will see how customers can migrate from existing SLD to a new SLD via SAP Configuration Wizard. Changing all the SLD connections from existing SLD to new SLD manually will be time consuming and may miss few steps. SAP has provided a wizard to configure all the connections automatically. There may be number of reasons why they want to update SLD but some of them are:
My Current Landscape: PO Java Stack POQ (poqapp01), SLN (slnapp01) as existing SLD, SLQ (slqapp01) to be new SLD.
Prerequisites:
Pre SLD Changes Check in POQ :
1. Open POQ Process Integration Tools with url: http://<hostname:port>/dir/start/index.jsp
2. Click on System Landscape Directory. This will take you to existing SLD.
3. From POQ tools page --> Click on Administration --> Repository --> Aii Properties. We can see connections are currently pointing to slnapp01.
I just gave few screen shots to show currently POQ is connected to slnapp01 and once updated we will see the new sld details.
PreChecks in new SLD (slqapp01):
1. Now login into new SLD (http://<hostname>:port/sld) --> Technical Systems -->Under drop down Technical Systems type select Process Integration --> search for poq. If it is a brand new SLD it shouldn’t return any entries. If you copied the new sld from old sld via system copy or any other restore process then entries may exist, so go ahead and delete all poq entries.
2. Under drop down Technical Systems type select AS Java --> search for poq. It should not return any entries. If we have then delete them.
3. Now login into new SLD (http://<hostname>:port/sld) --> Business Systems --> search for poq. It should not return any entries. If we have then delete them.
Configure POQ to new SLD slqapp01:
1. Login into POQ --> NWA --> Configuration --> Security --> Destinations. Change the two existing HTTP destinations SLD_Client and SLD_DataSupplier to point to new SLD. Use user SLD_CL_POQ for SLD_Client and SLD_DS_POQ for SLD_DataSupplier which we created in prerequisites.
2. Now to NWA --> Configuration --> Scenarios --> Configuration Wizard --> Select PI AEX SLD Self Registration. If it is dual stack we need to select PI SLD Self Registration.
3. Click Start in above screen and enter Administrator user in the below screen and click Next.
4. Enter SLD_DS_POQ and SLD_CL_POQ user and password. Select configure new SLD and also specify new SLD details.
5. Select Next in the below screen. We already verified the below given points in our PreChecks above. Click Next.
6. Now the wizard starts and updates the connections. Few screenshots while it is updating are given below:
7. Once the wizard completes it gives the complete list of tasks it has executed successfully.
Post SLD Changes Check in POQ :
1. Open POQ Process Integration Tools with url: http://<hostname:port>/dir/start/index.jsp
2. Click on System Landscape Directory. This will take you to new SLD slqapp01.
3. From POQ tools page --> Click on Administration --> Repository --> Aii Properties. We can see connections are currently pointing to slqapp01.
Post Checks in new SLD (slqapp01):
1. Now login into new SLD (http://<hostname>:port/sld) --> Technical Systems -->Under drop down Technical Systems type select Process Integration --> search for poq. We should see the below entries.
2. Under drop down Technical Systems type select AS Java --> search for poq. It should return one entry.
3. Now login into new SLD (http://<hostname>:port/sld) --> Business Systems --> search for poq. It should return one entry.
With this all the SLD connections on POQ are pointed to new SLD. If we run into any issues some of them are discussed in note: 2034226 - Configuration Wizard: PI AEX SLD Self Registration
I saw lot of blogs on troubleshooting SLD or about inconsistencies. If we run into any of those issues best would be to rerun the above steps which will save time rather than troubleshooting the missing pieces.
- Current SLD is retiring quickly from Customers Landscape.
- An upgrade to SLD is planned so may be down for few days.
- A new SLD installed in the landscape.
My Current Landscape: PO Java Stack POQ (poqapp01), SLN (slnapp01) as existing SLD, SLQ (slqapp01) to be new SLD.
Prerequisites:
- New SLD is up and running.
- On new SLD slqapp01 user management create users SLD_CL_POQ, SLD_DS_POQ, PIAFPOQ, PIDIRPOQ, PIISPOQ, PIREPPOQ, PIRWBPOQ.
