SAP JCO x JCO capabilities

[Former Member]

Dear All,

We are deploying the GRC AC and we saw the following line in the configuration guide:

SAP GRC Access Control 5.3 gives you the option of setting up SAPJCo connections instead

of JCo (adaptive RFC) connections. We recommend that you use JCos for your first 21

connectors because they are more efficient than SAPJCo connectors. If you need more than

21 connectors, use SAP JCos for the additional connections. We also recommend that you

use the 21 JCos for your highest volume or production environments.

Why SAPJCo connectors are more efficient than the JCos? What are the impacts I can have if I use a SAPJCo connector in a production environment?

Thks!

OK, I understood that part (sorry for my previous question).

My main concern is the effectiveness of the SAPJco versus the Jco connectors.

We are designing a solution to try to centralize different SAP system that are located in different countries to use 1 SAP GRC AC machine. If I add all necessary connections, it will pass the 21 connections limit stablished in the configuration guide.

In that case use the JCO connection facility available through content administrator as I said in the last post. If you do a search in SDN on GRC RAR configuration you will get many guides there.

Hi Oliver,

We also have a similar situation but relatively simple just because we do not use RAR for all our systems. The recommendation from SAP is to use the Adaptive RFC for the first 21 of your RAR connections and then use the standard JCO. BTW, this doesn't apply to CUP component as CUP connectors do not use Adaptive RFC connections.

So, if I create a logical system with 5 ECC environments, I will just need 1 SAPJCo and 1 JCo connectors?

Do not confuse logical system with connectors. They both are two different things. You will need 5 connectors (either SAPJCo or JCo) for 5 ECC systems.You can go with either SAPJCo or JCo connectors.

Let me answer this in a different way. When you have 5 ECC systems, you need to create a Logical system for the same with the 5 systems assigned to it. So you need to create 1 SAPJco connector for each ECC clients you want to connect. But if you use the connector type as Adaptive RFC then you can use the JCO connector defined in the Content Admin.

The logical system helps you to generate same rule set for all 5 ECC systems at a time against the Logical system name defined. My last post may may create few confusion on the same. Sorry for that.

Please let us know if you have any question.

SAPJco as you mentioned is the direct RFC connection from RAR to backend which is faster than JCO connections created from Content Administrator.

Whereas the JCO connections are more efficient for large landscapes. You need to define a Logical system where you will assign the similar kind of systems (ECC clients for e.g.) and connect with a adaptive RFC. This improves performance.
