Hi,

just want to know the main differences bet. abap-engine and java-engine as far as SAP Basis Administration is concerned!

I can do the basis admin on abap-engine but want to master the java-engine platform too! Will be pleased to hear from you.

The main difference is that one is based in ABAP and the other in JAVA...

Theres gazillions of pages of info here at SDN, also at help.sap.com and at SAP Marketplace... take you're time to read.

And now, i understand the real difference !

Main Diff.: One is driven by ABAP eingine, the other one is driven by Java connector !! So simple !

SAP writes a roman out of those two !!

Hi kumar,

Development environment of SAP is based on a fully integrated set of devtools functions pgmg lang and a data dictionary grouped together ABAP Workbench.For communication between abap and java & vice-versa gateway should be installed on your java system.

For jco connections refer this:

Differences we can spot in many for example read this

Applying kernel updates to a Java system is a little bit different. Unlike SPAM in ABAP, the counterpart for Java systems (JSPM) is able to apply kernel updates too. Although you can update the kernel of your system like in an ABAP system as discussed above, why not just use JSPM? In this way, you can combine the applications of the kernel update and Support Packages of standard Software Component in a single run.

Nonetheless, JSPM does not take over all manual activities. Since you can perform JSPM (which is a central tool) only on the central instance host as the <sid>adm user, JSPM is not able to restart the OS-level services of all instances situated on different hosts. For kernel update to take effect to all instances, the OS-level services of the instances have to be restarted. Therefore, you also have to logon to the hosts of the system cluster and restart the instances manually once JSPM has finished the kernel update on the central host.

It is fairly common to run a Java engine along with an ABAP engine in the same system. This type of system is called double-stack system. In the case that the ABAP engine works with a non-Unicode kernel, while the kernel of the Java engine is always Unicode, JSPM will apply both parts of kernel. It does not matter that the non-Unicode kernel actually belongs to the ABAP part. All that needs to be done is to put the non-Unicode kernel into the JSPM inbox.
