In every Kernel Patches, either sap changes some parameter or adds/remove a parameter. If we are planning to add a new parameter we have to first verify if the parameter is supported by KERNEL or not. OR we can check by going through its particular note.

To do this follow below step to check if the parameter is included in the KERNEL or not

sappfpar all          # will give list of all parameters

You can grep to check the parameter is supported in your KERNEL or not.

IDEALLY we should run sappfpar check after doing parameter changes, especially memory related parameters, but for planning for adding of new parameters we can use this step.

First open the start page by referring to http://ipraby.com/sap/how-to-open-startpage-of-sap-java

once it is open click on System Information

Or use link – http://<hostname>:5<NN>00/nwa/sysinfo
NN = SAP JAVA Instance Number

Then Goto, Component Info Tab,

In the Development Components, select “All Display Components” in Display Drop Down Combo Box.

Apply Filter in name section, and check what is the SPS level of the SAP JAVA AS Component.

You can open startPage of SAP JAVA system by providing the correct HTTP or HTTPS port.

Please refer http://ipraby.com/sap/sap-java-ports for more details on JAVA ports.

In SAP AS JAVA 7.0X by default index.html was used.

• HTTP Link – http://<hostname>:5<NN>00/index.html
• HTTPS Link – https://<hostname>:5<NN>01/index.html

In SAP AS JAVA 7.1X onwards by default startPage was getting used.

• HTTP Link – http://<hostname>:5<NN>00/startPage
• HTTPS Link – https://<hostname>:5<NN>01/startPage

Where NN = Instance number of SAP JAVA AS

if connecting to SAP AS via HTTP port use rule 5<NN>00
else if connecting from SAP SCS/ASCS via HTTP port use rule 5<NN>13
in later case, sapctrl<NN> must be defined in /etc/services file.

If connecting directly to SAP AS via HTTPS port over SSL use rule 5<NN>01
else if connecting from SAP SCS/ASCS via HTTPS port over SSL use rule 5<NN>14
in later case, sapctrls<NN> must be defined in /etc/services file.

for connecting through any AS use below for java systems.

Port	Rule
IIOP initial context	5<NN>02
IIOP over SSL	5<NN>03
P4	5<NN>04
P4 over HTTP tunneling	5<NN>05
P4 over SSL	5<NN>06
IIOP	5<NN>07
Telnet	5<NN>08
JMS	5<NN>10

<NN> = 00, 01, 02, 03, 04, 05, …….. 99
