Upgrade Single JAVA Component Patch Level Using SUM Tool

[SumitPatel11]

Hi Friends,

I came across few posts/threads where people are looking -How to apply patch for single component with out generating XML file in solution manager. So I thought lets write a blog on this topic.

In this blog I would like to share detailed procedure - How to upgrade single JAVA component patch level using SUM tool without generating XML file, for example here I have updated the component ENGINEAPI from patch level 12 to 16.

Download the patch from SAP market Place and place it in a folder as per your convenience .

->Make sure we have component ENGINEAPI patch 16 available on the server

Here in this blog  I have used the SUM tool SP level 20

Extract and Give Permission To SUM Tool

After extracting the SUM TOOL SAR File

GIVE the PERMISSION and OWNERSHIP to SUM Folder

We have to change the ownership of SUM Folder from root to <sidadm>

Use following Command:

chown <SID>adm:sapsys -r <SUM>

Extract the SUM tool with <sidadm> as shown below



Give Full permission to folder SUM

> chmod -R 777 SUM

In order to start the SUM tool in Linux, we need to run below command (it will restart SAP Host Agent)

Login with root user and execute the below command it will configure the host agent

<Path Of SUM Folder>/SUMSTART confighostagent <SID>



For java stack we have different URL for SUM tool

http://<hostname>:1128/lmsl/sumjava/<SID>/index.html

If you have extracted SUM tool with <sidadm> then we have to login with <sidadm> user itself, otherwise it will not allow to login with root user.



Click Next

 



Provide username <sidadm> and password

Click Next

 



Select option ->Manually Prepared Directory because here we are just updating patch of single component , provide the path of the patch file

Click Next

 



Download the file from URL https://tcs.mysap.com/crl/crlbag.p7s

Place it in particular path and provide the path of the file crlbag.p7s

Click Next

 



Provide Administrator user credentials and click Next

 

Here we are updating patch level of component  ENGINEAPI from 12 to 16



Click Next

 



Apply the maintenance certificate license and click next

 



Click Next ,it will begin the downtime of the system, make sure you have proper maintenance downtime window of atleast 30 mins.

 





It is starting the java application





 

We also have other option to deploy java patches using Telnet but it is always good a practice  to follow SAP Standard tools for standard procedures.
