Solution Manager 7.2 – Upgrade – III – Dual Stack Split

Hello Friends,

Now we have SAP Solution Manager 7.2 with Support Pack Stack 01 system upgraded and now its tile to split Dual Stack System before we start using it. Split of ABAP and JAVA stacks is just an effect of the Netweaver release strategy.

Reference : 1797362 – Dual-Stack Split for Systems Based on SAP NetWeaver

In order to split system, we need to use Dual Stack Split tool (SWPM*.SAR)

SAP recommend that you download the latest tool support package and patch level when starting a new provisioning project at: http://help.sap.com/sltoolset -> System Provisioning -> Download Software Provisioning Manager

In my case I am going to execute as below because SAP is recommended to KEEP DB. Moving database is also supported by SAP

For more Information on Dual Stack Split please go through : http://scn.sap.com/docs/DOC-25162

DUAL STACK SPLIT PROCESS

Note: Please use this process if you have Central or distributed installation of SAP Solution Manager system

Export Source System

STOP JAVA System

As Result

Depend on your option select one. In my case as below

Confirm Disable AS Java

Take over ICM port (Mostly all 50XXX Ports)

SCS Instance Profile parameter

Note: Restart you Solution manager system after export finish

Install Target JAVA System

Select Option

Select New SID name for Solution Manager JAVA

Provide kernel: 51049724_10

Java Message Server Port (IN MY CASE ACCORDING INSTANCE NUMBER)

Adept DB for Target system

Select option as below

Select profile of your new JAVA System

Select existing solution Manager Database

Make sure you have follow note

Replace old DB id with New DB ID in Database

When you open config tool you will get message below

Change user and password and SAVE settings

Note: Whenyou re-open tool you will able to connect database without any error

Install Primary Application Server for JAVA Stack

Select as below

Profile of your new System

Select existing solution Manager Database

Provide JAVA DVD : 51050526

Select NO SLD (For now and we will configur it later )

Reuse ports

Prompt for restart

Remove JAVA Stack Primary Application Server

Note: If you have Additional JAVA Application server please remove it first

Select as below

Select profile of your first solution Manager profile (Dual Stack)

Remove SCS instance from Dual Stack System

Select option as below

Select profile of your first solution Manager profile (Dual Stack)

Now your system is Single Stack only 🙂

Hope this document show you guideline to split your Solution Manager Dual Stack system. Don’t forget to read my next document on post configuration after dual stack split

Thank you for reading and comments are welcome.

For the Export Source System steps, did you intend for the checkbox to be set "checked" on in the screen shot for Enable reuse of SCS ports during target system installation? or should that checkbox be left unchecked?

You can decide what option you want. I like to reuse ports thats why I have it selected.

As per SNOTE 2227300 – Further Upgrade Information for SAP Solution Manager 7.2

IMPORTANT: When you run the “Same host” option, make sure to select the “Enable reuse of SCS ports during target system installation” option within Step 2 / Define Parameters / SCS Instance Ports Reuse.
The split tool will otherwise adjust the Java SCS port numbers, as the Java SCS instance number changes. And you need to install a SAP Web Dispatcher, as proposed below, to reconnect existing Diagnostics Agents.

hi yogesh..you have kept the checkbox unchecked but i have adviced to keep it checked...this is for Enable reuse of SCS ports

i have selected the checkbox since i am using the same host for my java instance installation

Hi Yogesh

When you split the ABAP stack and Java Stack.

Can you install the Java Instance on the same Server where the ABAP stack resides ?

or do you need to install on a different hardware or Server ?

Can we intsall a secondary database for the Java instance on the same Database Server ?

Thanks

Hello Mohammed,

Please find answers below...

Question 1:

Can you install the Java Instance on the same Server where the ABAP stack resides ?

or do you need to install on a different hardware or Server ?

Answer 1:

You can install on same server or on different server its all up to your choice.

Question 2:

Can we install a secondary database for the Java instance on the same Database Server ?

Answer 2:

Technically yes but what is the benefits of doing it? I recommend you that use the same database instance and create new database for java system.

Please let me know if you have any other question.

Regards,

Yogesh

Hi Yogesh,

We have selected Enable reuse of SCS while export. During SCS installation again selected reuse of SCS instance and continued with SCS installation. But as that same SCS instance processes are running on the same host from it’s dual stack system, it took different instance number for SCS installation.

Also when I checked the /sapmnt/<SID>/profile/<SID>_SCS##_host it has entry like

# Reuse <SID>_SCS**_hostname
#———————————————————————–
ms/server_port_0 = PROT=HTTP,PORT=81##

Please let me know how it normally works. And what this entry in SCS instance profile means.

** is old SCS instance number

THanks,

Urvi

Hi Yogesh,

I am basis only, so not asking for theoretical part. Let me re-frame my question here.

We want to have keep database, and reuse SCS instance number. So far we performed export java step and we checked the check box for reuse SCS as per your blog.

Now 2nd step is install scs instance, if got completed successfully. However when checked it has created SCS with 00 whereas we want it to reuse 05 (we had checked SCS reuse option already). But as SCS05 is still part of dual stack running on same host it has not reused it. Conceptually that is fine. So now whether my SCS will not be able to use 05 anytime even if I had given input reuse option for it. My requirement is to reuse SCS.

Thanks,

Urvi

When you split how it can be a part of dual stack?

When you reuse it will be part of java/abap single stack.

Hi Yogesh

We have below scenario:

Primary Application server and AAS on Linux

oracle DB, ASCS, SCS, ERS are on AIX HA scenario: Could you please let me know which option we are going to proceed, I have raised the OSS message to SAP, but different people had given different suggestions.

1st One: Move DB option

2nd one: First migrate Central services ASCS, SCS to LINUX and Proceed to DSS. (Even I have read the DSS guide which was mentioned DSS not supporting HETROGENIOS system configuration.

Could you please suggest your opinion, If 2nd option is correct how to proceed ( Are we need to Install new ASCS & SCS on LINUX and make the OUR environment homogeneous ?) After splitting, are we need to again install ASCS SCS, ERS on AIX? because we are using HACAMP HA solution.

Your advanced suggestion is most appreciated.

Hi Yogesh,

I guess you might help me in my issue.

We have dual stack solution manager Distributed environment with PAS is running on Linux x86_64 and DB is running on AIX and SCS&ASCS is running on a different Linux server.

basically DB is on AIX and PAS/ CI is on individual Linux servers respectively.

Now we have upgraded the Solman to 7.2 and currently we are doing the Java split we did the step-1 and took the export of upgraded PAS(running on Linux) of dual stack and it created the below export structure

drwxrwxr-x 2 md1adm sapsys 4096 Jul 21 21:30 SEC
drwxrwxr-x 2 md1adm sapsys 4096 Jul 21 21:30 TOOLS

drwxrwxrwx 6 md1adm sapsys 4096 Jul 25 09:44 solmanexport_15

now using this migration export we are running Step-3" Adapt database for Java target System " and it ends in error and error shows as below

now if i refer the file error log /usr/sap/sapinst_instdir/DSS/KeepDB/ORA/AdaptDB/getDBUserSource.log it says as below

sh: /usr/sap/sapinst_instdir/DSS/KeepDB/ORA/AdaptDB/sapjvm/sapjvm_6/bin/java: cannot execute

Here is the main issue --> when i proceed further, SWPM is extracting the sapjvm6 folder from the PAS export from step-1 which i gave as input initially in ADAPT DB procedure and this export i took in Linux server and it got created using the SAP Kernel of Linux server as per below.

below is the sapinst.log from Linux PAS while taking export for step-1

Output of /usr/sap/MD1/sapinst_exe.57595.1500654313/SAPCAR -c -v -i -C /usr/sap/MD1/SYS/exe/jvm/linuxx86_64/sapjvm_6.1.102 -p 0755 -f /usr/sap/MD1/SOLMAN_EXPORT_720/EXE

a sapjvm_6/include/linux
a sapjvm_6/include/linux/jni_md.h
a sapjvm_6/include/linux/jawt_m

Note :- SWPM in step-3 on AIX is extracting the sapjvm from PAS export and running the current step where we are getting this error.

I believe this is the reason why java can't be executed because this java utility was built while taking export in Linux using SAP Linux kernel and giving this as input to Adapt DB on AIX which is incompatible and hence it doesn't execute.

Replace old DB id with New DB ID in Database

- When you open config tool you will get message below

- Change user and password and SAVE settings

Note: Whenyou re-open tool you will able to connect database without any error

but currently i am not in removal of JAVA step.

I am running Step-3 "ADAPT DB for JAVA", the solution you suggested could be useful at later stage.

any suggestion in current scenario ?

downloaded sapjvm6.SAR for AIX and replaced the Linux export under ./EXE/DBINP/sapjvm6.SAR with the downloaded one for AIX and re-triggered the ADAPT DB and it worked fine.

Hi Yogesh,

I have upgraded Solman 7.1 sps12 to solman 7.2 sps5 and currently performing dual stack split. I am currently at the step install instance bas scs00 during scs instance phase where the install is ending with an error .

We are trying to install the SCS instance on the same server where we have original system.

Appreciate your help.

Hi Yogesh,

If, as a Solution Manager and BASIS consultant, I had access only to ABAP stack (after the dual stack split), will I be able to perform configuration of all Solution Manager 7.2 functionalities? Would it cause any kind of restriction on my being able to monitor Solution Manager itself or perform any maintenance activities like CIM/CR upgrades?

Hello Experts

I have successfully done the dual stack split and Solution manager is running perfectly fine with both ABAP and Java running on same server. Scs got removed from the original dual stack solman and added to Java node.

But now the problem is there is no SCS running under Abap node and When i run the SUM tool for applying new support packs it says no :

Severe error(s) occurred in phase PREP_PRE_CHECK/INSTANCELIST_INIT!

Last error code set:
SYSTEM MANAGER: instance list does not contain SUM central instance.

Whereas everything is there but SUM tool is not happy anymore.

Below is the instance list running on the same server but because its different instance number now for ABAP and JAVA.
