How to Start Serv0 Process in ABAP+JAVA Stack without restaring

Hi
We have our SAP Systems in ABAPJAVA Stacks. Some times the server0 process does not show up at the AS/400 screen screen even though all other processes showup. Is there a way we can start Serv0 Process in ABAPJAVA Stack without restaring the entire system.
I tried the following. Loged in to the ABAP System and from transaction : SMICM
Menu Option
Administrator --> J2EE Instance(Local) --> Restart --> Yes
Administrator --> J2EE Cluster (Global) --> Restart --> Yes
but still the service did not show up.
Any Help in this reagrd would be greatly appreciated.
The following services are shown in the green screen at the AS/400 OS Level
   Subsystem/Job                 User        Type CPU % Function        Status

Hi Kishore,
first of all, there's probably a problem with server0. Generally it should come up automatically. And one can see JCONTROL and DISPATCHER, so there must be some problem with SERVER0. This could be a timeout for instance. One has to check dev_server0 and std_server0 files.
However, you can of course start/stop the Java part independently from ABAP using the transaction SMICM. That's the official way. You should be able to use "soft shutdown with restart" if you just want to restart the Java stack. If you have doubts that this process went fine, trigger a "soft shutdown without restart" and wait until all java processes are gone (JCONTROL, DISPATCHER, SERVER<number>'s and SDM). Then use "Restart Yes" to trigger a new start.
But, as I said, there's probably some issue in server0...
Best regards,
Christoph

How to create Roles in UME (ABAP+JAVA stack)

Hi,
I have created roles earlier on JAVA stack alone. However, this time I am working on JAVA+ABAP stack. When I am trying to create role in UME, I am getting only two tabs:
General Information
Assigned Groups
I am not getting Assinged Actions tab here.How do I assing actions ?
Can any one please help me in creating roles in ABAP+JAVA stack.
That would be a great help!
Regards
Faisal

HI Faisal,
When ABAP is the UME, you can only edit users / groups that are J2EE only. Any group that is defined in ABAP is read-only for the Java Server to prevent conflicts (there is no synchronization) and has to be changed in ABAP.
Please take a look at this link, which has a great graphic describing this.
http://help.sap.com/saphelp_nw04s/helpdata/en/7c/36dcd59865b246b993c471199ba37a/content.htm
So, if the Java group was created in ABAP, the ABAP user has to have the ABAP role assigned to him, so that he is in the group on the Java server. make sense? The graphic in the link above really explains it well I think.
If you a new / custom Java group (not in ABAP) then you should be able to assign users to it from the Java server.

Hi,
Please provide the full log entries of server0_out.log.
You can access UME service properties in config tool by following this path..
Global server configuration -> services -> com.sap.security.core.ume.service
There you can set the following settings for new client 900 (it u want to change it)
ume.r3.connection.master.client
ume.r3.connection.master.user
ume.r3.connection.master.passwd
Refer this [useful link|http://help.sap.com/saphelp_nw04s/helpdata/en/45/1bbdccc7850064e10000000a1553f7/frameset.htm] to get more detailed information.

Also, Make sure that the Users J2EE_GUEST, J2EE_ADMIN, SAPJSF ABAP Users exist in the ABAP client (i.e. client number as mentioned in ume.r3.connection.master.client ) and they are not locked. All the required roles need to be assigned properly.

How to start a process

The process can be started from gobal creation activity in BPM 10g. I create an ADF or Java client application which can show the information of processes.
How to start a process from java? For example, a user can click a button and then, one or more processes can be started.
createProcessInstance in ADF is striked.
Thanks a lot.

Yes, I use PAPI in ADF and check the document in the web. But the code likes following is striked by jdeveloper 10g.
session.createProcessInstance(processId, arguments)
What I want to know is the code snippet which replaces "session.createProcessInstance(processId, arguments)"
Then, the user can start new instance from an ADF application (with PAPI code).

ABAP+JAVA STACK STARTING ISSUE a Work Around

Dear Users,
I recently got an issue in duel stack where in Java stack was not coming up. According to the Trace file i was about to follow the SAP Note: 940893. But everything was fine for me. Then i tried a work around. I started Java first and then after sometime ABAP. It worked for me. Might be useful for others as a work around. If useful make know. If i am wrong again let me know.

Hi Manjesh,
Then i tried a work around. I started Java first and then after sometime ABAP. It worked for me.
It looks like Server has insufficient memory to hold ABAP+ JAVA stack.
You can think of the following
1) Reduce the no of WPs in ABAP stack
2) Reduce the JAVA memory settings to half using configtool
3) Restart both ABAP and JAVA
4) Check the results.
Hope this helps.

How to start the process.

I'm using CE 7.3 for BPM.
I would like to start process from simple menu not using Process Repository.
Does anyone know hot to start BPM process form menu ?
Do I have to develop webDynro applicatin that calls web-services for staring the process ?
Best regards,
Koji Nagai

Thank you for your reply.
I understand how to start BPM process by using BPM API.
But in my project, we need to minimize the developed objects.
To use BPM API means to develope programs right ?
If possible, I would to start BPM process without developing programs.
Is there any way to start BPM process from menu without add-on programs.
Best regards,

As an aside, I will attempt to get rid of the READY deployment and deployment unit using deactive_deployment.sql
Now, if I attempt to use deactivate_execution.sql on any of the executions with status BUSY I get:

ORA-06512: at line 4
owner_owr@ORKDEV01>
So all the seems to remain is to use abort_exec_request.sql
This does the job, but the script itself hangs.
I think it has to do with the l_stream_id not being checked again after the initial IF. I think it should probably be part of the loop condition as it is again reset in the do_acks inside the loop.

Syncronization of ABAP+java stack during the upgrade.

Hi All,
We have successfully upgraded our BWD & BWQ which is ABAP+JAVA stack .
we have followed the process of uninstalling the java stack and removing the j2ee and SDM folder and starting the system for the upgrade.
Tomorrow we are going to start BWP , i found the way to syncronize the upgrade in upgrade manual like starting the SAPjup when upgrade asks for syncronization.
Can any one suggest me the process of starting the SAPjup for sync like already upgrade is running with SAPup and just waiting for SAPjup to sync it's just a norwal way of starting the SAPjup ? or anything.
But i am thinking to go in normal what we followed for the BWD&BWQ.
Please suggest...
Thanks,
Subhash.G

PLease proceed with your old strategy it sounds better.

We have requirement for SAP BW 7.4 on HANA ABAP & JAVA stack integration.
Please clarify the doubts.
1. Is there any possibility to install ABAP & JAVA stack same SID?
2. If install different with SIDs, How can we do integration? Any restriction is there to integrate?
3. Can we use same HDB SID for both ABAP & JAVA stack?
4.We plan to configure the JAVA stack as UME data source from ABAP stack, Is it good practice?
Any one share the better ideas & solutions for this issue.

System Copy from ABAP Stack to ABAP+Java Stack

Hi,
Is it possible to system copy (homogeneous or heterogeneous) from a system based on ABAP Stack to a system based on ABAP+Java Stack? Is it the normal system copy procedure or something aditional is required to do. Pl. advise. Thanks
regards
Edited by: Abdus Samad on Oct 24, 2008 8:13 AM

It depends on what you want to copy, a system copy will always wipe out the existing target. But if you want to only copy data, you might be able to do a client copy. You can start with this SAP note: [552711 - FAQ: Client copy|https://service.sap.com/sap/bc/bsp/spn/sapnotes/index2.htm?numm=552711]

ABAP / Java stack refresh

Does anyone have documentation on how to do a refresh for an ABAP / Java system? I've done a system copy to create a new system with SAVLIB/RSTLIB by:
Export the SDM
Saved ABAP Database
Saved Java Database
Run the system copy with RSTLIB option on the target system, but when I did this, the system didn't already exist on the target side.
But if I have a development system (say abc) and want to refresh it with production (xyz), how would I do this with the addition of a java stack?
We have documentation and have done this plenty with just an ABAP stack, but not so with an ABAP/JAVA stack.
I would think if I tried to use the system copy method mentioned above it would error because the target system (abc) already exists.
Can anyone clarify for me? Thank you.
~TJ

Hi TJ.
Looks like your question is not specific for SAP on System i. Most likely you get more answers when you ask it in an platform independent forum. I would suggest the SAP NetWeaver Application Server forum.
But I think it would be very interesting for many of us here in this forum to let us know if there is a easy way to accomplish the refresh.
Best regrads,

Abap+ java stack or Abap stack

Hi All,
How to know whether a system is ABAP+ JAVA stack or JAVA stack.
In our system EP6.0 which is JAVA stack holds JC00 which is a java instance direcory. In BW system we have SCS20 and Dvebg...00 directories is it ABAP+ JAVA stack or ABAP stack with J2ee engine services.
Please suggest me...
Thanks,
Subhash.G

In the forder structuer usr\sap\<SID> if you have DVEBMGS<XX> then it's ABAP and if it's JC<XX>, then it's JAVA. Also if under DVEBMGS<XX> you have j2ee and SDM folder then it's a dual stack that is both ABAP and JAVA.
As for the URL if it's a dual stack then using the browser use the user j2ee_admin and the specified password, else if it is only java then use administrator user and the specified password.
If it's a dual stack you can also login using sapgui.
If in case its single stack AS_ABAP
THere will one be a single node i.e. no message server and enque server. The folder stur would be /usr./sap/<SID>/ and tou would find
DVEBMG SYS folders only.
IF in case its single stack Java server then
In mmc. you will find, 2 nodes one for message server, enque server and the other for the SDM, dispatcher and server0
the foder struct would be
/usr/sap/<SID?
JC><CIno> SCS<no>
Now in case if you have double stack i.e. AS-java and AS-ABAP you would will find these things in mmc
Message server and enque server
disp+work, message server and wp
the folder struct would be
/usr/sap/<SID>/
DVEBMG<no> SCS<no>
