Dialog ABAP+Java instance fails to go to green (stays yellow)

ECC 6.0 SPS 13 (NW 17)
Win 2003
SQL 2005 (latest patch)
Using System Copy SR3
After performing a Hom system copy (from PRD) of my QAS system, the Java "component" of the dialog instance attached to the central instance fails to start. The central instance's java component loads just fine, but I get the following error in the jvm.bootstrap file of the DI.
Bootstrap MODE:

[Bootstrap module]> Problem occurred while performing synchronization.
Any thoughts on what I can do (without having to re-install the dialog instance) to fix this?

Hi,
I hope this helps you, my Basis team came up with the same problem. It is because of the JDBC driver that SR3 uses seems to be wrong. This is a slightly subtle problem and it took me a while to find.
- Open configtool
- Go to instance --> dispatcher --> Configuration Manager --> Local Properties --> rdbms.driverLocation
- Change it to C:\usr\sap\SMB\DVEBMGS00\exe\mssjdbc\sqljdbc.jar (or similar)
- Go to instance > server> Configuration Manager --> Local Properties --> rdbms.driverLocation
- Change it to C:\usr\sap\SMB\DVEBMGS00\exe\mssjdbc\sqljdbc.jar (or similar)
On my system it was set to C:\usr\sap\SMB\DVEBMGS00\exe\mssjdbc\base.jar;C:\usr\sap\SMB\DVEBMGS00\exe\mssjdbc\util.jar;C:\usr\sap\SMB\DVEBMGS00\exe\mssjdbc\sqlserver.jar;C:\usr\sap\SMB\DVEBMGS00\exe\mssjdbc\spy.jar which is the old school SQL Server driver.
Once you have changed these settings, save, exit configtool and restart the whole cluster. It will then start.

John

Hi
I am sure, it is logically incorrect, how you deploy byte code agent in abap only instance
Introscope Bytecode Agent runs on managed systems based on J2EE engines to report data to the Introscope Enterprise Manager, so it has to be setup only for Java Stacks.
Please check with the wily config guide again.
I am watching this thread for further view from others.

Kernel upgrade having ABAP+JAVA instance

Hi team,
Can you provide the procedure how to kernel upgrade for our windows system having ABAP+JAVA instance releae version 700.
Provide the links, your replies are very helpful.
Regards
Bhaskar

Hi Bhaskar,
You can use JSPM too in this case. Otherwise if you want to do it the old fashioned way:
> Stop SAP, Database, Saprouter, listeners and all the
related services.
> The location of the kernel is /usr/sap/<SID>/SYS/exe/run
> Take a backup of the files in this location and take a
print out of the ls -ltr (This is needed to give the new files the
correct permissions)
> Overwrite all the new files to the kernel location. The
purpose is to retain the old files for which the new version is not
available.
> The permissions of the file need to be changed as they
were before.
> Restart all the processes. The kernel upgrade is
now done. System
> status will give the newer version of the kernel.>
>
disp+work
Will give the
new Kernel version.

We wanted to install in the QA box , seperate instance of ABAP and JAVA for Nw2004s CRM using the same database via sapinst.
Any ideas of how to go about this ? Also has anyone faced major problems regarding system copy with sepetrate ABAP+JAVA instances setup for NW2004s .
Many Thanks .

CTS+ Configuration - Separate ABAP & Java Instance

Hello,
I have a pure ABAP ECC instance. I have a pure Java Internet Sales instance. I have NWDI.
I would like to centrally manage the Java transports from my ABAP system using CTS+. Is this scenario possible.
Integration of NWDI & CTS+.

Yes. the scenerio is very much possible.
Please refer to 3.1.3 for different ABAP and JAVA stacks in the following document http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/10456aac-44f7-2a10-1fbe-8b7bcd7bcd58?quicklink=index&overridelayout=true
And then you need to integrate NWDI with CTS+,

Changing message server port for ABAP+Java Instance

Hi,
We had change our message server port for the Java instance from 3607 to 3667.
We did this using the j2ee config tool. We also verified this information through the console config.
But when we look into system info URL using the URL as shown below, we still that the old message server port is being used. We have recycled the instance couple of times , but does not seem to help.
http://dfudsbw1.dfna.corp.dom:50700/sap/monitoring/SystemInfo
Any ideas where else we have to change the port no. for the message server

Hi guys,
I solved this on my own with documentation help from SAP.
I had to change the port no. in the Global dispatcher and Global server area as well.
Please see details from SAP below.
"Message Server: Changing Ports/Hosts shows which areas need to be adjusted if
the port or host of the message server changes. Ports are, of course, changed in the
instance profile of the Central Services instance. In the example, the port 3677 and
the HTTP port 8177 have been set, and the new host is called twdfxxx. You need to
use the Config Tool to set these values. For each instance, you need to maintain the
corresponding values for the Message server host and Message server port on the
Message Server and Bootstrap tab page. The connection details for dispatchers or
servers to the message server are maintained in the Cluster Manager. As shown in the
figure, the ms.host and ms.port are maintained, respectively, in the Cluster Manager
with Global Dispatcher and the Global Server. After you have maintained all of the
parameters, you can start the instances."

Hello All,
We are looking for Time out parameters for our ABAP and JAVA instances.
As users are complaining that they are getting time out error
while they are trying to access Cprojects from Portal.
I was able to check/collect the ABAP instance parameters from SMICM Tcode.

SAPINST: install IDES ECC6 EHP4 ABAP+JAVA (Windows 32 - Oracle)

Hi,
I have received the new IDES ECC6 EHP4 DVDs and I nedd to install a ABAP+JAVA instance.
It is not clear which option I have to choose in the SAPINST program.
In the past was present ERP2005 central instance. And now ?
Thank
Andrea

Hi Andrea,
As of SAP ERP 6.0 SR3, you must install an SAP ERP system only on 64-bit operating
systems.
For the dialog instance, you can still use a 32-bit operating system
As of SAP enhancement package 4 for SAP ERP 6.0, you can no longer install SAP
ERP dual stack (ABAP+Java) systems. If you want to use both SAP ERP ABAP and
Java Components in your system landscape, you have to proceed as follows:
1. Install a separate SAP ERP ABAP system.
2. Install a separate SAP ERP Java system.
3. Configure the connection of the SAP ERP Java system to the SAP ERP ABAP
back-end system
Hope this clarifies your concern!!!
Regards,
Rajesh

Procedure of System copy in Solman 4.0 through sapinst based on ABAP+JAVA

Hello Everyone,
Iam on solman 4.0 based on netweaver 2004s based on ABAP+JAVA instance and database oracle 10g and on windows 2003 platform.I want to perform system copy for solman 4.0 through sapinst and if someone can provide step wise step procedure with 10-20 lines for system copy with sapinst ,it shall be gr8 help.
I hv gone through the system copy guide on OSS also but its too long and confusing also ,a 12-20 steps procedure shall be useful and helpful . Also Iam performing system copy where source system and taget system are same ie; the current sytem where application is installed , i wanna copy tat only and perform system copy on tat server only.plz revert to tat also.
Requested to revert at earliest as this is very urgent. Points guaranteed.My Email id is [email protected]
Thanks and Reagrds,
Somya

I don´t think, that the system copy guide is confusing, it has basically a step-by-step procedure, depending on the "way" use use (a backup or R3load).
There are several ways of doing a system copy and depending on the one you want to use, the procedure is slightly different.

Starting J2EE(ABAP+Java Add In)

Hi
We've got BW 3.5 on Sap NetWeaver 2004 ABAP + Java (Java Add-In). We've got the problem with starting it.
Our system is on 1 server x64. We've got Windows 2003 Server. DataBase Oracle.
So in MMC everything is OK. We've got ABAP + Java instance (processes msg_server.exe, disp+work.exe,igswd.exe )
and Central Services (msg_server.exe, enserver.exe ).
First we didn't have some parametrs in our profile(DBW_DVEBMGS00_sap2). I added such as
icm/HTTP/j2ee_0 PREFIX=/, HOST=sap2, CONN=0-10, PORT=50000
rdisp/j2ee_start_lazy 1
rdisp/j2ee_timeout 600
rdisp/j2ee_start 1
exe/j2ee F:usrsapDBWDVEBMGS00j2eeos_libsjcontrol.exe
The problem is that i can't log in to my Visual Administrator and can't reach http://localhost:50000
Another problem is that i can't see in directory "F:\usr\sap\DBW\DVEBMGS00\work\" such log files as dev_bootstrap dev_jcontrol dev_server0 dev_jcmon
In SICF i've started all the services.
In the transaction SMICM i've got such a picture
HTTP Application Server Handler
ABAP Server operational = TRUE
J2EE Server configured = TRUE
J2EE HTTP port =
J2EE HTTPS port =
J2EE Server operational = FALSE
Default root access handler = ABAP
URL Prefix Table loaded = FALSE
What problem could it be? What log files should i see to find the problem?
From the first view only in dev_icm there are WARNINGS
[Thr 5876] *** WARNING => IcmNetCheck: NiAddrToHost(10.0.0.1) took 5 seconds [icxxtool.c 1012]

Thanks for you help

1) The folder is shared and the user <SAP_ID>adm(dbwadm) has all permissions(FullControll).
2) About J2EE profile parametrs i wrote before.
in my profile of ABAP + Java add in instance
(H:\usr\sap\DBW\SYS\profile\DBW_DVEBMGS00_sap2) i added parametrs

icm/server_port_0 PROT=HTTP,PORT=8100
I didn't manage to add parametrs because it's written "W:Unknown parameter jstartup/trimming_properties , a check cannot be performed "
[code]
jstartup/instance_properties
jstartup/trimming_properties

3)j2sdk1.4.2_11-x64 including jre
4) That's the problem.
When i run it and choose "Local Administrator menue" it's written "Can't open shared memory administration (rc=3)"
What problem could it be?

Problems in Dialog instance installation for ECC6.0(ABAP+JAVA)

Does anyone can help me what should be a procedure of installing Dialog instance for ECC 6.0 with both ABAP + Java Stacks.
When installing app server do we also choose ABAP and Java or just ABAP. Installation manual does not cover this and when we run the sapinst we have following problem:
The following are the activities that I have done as pre-reqs on the standby on the server that is to host dialog instance
I have mounted the following file systems on ddrsap02. Created the local filesystem /usr/sap/DSP/D00 and NFS mounted the others

Am I missing some pre-reqs or variable definitions?
I was going through the documentation and it says that /sapmnt/DSP/exe should be a local filesystem for a DI on a separate server. Will this create a problem ?
Also they talk about starting sapinst with the variable SAPINST_USE_HOSTNAME set to ddrsap02. I have tried this also
We are also not 100% sure about the settings for parameters:
rdisp/mssserv
rdisp/mssserv_internal

When we define it as per installation GUIDE (Abap+Java page 64) we get the popup message in SAPINST:

Other errors follow shortly.
Any help would be appreciated

Hi ,
are you able to resolve this error :Profile parameter rdisp/msserv_internal is not set for instance DVEBMGS01/DSP on host dprsap01.
You have to set the parameter in the default profile and restart the instance.
For further information refer to SAP Note 821875.</html>
? if yes , pls let me know , I am stuck with same issue while installing dialog instance .

Directory structure for ABAP+JAVA Dialog Instance

Hello,
Can any one clarify how will be the directory structure in a case where we have ABAP+Java System?
For Central Instance,DVEBMGS<instance no>
Central Services,SCS<instance no+1>
Ex:DVEBMGS20
SCS21
If I have another dialog instance,can I have only ABAP or only Java in that?What will be the directory structure?But I read that they will be in 1:1 ratio
Will it be D22(Only ABAP) or J22(Java only).
As a dialog instance,can ABAP exist with out JAVA.
or can JAVA exist without ABAP
Please explain the directory structure with an example.
Thanks,
Sudheer.

Kernel Change on ABAP+JAVA Dialog instances

Hi guys (& girls).
Another question from me.
I installed two Dialog instances for an ABAP+JAVA System (BI 7). The Central instance is on AIX, the DIs are running on SLES / x86_64.
Now i want to change the kernel.
It's fully automated for the Centeral Instance - i do it with the JSPM. Is there also an automated possibiltiy for changing the kernel on the DI? Or do i have to do it manually?
There is no extra JSPM on the DIs. How do you do that????
Thanks for your help,
Martin

The instances are linked against the current link, which points to the right kernel folder. I setup a script with copies my latest downloads to these folder structure by creating a new PLXXX folder. Then, when it is time, the "current" link is set to the new "PLXXX" folder. Thats all

Windows Central Instance ABAP+JAVA plus UNIX ABAP dialog instances ?

Hi everybody,
we are an SAP software partner and provide SAP complementary software on UNIX and Windows platforms.
Part of our software (a gateway) needs to be installed on the SAP application server.
In order to setup a cross-platform test environment for our developers, I was thinking about extending the existing SAP ERP 6.0 Windows-based Central Instance (IDES, Oracle, usage types ABAP+JAVA) by multiple ABAP dialog instances which run on different UNIX flavours (Solaris, AIX, Linux).
I searched the SAP Notes and found nothing which could confirm my plans, as this is quite an unusual setup and heterogenous systems are usually the other way round (CI on UNIX, DI on Windows).
SAP Note 1067221 however mentions that DIs on different OS platforms are only partly supported, but it seems this is only valid for JAVA DIs?
As I need only ABAP DIs, I hope my plans are fine?
Many thanks for your feedback
Markus

Well - what is "usual" depends on the requirements
It's possible to do that. Technically there's no difference whether an application server is Unix or Windows based.
There are, however, a few things to take care of:
- if your system is non-Unicode, sorting algorithms are different on different platforms. Unicode systems use ICU which is cross-platform
- if you want to automatically distribute your kernel on system start you will need to create a "share" on the Windows machine and make it accessible from the various other platforms. You can, however, ensure "manually", that you use the same kernel patchlevels on all systems, then this is not needed
- Windows is LittleEndian whereas most Unix systems are BigEndian, depending on if you exchange data between those systems (means, binary data, files through NFS) the programs must be aware of the fact, that a file can be either LE or BE.

Can we access WebShop on Dialog Java Instance?

Hello
I had already installed ABAP+Java system on the system and already configured the WebShop completely. However I have a problem that system only access from user internal zone but I want Customer to access Webshop themself by URL. Can I install only Java Dialog instance in external zone in order to allow Customer to access Webshop by this server? If not, do you have any idea for this?
Thanks,
Beaw

Hi
I had already solved the problem, weI only setup SAP Web Dispatcher to be a gateway.
Have a nice day
