So you developed and application on your own and you don't know how it's "linked"? No offense, I'm just trying to understand what you want to know.

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
/dev/appsaph 5505024 5503856 1% 5 1% /usr/sap/DSP/D00 (is this required or SAPINST should create it itself)
ddrsap00:/stage 419430400 149761708 65% 90835 1% /stage

ddrsap12:/usr/sap/trans 2752512 1084932 61% 5107 3% /usr/sap/trans
Then when I run the sapinst from ddrsap02 to install the DI I get the following error

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
Accorss Devault Instance and Services Instance profile.
When we define it as per installation GUIDE (Abap+Java page 64) we get the popup message in SAPINST:
<html>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>
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.

In ABAP+Java system installation

Hi,
I installed ABAP+Java system On that i installed XI 3.0 SR1.I after applying the J2EERTOS11_0-20000118.SAR patch on J2EE engine.This patch consist of lot of bugs.I just stopped the installation of patch.After again when i log on to J2EE engine with port 50000.Its showing no page dispaly on localhost.I checked the J2EE instance.J2EE instance running properly.Even i can't log in to SDM and J2EE administartor.
Before patching I can able to log in.But now its loging failing.
May be the error is at 50000 port.I installed everything on one Central instance.
Need urgent reply.

Hello,
i think that you want to patch your j2ee-server. Therefore you have to download four parts for PATCH SP11.
Support Packages and Patches > SAP NetWeaver > SAP NETWEAVER SAP NETWEAVER 04 > Java Server:
J2EERT11_0-10001982.SAR (Part 4/4)
SAPINST10_0-20000118.SAR
J2EERTOS11_0-20000118.SAR
CTRL<database>11_0-20000118.sar
You have to download all these files and extract then in one folder - there you have to use the sapinst and install the patch.
I hope i understood your requirement the right way.

Andr'e

SSO within an ABAP+JAVA on the same host

Experts:
We have a dual stack (ABAP+JAVA) NW04s on the same host.
The usage type EP7 is enabled.
From this EP7 we want to access its own ITS thru SSO.
We configured the SSO just like we did for the EP7 + ECC on 2 different hosts.
However, we are always asked for an ID/password when trying to test the SSO from the EP7.
The error is:
"SSO logon not possible; browser logon ticket cannot be accepted"
Please advise. Points guaranteed. Thanks!

hi,
I also tried to do the same, but i think it's not possible.
I read somewhere that SAP recommends to use different instances of ABAP and Java. I installed seperate ABAP and Java instances on the same host and then configured SSO using the Configuration Wizard in NWA configuration. and it works perfectly.

Ankur

SSO To J2EE engine of ABAP+JAVA Addin Install

Hi all,
I have setup an SAP system as a ABAPJAVA Addin Install. The system is running NW04s SP11. I have an SAP Portal installed on the JAVA side to support some BW functions. I would like to do SSO from the users desktop directly to the portal component. Is this possible with this type of install? I have setup Kerberos / SPNego with a JAVA only install connected to a Microsoft ADS. I have also configured the system to use MYSAPSSO2 tickets from another SAP system, but that requires the users to go to the other SAP system before going to ABAPJAVA Addin system. I would like the users to go directly to the ABAP+JAVA Addin system via a URL like http://server:port/irj/... and get single signed on to the system. Is this possible?
Any help is appreciated!
Russ Scherbarth

Hello Russ,
yes it is possible to configure SSO using SPNego Loginmodule (Kerberos) for this type of system as well. You also can use the SPNego configuration wizard to get the configuration work done, but you need to perform some manual follow up work as well.
So my recommendation is check the online documentation for wizard based configuration AND manual configuration, perform the wizard based configuration (more or less the same as you did for the other system) and afterwards (depending on your JDK) you might have to perform some manual follow up activities.
Select as user resolution mode prefixbased, the attribute to be used is uniquename. In addition you need to create the service user in the portal database (when using SUN JDK), as you do not have direct connection to Active Directory.
With best regards,
René

DB refresh on Netweaver 7.0 ABAP+JAVA system - Issue

Dear Folks
I am having an issue with starting the Java instance after system copy.
This is the situation
System QAS database was refreshed from system PRD.
Both the systems are on NW 7.0 Ehp1 SP 18, in a HPUX/ORACLE environment.
Our normal landscape is full of R3 systems so teh DBA's have been historically doing DB refresh by copying for teh Oracle fileystems and then renaming the schema and some post db refresh activities to get the DB in teh target system up and running. Pardon my terminologies I ma not a DBA. The abpove procedure has worked fine with R3 systems.
But with the above mentioned Netweaver system ABAP instance is running fine after refresh while Java instance is not since SMSICM-> Goto-> HTTP Server -> DIsplay Data is showing
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        = TRUE
There are no other dumps or errors in the system and teh startup logs do not show any error. I have looked up online and the System Copy Guide for 7.0 systems and I understand SAP recommends using sapinst. But I would like to know if there is a workaround to fix the j2ee instance.
I have seen a few forumns where people have had similar issues but no solution.
FYI, The the Instance_IDXXXXX in the SAP J2EE Engine- Config Tool in system QAS is that of PRD and there is no entry for the instance ID of the QAS system.
I have tried changing all the entries that are pointing to PRD under Cluster_Data-> Instance.properties.IDXXXX to that of QAS and saved and restarted but no luck as the Instance_IDXXXXX of QAS does not show up in teh config Tool menu.
All the properties files at teh OS level are pointing correctly to QAS, so I would liek to know if there is any way to change the config on eth DB level.
Thanks in advance.
sapkid

Hi,
When you go for ABAP+JAVA system refresh please always ose the JAVA export method .
Take the JAVA export of the source system with the help of sapinst.Check the j2ee_admin and the ddic password of source system.
then you need to get the offline backup of the Source system.
then import it on the target system wth the help of sapinst and in the middle it shall promt you to restore from the backup of the source system.
Always use this method as JAVA stores it file at file system level and in the database.So you need both the files .
Thanks Rishi Abrol

NWBC 2.0 logon failure to ABAP/JAVA stack system

Hi,
Maybe not the correct forum, but there isn't any for the NWBC.
I am testing the Netweaver business client 2.0. It seems to work fine for portal connections, but when i try to connect to a netweaver system (abap+java) using the internal ITS url (http://host:8000/sap/bc/gui/sap/its/webgui), i get an error saying:
Could not open the logon window on server <host> (server URL http:// <host>:8000/sap/bc/gui/sap/its/webgui, logon URL http://<host>:8000/ticketissuer/TicketIssuer?NWBC_avoidCache=460486210'); check if the URL is valid and the server is running
The URL works fine on the NWBC 1.0. Is there something significantly changed in 2.0? Does the 2.0 version only accept portal URLs? I can't find any documentation on this.
regards,
Bas

hi,
There might be problem in Properties in the Connection Sections
Also see the below documentation as i dont know what parameters you might have given for configuring.

SAP BW 7.4 on HANA ABAP & JAVA stack

Hello,
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.
Regards,
V Srinivasan

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.

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]
