Stack JAVA as Add-in installation

Hello
This is my first time on forum.
We are installing a Java Add-in on our Development System
Abap only.The response of prerequisite checker is the necessity
to install Manteinance Level 5 and our Aix 5.3 is on ML 4 at OS level.
<i>Prerequisite Checker finds one Condition
with Severity High not met:
"For AIX 5.3 at least maintenance level 5 is required.
Current maintenance level: 4. (Updated 2006-10-06)".</i>
Speaking with our Sistemistic team they refer on some impacts of this
ML.
Therefore the question is if install or not this ML 5 for stack Java?
Thanks in advance for any suggestion.

Hi Paolo,
You can give it a shot but, even if it goes well, be aware that SAP may refuse to support your Java in case you need them to look at some issues.
Regards,
Mike

Web AS-Java 640 Add-In installation for XI

HI Guys,
We have installed Web-As ABAP 640 on Windows 2003 and MSSQL 2000 SP3 server.
We have created named instance called "SAPDEV01\SAPXI".
While installing Web As-Java 640 as a Add-In we have encounted following error:
"SEVERE: couldn't connect to DB
java.sql.SQLException: [DataDirect][SQLServer JDBC Driver][SQLServer]Login failed for user 'SAPGXDDB'. Reason: Not associated with a trusted SQL Server connection.
We have checked the authentication mode of MSSQL server, it is "SQL server and Windows", still we are facing the problem.
Please give us solution ASAP.

Specific Requirements
Take the following specific requirements of the new installation process into consideration:
- The previous SAPInst installation service Java Add-In in SAP ERP 6.0/SAP NetWeaver
7.0 was able to add Java usage types such as EPC, or EP, to existing ABAP-only
systems. This was possible only, if you added AS Java at the same time. The option of a
Java Add-In installation is not any longer available as of the enhancement package 4 for
SAP ERP 6.0. Thus, it is not any longer possible, for example, to add EPC and EP
together with AS Java to an ABAP-only system.

Failed on Java CI add-in installation with Java Admin Account Create

I've installed an ABAP stack and it works smoothly. Java Central Instance Service(add-in) and Java Database Instance(add-in) are both installed successfully. When I install Java Central Instance(Add-in), I get an error when system asks me to input passwords of Java admin accounts. I use same password for all sap account, eg. james123, but in this step, I input same password, the screen does not change to the next.
I paste error info below for reference.

Hi
I still got the problem.
Here is some more details
1. "Central Instance Java Add-in" installation.
2. The step is "ABAP UME" (Enter the J2EE engine user passwords). System ask user to enter password of administrator user, password of communication user, and password for SDM.
I enter a password like james123, it does not go to next screen. then I try to input other passwords, it does not go to next screen either. Does password cause the problem? What's the rule of password? And what's the return code 2 in below log file?
Here is the information which I can find out in file sapinst_dev.log.

Separating ABAP and J2EE stack after an Add-in installation

Hi All,
While I need to migrate an Add-in installation (ABAP + J2EE) to a new machine, there is also a requirement to separate these stacks into two separate instances. Can you please suggest the approach for this? Any suggestions are greatly appreciated.
Regards.

Hi Vincent,
if you want to have a two stack system you better install it that way, meaning two different installation for both.
Unfortunately then you might have some trouble with security after this I cannot foresee.

Benny

Error during Java WS add in installation

Hello,
I am receiving the following error when trying to install the Java WS 6.4 add - in to an existing ab-ap installation. We are using SQL Server 2000 on Windows Server 2003 and doing an ABAP / J2EE unicode installation. It looks like a database table it is looking for is missing. I looked in the SAP tables in the database and the table is indeed missing. Does anyone know if I've overlooked an installation step that would resolve this issue for me?

BI 7.0 Java Add-on installation hangs

Hi Guru's
While doing upgrade of BW 3.5 (Netweaver 2004) to BI 7.0 (Netweaver 2004s) during Java Add-on installation at "Database Instance Java Add-in" phase the installation hang on "Import Java dump" phase.
I have tried to kill and restart the installation 2-3 times and restarting the complete installation once again it stops at the same phase. Kindly let me know what can be the reason because we have not face this issue in DEV and QA environment. It is my production server.
The environment is HP-UX IA64 with oracle 10g.
Thanks in advance.

Hi Rajesh,
What stage is the installation hanging at ?
Please provide any error info from sapinst_dev.log
Check if java engine is installed and is up and running or not.. You could check the j2ee work directory under which you find j2ee stack related traces.
e.g. check std_server0 to see if the server is up or not
Please send more details

Java Add-In Installation for EHP4 ERP system

Hello!
we successfully upgraded our SAP ERP system to EHP4 for SAP.
Our system has only ABAP stack.
Question
1) Is it possible to install a Java Add-In instance for the existing EHP4 system?
2) If yes, can this be done on the same Windows server?
Thank you very much!

Specific Requirements
Take the following specific requirements of the new installation process into consideration:
- The previous SAPInst installation service Java Add-In in SAP ERP 6.0/SAP NetWeaver
7.0 was able to add Java usage types such as EPC, or EP, to existing ABAP-only

SAP Secure Store error at Java add-in installation

During the Java add-in installation, at phase "Install Java Engine", I get the error "A key/value pair with this key already exists in the store".
How can I fix it?
[ECC6]

Sorry for not making clear.
To uninstall java stack:
1. Drop the J2EE DB schema (the db schema for this one SAP SID). Be very
careful not to drop the DB schema for another existing system or the
ABAP system since it will destroy your data.
2. Remove DIR_GLOBAL/security/data
3. Remove DIR_INSTANCE/SDM
4. Remove DIR_INSTANCE/j2ee
5. Revert CI instance profile to their original state (backup copies
should exist in the profile directory)
6. Deinstall SCS using SAPinst
7. Restart ABAP
This should remove the java stack without affecting the ABAP system.
Then the correct order for installation will be:
1. Install Central Services Instance (SCS) Java Add-In
2. Install Database Instance Java Add-In
3. Install Central Instance Java Add-In
cheers,
Vincent

Hi Stefan,
This is one solution that i came across in an alternate thread,
"Not sure if this will help but..
All of my issues resolved around the Java engine (HEAP) not being able to reserve enough memory. Also, I found some of the default parameters in the config tool to be slightly incorrect.
So, I patched to the Java version C:\j2sdk1.4.2_08..I assume you have edited the profile parameter to include
jstartup/vm/home = <your jdsk> location
During the java install, failed at the IGS step (due to IGS running on the Abap stack), had to kill this process with
qprocess sapservice<SID> (look for the IGS processes)
sapntkill -INT pid pid pid (yes, I'm running Windows)
Then, the failure at the Java startup time. Numerous error messages like cj2-20057, or server0 would not start etc. I tried numerous attempts, eventually identifing that the Java parameters were not correct.
So...
Run the configtool.bat
For the instance_ID:-
Message Server and Bootstrap tab
256MB memory
no Java parameters set
Servers General Tab
Max heap size 256MB
-Xms128m
-XX:NewSize=32m
-XX:MaxNewSize=64m
-XX:NewRatio=3
-XX:+DisableExplicitGC
The DISPATCHER ID
General TAB
Ensure the max heap size is 64
-Xms64M
Bootstrap TAB
Max heap size 384
(no JAva parameters set)
the SERVER ID
General TAB
Max Heap Size 528
Java parameters as below....
-Xms528M
-XX:PermSize=192M
-XX:MaxPermSize=192M
-XX:NewSize=160M
-XX:MaxNewSize=160M
-XX:SoftRefLRUPolicyMSPerMB=1
-XX:SurvivorRatio=2
-XX:TargetSurvivorRatio=90
-verbose:gc
Bootstrap Tab
383MB
-no java parameters set
Shut down the Java stack in MMC, pressed the Retry button, and all was fine.
Hope this helps."

Can't start SAP after Java add-in installation

Hi,
We have migrated our BW 3.1C system to BI 7.0 (Win2003, Oracle 10.2, non-unicode). Everything was OK with the Abap system upgrade.

Java Add-In installation on a existing ABAP System (MSCS Cluster)

Hi all
we try to install a Java Add-In for a already existing ABAP System with
SAPinst. The ABAP System is a NetWeaver2004s SR1 System in a MSCS Cluster.
We have the Problem that we can´t choose the Installation Drive during
the SAPInst Define Parameter Step during the "Central Services Instance (SCS) Java Add-In" Installation.
But in the Installation Manual for
NW2004s Java AS in Chapter 4.3.2 is stated:
"Caution: You must install it on the same shared disk as the ASCS instance."
If I run the Installation, the SCS will be installed on the local disk E:
beside the Central Instance. But it need to be on the shared Disk P:
beside the ASCS installation. How can I control this?
Stefan

obviously the network share saploc is existing in your system an pointing to a local device.
Delete the local saploc share, install SCS instance, run MSCS first node, additional node, create the local share saploc again (don't forget to set permissions on the share, the default permission did only allow Read vor Everyone) and proceed with installation.
There is a note in creation for this issue.

Can not install a Java add-in installation

Hello,
I have installed a ABAP NW 7.0 EHP1 system with BI_CONT 704. But our BW people asked if I could install a J2ee add-in installation onto the ABAP system.
I u201Cthe old daysu201D I just started sapinst on the installation master, and then choose Java Addin installation, but this option is not available any more.
I tried this on the installation master: SAP Netweaver 7.0 Including Enhancement Package 1 Support Release 1 -> SAP Application Server JAVA -> MS SQL Server -> Central System
But when sapinst gets to the step where it asks me for the SAP instance u201CSAP System IDu201D, then I enter the running ABAP system, but after that I get the error u201CSAP system BW3 is an ABAP or ABAP+Java system. Cannot convert this to a Java standalone system. u201D
This confuses me, since I am not trying to convert anything, I am just trying to install a J2ee addin installation.
Anyone who can help?
Thanks in advance.
Kenneth

Hi,
Yes, as you discovered by yourself, the java add-in installation option was removed by SAP.
The java add-in was recommended a few years ago but due to all the problems it created it is now unsupported by recent installation sources.
From my personal experience, I agree that java add-in brings more problemas than advantages but if you really want to install one you will have to use older installation sources.

Java add on installation in ECC 6

Hi all,
We are having ECC 6 already in place and our client requirement is to install java add on the same in ECC instance. In the installation master I have selected the Netweaver system , followed by sap system and then java add in for abap system.
This is the step which i am following for java add in installation. I am not sure whether i am in the right process. Could you please suggest the porcess?
Regards
Vijay

Thanks Rohit,
For the immedite response.
In the phase of Java system RFC connection. I have provided the SAP SYSTEM LOG in details.
That is SAP client as : 300
DDIC password : password
The problem is not accepting by ddic passowrd and throwing an error by saying the password which you have provided is wrong. But i can able to log in sap level by using the same password in the same client.
Why is not accepting the password? Eventhough the password is right and also i can able to login in sap level.
I am sure about i didnt do silly mistakes like caps lock or mistyoing or key board issues. And also I have tried the standard passwords like 19920706,minisap and the master passwords.
After the third attempt in installation,m the user is get locked. I will unlock and will try again. Even I tried to change the password in sap level and its not working in the installation.
Anyone have any idea on this??
Kindly suggest
Thanks and Regards

What is an add-in installation?

hello friends,
to my understanding, a dual stack WAS install is when you do an java and abap stack install.
now i am seeing the term add-in installation to refer to both stacks. is dual stack and add-in the same?
i've run across some docs and they seem to say that add-in installation means an abap install and than a java stack was added. is this true?
cheers,
mike

Hi Mike,
Yes. Below is the link to the document from sap confirming this...
Search for the Add-in. You will find your self.

Change j2ee_admin username in add-in installation

hi,
is it possible to change the default administrator username from j2ee_admin to something else in a add-in installation? It is a NW2004s add-in installation.
Thanks, for your help.
best regards
thomas

Hi Viliana,
i have changed the admin user like described in your first link. It looks quite good, the j2ee engine of the double stack is running, i can connect, the sld is running correctly. But i had a strange effect in the visual admin during the configuration of the sld data supplier, so i was wondering if the documentation is only for standalone java installations and then i was not sure if the admin user in a double stack system has to have the user name j2ee_admin.
best regards
thomas
