JPREPARE wont run - java.lang.OutOfMemory error

[Former Member]

Hi All

We are trying to upgrade our BW 3.5 system to BI 7.0. Currently we ahve an ABAP stack with a java add-on.

W have run ABAP PREPARE thru to Phase GETSYNC_PREUP_FINI_D. It has halted at a phase that now waits for the java side to be upgraded.

Our java version is:

java full version "J2RE 1.4.2 IBM AIX 5L for PowerPC (64 bit JVM) build

caix64142ifx-20061222 (ifix 113727: SR7 + 112603)"

When we start JPREPARE to upgraed the java stack we get the following error:

Waiting for SDTServer to connect on hostname rhubwp01/10.15.10.5 socket

Hi All

SAP have come back with a solution to this. The information below is a note, however, since the note has been archived you cannot access it via SAP Service Marketplace.

Symptom

You are upgrading to SAP NetWeaver 2004s (or Business Suite 2005)

lower than Support Release 1.

The Java upgrade process results in a java.lang.OutOfMemoryError. In the

trouble ticket of the phase and in the phase log files you can find the

error message: Error java.lang.OutOfMemoryError <null>

This exception can occur in different phases of the upgrade, but most

often it occurs in the DETECT_START_RELEASE_COMPONENTS phase.

Other terms

NetWeaver UPGRADE, Java Upgrade, OutOfMemoryError

Reason and Prerequisites

The reason of the error is that there is not enough memory for saving

the upgrade data into xml files. The upgrade saves its internal data in

xml files and the size of these files can become very large - bigger

then 10 MB. The XML Processor may run out of memory while it saves the

xml file, which causes the error.

Solution

The problem is solved with the upgrade to SAP NetWeaver 2004s Support

Release 1 and Business Suite 2005 Support Release 1.

If you are upgrading to SAP NetWeaver 2004s (or Business Suite 2005)

lower than Support Release 1, then increase the JVM used by the Java

upgrade:

1. Stop the upgrade tool

2. Modify jump or jump.bat script, which is located in <upgrade

dir>/exe directory

- -for windows open the file jump.bat and add the line

set JUMP_JAVA_OPTS="-Xmx512m",

after the line:

set

CLASS_PATH=%ROOTDIR%\lib\sdt_bootstrap.jar;%ROOTDIR%\lib\sdt_u

cp.jar

- -for unix/linux systems edit the file jump and add the line

JUMP_JAVA_OPTS="-Xmx512m"

after the line:

classpath="$rootdir/lib/sdt_bootstrap.jar:$rootdir/lib/sdt_ucp

.jar"

3. Restart the upgrade tool.

Thanks

Sam
