Heap Dump files not generated

Hi,

We have followed SAP Note 1053495 to generate Heap dump on IBM AIX server. However after doing all the steps mentioned in Note, *.phd files are not generated as per the note.

Please help .... as we need these logs for analysis purpose.

Hi Amol,

Did you followed the point no:- 2 of SAP note :- 1053495

This is because you are using classical version of Java.

Hi Anil,

Yes, we have followed the instructions of set 2 only.

Below is the java env file :

1. @(#) $Id: //bc/700-1_REL/src/ins/SAPINST/impl/tpls/ind/ind/J2EEENV.CSH#8 $ SAP

2. SAP J2EE Environment - please do not edit

3. check for running user

set USER = `id | awk -F\( '{print $2}' | awk -F\) '{print $1}'`

set TRUL = 'tr "ABCDEFGHIJKLMNOPQRSTUVWXYZ" "abcdefghijklmnopqrstuvwxyz"'

set SIDADM = "`echo $SAPSYSTEMNAME | $TRUL`adm"

if ( "$USER" == "$SIDADM" ) then

setenv JAVA_HOME /usr/java14_64

foreach d ( $JAVA_HOME/bin )

set i=0

foreach p ( $path )

if ( "$p" == "$d" ) then

set i=1

break

endif

end

if ( $i == 0 ) then

set path = ( $d $path )

endif

end

endif

switch (`uname`)

case AIX*:

if ( "$USER" == "$SIDADM" ) then

setenv IBM_JAVA_OPTIONS "-Xmx256M -Xj9"

else

setenv IBM_JAVA_OPTIONS "-Xmx256M"

endif

breaksw

case OS\/390:

setenv IBM_JAVA_OPTIONS "-Xmx256M"

breaksw

case Linux*:

set i=0

foreach p ( `uname -a` )

if ( "$p" == "s390x" ) then

set i=1

break

endif

end

if ( $i == 1 ) then

setenv IBM_JAVA_OPTIONS "-Xmx256M"

endif

breaksw

endsw

setenv IBM_HEAPDUMP "true"

Hi,

Everything look fine, did you logoff and login again and restarted the java application to take effect of change in environment variable.

Thanks
