The issue is due to the fact that the script does not allocate adequate memory to the JAVA process.


To fix this backup the current script and amend the initial JAVA memory allocation (Xms) and maximum heap size (Xms) values to address the memory issues e.g.

MEM_ARGS=”-Xms512m -Xmx1024m -XX:+UseParallelGC”


MEM_ARGS=”-Xms2048m -Xmx2048m -XX:+UseParallelGC”


[applvis@z-oracle1 bsu]$ ./ -install -patch_download_dir=/u06/oracle/VIS/fs1/FMW_Home/utils/bsu/cache_dir -patchlist=EQDE -prod_dir=/u06/oracle/VIS/fs1/FMW_Home/wlserver_10.3
