how to utilise patches in weblogic in x.3.6 version and upwards to 12.1.one
Weblogic Smart Update utility (bsu) is used to employ patches in 10.3.half dozen and 12.1.1 version of weblogic.
Weblogic Smart Update utility (bsu) lies in $MW_HOME/utils/bsu/
BSU Utility stands for BEA Smart update utility
At present how to apply patches in weblogic in 10.3.six
0. cease the weblogic server
1.Showtime unzip the patch to {MW_HOME}/utils/bsu/cache_dir
Notation: You must make sure that the target directory for unzip has required write and executable permissions
for "user" with which the component beingness patched is installed.
Annotation downwards the patch ID by reading the read me
Description: ============ Oracle WebLogic Sever overlay patch for 10.three.half-dozen.0.190416 which requires WLS 10.3.half dozen.0.190416 PSU (Patch Number: 29204678 , Patch ID :U5I2) in the surround
2.Navigate to the {MW_HOME}/utils/bsu directory.
For Unix/Linux
bsu.sh -install -patch_download_dir=${MW_HOME}/utils/bsu/cache_dir -patchlist=<id> -prod_dir=$MW_HOME\wlserver_10.3 for Windows
bsu.cmd -install -patch_download_dir=${MW_HOME}/utils/bsu/cache_dir -patchlist=<id> -prod_dir=$MW_HOME\wlserver_10.3 
iii.If it gives any conflict with any patches already practical in the system , we tin can rollback the conflict the patch as below
For Unix/Linux
bsu.sh -remove -patchlist=<id> -prod_dir=$MW_HOME\wlserver_10.3
for Windows
bsu.cmd -remove -patchlist=<id> -prod_dir=$MW_HOME\wlserver_10.3
4.Once the patch is applied successfully, we tin can check for the practical patches using the below article
how to check patches applied in weblogic
5.If you receive below mistake while applying patches with BSU utility
Exception in thread "main" java.lang.OutOfMemoryError: GC overhead limit exceeded at java.lang.Class.getDeclaredMethods0(Native Method) at java.lang.Class.privateGetDeclaredMethods(Grade.java:2521) at coffee.lang.Course.getMethod0(Form.java:2764)
Following steps tin can be used
Increase the heap size to allow more memory and prevent an eventual "coffee.lang.OutOfMemoryError: GC overhead limit exceeded" fault:
Go to $WL_HOME/utils/bsu Prepare to edit the bsu.sh (for UNIX) or bsu.cmd (for Windows) Find the MEM_ARGS setting, e.g., the default as MEM_ARGS="-Xms256m -Xmx512m" Increment these values to a higher setting, e.g., MEM_ARGS="-Xms1024m -Xmx1024m"
Ensure MEM_ARGS are used in bsu script for the patch-client.jar to resolve "java.lang.OutOfMemoryError: Java heap space" error:
Look for the line: "$JAVA_HOME/bin/java" -jar patch-client.jar $* Change to the following to ensure the MEM_ARGS are passed: "$JAVA_HOME/bin/java" ${MEM_ARGS} -jar patch-client.jar $* 6.Start the weblogic Server
How to increment the patch application Performance
In instance patch application is taking lot of fourth dimension, we can do two things
1.We tin can upgrade to latest BEA Smart utility
Steps
a. Ensure yous are on WebLogic Server x.3.6
b. Ensure y'all have applied previously released Smart Update 3.3.0
Patch 12426828 SMARTUPDATE 3.iii INSTALLER PLACEHOLDER
This is for 10.3.vi even though it says 10.iii.5, (which was when it was initially released)
When you lot launch BSU, information technology will display the version when information technology is loading. If the server has internet access, then yous should be given the option to update Smart Update when y'all run the tool.
You may also run the post-obit command:
%WL_HOME%\utils\bsu\bin\bsu.cmd -version (for Windows) $WL_HOME/utils/bsu/bin/bsu/bsu.sh -version (for Unix/Linux)
two.Older PSU's that are no longer in employ may be deleted from the bsu cache_dir. This tin further speed up some processing.
iii.Y'all can effort increasing the memory human foot print
Go to $FMW_Home/utils/bsu.
Edit bsu.sh (for UNIX) or bsu.cmd (for Windows).
Here you volition find the post-obit: MEM_ARGS="-Xms256m -Xmx512m"
Increase these values every bit needed to 3 Gb or 4 Gb and boosted GCOverheadLimit parameter: for example, to
"-Xms3072m -Xmx3072m -XX:-UseGCOverheadLimit" or "-Xms4098m -Xmx4098m -Xx:-UseGCOverheadLimit"
