The following shell script collects today's cache details of weblogic jvm and sends out an email.
The script can ssh to many linux servers and only collect cache details were cache has been created on the present day.
The servers should already have keyless SSH enabled between them
Below is the script
#!/bin/sh
echo -e "\e[0;36m++++++ \e[0m"
echo -e "\e[0;36m Author : robin.richard@****.com \e[0m"
sleep 5
echo -e "\e[0;36m++++++ \e[0m"
printf "\n ======================= \n Begining cache collection in PROD \n ======================= \n"
sleep 4
rm -r report.txt
printf "\n ======================= \n purging old data \n ======================= \n"
echo -e "\e[0;36m++++++ \e[0m"
sleep 5
#rm -r report.txt
for i in oracle@server oracle@server oracle@server oracle@server oracle@server; do ssh $i 'echo "Server: $(hostname) - Date: $(date)" && find /<path>/servers/*/tmp/_WL_user/ -daystart -ctime 0 -print' >> report.txt; done
sleep 4
printf "\n ======================= \n Completed Cache collection \n ======================= \n"
echo “ prod cache details” | mail -s “Prod_cache_details” robin.richard@****.com,rramaneedi@****.com,hsinghchouhan@****.com < report.txt
printf "\n ======================= \n Sending Email \n ======================= \n"
echo -e "\e[36;41m++++++ \e[0m"
printf "\n ======================= \n Exiting the system \n ======================= \n"
echo -e "\e[36;41m++++++ \e[0m"
You can also put the script in bash profile as follows
vi ~oracle/.bashrc
alias cachecollector='/home/oracle/cache_collector/robin.sh &'
also you can try
for i in oracle@server oracle@server oracle@server oracle@server oracle@server; do ssh $i 'echo "Server: $(hostname) - Date: $(date)" && echo -e "\e[0;36m++++++ \e[0m" && find /<path>/servers/*/tmp/_WL_user/ -daystart -ctime 0 -print | xargs ls -ltr && echo -e "\e[0;36m++++++ \e[0m"' >> report.txt; done
or
for i in oracle@server oracle@server oracle@server oracle@server oracle@server ; do ssh $i 'echo "Server: $(hostname) - Date: $(date)" && find /<path>/servers/*/tmp/_WL_user/ -daystart -ctime 0 -print' >> report.txt; done
or
for i in oracle@server oracle@server oracle@server oracle@server oracle@server ; do ssh $i 'echo "********" && echo "Server: $(hostname) - Date: $(date)" && find /<path>servers/*/tmp/_WL_user/ -daystart -ctime 0 -print && echo "********"' >> report.txt; done
Print index.html from todays date
find /<path>/*/index.html -daystart -ctime 0 -print
Print folders only of todays creation date
find /<path>/*/<path>s/*/tmp/_WL_user/ -mindepth 1 -maxdepth 1 -ctime 0 -print

REASON: javafx has been removed from java11, however it is still available in java8
so use JDK 8 version
Error : OpenJDK 64-Bit Server VM warning: Failed to reserve shared memory. (error = 1)
Context: this is a lucene solr 9.0.0 + zk 3.8.0. on a linux server
Solution:
increment the heap memory at SOLR_HEAP="24g" to accommodate increased collection load.

To Extract Private Key from a wallet we would need orapki keytool and openssl.
<<<<<<<<<< Display the contents of the wallet using orapki >>>>>>>>>

convert from pkcs12 to jks and provide password
