Monitoring Weblogic Datastore Connectivity

If weblogic application deployed seems to have intermittent issue of datastore errors, We can monitor the datastore ping to find the reason for database connectivity failure using below sample script that I used to monitor my database connectivity from the weblogic server.every 5 mins

.  /home/oracle/init_AJITH_wl.sh

while true()

do

java -classpath $WL_HOME/server/lib/weblogic.jar utils.dbping ORACLE_THIN apps ******* ajithpathiyil1.lab.com:1521:ajithpathiyil1 > /tmp/chknet.out

java -classpath $WL_HOME/server/lib/weblogic.jar utils.dbping ORACLE_THIN apps ******* ajithpathiyil1.lab.com:1521:ajithpathiyil1 >> /tmp/chknet.out

grep "**** Success!!! ****" /tmp/chknet.out

if [ $? -ne 0 ] then

cat /tmp/chknet.out | /bin/mail -s "Erec:Issue" ajithpathiyil@gmail.com

Oracle Apps R12: How To Renew SSL Certificate on Apps Tier in 5 minutes

1.      Set Your Environment

·         Logon to the application middle tier as the OS user who owns the middle tier files.

·         Source your middle tier environment file.

·         Navigate to the $INST_TOP/ora/10.1.3 and source the .env file to set your 10.1.3 ORACLE_HOME variables.

Note:- When working with wallets and certificates you MUST use the 10.1.3 executables.

2.      Deploy Certificate across Environment

export SYSTEM=ajiebs

export SSLDIR=/u01/app/applmgr${SYSTEM}/ssl_renew

export SSLENV=ajiebs.lab.com

mkdir -p $SSLDIR

chmod 700 $SSLDIR

3.      Copy new certificate and the CA certificate to the $SSLDIR directory e.g.

-rw-r--r--  1 applmgr oinstall 4198 Jul 26 10:30 chain.cer

-rw-r--r--  1 applmgr oinstall 1794 Jul 26 10:30 ajiebs.lab.com.cer

-rw-r--r--  1 applmgr oinstall  887 Jul 26 10:30 ajiebs.lab.com.key

4.      Create the wallet

cd $SSLDIR

$ORACLE_HOME/Apache/Apache/bin/ssl2ossl -cert ${SSLENV}.cer -key ${SSLENV}.key -cafile ./chain.cer -wallet . -ssowallet yes

5.      The content of wallet can be listed e.g.

orapki wallet display -wallet $SSLDIR

Requested Certificates:

Subject:        CN=ajiebs.lab.com,OU=Information Technology,O=Lab Inc.,L=Bangalore,ST=India,C=IN

User Certificates:

Trusted Certificates:

Subject:        CN=GTE CyberTrust Global Root,OU=GTE CyberTrust Solutions\, Inc.,O=GTE Corporation,C=US

Subject:        CN=ajiebs.lab.com,OU=Information Technology,O=Lab Inc., L=Bangalore,ST=India,C=IN

Subject:        CN=Lab Inc. Enterprise Issuing CA1,O=Lab Inc.

Subject:        CN=Lab Inc. Enterprise CA,O=Lab Inc.

6.      Determine the current Apache's wallet directory

·         Which is the value of s_web_ssl_directory + Apache, by default it's $INST_TOP/certs/Apache

·         Create a new directory named BAK and move the default wallet's files to there

·         Install the new wallet

cd $SSLDIR/../

mv ssl ssl_bak_`date +%Y`

mv ssl_renew ssl

Some features of XML Publisher and BI Publisher require the server certficate to be present in cacerts file.

7.      Backup the existing cacerts file.

cp $OA_JRE_TOP/lib/security/cacerts $OA_JRE_TOP/lib/security/cacerts.bak.`date +%Y`

8.      Add new server cert to cacerts:

chmod u+w $OA_JRE_TOP/lib/security/cacerts

keytool -importcert -keystore $OA_JRE_TOP/lib/security/cacerts -alias ${SSLENV}.`date +%Y`.lab.com -file ${SSLENV}.cer -v

9.      When prompted enter the keystore password.

10.  Restart APP Web Tier

11.  Restart oacore, forms, web listener processes
