Points good to know about JDK\/Java upgrade for 11i<\/strong><\/u><\/p>\n

1.<\/strong> Java Standard Edition (Java SE) was formerly referred to as Java 2 Standard Edition (J2SE) or the Java Development Kit (JDK).
\n2. <\/strong>Install Java 2 SDK (or JDK) and NOT JRE (java Run Time Environment)
\n3.<\/strong> Even if you are running apps on 64 bit server, download and install 32-bit Java (and NOT 64 bit)
\n4.<\/strong> To Upgrade to J2SE 5.0 minimum you should be minimum at 11.5.10 CU1 and
\nfor J2SE 6.0 minimum 11.5.10 CU2 or 11.5.9 CU2 with ATG RUP5<\/p>\n

Main steps for Java Upgrade for Oracle Apps 11i <\/strong><\/u><\/p>\n

1.<\/strong> Download and Install Java (J2SE\/JDK) on all apps nodes
\n2.<\/strong> Download and Apply interoperability patches using adpatch<\/strong> utility
\n3.<\/strong> Configure Application Tier Nodes to support J2SE 5.0 or 6.0 using txkrun.pl<\/strong>
\n4.<\/strong> Regenerate the appsborg2.zip File & Product JAR Files using adadmin<\/strong>
\n5.<\/strong> Restart Services using adstrtal.sh<\/strong>
\n6.<\/strong> Verify the Application Tier Node Configurations using aoljtest.jsp<\/strong> (http:\/\/[web server]:[port]\/OA_HTML\/jsp\/fnd\/aoljtest.jsp)<\/p>\n

.<\/p>\n

What happens in the background<\/strong><\/u><\/p>\n

When you run txkrun.pl<\/strong> -script=SetJDKCfg … where txkrun.pl is under\u00a0 $FND_TOP\/bin calls txkSetJDKCfg.pl<\/strong>
\n$FND_TOP\/patch\/115\/bin\/txkSetJDKCfg.pl -> This script is used to migrate FND <\/strong>and AD<\/strong> to new JDK<\/strong> version<\/p>\n

a.<\/strong> Backs up context file in $APPL_TOP\/admin\/$CONTEXT_NAME\/out\/<timestamp>\/
\nb.<\/strong> Updates following context variables in context file<\/p>\n

s_jdktop, s_afjretop, s_tools_java, s_oajretop, s_oajdktop, s_jretop<\/strong>\u00a0 to new JAVA_TOP
\ns_txk_jdbc_zip<\/strong> to jdbc14.zip
\ns_txk_wrapper_bin_charset_jar<\/strong> to charsets.jar
\ns_adovar_afclasspath, s_adovar_classpath<\/strong> to use jar, zip and java files from new JAVA_TOP
\ns_afjvaprg, s_adjvaprg<\/strong> to new JAVA_TOP\/bin\/java
\ns_jvm_options<\/strong> to -verbose:gc -Xmx512M -Xms128M -XX:MaxPermSize=128M -XX:NewRatio=2 -XX:+PrintGCTimeStamps -XX:+UseTLAB
\ns_adjreopts<\/strong> to -Xmx512M
\ns_java_awt_headless<\/strong> to true
\ns_afjcparg<\/strong> to -client
\ns_afjsmarg<\/strong> to -server<\/p>\n

c.<\/strong> Executes Autoconfig<\/strong> to update above changes in all configuration files<\/p>\n

Logs are in file $APPLRGF<\/strong>\/TXK\/txkSetJDKCfg_<timestamp>.log (where APPLRGF is $COMMON_TOP\/rgf\/$CONTEXT_NAME)<\/p>\n
