• Not all the files and configurations are under autoconfig control anymore. WLS managed configuration files include:

• httpd.conf• admin.conf• ssl.conf• ...

• Change the value in WLS -> run adSyncContext.pl. -> run autoconfig

• adProvisionEBS.pl -> provision EBS settings to WLS• adRegisterWLSListeners.pl run in background and syncs values

between WLS and CONTEXT_FILE

Administration (IV): autoconfig

37

Administration (V)

• APPS password change - should be updated also in WLS datasource

• Shut down the application tier services• Change the APPLSYS password• Start AdminServer using the adadminsrvctl.sh script from

your RUN filesystem• Do not start any other application tier services.• Update the “apps” password in WLS Datasource as follows

38

Administration: Integrations

• Simplified Look & Feel• Better integration with OAM and OID• Build-in OHS and WLS• No need to install additional components• Add Webgate on top of R12.2 OHS• Add AccessGate wls managed server into EBS_Domain• Less complexity

39


Pub

Administration: Cloning

• Not much difference from R12.1• FMW_Home handled by WLS utilities• adpreclone.pl creates a clone stage of FMW_Home• adcfgclone builds new FMW_Home on target via WLS

utilities• dualfs option

• perl adcfgclone.pl appsTier dualfs• clone the Run and Patch file systems in a single operation

Patching


Pub

lic

Patching (I)• ADOP Initially introduced as revolutionary breakthrough in patching

mechanisms with zero downtime required for patching• It appears that downtime is still needed (10-20 minutes depending on

environment size, hardware resources, etc.)• downtime mode introduced gradually• hotpatch still exists

• official statement is that every R12.2 patch is online patch• exceptions• R12.2.6 release update (+downtime)• if Oracle states so

• built in merge option• patches under $PATCH_TOP (fs_ne)

Patching (III)• Download patch to $NE_BASE/EBSapps/patch directory $PATCH_TOP• Prepare the system for patching: $ source <EBS_ROOT>/EBSapps.env $ adop phase=prepare• Apply a patch $ adop phase=apply patches=<patch_list> merge=yes• After all patches have been successfully applied, complete the patching cycle: $ adop phase=finalize $ adop phase=cutover $ source <EBS_ROOT>EBSapps.env run $ adop phase=cleanup• Synchronize the technology level between patch and run file systems: $ adop phase=fs_clone

46

Patching: experiences• Overall patching time increased• Problems with Applications multi-node environments

• Do not enable multi-node during installation• Not possible to instantly allow patch to finish even if some object,

form or report failed• flags=autoskip

• abandon=yes restart=no -> restart from beginning• abandon=no restart=yes -> continue from failed point

• check adctrl before• forceapply
