How to apply a patch to a Shared APPL_TOP or Apps Tier File System environment?



There are 2 sets of of TIER values in the context file.

One set is controlling services on the node and one set is controlling the AD utilities.
 In a shared application tier environment the following context values should all be set to yes....

 [applvision@apps log]$
egrep -i 's_isAdAdmin|s_isAdWeb|s_isAdForms|s_isAdConc|s_isAdFormsDev|s_isAdConcDev|s_isAdWebDev'
 $CONTEXT_FILE
         <TIER_ADADMIN oa_var="s_isAdAdmin">YES</TIER_ADADMIN>
         <TIER_ADWEB oa_var="s_isAdWeb">YES</TIER_ADWEB>
         <TIER_ADFORMS oa_var="s_isAdForms">YES</TIER_ADFORMS>
         <TIER_ADNODE oa_var="s_isAdConc">YES</TIER_ADNODE>
         <TIER_ADFORMSDEV oa_var="s_isAdFormsDev">YES</TIER_ADFORMSDEV>
         <TIER_ADNODEDEV oa_var="s_isAdConcDev">YES</TIER_ADNODEDEV>
         <TIER_ADWEBDEV oa_var="s_isAdWebDev">YES</TIER_ADWEBDEV>
[applvision@apps log]$


With all the above variables set to YES, adpatch will apply all files to this Apps Tier.

The following variables in each nodes respective context file represent the services that are actually running on the a node:- e.g

<TIER_DB oa_var="s_isDB">NO</TIER_DB>
<TIER_ADMIN oa_var="s_isAdmin">NO</TIER_ADMIN>
<TIER_WEB oa_var="s_isWeb">YES</TIER_WEB>
<TIER_FORMS oa_var="s_isForms">YES</TIER_FORMS>
<TIER_NODE oa_var="s_isConc">NO</TIER_NODE>
<TIER_FORMSDEV oa_var="s_isFormsDev">YES</TIER_FORMSDEV>
<TIER_NODEDEV oa_var="s_isConcDev">NO</TIER_NODEDEV>
<TIER_WEBDEV oa_var="s_isWebDev">YES</TIER_WEBDEV>
