EBusiness 11i/R12 - Daily
Checks (for Apps. DBA) - Admin Node:
|
As Oracle Apps DBA / Sysadmin you Apply patches & restart servives
or make some configuration changes in applications 11i before releasing
Instance to Application Users you wish to check if all components in
E-Business Suite 11i are working fine. Here is list of components you should
check apart from your custom services.
1. Check Web
Server is Up : Check in browser
http://hostname.domainname:port where hostname.domain name is Machine Name on
which Web Server(OHS) is running. If you are using load balancer or Proxy
Server in front of Web Server it will be loadbalancer / Proxy Server
Name. Port is port on which Web Server is Listening. It is
defined in $IAS_ORACLE_HOME /Apache /Apache /conf /httpd.conf , To find more
about WebServer & its parameters
Oracle Web Server also called as OHS (Oracle Http Server)
or Oracle-Apache is built on Apache Webserver.
Oracle has added few custom component (like mod_plsql, mod_osso...) in Apache
webserver & shipped it as Oracle Http Server.
Discussion in this page is currently w.r.t. Oracle Http Server
Version 1.0.2.2.2 which is shipped with 11i (11.5.8-10). In coming weeks I'll
add 10G Application Server Integration with Oracle Applications 11i.
Oracle Web Server or OHS is entry point in applications, It
processes requests coming from network over Client. There is Web Listener
listening for Web Requests. If request is for simple html page core Apace
returns HTML page but if URL refernced need further processing it will be
forwarded to respective module like mod_pls, mod_jserv ... I will start with
basics like how to start stop webserver, important directories & files ,
troubleshooting , tuning & important things to know in oracle applications
E-Business suite Webserver.
How to Start/Stop Web Server All startup shutdown scripts in Oracle Applications
11i(11.5.10) are in $OAD_TOP/admin/script/$CONTEXT_NAME where OAD_TOP is also
called as COMMON_TOP and CONTEXT_NAME is your SID_hostname , lets say your
SID or Instance Name is VISION and its on machine with name machine1 so your
CONTEXT_NAME will be VISION_machine1. Script to start/stop Web Server is adapcctl.sh where ad (application dba), apc(apache), ctl(control) and
sh stands for shell script. (You will find this script only on node on which
you have webserver, if you have multi mode Installation and node 1 is only
for Concurrent Manager, Reports & Database and node2 is webserver &
forms then adapcctl.sh should be on node2 & not node1) adapcctl.sh callsapachectl(shellscriptin
$IAS_ORACLE_HOME/Apache/Apache/bin) which in turn calls HTTPD (in same directory which is executable called http daemon)
it starts using configuration filehttpd.conf (from $IAS_ORACLE_HOME/Apache/Apache/conf directory , this
file calls other configuration file. To know all important configuration file
follow config files link)
.
If you can't access this check error_log at $IAS_ORACLE_HOME /Apache /Apache/
