11i/R12 Apache Common Issues with Solutions
Apache Common Issues
General Information to Troubleshoot Apache Issues.
1)If you mistype any directive in Apache (httpd.conf or any conf file), Apache will not start & it will not write even in error_log. In these case it will report any error message to file
$COMMON_TOP/admin/log/$CONTEXT_NAME/adapcctl.txt
So first check in the above file
2)Found *.pid file in Apache_Top/Apache/logs/ even after bounce of an Apache web server (When Apache starts it creates .pid file in logs directory and when you shutdown apache it cleans this .pid file). So if this file is already there then Apache will not start.
Fix: Simply move this file
3)Could not bind port (Port already in Use) or Sometimes apache and concurrent Manager will interchange their port no.’s while starting results error and both of them will not up
Fix: To overcome this up the services in this manner
1)Listener
2)Apache web server
3)Concurrent manager
4)adstrtal.sh
4)Error 500 – Internal server error
Fix: 1) Clear Cache (Application Server Cache)and start the services
5)If there are no error messages in error_log or error_log_pls
then there might be issues in starting Jserv component of web server (which caters Java requests by mod_jserv)
6)If you don’t know port number of your web server you can check it in file $IAS_ORACLE_HOME/Apache/Apache/conf/httpd.conf with directive Listen & Port
7)Once you are able to access http://hostname.domainname:port and if you are getting any error message that means your web server (Core Apache) is working but there are various components called as modules and there may be issues with those modules which we will check these modules . few modules of our interest are
-mod_jserv
-mod_pls
-mod_oprocmgr
-mod_ossl (If you have ssl enabled on web server)
-mod_osso (If single sign on server is enabled on web server)
8)Once in a while adapcctl.sh start will not work then ultimate you have to go and invoke apachectl script file in Apache top/apache/bin to start Apache webserver.
09)Error : Your session is no longer valid while trying to loging to applications.
The issue is resolved by changing the profile option session_cookie_domain to null from domain.com
10)HTTP-403 forbidden message after entering the username and password in the “Apps Logon Links” page. [Not authorised to view this page]
Check for Apps password in $APACHE_TOP/modplsql/cfg/wdbsvr.app ,Comment out custom_auth entry in $APACHE_TOP/modplsql/cfg/wdbsvr.app and bounce apache.
11)Error message: You have insufficient privileges for the current operation.
Verify and update SESSION_COOKIE_DOMAIN in ICX_parameters if it is wrong.
Example :
update icx_parameters set SESSION_COOKIE_DOMAIN=’NEW_VALUE’ where SESSION_COOKIE_DOMAIN=’OLD_VALUE’
12)AppsLocalLogin?.jsp page error outs….
- Edit the $IAS_ORACLE_HOME/Apache/Jserv/etc/jserv.properties
- Set wrapper.bin.parameters=-DLONG_RUNNING_JVM=false
- add the line wrapper.bin.parameters=-DCACHEMODE=LOCAL
- Restarted Apache for these changes to take effect and retested the issue
13) Login to the applications URL fails with
500 Internal server Error

Performed the below steps, but it did not resolved the issue
1) Bounced Apache server, cleared cache and validated ports
2) Bounced all Middle tier services and killed defunct processes
3) Bounced Unix Server
Solution
=======
Java object Caching Configuration parameter was Enabled in oc4j.properties
$INST_TOP/ora/10.1.3/j2ee/oacore/config
Disabled LONG_RUNNING_JVM=false from True
Bounced Apache server and could login to the applications URL without issues
ISSUES AND SOLUTIONS
ISSUE 1:
Description
When Apache script adapcctl.sh is issued.It shows that Apache is started.On checking the status Apache is stopped
Cause
The error log file in the folder
cd $APACHE_TOP/Apache/logs
Showed
fopen: No such file or directory httpd: could not log pid to file /var/opt/_/Apache/logs/
httpd_pls.pid
SOLUTION 1
Created the missing directories /_/Apache/logs under /var/opt folder
Bounced Apache

opmnctl status
ias-component process-type pid status
OC4J oacore N/A Down
OC4J oacore N/A Down
OC4J oacore N/A Down
OC4J oacore N/A Down
Cause
Check the oacore error log.
Example:
Below Log file gives root cause. //mtlog/_/logs/ora/10.1.3/opmn/oacore_default_group_2/
oacorestd.err
14:11:56 Error initializing server: //inst/apps/_/ora/10.1.3/j2ee/oacore/config/
server.xml,
Fatal error at line 70 offset 1 in file://inst/apps/_/ora/10.1.3/j2ee/oacore/config/
server.xml: .:
XML-20100: (Fatal Error) Expected 'EOF'.
SOLUTION 2
Edit the /sid/inst/apps/SID_hostname/ora/10.1.3/j2ee/oacore/
configserver.xml file and remove the extra line in the file. Restart and check oacore will be starting. This sudden change in
server.xml seems to be because of a bug.

Java object Caching Configuration parameter was Enabled in oc4j.properties $INST_TOP/ora/10.1.3/j2ee/oacore/config
Disabled LONG_RUNNING_JVM=false from True
Bounced Apache server and could login to the applications URL without issues
Java Caching is a mechanism used to improve performance by storing data in the Middle Tier JVM memory, instead of retrieving the data from the database every time it is requested.
***********************************************************************
ISSUE 9
When trying to access the URL (Either Big IP or the node level), it hangs for a long time and getting redirected to a different URL and gives a blank page. For example, When try to access the ipayments URL which is hosted on node2, it hangs for a long time and its getting redirected towards the Sales URL which is hosted on node3, and displays a blank page.
Cause
All the host reference and the URL directives are pointing towards node3 and sales URL respectively, in the below files. Hence every attempt tries to launch the sales URL and get fails as the apache configuration files and parameters are pointing towards the correct one.
jserv.conf forms.properties zone.properties jserv.properties
SOLUTION 9
Stop Apache. Edit the files
jserv.conf, forms.properties, zone.properties, jserv.properties,
jserv.conf to replace the host reference and the URL directives to the correct one (In our case, its node3 . Clear the cache and restart the Apache.
ISSUE 10

Clearing the Apache and Jserv cache did not resolve the issue. Unmount / mount product specific file system did not resolve
SOLUTION 13:
Try each of these solutions until the problem is resolved, in order to have the least impact on the system.
1. If you can determine the specific class file from the log files, use the ‘touch’ command.
e.g. touch classfile
If necessary, restart Apache and clear server cache.
2. Shut down all MT services, exit the Apps owner and ask the System Admin to unmount and remount the /sid/applmgr file system (mount point above $JAVA_TOP). Ask the System Admin to kill any processes that may be holding the file system open. Then log in to the Apps owner and restart MT services.
3. Shutdown all the MT services and ask System Admin to reboot the server if the actions above don’t resolve the outage.
