Apache Related Common Issues in R12 and 11i.

Apache Related Common Issues in R12 and 11i.


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09)Error : Your session is no longer valid while trying to loging to applications.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
java.lang.NoClassDefFoundError at

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
**********************************************************************
ISSUE 2:
Description
oacore was not comming up in the configurator node.
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.

ISSUE 6

After selecting the E-Business home page got internal server error Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.

Cause
Found that all the properties files as below
jserv.properties jserv_restrict.properties zone.properties zone_restrict.properties
were pointing to a dbc file name _.dbc
which was not physically present at the path
/sid/applmgr/11510/fnd/11.5.0/secure/_
$ cd //applmgr/11510/fnd/11.5.0/secure/_
$ ls .dbc
SOLUTION 6:
copied the file PROD.dbc
which was physically present at path
//applmgr/11510/fnd/11.5.0/secure/_
to the dbc file name which was being pointed by all the properties files
This resolved the issue.
**********************************************************************
ISSUE 7
Instance is very slow / inaccessible with a warning on login page:
Warning

Low-level logging is currently enabled. Your application will not perform as well while Low-level logging is on.
Cause
Logging was enabled through profile values:

FND: Debug Log Level — Statement
FND: Debug Log Module — %
SLA: Enable Diagnostics — Yes
FND Validation Level — Error
SOLUTION 7
1. Change these values to:
FND: Debug Log Enabled — No
FND: Debug Log Level — ( Blank )
FND: Debug Log Module — ( Blank )
SLA: Enable Diagnostics — No
FND Validation Level — None
2. Bounce Apache on all the MTs and clear Apache cache.

SOLUTION 8
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
Apache login issues occurs in multi MT environment. Unable to login to oracle applications.

Cause
Issue due to distributed cache.
SOLUTION 10
Set is_distributed to false in javacache.xml Bounce Apache.
ISSUE 11
Apache server is down. Apache logfile did not provide useful information.
Started the Apache server, but the Apache Web listener did not started.
1) Verified no log files (Apache,Jserv) crossed 2GB limit. error_log, access.log, mod_jserv
2) Veified that the port is listening (netstat -an |grep ) Apache port(httpd.conf), pls listener(httpd_pls.conf)
3) Verified that the Apache and Jserv configuration files are not changed recently httpd.conf & Jserv.conf
4) Shutdown all the Middle tier services and check for ipcs (semaphores) did not resolve the outage.
$ ipcs on application middle tier as Application user ap

Cause
No Cause Entered
SOLUTION 11
Rebooted the server and started the services. All services came back normal.

Verified that there are no log files that exceed 2GB limit (OS limit).
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.

Clone a Database Using a Hot Backup RMAN

Clone a Database Using a Hot Backup RMAN

Clone a Database Using a Hot Backup

    A) Take a hot backup of the SOURCE Instance

    To quickly take a hot backup , Refer to : Script-to-create-Script-to-take-Hot-Backup-of-Database

    B) Prepare the TARGET

    SHUTDOWN the target DATABASE and LISTENER
    Take backup and Remove the TARGET ORACLE_HOME and database

    C) Use tar to copy the ORACLE_HOME and the database (from the hot backup) to the TARGET system to replace the target system.

    On the Source : Create the tar files

    tar -cvf /tmp/ohome.tar <ORACLE_HOME location>
    tar -cvf /tmp/dbbkp.tar <Database Hot backup location>


    Copy or scp the tar files

    scp /tmp/ohome.tar oracle@192.168.2.131:/tmp/ohome.tar
    scp /tmp/dbbkp.tar oracle@192.168.2.131:/tmp/dbbkp.tar


    On the Target Intance :

    create the directories for the ORACLE_HOME and datafiles if it does not exist
    Extract the tar files

    cd <ORACLE_HOME location>
    tar -xvf /tmp/ohome.tar

    cd <datafile location>
    tar -xvf /tmp/dbbkp.tar



ON the TARGET

1 Login as target user user and Verify .profile and *.env file under $ORACLE_HOME
Make sure that the environment is set for the Target System.

cd $ORACLE_HOME
pwd

2 Check all oracle related file systems for user and group ownership

cd <TARGET file systems>
ls -l

Check user and group ownership : It should be proper


3 Modify the entries in the tnsnames.ora and listener.ora to have the Listner for the target instance

eg : My listener.ora - where target is dev
==================================

dev =
(ADDRESS_LIST =
(ADDRESS= (PROTOCOL= IPC)(KEY= EXTPROCdev))

)
)


4 In config.c, make sure the entries are pointing to target .

cd $ORACLE_HOME/rdbms/lib
ls -ltr config*
vi config.c
Take care of Group. It should be the group the target user belongs to :
#define SS_DBA_GRP "dbTARGET"
#define SS_OPER_GRP "dbTARGET"



5 Move config.o

cd $ORACLE_HOME/rdbms/lib
mv config.o config.o.old_18jul10


6 If this is RAC to NON-RAC Refresh, relink Oracle with rac_off

cd $ORACLE_HOME/rdbms/lib
make -f ins_rdbms.mk rac_off

If this step did not fail with fatal errors, proceed with :
make -f ins_rdbms.mk ioracle


7 Relink all the executables.

cd $ORACLE_HOME/bin
./relink all

8 Verify the Timestamp
ls -l $ORACLE_HOME/bin/oracle



9 Verify that you can run sqlplus “/ as sysdba” without prompting for any password.

sqlplus "/ as sysdba"
connected to idle instance


10 Set the init.ora paramters and create the destination directory location
To see the directories to be created and corresponding parameters to be modified, Refer to :
Create-a-Database-Manually-using-Create-Database-Script

11 Prepare the Control file script from the trace bacup taken on production.

vi TARGET_control.sql

a) ? Consider the resetlog portion of this script . Delete the noresetlogs section of the script.

b)? Old Entry - CREATE CONTROLFILE REUSE DATABASE "SOURCE" NORESETLOGS ARCHIVELOG FORCE LOGGING

? New Entry - CREATE CONTROLFILE REUSE SET DATABASE "SOURCE" RESETLOGS ARCHIVELOG

c) Change the location of Datafiles to point to the Target,
Replace all occurances of : SOURCE replaced by TARGET
Replace all occurances of : SOURCE replaced by TARGET

d) Remove the TEMP file entries ( keep a safe copy, for later use).
Keep a safe backup of Temporary creation part and redo logfile creation statements.
After this , you can remove all lines after characterset and semicolon.

e) Inspect the control file script
The number of Datafiles should match that in the source.
select count(*) from v$datafile at the source.

Similarily, number of copied Datafiles at the Target should match the definition in the script.

Example – of what you will be left with in TARGET_control.sql
STARTUP NOMOUNT;
CREATE CONTROLFILE REUSE SET DATABASE "TARGET" RESETLOGS ARCHIVELOG
MAXLOGFILES 32
MAXLOGMEMBERS 5
MAXDATAFILES 1024
MAXINSTANCES 8
MAXLOGHISTORY 1361

GROUP 1 (
'/TARGET/..../log01a.dbf',
'/TARGET/..../log01b.dbf'
) SIZE 200M,
GROUP 2 (

12 Create the Controlfile

$sqlplus "/ as sysdba"
@TARGET_control.sql

13 See archive log mode

SQL>ARCHIVE LOG LIST
Should show automatic archiving “Enabled” and “Archivelog” Mode

14 Recover the database

SQL> recover database using backup controlfile until cancel;

Enter the archive file location, when prompted.

Use the following query on SOURCE to get the list of archives needed to be recovered -
select THREAD#, SEQUENCE# from v$log_history where &1 between FIRST_CHANGE# and NEXT_CHANGE#;

Here – For the value for $1 to be given will come from the sequence returned by the command – “recover database using backup controlfile until cancel;” which you have given on TARGET


15 Open the DB with resetlogs
SQL> alter database open resetlogs;

When the DB opens, check for any missing files or files needed for recovery

SQL> select * from v$recover_file;
SQL> select * from v$datafile where name like '%MISS%';
Should not return any rows for these queries.

16 Shutdown the Database

17 Check for the Default Temporary file –

select * from database_properties where property_name = 'DEFAULT_TEMP_TABLESPACE';

Confirm that this TEMP.
If the default is not TEMP,
SQL>alter database default temporary tablespace TEMP

18. Create the Temp datafiles , using the commands taken from the control file.

ALTER TABLESPACE TEMP ADD TEMPFILE __________

Example - The commands will be similar to below
ALTER TABLESPACE TEMP ADD TEMPFILE '/TARGET/..../temp20.dbf'
SIZE 134217728 REUSE AUTOEXTEND ON NEXT 52428800 MAXSIZE 1800M;
ALTER TABLESPACE TEMP ADD TEMPFILE '/TARGET/..../temp19.dbf'
SIZE 134217728 REUSE AUTOEXTEND ON NEXT 52428800 MAXSIZE 1800M;
ALTER TABLESPACE TEMP ADD TEMPFILE '/TARGET/..../temp18.dbf'
SIZE 134217728 REUSE AUTOEXTEND ON NEXT 52428800 MAXSIZE 1800M;
ALTER TABLESPACE TEMP ADD TEMPFILE '/TARGET/..../temp17.dbf'
SIZE 134217728 REUSE AUTOEXTEND ON NEXT 52428800 MAXSIZE 1800M;

Verify dba_temp_files, for all the temp file entries added to TEMP

SQL> select file_name from dba_temp_files;

19 Update global_name

select * from global_name;
update global_name set global_name='TARGET.ORACLEOUTSOURCING.COM';
commit;

SQL> select * from global_name;

Clone an Oracle database using RMAN duplicate (same server)..



Clone an Oracle database using RMAN duplicate (same server)..

This procedure will clone a database onto the same server using RMAN duplicate.
  • 1. Backup the source database.
    To use RMAN duplicate an RMAN backup of the source database is required. If there is already one available, skip to step 2. If not, here is a quick example of how to produce an RMAN backup. This example assumes that there is no recovery catalog available:
rman target sys@<source database> nocatalogbackup database plus archivelog format '/u01/ora_backup/rman/%d_%u_%s';
 This will backup the database and archive logs. The format string defines the location of the backup files. Alter it to a suitable location.
  • 2. Produce a pfile for the new database
    This step assumes that the source database is using a spfile. If that is not the case, simply make a copy the existing pfile.

    Connect to the source database as sysdba and run the following:
create pfile='init<new database sid>.ora' from spfile;
This will create a new pfile in the $ORACLE_HOME/dbs directory.

The new pfile will need to be edited immediately. If the cloned database is to have a different name to the source, this will need to be changed, as will any paths. Review the contents of the file and make alterations as necessary.

Because in this example the cloned database will reside on the same machine as the source, Oracle must be told how convert the filenames during the RMAN duplicate operation. This is achieved by adding the following lines to the newly created pfile:
db_file_name_convert=(<source_db_path>,<target_db_path>)

log_file_name_convert=(<source_db_path>,<target_db_path>)
Here is an example where the source database scr9 is being cloned to dg9a. Note the trailing slashes and lack of quotes:
db_file_name_convert=(/u01/oradata/scr9/,/u03/oradata/dg9a/)

log_file_name_convert=(/u01/oradata/scr9/,/u03/oradata/dg9a/)

  • 3. Create bdump, udump & cdump directories
    Create bdump, udump & cdump directories as specified in the pfile from the previous step.
  • 4. Add a new entry to oratab, and source the environment
    Edit the /etc/oratab (or /opt/oracle/oratab) and add an entry for the new database.

    Source the new environment with '. oraenv' and verify that it has worked by issuing the following command:
echo $ORACLE_SID
If this doesn't output the new database sid go back and investigate why not.
  • 5. Create a password file
    Use the following command to create a password file (add an appropriate password to the end of it):
orapwd file=${ORACLE_HOME}/dbs/orapw${ORACLE_SID} password=<your password>
  • 6. Duplicate the database
    From sqlplus, start the instance up in nomount mode:
startup nomount
Exit sqlplus, start RMAN and duplicate the database. As in step 1, it is assumed that no recovery catalog is available. If one is available, simply amend the RMAN command to include it.
rman target sys@<source_database> nocatalog auxiliary /



duplicate target database to <clone database name>;
This will restore the database and apply some archive logs. It can appear to hang at the end sometimes. Just give it time - I think it is because RMAN does a 'shutdown normal'.

If you see the following error, it is probably due to the file_name_convert settings being wrong. Return to step 2 and double check the settings.
RMAN-05001: auxiliary filename '%s' conflicts with a file used by the target database
Once the duplicate has finished RMAN will display a message similar to this:
database opened

Finished Duplicate Db at 20-SEP-14



RMAN> exit RMAN.

  • 7. Create an spfile
    From sqlplus:
create spfile from pfile;



shutdown immediate


startup
 
Now that the clone is built, we no longer need the file_name_convert settings:
alter system reset db_file_name_convert scope=spfile sid='*'

/



alter system reset log_file_name_convert scope=spfile sid='*'

/
  • 8. Optionally take the clone database out of archive log mode
    RMAN will leave the cloned database in archive log mode. If archive log mode isn't required, run the following commands from sqlplus:
shutdown immediate

startup mount

alter database noarchivelog;

alter database open;
  • 9. Configure TNS
    Add entries for new database in the listener.ora and tnsnames.ora as necessary.
