Oracle 10g AS R2 Webcache error - Permission denied when setting group ID

Objective: On startup of the Oracle 10g AS R2 middle tier, we got the following errors. Error --> Process (pid=9185) failed to start a managed process after the maximum retry limit Log: /u04/ora9i/ora10gAS/mtier/opmn/logs/WebCache~WebCache~1 And when we checked from the Enterprise Manager and opmn status command, it was showing that Portal and WebCache failed to start. CookBook: When we checked the event.log file under $ORACLE_HOME/webcache/logs directory it was showing the following messages.

Oracle APPS R12 Post Cloning issue - Form not launching

Introduction:
We faced one of the issue, after successfull cloning of APPS R12.1.1, when we tried to open the form, it was not launching.

CookBook:

We did the following steps, and form started coming up.

1- Stopped the APPS Tier services.

2- rename the directory "tldcache" under following directories.

a- /binaries/INST_NAME/inst/apps/INST_NAME_MACHINE_NAME/ora/10.1.3/j2ee/oafm

b- /binaries/INST_NAME/inst/apps/INST_NAME_MACHINE_NAME/ora/10.1.3/j2ee/oacore

c- /binaries/INST_NAME/inst/apps/INST_NAME_MACHINE_NAME/ora/10.1.3/j2ee/forms

3- create the emplty directory with the name "tldcache" under the above directories.

4- restart the APPS Tier services.

5- test the issue.

how to restart the failed APPS R12 installation

Objective: In this post we will show how can we restart the failed APPS R12 installation. Cookbook: The installation can fail becuase of any reason, e.g. system hang, system restart etc. In any of the case we can restart the installation from the same point where it got failed. Following are the points. 1- start the rapidwiz with the option "-restart" ./rapidwiz -restart 2- it will open the install screen and will as the saved configuration file. Here is the catch, the saved configuration file can be found on two places. a- /tmp/MMDDHHMI/conf_SID.txt b- $ORACLE_HOME/appsutil/conf_SID.txt 3- once you choose the right saved configuration file, the installer will start from the same point where it got failed.

dbc file recreation for Oracle APPS R12

Introduction: In this post, we would see how can we create the "dbc" file, if it is missing for some reason. Cookbook: The "dbc" file location in Oracle APPS R12 is $FND_SECURE. If for some reason it is missing or invalid, then it can be recreated. Following is the command which can be used to recreate the "dbc" file. java oracle.apps.fnd.security.AdminAppServer apps/apps ADD FNDNAM=apps GWYUID=applsyspub/pub TWO_TASK=VIS SECURE_PATH=$FND_TOP/secure GUEST_USER_PWD=guest/oracle APPS_JDBC_DRIVER_TYPE=THIN DB_HOST=appsdemo.test.com DB_PORT=1531 The only thing needs to be taken care is replace the values with respect to the environment, like the values for $FNDNAM, hostname, port number etc.

Enterprise Manager DB Console set up for Oracle APPS R12 database 11g

Introduction:
In this article we will configure the Enterprise Manager DB console for Oracle 11g database for Oracle APPS R12.

CookBook:
Following points needs to be done.
1- Check for the "sysman" schema in 11g database, if it exist then it means there should be DB Console setup, to check this we can run the following statement,
$ emctl start dbconsole
if this successfull start the DB console then it means the EM DB console has already been configured, and if this statement returns any error, then better to resolve the issues or we can drop and recreate the DB Console. But before dropping the DB Console better to take the backup for the configuration files and database repository.

2- To drop the existing DB Console setup, we can use the following command.

/bin/emca -deconfig dbcontrol db -repos drop

This command will drop both the configuration files and database repository, and if this command is not working for some issues, we can go with manually deletion of the configuration files and database repository. Following commands can be used for manual deletion.

a- To drop the database repository
Step 1: Drop AQ related objects in the SYSMAN schema
Logon SQLPLUS as user SYSMAN
SQL> exec DBMS_AQADM.DROP_QUEUE_TABLE(queue_table=>'MGMT_NOTIFY_QTABLE',force =>TRUE);

Step 2: Drop the DB Control Repository Objects
Logon SQLPLUS as user SYS or SYSTEM, and drop the sysman account and management objects:
SQL> SHUTDOWN IMMEDIATE;
SQL> STARTUP RESTRICT;
SQL> EXEC sysman.emd_maintenance.remove_em_dbms_jobs;
SQL> EXEC sysman.setEMUserContext('',5);
SQL> REVOKE dba FROM sysman;
SQL> DECLARE
CURSOR c1 IS
SELECT owner, synonym_name name
FROM dba_synonyms
WHERE table_owner = 'SYSMAN';
BEGIN
FOR r1 IN c1 LOOP
IF r1.owner = 'PUBLIC' THEN
EXECUTE IMMEDIATE 'DROP PUBLIC SYNONYM 'r1.name;
ELSE
EXECUTE IMMEDIATE 'DROP SYNONYM 'r1.owner'.'r1.name;
END IF;
END LOOP;
END;
/
SQL> DROP USER mgmt_view CASCADE;
SQL> DROP ROLE mgmt_user;
SQL> DROP USER sysman CASCADE;
SQL> ALTER SYSTEM DISABLE RESTRICTED SESSION;

b- To drop the configuraiton files

/
/oc4j/j2ee/OC4J_DBConsole__

3- now we can use the following command to create the database repository and configuration files for DB Console.


-bash-3.00$ emca -config dbcontrol db -repos recreate
^C-bash-3.00$
-bash-3.00$
-bash-3.00$
-bash-3.00$ emca -config dbcontrol db -repos create

Oracle 9i Application Server R2 X-Server change

Introduction:
For Oracle 9i Application Server R2, there is requirement for the X Server, reports needs to have the X Server to run successfully, in this article we will see how to change the X Server from one machine to other machine.

Cookbook:
The X Server can easily be changed for the reports server, also there are many X Server available, the one is VNC X Server.

For Oracle 9i Application Server R2, there are 2 configuration files which needs to be altered if the X Server loaction has changed.

Follwing are the 2 files.
- reports.sh
- oc4j.properties

The location for the reports.sh is $ORACLE_HOME/bin/ and for the oc4.properties is $ORACLE_HOME/j2ee/OC4J_BI_Forms/config/.

Once the above files have been altered, then reports services needs to be restarted either from the Enterprise Manager or from the command line.

From the command line, we can start the reports servecis as follows..

$ORACLE_HOME/bin/rwserver.sh server=rep_machinename

Oracle APPS 12 (12.1.1) installation on Oracle Enterprise Linux R4 ( update 7) on Vmware server

Introduction:
This article is related to the installation of Oracle APPS 12 (12.1.1) on Oracle Enterprise Linux R4 on Vmware Serv er.

Cookbook:
We used the following software.

1- Oracle APPS 12 (12.1.1)
this can be downloaded from http://edelivery.oracle.com
2- Oracle Enterprise Linux R4 (update 7)
3- Vmware Server

Following are the steps which we followed. Also this article is not related to the installation of Vmware Server and Oracle Enterprise Linux R4. We will concentrate only on APPS 12 installation.

1- Following rpm(s) needs to be installed on Oracle Enterprise Linux R4, we installed only the bold ones, as only those were missing for this release.

net.core.wmem_max 262144

3- Following OS utilities should exist.
ar
gcc
g++
ld
ksh
make
X Display Server

4- we also need to create 2 OS users i.e. oracle to own oracle database and applmgr to own apps tier.

5- For this test installation we can create only one directory i.e. /d01/oracle, this would contain the db tier and apps tier.

6- After creating the stage from the APPS 12 media, we can run the rapidwiz installer and following screens show the steps to be followed. And hopefull it would go very smooth, without any problms.

This last screen shows that APPS 12 has been installed successfully, we can use the sysadmin username with the same password and can run any request to check the forms and concurrent manager.
