WF Mailer Not able to start with the following error : FRAMEWORK_USER=Unable to make a connection with the user and responsibility

October 15, 2019, 9:21 am
$

0
Scenario:

I was trying to restart the WF Container using the following Navigation in 12.1.3

Oracle Application Manager -> Workflow ->Service Components ->Workflow Notification Mailer

When we go inside the container and restarts it failed and shows the following error when we click on the Workflow Notification Mailer.


Error :

Could not handle the control event -> oracle.apps.fnd.cp.gsc.SvcComponentContainerException: Could not start component; performing rollback -> oracle.apps.fnd.cp.gsc.SvcComponentException: Validation failed for the following parameters -> {FRAMEWORK_USER=Unable to make a connection with the user and responsibility}. Parameters were -> {RESET_NLS=N, FROM=Workflow Mailer Production, INBOUND_MAX_RET_EMAIL_SIZE=100, CANCELED=WFMAIL:CANCELED, SEND_UNSOLICITED_WARNING

Solution:

The Error indicates connectivity problem, and the notification mailer will attempt to make a connection as SYSADMIN with the system administrator responsibility. So verify the following:
1. SYSADMIN userid is active and the responsibility System Administrator is Active.
2. Also check whether sysadmin has the default value by :

select * from fnd_user_a  where USER_ID='0' order by 1 desc;

In my case SYSADMIN user was end dated by mistake. Because of that it fails to start the WF mailer. So we removed the enddate and tried restarting and it worked.


Reference:

Workflow Mailer Is Not Coming Up And Agent Listeners In Unavailable State FRAMEWORK_USER=Unable to make a connection with the user and responsibility (Doc ID 2448179.1)

Recreation / Rebuild of Reporting database (for the EBS customers using Shareplex replication)

October 16, 2019, 11:34 pm
$

If you have Reporting database configured for your UAT or Pre-Prod instance , you may have to recreate/re-configure the reporting database associated with them after a database refresh.


Here I have given a detailed list of Steps to re-build your reporting database (replication database) and configure shareplex replication after Primary database refresh (UAT/Pre-Prod) .

Non-EBS users , please follow only the Database related steps 

1
Shutdown shareplex on both SOURCEDB & TARGETDB.
2
Take a backup of $vardir of Shareplex in both SOURCEDB & TARGETDB
3
Take a backup of Existing TNS Entries of SOURCEDB & TARGETDB on both the DB nodes before SOURCEDB clone.
4
Take a backup of existing Pfile along with the complete DBS Folder.
5
Take a backup of existing XML file of TARGETDB . (Very important)
6
Comment (#) the Apps RSYNC cronjob on SOURCEDB Apps server.
7
Once the SOURCEDB refresh is complete, Create TARGETDB DB as a standby of SOURCEDB and make sure it is in sync until we decide on downtime of SOURCEDB to configure TARGETDB & shareplex.
8
Copy the Application Filesystem from SOURCEDB to TARGETDB
9
Once the downtime is decided, Shutdown SOURCEDB Apps + DB and do not start until TARGETDB & Shareplex are configured.
10
Break the sync and Activate the Standby Database as Read/Write mode.
11
Open the Standby database.
12
Change the Standby database name to TARGETDB using NID.
13
Start TARGETDB as RAC on src_01 & tgrt_01
14
Make sure only 2 redo log Threads are enabled, otherwise you will encounters errors during shareplex config
15
Perform rest of the DB post clone and Apps clone steps. (as part of post clone do not mask email addresses & do not do any WF steps)
16
Start SOURCEDB DB
17
Run ora_cleanup (oracle@src_01/tgrt_01: cd $proddir/bin # ./ora_cleansp) in both SOURCEDB & TARGETDB
18
Drop & Recreate SPLEX schema with SPLEX & SPLEX_TEMP as default Tablespace & Temp tablespace respectively.
19
Cleanup & recreate SPLEX_TEMP tablespace
20
Disable Triggers in TARGETDB  (Create a script to disable them from the schemas that are part of replication config)
21
Disable Constraints in TARGETDB  (Create a script to disable them from the schemas that are part of replication config)

Note : Collect Dictionary stats before disabling constraints , to get better performance during disabling
SQL> exec dbms_stats.gather_dictionary_stats(options => 'GATHER');
22
Run ora_setup (exactly as per the attached notes)
23
Create Config using the existing config file itself on SP Source  
24
on SP Source, Disable the Sequence replication : set param  SP_OCT_REPLICATE_SEQUENCES 0
25
on SP Source , Enable DDL replication : set param SP_OCT_REPLICATE_ALL_DDL 1
26
on SP Source , increase Thread count : set param SP_OCF_THREAD_COUNT 9
27
Start Shareplex services on both Source & Target
28
Verify Config :  verify config REP_CONFIG_12JUL19 (config name may vary)
29
Activate Config : activate config REP_CONFIG_12JUL19 (config name may vary)
30
Start SOURCEDB Apps
31
Run Autoconfig on TARGETDB Apps
32
Start TARGETDB Apps

When applying OPatches to our Oracle database, we frequently encounter conflicts with the existing patches in our database  and we raise an SR with Oracle support to get a merge patch to resolve the conflict (also, we want to retain the old patch with which conflict arised.)

We all know this cannot be a Sev1 and it takes time to get a solution . To avoid the wait time for a merge patches through an SR , Oracle has come up with this new self help tool called " OPatch Conflict Checker " - using this we can get a merge patch for Opatch conflicts – without raising a request to Oracle Support .

Follow the below instructions on how to get a merge patch using this "OPatch Conflict Checker" :

DBA Tip : RMAN restore when backup file are spread across 2 different mount points

Customers whose databases are of huge size and if the RMAN backup size is about 2TB or more and when there is no enough space to keep all of the backup files in a single mountpoint , we spread them in 2 or 3 different mount points.

Question is "How do we restore when the RMAN backup files are in different location" ?

A simple solution to this would be to create softlinks to the backup pieces from location B in the  location A :


In my case,  the database Rman Backup files are spread across 2 different mount points in the Target ( /u02 & /u03)  and  as we cannot pass two locations to the Rman Duplicate command ... I’ve created softlinks in  /u02 to the backup pieces in /u03 and passed /u02 as a single backup location to RMAN script.

Example:

cd  /u02/backup/location1

ln -s /u03/backup/location2/PROD_df_full_143926_1.bak PROD_df_full_143926_1.bak
ln -s /u03/backup/location2/PROD_df_full_143927_1.bak PROD_df_full_143927_1.bak
ln -s /u03/backup/location2/PROD_df_full_143929_1.bak PROD_df_full_143929_1.bak
ln -s /u03/backup/location2/PROD_df_full_143936_1.bak PROD_df_full_143936_1.bak
ln -s /u03/backup/location2/PROD_df_full_143935_1.bak PROD_df_full_143935_1.bak


Now, It would look like :

cd  /u02/backup/location1
ls -lrt

FINP01_df_full_143925_6.bak
FINP01_df_full_143930_6.bak
FINP01_df_full_143931_4.bak
FINP01_df_full_143931_2.bak
FINP01_df_full_143931_3.bak
FINP01_df_full_143926_1.bak -> /u03/backup/rbackup/FINS01/FINP01_df_full_143926_1.bak
FINP01_df_full_143927_1.bak -> /u03/backup/rbackup/FINS01/FINP01_df_full_143927_1.bak
FINP01_df_full_143929_1.bak -> /u03/backup/rbackup/FINS01/FINP01_df_full_143929_1.bak
FINP01_df_full_143936_1.bak -> /u03/backup/rbackup/FINS01/FINP01_df_full_143936_1.bak
FINP01_df_full_143935_1.bak -> /u03/backup/rbackup/FINS01/FINP01_df_full_143935_1.bak

Now, pass '/u02/backup/location1' as the backup location to RMAN duplicate command :

DUPLICATE TARGET DATABASE to <TARGETDB>  BACKUP LOCATION '/u02/backup/location1' NOFILENAMECHECK ;

Database Configuration Assistant was not showing the database

Database Configuration Assistant was not showing the database and  Configure Database Options and it was disabled.
 
 We tried setting up ORACLE_SID and ORACLE_HOME and ran dbca but it was not showing the database and the above option was  greyed out.

We checked and verified the oratab file for correct entry for the database we were trying to access from dbca but still it was greyed out.

To resolve this issue I utilized all my experience and knowledge at last was able to resolve it. The issue was simple and silly but sometimes small things matter.

Below are steps used to resolve this issue:

Step 1:

Make sure the ORACLE_HOME is some thing like below : /u01/app/oracle/12.1/dbhome in /etc/oratab file

(Note we should not have '/' after dbhome)

Step 2:

Check the value of the configuration of  RAC Database:

srvctl config database -d testdb1

Where: testdb1=> DB Name.

Now change the ORACLE_HOME value as below:

srvctl modify database -o /u01/app/oracle/12.1/dbhome

Where:  /u01/app/oracle/12.1/dbhome=> ORACLE HOME location.

Make sure you don't use '/' after dbhome.

Step 3:

Now launch 'dbca' bye setting correct Environment.

Now you should see the option enabled for Configure Database Options after launching dbca.

Below are the steps required to be done in order to migrate Oracle ERP Applications from one server to another. These steps are successfully tested in my Test Oracle ERP Servers.

Note 1: My source and Target Environment is EBS 12.1.3
Note 2: This is applicable for Windows 2008 R2 server but somewhat similar steps can be applicable to Windows 2012 R2 or Windows 2016 server)
Note 3:All the steps are done on the Target Application Server
Note 4:Make sure you change the source server name and assign the same name to target Windows server in order to have backup of source Application server and not much changes is required in CONTEXT FILE if you have same Drives on Source and Target Application server.
Note 5: Please change server names,Directory structure and Environment files based on your servers.
as one need to spend some time in order to do this activity successfully.

Preparatory Steps:

1. Install MKS Toolkit on Target Server( we can also install CYGWIN ) . It is recommended to install MKS from Oracle Support.
2.Install VISUAL Studio of same Windows OS version(2008 R2).

Planning and Execution Steps:

1.Shutdown Oracle ERP Applications(adstpall.sh) Source(ERP APPLICATIONS)
Command prompt Run As Administrator: Source Env file APPSERP.env
cd $ADMIN_SCRIPTS_HOME
./adstpall.sh


2.Check firewall and connectivity from DB to Apps Tier and verify the port is open using telnet on Target(ERP APPLICATIONS)

telnet hostname port
telnet testhost 1521
connected means it is working fine, if it says trying add the firewall rules and allow port and try again.

3.Copy Apps Files from Source to target Target Server (Initiate copy From Target Server)

4.Modify PATH Environment variable to execute perl K:\oracle\apps\tech_st\10.1.3\perl\5.8.3\bin\MSWin32-x86-multi-thread; => In First line and remove rest of the variables if exists.
5.Change compatibility to Windows Server 2003 SP1 in K:\oracle\apps\tech_st\10.1.2\oui\bin for setup.exe 

6.Change compatibility to Windows Server 2003 SP1 in K:\oracle\apps\tech_st\10.1.3\oui\bin for setup.exe
7.Make sure INST_TOP is renamed on new Target(ERP APPLICATIONS)

(Run as Administrator on new command prompt).
cd K:\oracle\apps\apps_st\comn\clone\bin
 Execute  perl adcfgclone.pl appsTier
8.Verify logs of adcfgclone and confirm no errors exists.
adcfgclone logs Applications tier:

$COMMON_TOP/clone/bin/CloneContext_<timestamp>.log
This log shows the entries selected during execution of adcfgclone command

9.Execute autoconfig on Apps Tier and copy env file APPSERP_testhost.cmd from backup to APPL_TOP

cd $ADMIN_SCRIPTS_HOME
./adautocfg.sh

10.Replace ADMIN Directory(K:\oracle\inst\apps\ERP APPLICATIONS_testhost\ora\10.1.2\network) with admin_bkp and Reboot the Target(ERP APPLICATIONS)
11.Compare Services properties in old and new server and set accordingly. Restart the new Target (ERP APPLICATIONS) Application server

12.Compare Firewall rules in old and New  PROD Apps servers and copy accordingly and Validate with telnet

13.Execute cmclean(K:\oracle)
14.Start the Applications (adstral.sh) Target (ERP APPLICATIONS)

cd $ADMIN_SCRIPTS_HOME
./adstral.sh

Post Execution and Sanity Checks:
1.Configure Oracle Workflow inbound and outbound server settings and validate workflow mailer is up and running and test mailer
2.Complete Sanity checks for Database ,Applications, Concurrent Programs ,SSO and Workflow Mailer

2. On the RUN file system, start up admin server via the following command
. <EBS_ROOT>/EBSapps.env run
cd $INST_TOP/admin/scripts
$ adadminsrvctl.sh start
Ensure the Weblogic Admin Server and Node Manager are running on the Run File
system. You can run the following commands to check the status:
$ adadminsrvctl.sh status
$ adnodemgrctl.sh status
3. Run these in order:
$ adop phase=abort
$ adop phase=cleanup cleanup_mode=full
$ adop phase=fs_clone force=yes
4. If any adop phase fails, please generate a new diagnostic info tar.
Diagnostic script to collect information required for AD/TXK 12.2.x bugs ( Doc ID 1901242.1 ).
Hopefully, this one will collect the many queries needed.

AD Administration error:.

ERROR:  Patching cycle in progress - run this utility from patch file          system.

You can only run it from run file system when not patching.


Check the any active adop cycle by running the script ADZDSHOWED.sql:




SQL> @ADZDSHOWED.sql
=========================================================================
= Editions
=========================================================================

Edition Name Type Status Current?
--------------- -------- -------- --------
EDITION1 PATCH ACTIVE
ORA$BASE ACTIVE
V_20000001_2001 ACTIVE



Solution:-


To resolve the issue test the following steps in a development/test instance and then migrate accordingly:

1. Complete or abort any open patching cycles using adop phase=abort.

2. Any remaining database editions (for example 'EDITION1') will need      to be addressed by the DBA.

3. Run ADZDSHOWED.sql to confirm the editions are corrected.


4. Run adadmin and and confirm it proceeds without error.
