EBS 12.2.X Patching: ADOP Cutover failed while running


 During an adop online patching cycle, cutover phase failed while running the script

  [PROCEDURE]  Starting Middle Tier Services
    [UNEXPECTED]Error occurred running "perl /test/app/fs1/EBSapps/appl/ad/12.0.0/patch/115/bin/ -contextfile=/test/app/fs1/inst/apps/EBSTEST_testebsmt111/appl/admin/EBSTEST_testebsmt111.xml -patchcontextfile=/test/app/fs1/2/inst/apps/EBSTEST_testebsmt111/appl/admin/EBSTEST_testebsmt111.xml -promptmsg=hide -console=off -sessionid=14 -timestamp=20201108_194155 -outdir=/test/app/fs_ne/EBSapps/log/adop/14/20201108_194155/cutover/testebsmt111 -action=forcestartup"
    [UNEXPECTED]Cutover phase has failed.


Review of all adop and cutover log files shows that Cutover phase failed after filesystem switch and ADMIN server startup,oacore services could not be started after cutover due to port conflict.


1. Check Status of adop session using below sql query:
set pagesize 200;
set linesize 160;
col PREPARE_STATUS format a15
col APPLY_STATUS format a15
col CUTOVER_STATUS format a15
col ABORT_STATUS format a15
col STATUS format a15

For my issue, cutover status was 5, which means ADMIN startup is completed.

2. Restart the cutover phase with mtrestart=no option

adop phase=cutover mtrestart=no

3. Fix the issues related to services startup on RUN filesystem (which is switched after cutover).

4. Startup the services

5. Perform cleanup phase and complete the adop cycle

adop phase=cleanup

Troubleshooting concurrent requests struck at Post processing Phase

Sometimes , Eventhough the Database sessions related to the concurrent Programs are in INACTIVE State , we could not terminate the Concurrent Request with error "Could not Lock Request" , Issue could be Requests are struck at Post Processing Phase and OutPut Post Processor is locking the Concurrent Requests.

Need to follow the below steps to perform clean shutdown of Oracle Concurrent Manager.

a) Put Pending Concurrent Requests on hold using the below sql queries.

+Create table apps.conc_req_on_hold as select * from fnd_Concurrent_requests where PHASE_CODE='P' and hold_flag='N';
+select count(*) from apps.conc_req_on_hold
+ update fnd_Concurrent_requests set hold_flag='Y' where PHASE_CODE='P' and hold_flag='N' and request_id in (select request_id from apps.conc_req_on_hold);

NOTE: You have to commit if select & update are same number of records. Otherwise rollback and try again till the numbers are same

+ Commit;

You can find more details about putting Pending Concurrent Jobs on Hold here.

b)Bring Down Concurrent Manager using stop

c) Update the status of Struck Concurrent Requests to "Terminated" 

SQL> update fnd_concurrent_requests set status_code='X',phase_code='C' where status_code='R' and phase_code='R';


Use Concurrent Manager Recovery Wizard from OAM to clear the database sessions associated with cancelled Requests.

d) Start Concurrent Manager using

e) Remove Hold on Concurrent Requests

SQL>update fnd_Concurrent_requests set hold_flag='N' where request_id in (select request_id from apps.conc_req_on_hold);

Commit the changes


Steps to create Database link from Oracle Database to Microsoft SQLServer Database:

Steps to create Database link from Oracle Database to Microsoft SQLServer Database:


1. Check Network communication is Opened from Oracle Database Server to MSSQL Database Server using telnet
2. Download the Oracle Gateway Server Software same as your Oracle Database version.

Installation of Oracle Gateway Software

Hope you have downloaded the Dg4msql software for sql server 

1> Create a directory as gateway under $ORACLE_BASE directory. 

2) Invoke the GUI , Select Oracle Gateway for MYSQL and enter the sql server details at the time of installation 

3) Before completing the installation, OUI invokes the NETCA and create a new listener for gateway with new port (ex:1526) 

Note; In case if you have defined any bash profile for TNS_ADMIN, then please comment it 

4. Follow the below note for pre-req for gateway listener 

How to Configure DG4MSQL (Oracle Database Gateway for MS SQL Server) 64bit Unix OS (Linux, Solaris, AIX,HP-UX) post install ( Doc ID 562509.1 ) 

edit your gateway listener as recommended in the above note. 

5. create a tnsentry in $ORACLE_HOME/network/admin 

6. export TNS_ADMIN=$gateway home/network/admin 

lsnrctl stop <gateway listener> 

lsnrctl start <gateway listener> 

tnsping <gateway alias>

Concurrent Manager Troubleshooting : Multiple Concurrent Requests Struck without Processing

Scenario: Concurrent Requests are in Running Normal state for longer time than normal duration of the Program.


Step 1: Navigate to System Administrator Responsibility : Concurrent Manager --> Administer

Identify the Concurrent Requests which are in Running Status.

Get the Database Session Details of the currently running concurrent requests using the below Query:

SELECT DISTINCT  a.request_id,C.INST_ID, d.sid, d.serial# ,d.osuser,d.process , c.SPID ,d.inst_id
FROM apps.fnd_concurrent_requests a,
apps.fnd_concurrent_processes b,
gv$process c,
gv$session d
WHERE a.controlling_manager = b.concurrent_process_id
AND = b.oracle_process_id
AND b.session_id=d.audsid
AND a.phase_code = 'R' and a.status_coDe='R';

Step 2: Verify if the database sessions are active/Inactive at the database level using the below query.

select inst_id,sid,serial#,program,module,status,last_call_et,sql_id from gv$session where sid=&sid;

-- sid value to be taken from output of Sql Query in Step 1

If Database session is INACTIVE And Running no sql for more than an Hour, we can Terminate the Concurrent Requests.
If the Database session is ACTIVE and has an SQL_ID attached with it, Need to check on tuning the sql being run by the database session.

I will cover more details about SQL Tuning in another post.

How to use coe_xfr_sql_profile.sql to Improve performance of a sql query?

Oracle SQL Performance tuning is one of the frequently reported issues in a Oracle Database administrator's daily job.
Very often we notice that sql queries or concurrent Programs which were running within few minutes earlier are now taking hours to be completed.
Underlying reason is due to the plan_hash_value used by the query has been changed.
coe_xfr_sql_profile.sql is the script developed by Oracle Support which helps us to identify the plan_hash_value which will resolve the performance issue.

Steps to use the script coe_xfr_sql_profile.sql

1. Download the script to a temporary directory on the database server.
Script is also available in Oracle Metalink.

2. Before Running the coe_xfr_sql_profile.sql, we need to know the sql_id of the sql query which is taking longer time to complete than usual.

To find the sql_id use below query

2.1 If you know the database SID of the long running query.
select inst_id,sid,serial#,status,last_Call_et,sql_id from gv$session where sid= '&sessionid';

2.2 If you know the query test, Use gv$sql and gv$sqlarea views to get the sql_id.

3. Login to sqlplus as sysdba and run coe_xfr_sql_profile.sql at the SQL prompt.

$ sqlplus “/as sysdba”
SQL> @coe_xfr_sql_profile.sql
Parameter 1:
SQL_ID (required)

Enter value for 1: 0a3f7vuks8d7y   (--this is the sql_id of long running sql)
————— ———–
1484137450 15.6
3622468234 4560.76

[Output shows the list of available plan hash values, which can be forced on to the sql query. We need to select the plan_hash_value with low ETA to resolve the performance issue]

Parameter 2:
PLAN_HASH_VALUE (required)

Enter value for 2: 1484137450 

++Based on the inputs provided, it generates a sql script with naming convention coe_xfr_sql_profile_0a3f7vuks8d7y_1484137450.sql as output


4. Run the script as sysdba


5. Verify that Performance issue is resolved by Re-running the sql.
