What is apps listener and why it used?

Apps listener is combination of FNDFS&FNDSM it’s running all apps node with listener alias name. It’s mainly used for listening the request for services like FNDFS&FNDSM

What is difference between Socket & Servlet Mode in Apps Forms?

When forms run SOCKET Mode these are dedicated connection between Client Machine & Form Server (Started by adfrmctl.sh).

When Forms run in servlet mode the forms requests are fulfilled by Jserv in Apache . There will be additional JVM for Forms Request in that case and you won't start form via adfrmctl.sh.

What is batch size in adpatch?

Batch size is how many table performed same time. If example I give batch size 1000 means 1000 tables will perform same time in patching activity.

What is (.lgi) file ?

Lgi files are created with patching along with patch log file (.log) it’s contain information related to patch

Patch will create two tables what are the content of the tables?

Fnd_install_processes and ad_differed_jobs will create during patching cycle. Both are temporary table.
Fnd_install_processes:
This table will store the worker information like what job assigned to which worker and it’s status.
ad_differed_jobs:
This table is used to store the information about failed worker job

Explin Concurrent Request Life Cycle?

Pending / Normal
This request is waiting for next available concurrent manager
Increase number “processes” of the Concurrent Manager

Pending / Standby
The Request is waiting at CRM due to Conflict Request which is already being run.

Running / Normal
This Request is running normal if If the request is taking longer time, enable Database Trace and tkprof and find out expensive DML

Completed / Error
Check the request log file and take action accordingly

Inactive / No Manager
Manager is not available that manager

Explain concurrent manager tables?

Fnd_concurrent_requests
Fnd_concurrent_programs
Fnd_concurrent_process
Fnd_concurrent_queues

What is AutoConfig?

AutoConfig is a configuration tool that automates the configuration of an Oracle E-Business Suite instance. The information required for configuring an Applications system is collected into an XML repository, called the Applications context file

If we run autoconfig which file will get effect how to find?

If we want to check we can run adchkcfg utlity it will generate HTML report will list of files and profile options  going to change the autoconfig
Adchkcfg.sh location:cd $AD_TOP/bin

How can I roll back an AutoConfig session?

All backup configuration files from each AutoConfig session are stored in:
On the application tier:
<INST_TOP>/admin/out/<MMDDhhmm>
On the database tier:
<RDBMS ORACLE_HOME>/appsutil/out/<CONTEXT_NAME>/<MMDDhhmm>
where: <MMDDhhmm> = (month, day, hour, and minute of the AutoConfig run)
You can run restore.sh (UNIX) or restore.cmd (Windows) to roll back an AutoConfig session.

Collect below basis level of information to development team 1 Oracle seeded program/Custom program? 2 How much time it used earlier? 3 Is there any recent code change done in concurrent program? 4 Is this program fetching higher data compare to last run? 5 Does this job running any specific time/ It can be run any time? 6 Does this job fetching data using DB link? 7 Does the problem happen on both the test and production instance? Once asked above questions to development team in meanwhile we need to start basic sanity check in our environment. 1 Verify the status of the concurrent program select REQUEST_ID,phase_code,status_code,ORACLE_SESSION_ID from apps.fnd_concurrent_requests where request_id=’1234567’; 2 Find which concurrent manger ran a specific concurrent request select b.USER_CONCURR
