2. What is iAS Patch ?
iAS Patch are patches released to fix bugs associated with IAS_ORACLE_HOME (Web Server Component) Usually these are shipped as Shell scripts & you apply iAS patches by executing Shell script.
3. I am applying a patch , can I open another session and run adadmin ?
Yes, We can run unless you are running a process where workers are involved
4. I am applying a patch , can I open another session in another node and run adpatch?
No because it will create tables while running first session when you start the 2nd session it will fail due to the first

top is a operating system command, it will display top 10 processes which are taking high cpu and memory. 8. What is a patch?Ans : A patch can be a solution for a bug/it can be a new feature.
18. What are the different types of patches?
oneoff, mini packs, family packs, maintanance packs, rollup pathches, colsolidated patches.
19. What is a oneoff patch?
An oneoff patch is a small patch of (20-90K size) without any pre-req’s
20. What is a mini pack ?
A mini pack is one which will upgrade any product patchset level to next level like AD.H to AD.I
21. What is Family pack ?
A Family pack is one which will upgade the patchset level of all the products in that family to perticular patchsetlevel.
22. What is Maintanance pack ?
A maintanance pack will upgrade applications from one version to another like 11.5.8 to 11.5.9
23. What is a Rollup patch?

Consolidated patches will come into pictures after upgrades from one version of applications to anoter, all post upgrade patches will a consolidated and given as consolidated patch.
25. How u will find whether a patch is applied/not?
Query ad_bugs.
26. What is the other table where u can query what are the patches applied?
Ad_applied_patches
27. What is the difference between ad_bugs and ad_applied_patches?
A patch can deliver solution for more than one bug, so ad_applied_patches may not give u the perfect information as in case of ad_bugs.
28. How u apply a patch?
adpatch
29. What inputs you need to apply a patch other than driver name and etc?
apps and system passwords
30. What are the table u r adpatch will create and when?
Adpatch will create FND_INSTALL_PROCESSES and AD_DEFERRED_JOBS table when it will apply d,g and u drivers
31. What is the significance of FND_INSTALL_PROCESSES and AD_DEFERRED_JOBS table?
FND_INSTALL_PROCESSES table will store the worker information like what job is assigned to which worker and its status. AD_DEFERRED_JOBS will come into picture when some worker is failed, it will be moved to AD_DEFERRED_JOBS table, from where again adpatch will take that job and try to resign, after doing this 3 times if still that worker is failing, then adpatch will stop patching and throw the error that perticular worker has failed. We need to trouble shoot and restrart the worker.
32. If it is a multinode installation which driver we need to apply on which node?
c,d,g on concurrent node and c, g on web node. If it is u-driver we need to apply on all nodes.
33. While applying a application patch is that necessary that u r database and listener should be up?
Yes . why because adpatch will connect to database and update so many tables etc…..
34. While applying a patch if that patch is failing because of a pre-req then how you will apply that pre-req patch and resume with the current patch?
We need to take the backup of FND_INSTALL_PROCESSES and AD_DEFERRED_JOBS tables and restart directory at APPL_TOP/amdin/SID and then use adctrl to quit all the workers. Then apply the pre-req patch , after that rename u r restart directory to its original name and create FND_INSTALL_PROCESSES and AD_DEFERRED_JOBS tables from the bcakup tables. Start adpatch session and take the options want to continue previous session.
35. What is adctrl?
Adctrl is one of the adutilities, which is used to check the status of workers and to manage the workers.
36. Can u name some of the menu options in adctrl?
Check the status of workers, tell manager that worker has quited, restart a failed worker etc….
37. How to skip a worker and why?
We can skip a worker using option 8 in adctrl which is hidden. We will go for skipping a worker when we have executed the job which the worker is supposed to do.
38. How adpatch knows what are the pre-req’s for the patch which it is applying?
With every patch a file called b.ldt file will be delivered which contain the pre-req information. adpatch load this into databse using FNDLOAD and check , whether those pre-req patches were applied or not.
39. What is FNDLOAD ?
FNDLOAD is a utility which is similar to sqlloder but loads code objects into database, where as SQLLOADER loads data objects into database.
40. What c-driver will do?
C-drive copies the files from patch unzipped directory to required location in u r application file system. Before copying it will check the file version of the existing file at the file system with the file version of the file in the patch. If the patch file version is higher than what it is at file system level then only c-driver will copy that files.
41. How adpatch will know the file versions of the patch delivered files?
With each patch a file with name f.ldt is delivered , which contain the file versions of the files dilivered with the patch. Adpatch will use this file to compare the file versions of files its delivering with the file on file system.
42. What is the adpatch log file location?
APPL_TOP/admin/SID/log
43. What is the worker log file name and its location?
adwork01,adwork02…… and location is APPL_TOP/admin/SID/log
44. How u will know what are the files the patch is going to change just my unzipping the patch?
When u unzip a patch it will keep all the files related to a particular product under that directory inside u r patch directory for example if the patch delivering files related to FND product then it will create a sub directory under the patch directory with the name FND in which it will put all related files to that product
45. What is the significance of backup directory under u r patch directory?
When we apply a patch it will keep the copy of the files which its going to change in file system.

38. How adpatch knows what are the pre-req’s for the patch which it is applying?
With every patch a file called b.ldt file will be delivered which contain the pre-req information. adpatch load this into databse using FNDLOAD and check , whether those pre-req patches were applied or not.
39. What is FNDLOAD ?
FNDLOAD is a utility which is similar to sqlloder but loads code objects into database, where as SQLLOADER loads data objects into database.
40. What c-driver will do?
C-drive copies the files from patch unzipped directory to required location in u r application file system. Before copying it will check the file version of the existing file at the file system with the file version of the file in the patch. If the patch file version is higher than what it is at file system level then only c-driver will copy that files.
41. How adpatch will know the file versions of the patch delivered files?
With each patch a file with name f.ldt is delivered , which contain the file versions of the files dilivered with the patch. Adpatch will use this file to compare the file versions of files its delivering with the file on file system.
