There are some tables in oracle apps (AD tables especially) involved when applying patches.

Some of them are very useful when we need specific information about patch already applied.I will show the main tables and afterwards some handy related SQL’s to retrieve patch applied details and how we can also get all this information via OAM.AD_APPLIED_PATCHES – The main table when we are talking about patches that applied in Oracle Apps.This table holds information about the "distinct" Oracle Applications patches that have been applied.If 2 patches happen to have the same name but are different in content (e.g. "merged" patches), then they are considered distinct and this table will therefore hold 2 records (eTRM).I also found that if the applications tier node is separate from the concurrent manager node, and the patch applied on both nodes, this table will hold 2 records, one for each node.AD_PATCH_DRIVERS – This table holds information about all patch drivers included in specific patch.For example if patch contain only one unified driver like u[patch_name].drv then ad_patch_drivers will hold 1 record.On the other hand, if patch contain more than 1 driver, for example d[patch_name].drv and c[patch_name].drv, this table will hold 2 records.AD_PATCH_RUNS – holds information about each execution of adpatch for a specific patch driver.In case a patch contains more than one driver, this table will hold a record for each driver.This table also holds one record for each node the patch driver has been applied on (column APPL_TOP_ID).AD_PATCH_RUN_BUGS – holds information about all the bugs fixed as a part of specific run of adpatch.AD_BUGS – this table holds information about all bug fixes that have been applied.We have 2 options to view applied patch information:

1) via OAM – Oracle Applications Manager2) Via SQL queriesWith OAM it’s easy and very intuitive, from OAM site map -> “Maintenance” tab -> “Applied Patches” under Patching and Utilities.Search by Patch ID will get all information about this patch; In addition, drill down by clicking on details will show the driver details.For each driver we can use the buttons (Timing Details, Files Copied, etc.) to get more detailed information.With SQL we can retrieve all the above information, sometimes more easily.

For example: How to know which modules affected by specific patch?

With OAM:1) search patch by Patch ID2) click on Details3) For each driver click on “Bug Fixes” and look on product column.With SQL:Run the following query, it will show you all modules affected by specific patch in one click…select distinct aprb.application_short_name as "Affected Modules"

from ad_applied_patches aap,

ad_patch_drivers apd,

ad_patch_runs apr,

ad_patch_run_bugs aprb

where aap.applied_patch_id = apd.applied_patch_id

and apd.patch_driver_id = apr.patch_driver_id

and apr.patch_run_id = aprb.patch_run_id

and aprb.applied_flag = 'Y'

and aap.patch_name = '&PatchName';

Another SQL will retrieve basic information regarding patch applied, useful when you need to know when and where (node) you applied specific patch:select aap.patch_name, aat.name, apr.end_date

from ad_applied_patches aap,

ad_patch_drivers apd,

ad_patch_runs apr,

ad_appl_tops aat

where aap.applied_patch_id = apd.applied_patch_id

and apd.patch_driver_id = apr.patch_driver_id

and aat.appl_top_id = apr.appl_top_id

and aap.patch_name = '&PatchName';

To check if specific bug fix is applied, you need to query the AD_BUGS table only.This table contains all patches and all superseded patches ever applied:select ab.bug_number, ab.creation_date

from ad_bugs ab

where ab.bug_number = '&BugNumber';

For any question or additional information you are welcome to leave a comment...
