Number of processes capacity for the Datasource "EBSDatasource" is exhausted.

Solution:

1. Increase the number of sessions in EBSDatasource

Login to weblogic Console, Navigate to Datasource, click on EBSDatasource.

Click on Lock and Edit, Go to Connection Pool Tab, Increase the value in Number of sessions field.

Click on Activate Changes.


This change does not require any restart of services.


(or)

Alternate Solution:

2. Bounce oacore_server to release any inactive sessions and free up the resources

cd $ADMIN_SCRIPTS_HOME

admanagedsrvctl.sh stop oacore_server

admanagedsrvctl.sh start oacore_server

Query to check installed modules in Oracle EBS

The below query query gives the list of Installed/Not Installed/Shared Product Modules in Oracle E-Business Suite (EBS) application



set pages 20000;
col application_id for 9999;
col application_name for A50;
col status for A1;
col application_short_name for A10;
select fa.application_id,
fa.application_short_name,
fpi.status,
fatl.application_name
from
fnd_product_installations fpi,
fnd_application fa,
fnd_application_tl fatl
where
(
fa.application_id = fpi.application_id and
fa.application_id = fatl.application_id and
fatl.language = 'US'
)
order by fa.application_short_name;


Check for values in Status column of the output, usually either I or N or S.

I - Installed
S - Shared
N - Not Licensed
