In WebLogic, we can change the datasource type (e.g., from Generic to GridLink or XA) using the WLST (WebLogic Scripting Tool)

Step 1: Set the environment

export ORACLE_BASE=/Middleware/oracle

export DOMAIN_NAME=uatdomain

export DOMAIN_HOME=$ORACLE_BASE/config/domains/$DOMAIN_NAME
export WL_HOME=/Middleware/oracle/product/fmw/wlserver 

cd $WL_HOME/common/bin 

$ $WL_HOME/common/bin/wlst.sh

connect('weblogic', 'password', 't3://IP:PORP')

Step 2: Update the DataSource

Note: Change Yello highlighted Data Source Name as per your environment

edit()

startEdit()

cd ('/JDBCSystemResources/LocalSvcTblDataSource/JDBCResource/LocalSvcTblDataSource')

set('DatasourceType', 'AGL')

save()

activate()

exit()

3. Restart WebLogic (If Needed)
