The JDBC subject source has queries to search by ID, identifier, and freeform.  The JDBC2 subject source, has a table or view with those columns, and constructs the queries for you.  If possible you should use the JDBC2 subject source.  The JDBC source has issues with pooling if you have a less than reliable network.

Ideally you would create a table or materialized view and migrate data there, and build the JDBC2 subject source.  This will have the best performance. 

Here are some sample columns you need:

If you cannot load data into a table or materialized view, then you should make a view of the data and build the JDBC2 subject source from that view.  Note, if you have a flattened table already (no concatenations, joins, etc), then a view is fine to use (table would not be faster)

If you cannot do either of those, you can make a query that will be used as a table

For instance, here is a table of users (example from florida)

CREATE TABLE ARP_PERSON_INFO
(
  ARP_PAR_UFID               VARCHAR2(8 CHAR)   NOT NULL,

######## SUBJECT ATTRIBUTES ########

Subject id: 'mchyzer@ufl.edu' with subject.getId()
  - the subject id should be an unchanging opaque identifier
  - the subject id is stored in the grouper_members table
Subject name: 'Chris Michael Hyzer' with subject.getName()
  - the subject name is generally first last
Subject description: 'Chris Michael Hyzer, mchyzer@ufl.edu, S, ISC, mchyzer@isc.upenn.edu' with subject.getDescription()
  - the subject description can have more info such as the id, name, dept, etc
Subject type: 'person' with subject.getTypeName()
  - the subject type is not really used
Subject attribute 'email' has 1 value: 'mchyzer@isc.upenn.edu'
  - with subject.getAttributeValue("email")
Subject attribute 'netid' has 1 value: 'mchyzer'
  - with subject.getAttributeValue("netid")
SUCCESS: The emailAttributeName is configured to be: 'email'
SUCCESS: The email address 'mchyzer@isc.upenn.edu' was found and has a valid format

######## SUBJECT IN UI ########

Short link with icon:  Chris Michael Hyzer
  - This is configured in grouper.text.en.us.base.properties with guiSubjectShortLink
  - Also configured in grouper-ui.properties with grouperUi.screenLabel2.sourceId.X
  - By default this is the name of the subject with a tooltip for description
Long label with icon:   Chris Michael Hyzer, mchyzer@ufl.edu, S, ISC, mchyzer@isc.upenn.edu
  - This is not used in the new UI
  - It is configured in grouper-ui.properties with grouperUi.subjectImg.screenEl.
  - By default this is the description of the subject

######## SUBJECT IN WS ########

Look in grouper-ws.properties to see how the WS uses subjects.  This is the default configuation:

# subject attribute names to send back when a WsSubjectResult is sent, comma separated
# e.g. name, netid
# default is none
ws.subject.result.attribute.names = 

# subject result attribute names when extended data is requested (comma separated)
# default is name, description
# note, these will be in addition to ws.subject.result.attribute.names
ws.subject.result.detail.attribute.names =
