What table stores incoming XML message

Question

Hi Gurus,
Can anyone tell me which is the table where the XML of incoming messages are stored in integration broker. I am aware of the tables like PSAPMSGSUBCON,etc mainly give only the status and other information about the message; but I am interested in knowing where exactly is the actual XML stored in the database.

OK. I did some testing with the data in PSAPMSGPUBDATA. Base64 is not involved anywhere. I did this against PT 8.50. I think PT 8.48 to PT 8.50 (the current version) would be the same. I looked at some code I wrote for PT 8.45 and it was very similar. The table and fields were different, but the compression, etc was the same.
It appears that the data in the MIMEDATALONG field is compressed only (no base64, etc). I don't know the compression algorithm used. I used the java.util.zip.Inflater class to "inflate" the contents.
About concatenating the "pieces"... I didn't have any large enough messages to see data chunking. From my testing, I saw that SUBSEGMENTNO of 0 contained the JMS header and IBInfo. SUBSEGMENTN0 of 1 had the XML message. It seems that the DATASEQNO field would contain an index for chunked data, but I didn't have any messages large enough to verify. For each SUBSEGMENTNO, I inflated them separately, not concatenated. I don't know if chunked data is zipped and then chunked, or chunked and then zipped. This will determine whether you concatenate data and then inflate or inflate and then concatenate.
Here is my test code:
import java.io.UnsupportedEncodingException;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.zip.DataFormatException;
import java.util.zip.Inflater;
public class MessageDownloader {
  public MessageDownloader() {
    super();
  public static void main(String[] args) throws SQLException,
                                                DataFormatException,
                                                UnsupportedEncodingException {
    Connection conn =
      DriverManager.getConnection("jdbc:oracle:thin:@your.db.server:1521:YOURSID",
                                  "username", "password");
    Statement stmt = conn.createStatement();
    ResultSet rs =
      stmt.executeQuery("SELECT IBTRANSACTIONID, IB_SEGMENTINDEX, SEGMENTNO, SUBSEGMENTNO, UNCOMPMIMEDATALEN, MIMEDATALONG\n" +
        "  FROM PSAPMSGPUBDATA\n" +
        //" WHERE IBTRANSACTIONID = 'GUID-GOES-HERE'\n" +
        " ORDER BY IBTRANSACTIONID, IB_SEGMENTINDEX, SEGMENTNO, SUBSEGMENTNO, DATASEQNO\n");
    String id = "";
    while (rs.next()) {
      if(!id.equals(rs.getString("IBTRANSACTIONID"))) {
        id = rs.getString("IBTRANSACTIONID");
        System.out.println("----------------------------------------------------");
        System.out.println("******  " + id + "  ******");
      String segment = rs.getInt("IB_SEGMENTINDEX") + "-" +
                     rs.getInt("SEGMENTNO") + "-" +
                     rs.getInt("SUBSEGMENTNO");
      Inflater inflater = new Inflater();
      byte[] result = new byte[rs.getInt("UNCOMPMIMEDATALEN")];
      inflater.setInput(rs.getBytes("MIMEDATALONG"));
      int length = inflater.inflate(result);
      System.out.println("Segment: " + segment);
      System.out.println(new String(result, 0, length, "UTF-8"));
      System.out.println();
      System.out.println("--");
      System.out.println();
      inflater.end();
}
