JDBC to file scenario - Time limit exceeded

Question

Hi All,
I am getting timelimit exceeded error in the inbound queues when I am processing the interface JDBC-XI-file. I have tried many options like registering the queues, changed the integration engine configuraion parameters for timeout , checked the memory space. When less data is being sent like 50kb then it is executing successfully. With large data the messages are getting stuck in the queues and then giving the timeout error.
Also when I  am checking in sm50 it showing that some rfc is going on hold.
Please suggest .
Thanks,
Aparna

Thanks for the reply Pragati.
What will be the UDF code for RFC lookup in case of passing the data in Queue. I am currently using the below code for gettng single value.
Also is it possible to get multiple output values which can be mapped to different target fields. Currently I am using different rfc lookups for different target fields. So if I can combine them into single rfc lookup them this may effect the performance.
   //write your code here
String content = "";
MappingTrace importanttrace;
importanttrace = container.getTrace();
// Create document builder to create DOM XML document
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = null;
factory.setNamespaceAware(false);
factory.setValidating(false);
try {
        // Create XML document using document builder
        builder = factory.newDocumentBuilder();
} catch (Exception e) {
       importanttrace.addWarning("Error creating DocumentBuilder - " + e.getMessage());
        return null;
// filling the string with our RFC-XML (with values)
String m ="<?xml version=\"1.0\" encoding=\"UTF-8\"?><ns1:ZFI_GET_COCODE xmlns:ns1=\"urn:sap-com:document:sap:rfc:functions\"><COMPANYID>" + a + "</COMPANYID></ns1:ZFI_GET_COCODE>";
RfcAccessor accessor = null;
ByteArrayOutputStream out = null;
Payload result = null;
try
// 1. Determine a channel (Business system, Communication channel)
Channel channel = LookupService.getChannel("BS_SAP_DEC210","CC_RECEIVER_RFC_test");
// 2. Get a RFC accessor for a channel.
accessor = LookupService.getRfcAccessor(channel);
// 3. Create a xml input stream representing the function module request message.
InputStream inputStream = new ByteArrayInputStream(m.getBytes());
// 4. Create xml payload
XmlPayload payload = LookupService.getXmlPayload(inputStream);
// 5. Execute lookup
result = accessor.call(payload);
/*InputStream in = result.getContent();
out = new ByteArrayOutputStream(1024);
byte[] buffer = new byte[1024];
for (int read = in.read(buffer); read > 0; read = in.read(buffer)) {
out.write(buffer, 0, read);
content = out.toString();
if (result == null) {
                importanttrace.addWarning("result of RFC call is null");
catch(LookupException e)
importanttrace.addWarning("Error while lookup " + e.getMessage() );
Document docResponse = null;
InputStream in = result.getContent();
String res = "";
try {
        docResponse = builder.parse(in);
        if (docResponse == null) {
                importanttrace.addWarning("docResponse is null");
res =  docResponse.getElementsByTagName("COMPANY_CODE").item(0).getFirstChild().getNodeValue();
if (res == null) {
                importanttrace.addWarning("res is null");
catch (Exception e) {
      importanttrace.addWarning("Error when parsing RFC Response - " + e.getMessage());
try {
        // Free resources, close the accessor..
        if (accessor != null) {
                try {
                        accessor.close();
                } catch (LookupException e) {
                        importanttrace.addWarning( "Error while closing accessor " + e.getMessage());
} catch (Exception e) {
        importanttrace.addWarning("Result value not found in DOM - " + e);
// return the result obtained above
return res;
Thanks.
