Serializable String size limits

I have an remote EJB deployed on WebSphere Application Server 5.1.
The EJB client is invoking this EJB passing it as large string as the input parameter. The size of the string can be upto 20 MB.
The question is - what is the size limit of a serialized object ( in this case String) which can be used during a rmi/iiop invocation?

String size limitations, HTML table

Post Author: Jeff Kulbeth
CA Forum: General
I am currently using CR 8.5 and am aware of string size limitations... 254 characters max. I'm looking at CR XI and can't find any data on string size limitations. A few questions:
1) We're considering database fields larger than 254 characters, and would like to use CR to parse the field. In CR XI, what's the maximum string length that can return from a table and still be used in a formula? Can a Memo field be used in a formula in CR XI?
2) Once I've parsed the fields in the database table, I'll need to return formatted strings back to the report. The strings will be larger than 254 character ... What's the maximum string size allowed in CR XI?
3) Somewhat related, but not entirely: Have any patches been released that provide HTML table interpretation in CR XI?
Thanks for the help,
Jeff Kulbeth

The maximum length of a String constant, a String value held by a String variable, a String value returned by a function or a String element of a String array is 65,534 characters.
The maximum size of an array is 1000 elements.
The maximum number of arguments to a function is 1000. (This applies to functions that can have an indefinite number of arguments such as Choose).
Not sure about the HTML ?

JDBC:KPRB string size limits-NEED HELP!

Hello All.
Please, I need your help.
I have the problems in Oracle 9.2.0.6 with stored java and jdbc:kprb internal driver.
I try to put string(more than 32K) into LONG-type field using following java class:
import oracle.sql.CLOB;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.io.Reader;
import java.io.CharArrayReader;
public class LongTest {
public static void insertLong()
throws Exception {
Connection con = DriverManager.getConnection("jdbc:default:connection:");
//generate large string
StringBuffer stringBuffer = new StringBuffer();
for (int i = 0; i < 100000; i++) {
stringBuffer.append("qwerty");
String st = stringBuffer.toString();
//put large string to long-type field
PreparedStatement pst = null;
try {
pst = con.prepareStatement("insert into TEST_LONG (ldata) values (?)");
pst.setString(1, st);
pst.execute();
} finally {
if (pst != null) {pst.close();}
But I get error from jdbc:kprb about limitation of data size for this type(LONG).
But it works well in oracle 10.2.0.1...
Has anybody a solution of how to do this in oracle 9.2.0.6???
thanx!

Size of connect string

Is there any limit on the length of the connect string?
Thanks
Fiaz

Hi Sarvani
Database Name: select name from v$database . Although you need select privs on the dictionary. select global_name from global_name may or may not give you what you're after. If you substring up to the first "." it should be right. Can't think of any other way.
Connect string: This is a client issue. From the database we can't know that. We can find the SID from v$instance or the registered service names using select value from v$parameter where name = 'service_names' but again you'll need select privs. You also need the listener port and there is not way of finding it from inside the DB. select local_listener from v$parameter will tell you your local listener but you'd have to query the listener (lsnrctl status) to find it's listen port. If you want to get really adventerous you could guess at it. select hostname,instance_name from v$instance and guess at 1521 or 1522 for the port. This won't work well for RAC.
Size: Schema size or application size?

Powershell use Connection String to query Database and write to Excel

Right now I have a powershell script that uses ODBC to query SQL Server 2008 / 2012 database and write to EXCEL
$excel = New-Object -Com Excel.Application
$excel.Visible = $True
$wb = $Excel.Workbooks.Add()
$ws = $wb.Worksheets.Item(1)
$ws.name = "GUP Download Activity"
$qt = $ws.QueryTables.Add("ODBC;DSN=$DSN;UID=$username;PWD=$password", $ws.Range("A1"), $SQL_Statement)
if ($qt.Refresh()){
$ws.Activate()
$ws.Select()
$excel.Rows.Item(1).HorizontalAlignment = $xlCenter
$excel.Rows.Item(1).VerticalAlignment = $xlTop
$excel.Rows.Item("1:1").Font.Name = "Calibri"
$excel.Rows.Item("1:1").Font.Size = 11
$excel.Rows.Item("1:1").Font.Bold = $true
$filename = "D:\Script\Reports\Status_$a.xlsx"
if (test-path $filename ) { rm $filename }
$wb.SaveAs($filename, $xlOpenXMLWorkbook) #save as an XML Workbook (xslx)
$wb.Saved = $True #flag it as being saved
$wb.Close() #close the document
$Excel.Quit() #and the instance of Excel
$wb = $Null #set all variables that point to Excel objects to null
$ws = $Null #makes sure Excel deflates
$Excel=$Null #let the air out
I would like to use connection string to query the database and write results to EXCEL, i.e.
$SQL_Statement = "SELECT ..."
$conn = New-Object System.Data.SqlClient.SqlConnection
$conn.ConnectionString = "Server=10.10.10.10;Initial Catalog=mydatabase;User Id=$username;Password=$password;"
$conn.Open()
$cmd = New-Object System.Data.SqlClient.SqlCommand($SQL_Statement,$conn)
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output += ,@($rdr.GetValue(0), $rdr.GetValue(1))
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
How would I read the columns and data for $sql_output into an EXCEL worksheet. Where do I find these tutorials?

Hi Q.P.Waverly,
If you mean to export the data in $sql_output to excel document, please try to format the output with psobject:
$sql_output=@()
do{
try{
$rdr = $cmd.ExecuteReader()
while ($rdr.read()){
$sql_output+=New-Object PSObject -Property @{data1 = $rdr.GetValue(0);data2 =$rdr.GetValue(1)}
$transactionComplete = $true
catch{
$transactionComplete = $false
}until ($transactionComplete)
$conn.Close()
Then please try to use the cmdlet "Export-Csv" to export the data to excel like:
$sql_output | Export-Csv d:\data.csv
Or you can export to worksheet like:
$excel = New-Object -ComObject Excel.Application
$excel.Visible = $true
$workbook = $excel.Workbooks.Add()
$sheet = $workbook.ActiveSheet
$counter = 0
$sql_output | ForEach-Object {
$counter++
$sheet.cells.Item($counter,1) = $_.data1$sheet.cells.Item($counter,2) = $_.data2}
Refer to:
PowerShell and Excel: Fast, Safe, and Reliable
If there is anything else regarding this issue, please feel free to post back.

Hi,
I have copied a number of SSID packages from a live server to my test server and am trying to get them up and running but I have a problem with the connection. The only thing that is different is the server name. I decided to keep the same connection in the connection manager as it is referenced in a dtsConfig file. I changed the dtsConfig file to reference the new servername [Data Source= new test server name]. I also check my paths and they are pointing to the correct config locations etc.
I found this post which was similar to my problem but I still get problems with the connection
http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1319961&SiteID=1
I updated the connection by changing the server name in the actual connection. I did this from the data flow tab in the Connection Managers sections (MS Visual Studio). Right clicked - Edit - changed the name of the server name to my test server and selected the database. Test connection was fine, and saved this.
Once I saved this, the connection string changed to my current test server in the properties of the connection. However when I run the package I get the following error:
Error: 0xC0202009 at ReportsImport, Connection manager "myconnectionstring": SSIS Error Code DTS_E_OLEDBERROR.  An OLE DB error has occurred. Error code: 0x80004005.

Error: 0xC0024107 at Myprocess import from file: There were errors during task validation.
So even if I change the existing connection properties and save and Build my package again, my connection properties (connectionstring, servername etc) all revert back to its original data source when I re-open the package. Simply it does not seem to be saving the connection properties i put in.
What am I doing wrong or how can I change the existing connection manager to look at the new server. The database is the same and I have full admin privilege on the server.
I don't want to recreate my packages as there are alot and they are not simple.
After changing the connection properties, saving and reloading I get a connection error. But this is because it is not retaining the new connection manger setting i entered.
Incidentally - I created a new SSID to perform a simple connection and write to the the server and it was OK so there is no problem with actually seeing the my test server.
Thanks in advance

Yes, the package is in visual studio and I have executed it. There are no errors but in the output i have the error message about my connection. My dtsConfig file is added to the project in the 'Package Configuration Organizer' and path and files are correct. This is the output error:
Error: 0xC020801C at xx import from file, xxReportsImport [79]: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "myconnectionname" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.
I will try and run it using dtexec.exe. if I have two config files do i use
dtsexec.exe /f <packagename> /conf <configfile> /conf <secondconfigfile>

Nio ByteBuffer and memory-mapped file size limitation

I have a question/issue regarding ByteBuffer and memory-mapped file size limitations. I recently started using NIO FileChannels and ByteBuffers to store and process buffers of binary data. Until now, the maximum individual ByteBuffer/memory-mapped file size I have needed to process was around 80MB.
However, I need to now begin processing larger buffers of binary data from a new source. Initial testing with buffer sizes above 100MB result in IOExceptions (java.lang.OutOfMemoryError: Map failed).
I am using 32bit Windows XP; 2GB of memory (typically 1.3 to 1.5GB free); Java version 1.6.0_03; with -Xmx set to 1280m. Decreasing the Java heap max size down 768m does result in the ability to memory map larger buffers to files, but never bigger than roughly 500MB. However, the application that uses this code contains other components that require the -xMx option to be set to 1280.
The following simple code segment executed by itself will produce the IOException for me when executed using -Xmx1280m. If I use -Xmx768m, I can increase the buffer size up to around 300MB, but never to a size that I would think I could map.
try
String mapFile = "C:/temp/" + UUID.randomUUID().toString() + ".tmp";
FileChannel rwChan = new RandomAccessFile( mapFile, "rw").getChannel();
ByteBuffer byteBuffer = rwChan.map( FileChannel.MapMode.READ_WRITE,
0, 100000000 );
rwChan.close();
catch( Exception e )
e.printStackTrace();
I am hoping that someone can shed some light on the factors that affect the amount of data that may be memory mapped to/in a file at one time. I have investigated this for some time now and based on my understanding of how memory mapped files are supposed to work, I would think that I could map ByteBuffers to files larger than 500MB. I believe that address space plays a role, but I admittedly am no OS address space expert.
Thanks in advance for any input.

How to set ApplicationIntent=ReadOnly in Connection String for SharePoint 2013

SharePoint 2013 and SQL Server 2012 allows us some additional options to create HA and DR sites through AlwaysOn Availablibity Groups and Listeners. Problem that I'm having is that I have a DR site that is at a different location. Microsoft
recommends not to stretch the farm across different locations, so I've created a separate farm for DR. I have my content database in an Availability Group so that is Asynchronously commits data changes across the 2 locations. My DR site
connects to the content database through a Listener.
Since the DR site is connecting to the content database through the Listener, it is connecting the primary replica. In order to connect to the Read Only secondary replica, I need to add "ApplicationIntent=ReadOnly"
to the connection string. How do you do that?

It supports a secondary being Readable, that is all it is telling you. It does not support, nor implement, Read-Intent. This is expected behavior. You can look at the Conn Strings via PowerShell, of course:
$db = get-spdatabase | where {$_.TypeName -like "*Config*"}
$db.DatabaseConnectionString
Data Source=SPSQL;Initial Catalog=Config;Integrated Security=True;Enlist=False;
Pooling=True;Min Pool Size=0;Max Pool Size=100;Connect Timeout=15

Hiding password on the connection string

Hi,
Am trying to see if it is possible to hide password on the connection string when connecting from the application server. I can see one way of doing this, that is to use Oracle's OS Authentication. But because my Oracle is installed on Unix and my application server is on Windows 2000. I am not sure if this is possible?
Has any done something similar before?
Thanks

The problem with using a single sign-in product like Kerberos is I believe the Advanced Security Option is required. The ASO is an additional license fee.
Having the password in a file does not have to be a major security problem. Have a set of common logon modules created, one for each language in use, and have the module contain the logic to fetch the key.
This way the file name and path to the key is not obvious. Then have the premissions set so that only the ID that runs the production batch can read the file. Neither the customers or the developers should have access to that ID.
Unfortunately while this works for works batch ran out of products like Unicenter and application server based applications this technique does not work very well for cleint server applications. Client server based applications really need every user to have to sign-in with their own id.
If every user does not have their own id and it is undesirable to hard code the userid/password into the application then you are back to getting the password from an unsecured external source. Having the common module to do the fetching at least makes someone work to find the ID/password. Any Id used in this manner should have limited access in the database which means you might have two, three, or more such ID's setup but with each having access to the tables behind only specific applications.

ISQL*PLUS dynamic reports - how to pass connect string in the URL

When we run dynamic reports thru ISQL*PLUS, does anyone know how
to pass the connect string info in the URL
The following is the code from ISQL*PLUS users guide but it
dosen't show how to pass the connect string
when I tried to pass hr/your_secret_password@dbserver for userid
I got an error msg

<HTML>
<HEAD>

Thanks
Jay

The form you use should work when your change
"hr/your_secret_password" to a valid username, password
and connect identifier like "hr/hr@MYDB". Don't forget to
configure MYDB in your tnsnames.ora file on the machine that has
the iSQL*Plus server.
What was the error you got?
The full URL syntax did seem to go missing from the 9.0.1 doc.
See below for the full syntax. This should be appearing in a
forthcoming FAQ.
- CJ
What syntax can I use to run an iSQL*Plus Dynamic Report?
You can run a dynamic report by entering the report URI in the
location field of your browser, or by making the report server a
link or the action for an HTML form. The iSQL*Plus 9i Release 1
documentation has examples of these.
The general syntax for running a dynamic report is:
{uri}?[userid=logon&]script=location[&param...]
where uri
Represents the Uniform Resource Identifier (URI)
of the iSQL*Plus Server, for example:
http://host.domain/isqlplus
where logon
Represents the log in to the database to which you
want to connect:
{username[/password][@connect_identifier]}
where location
Represents the URI of the script you want to run.
The syntax is:
http://[host.domain/script_name]
The host serving the script does not have to be
the same as the machine running the iSQL*Plus server.
where param
Specifies the named parameters for the script you
want to run.
Named parameters consist of varname=value pairs.
iSQL*Plus will define the variable varname to equal value prior
to executing the script e.g.
...script=http://server/s1.sql&var1=hello&var2=world
This is equivalent to the SQL*Plus commands:
SQL> define var1=hello
SQL> define var2=world
SQL> @http://server/s1.sql
iSQL*Plus, SQL*Plus and SQL keywords are reserved
and must not be used as the variable names (varname). Note also,
that since variables are delimited by the ampersand character,
there is no requirement to enclose space delimited values with
quotes. However, to embed the ampersand character itself in the
value, it will be necessary to use quotes.
For compatibility with older scripts using the &1
variable syntax, varname may be replaced with the equivalent
variable position as in:
...script=http://server/s1.sql&1=hello&2=world
Note the & is the URL parameter separator and not
related to the script's substitution variable syntax.
Commands and script parameters may be given in any
order in the dynamic report URI. However, please note that if any
parameters begin with reserved keywords such as "script" or
"userid" then it may be interpreted as a command rather than a
literal parameter.

HTML Editor size limitation?

Hi,<br>
I'm using Apex 3.1 on Oracle 10g...<br>
Is there a size limitation on the number of characters in the HTML Editor? <br>
We have a Report/Form combo for a column. clicking on the "Edit" Link from the Report takes you to the Form where you can edit it. <br>
The corresponding database column is of type LONG. I see the data in the report, but clicking on Edit gives me an error - <br>
ORA-20001: Error fetching column value: ORA-06502: PL/SQL: numeric or value error: character string buffer too small <br>
I've tried switching from CLOB to LONG for the column's datatype, but both fail to open the Form. <br>
If I change the Item type to "Text Area", the LONG column works, but I do need it as an HTML Editor... <br>
Thanks for any help!

Maximum string size???

Hello everybody,
I need to know how much data can be stored in a String.
In the following Topic I've read that the String size is limited to 32677 bytes: http://forum.java.sun.com/thread.jsp?forum=31&thread=57885
In another forum I read that String itself has no size-limitation but the amount of data that can be stored is related to the VM HEAP SIZE.
I'd be very glad to receice any help from you.
THX...
Benjamin Gutmann

However looking through the source of String there is
no limit opposed onto the length.Actually there is a limit, because the String data is stored internally in an array of characters. And there is an upper bound on the size of an array, because as the Java language specification says "Arrays must be indexed by int values". That's where Integer.MAX_VALUE comes from.

XMLType field Size Limitation

Hi,
I am using Oracle DB 9.2.0 version and Toplink 9.0.3 version.
Tables in the database have some fields defined as XMLType and i am using toplink's mapping to insert values in those fields. (Note: This was not directly possible but there was a patch provided by oracle which made this work). The mapped object's xmltype variable is defined as String.
Now I wanted to know if there is any size limitations on the XML content to be inserted in the database XMLType field. If so please do let me know exact size.
Thanks,

Good afternoon,
The folks on the Oracle XDB forum might be able to better answer your question.
