Migration of LONG and LONG RAW datatype

Just upgraded a DB from 8.1.7.4 to 10.2.0.1.0. In the post-upgrade tasks, it speaks of migrating tables with LONG and LONG RAW datatypes to CLOB's or BLOB's. All of my tables in the DB with LONG or LONG RAW datatypes are in the sys, sysman, mdsys or system schemas (as per query of dba_tab_columns). Are these to be converted? Or, does Oracle want us to convert user data only (user_tab_columns)?

USER_TAB_COLUMNS tells you the columns in the tables owned by the current user. There may well be many users on your system that you created that contain objects. I suppose you could log in to each of those schemas and query their USER_TAB_COLUMNS table, but it's probably easier to query DBA_TAB_COLUMNS with an appropriate WHERE clause on the owner of the objects.

Word File Takes Longer and Longer to Save

I’ve been working daily on the same 100-page document for several months. I had no problems with the document under Word 2003. However, under Word 2010 the file grows in size over time, and saving the file takes longer and longer to the point where there
are significant timeouts (Word is “not responding”) whenever an automatic save occurs.
I don't want to diable automatic saves because Word does crash for me on rare occasions, generally if I do something "too fast".
I’ve found a workaround for the problem, and every three weeks or so after the automatic saves have become painfully long I copy the document to the clipboard (except for the last paragraph mark) and then I open a new document based on the relevant template
and I paste the clipboard contents into the new document. I rename the old version of the document and the new version becomes the working version. This reduces the file size (currently around 1.4 MB) by about 150 KB and the problem goes away for another three
weeks.
Certain aspects of my situation are unusual, and these may or may not be relevant to the problem:
At the end of each day I use (via a macro) the Review, Compare feature of Word to compare the document with the previous day’s version to allow me to reread any changes I made to it.
I use various other macros for intelligent page-turning, resizing windows, smart Find, etc.
I maintain the document as a DOC file (Word 97-2003 Compatibility Mode) because I need to share the document with an organization that requires this format.
The document flips back and forth a few times between being a one-column and two-column document.
The document has a table of contents on the last page.
The headings in the document have embedded section and subsection numbers.
The document has numerous embedded SEQ and cross-reference fields.
The document has embedded EMF pictures that were generated by a non-Microsoft application.
The long times to save the file and the temporary solution I’ve found to the problem suggest that some "junk" is accumulating “in” the last paragraph mark. This junk doesn't cause any operational errors, but it slows things down to the point where
the auto-save times out and I temporarily get the distracting "not responding" message. It would be nice if Word could automatically eliminate the junk in the last paragraph mark so that I wouldn’t have to do it manually.
Do you have any suggestions for how I might eliminate the problem?
I'd be pleased to send a copy of the slow-saving file to a Microsoft Word programmer for diagnosis of the problem.
I have up-to-date Windows 7 professional (64 bit) and Word 2010 14.0.6129.5000 (32 bit).
Thanks for your help,
Don Macnaughton

I am experiencing exactly the same save issue, although I cannot use the suggestion of copying to a new document as I have allot of references within the same document and I'm scared that I'll loose them (or mess them up).
It is nearly a year later, did you have any luck?
Francois,
I'm still experiencing the problem. However, I've now converted the document from a DOC to a DOCX, but that made no difference. So every 18 or so days I copy all of the document into a new document except for the last paragraph mark
and the problem goes away for another 18 or so days. For my document this solution is fully reliable although it's less convenient because it's a little complicated and I worry I may make a mistake or some text may be lost in the transition.
So I'm still looking for a solution to the problem. Is there anything unique about your document or your handling of the document that might be the cause of the problem? Are you using macros, Compare Versions, switching back and forth between
one and two columns, or anything else that is common to the features that I list in my first post in this thread?
You might want to try my copying solution as a test while keeping your original document as the official version that you continue to work with. You could then check the test document very carefully to see if my solution works with your
document. You might find that you can trust my solution (or you might not).
By the way, I make sure that the copy worked properly by doing a Compare Versions of the old and new documents. (Surprisingly, sometimes the compare finds very minor differences between the two documents, but usually not.)
If the problem really bothers you, you can hire Microsoft Support, although that will cost you some money. If you do that, please let us know the outcome.

Why do contacts name keep getting longer and longer?

On some of my contacts, the name keeps getting longer and longer.
For example, if my name is Jason Kahng.
After a few weeks, when I lookup my name in Contacts it comes up as "Jason Kahng Jason Kahng Jason Kahng"
This is very annoying. If I edit the name back down to Jason Kahng, it will do this again a few weeks later.
Please let me know how to fix this problem.
Thank you!

Your iPhone uses Wi Fi to sync your contacts, not iTunes with iOS 5.0.1
Tap Settings > iCloud
Switch Contacts off then back on then reset the iPhone.
Hold the On/Off Sleep/Wake button and the Home button down at the same time for at least ten seconds, until the Apple logo appears.

3.x Workbooks taking longer and longer to run each week

Hey all, I have a user who has embedded 5 versions of the same query into a workbook. He runs this workbook every monday. When he first created the workbook it took 30 minutes to run. Each week that goes by the workbook takes longer and longer to run and eventually gets to the runtime of 2 hours. Periodically my user has to go and make a change to the workbook and after he recreates the workbook then it goes back to taking 30 minutes to run.
Is there some kind of a buffer that is filling up that I don't know about? Is there a way I can refresh the workbook so that the runtime doesn't creep like it is doing?
Thanks
Adam

Guess I posted prematurely. Looking closer I realized there was a select happening during this process against a text column without an index. The slowdown was just the increasing cost of looping through the the entire dataset looking at strings that often shared a fairly sizable starting substring.

The pinwheel is spinning for longer and longer periods of time. Have to manually shut off iMac sometimes to get it to restart.

The pinwheel is spinning for longer and longer periods of time. Why and what do I need to do about that?

You have 10.6 on that machine, I suggest you stick with it for performance, third party hardware and software reasons as long as possible.
Consider 10.8 (not 10.7) when it's released, because 10.7 and 10.8 will require a new investment in software and newer third party hardware as it requires newer drivers the old machines won't have. (forced upgrade because of software, really nice of them)

Oraclebinary and log raw datatypes

hi
i have a table (oracle XE 10g) with a column LONG RAW data types, the column contains a XML file for XSLT tranformation.
i want read th column and i write this code but it don't works!!!
Private Sub leggiRiparto()
Dim codiceProvincia As String
Dim codiceComune As String
Dim codtipoelezione As String
'query per la lettura dalla tabella outputscrutini del Db elez
Dim strSQL As New String("SELECT o.DATAELEZIONE, o.CODPROVINCIA,o.CODCOMUNE,o.CODTIPOELEZIONE, o.XML, c.DESCCOMUNE " & _
"FROM outputscrutinio o, comune c " & _
"WHERE o.dataElezione = " & dataElezione & " and o.codtipoelezione = " & tipoelezione & _
" AND o.CODPROVINCIA = c.CODPROVINCIA " & _
" AND o.CODCOMUNE = c.CODCOMUNE " & _
"ORDER by o.codprovincia, o.codcomune")
Dim riparti As OracleCommand ' New OracleCommand(strSQL, dbElezioniDDE)
riparti = New OracleCommand(strSQL, dbElezioniDDE)
Try
'ApriDB()
Dim dtRead As OracleDataReader = riparti.ExecuteReader
If Not dtRead.HasRows Then
MessageBox.Show("Attenzione non ci sono riparti disponibili ! Contattare l'amm.re del DB")
Else
While (dtRead.Read())
codiceProvincia = dtRead.Item("CODPROVINCIA")
codiceComune = dtRead.Item("CODCOMUNE")
codtipoelezione = dtRead.Item("CODTIPOELEZIONE")
Dim blob As OracleBinary = dtRead.GetOracleBinary(4)
'Dim blob As OracleBlob = dtRead.GetOracleBlob(4)
Dim indice As Integer = blob.Length
Dim nomefile As String = "Riparto Seggi" & "-" & dataElezione & "-" & codtipoelezione & "-" & codiceProvincia & "-" & codiceComune
Dim fileXML(indice) As Byte
End While
End If
Catch ex As OracleException 'catch per eccezioni Oracle
Select Case ex.Number
Case 12545
MessageBox.Show("Il database è al momento non disponibile.")
Case Else
MessageBox.Show("errore database: " & ex.Message.ToString)
End Select
Catch ex As Exception
MessageBox.Show("Errore Apertura DB DDE : " & ex.Message & vbCrLf & "StackTrace : " & ex.StackTrace, "Errore", MessageBoxButtons.OK, MessageBoxIcon.Error)
End
Finally
riparti.Dispose()
'dbElezioniDDE.Close()
'dbElezioniDDE.Dispose()
End Try
End Sub

I'm sorry but the post was incomplete!
Then the problem is when I read the XML data
As OracleBinary dtRead.GetOracleBinary
Dim blob As OracleBinary = dtRead.GetOracleBinary(4)
Dim indice As Integer = blob.Length
that by obtaining blob.Length = 0
while the other fields in the select statement is accurate
Thanks

SQLite Inserts Taking Longer and Longer

The application I'm working on makes repeated calls to a webservice to get data that is then cached in a local sqlite db for the user. Once the db hits ~5mb it starts taking painfully long to run each set of inserts. Calls to the webservice remain quick. There had been an issue with XML not being garbage collected, but I fixed that and now the profiler shows consistent memory usage.
I've tried running the inserts with indexes on and off. I've tried batching the inserts in transactions of 100, or the entire set. The db calls are synchronous.
Running the queries against the database directly (not through the AIR application) suggest that there isn't a slowdown at the 5mb mark there, which is consistent with my experiences with SQLlite. Restarting the application and continuing to download data into an existing project does not resolve the issue, it starts off slow.
So...does anyone have any ideas of other things to try to get insert performance up to a reasonable level? Has anyone else run into similiar issues? Is anyone inserting into 20mb+ dbs and not seeing degrading performance?
Thanks for the help!

Guess I posted prematurely. Looking closer I realized there was a select happening during this process against a text column without an index. The slowdown was just the increasing cost of looping through the the entire dataset looking at strings that often shared a fairly sizable starting substring. Chalk another problem up to the importance of appropriate indexes in your db!

Maintenance jobs taking longer and longer

On 2 of our GroupWise servers the weekly maintenance jobs are taking much longer to run.
What used to finish before I got in at 7:30am is now still running at 4PM right now on one of the servers. Last monday, they finished by noon.
We are running GroupWise 8.03 on Netware.
The two servers have about 300 Gig of data each.
The issue of maintenance jobs running later started a few months ago, but today is the worst.
Should I increase the GWWorker threads from to something higher? I think I may want to push the startup times earlier too.
Other ideas?
thanks
Phil J

Takes longer and longer to move between pages and files...little ball rolls and I cant move

I got a new harddrive installed this year and it is difficult to move between pages or open or close anything instantly...waiting time varies...

Let's establish some specifics:
What model MBA do you have?
How much RAM
What HD? Original PATA drive, original SSD design or newer style SSD/RAM drive?
The file(s) that we're working with, what are they? How large are they and what program(s) are we using in conjunction with them?
We need to try and figure out if this is an application or an OS X issue.

Compressor times getting longer and longer...what is going on?

I burn two game dvds per week about the same times (1hr-1hr 10min. I have been using compressor preset of 90 min best(mpeg-2) and then upping the bit rate to get 3.4 to 3.8 gb per dvd. The times to process are getting ridiculous. Normally it would take 2-3 hrs to process but in the last week the last 3 compressor processing times were 5hrs, 7hrs, and then today 22hrs. As far as I know I haven't changed anything. What could bee going on and where should I check first? Im' using FCS 2 Thanks!

In case you haven't already, try some of the things outlined in the Troubleshooting Basics for Compressor.
For your scenario, I would try to the Clear QMaster Cache first. If that doesn't seem to solve anything, try Repair File Permissions, then Delete Preferences.
Or are those roads you've travelled already?

How to view contents in Long Raw datatype column

Hi,
We have two node RAC database with 10.2.0.4.0 version.
OS - IBM AIX.
We have a table with a column with datatype "LONG RAW" in production. It stores image files.
We need to send the images from few rows to third party vendor. Basically, they need to view the images.
Earlier, I have exported to dump file using datapump and sent to vendor. but vendor is telling that they are not able to view the images. Can you please suggest best method to transfer the images (LONG RAW datatype) and the method to view them.

Can you please suggest best method to transfer the images (LONG RAW datatype) and the method to view them.How is the vendor trying to use the extracted images? Data exported with datapump must be imported into another database with datapump. The same applies to the exp utility (must use imp to load into a database).
If you're careful you should be able to write a binary file using utl_file.
Regarding the long raw, is there any way you could convert to BLOBS? Longs and Long raws are notoriously hard to work with

Mapping CLOB and Long in xml schema

Hi,
I am creating an xml schema to map some user defined database objects. For example, for a column which is defined as VARCHAR2 in the database, I have the following xsd type mapping.
<xsd:element name="Currency" type="xsd:string" />
If the oracle column is CLOB or Long(Oracle datatype), could you please tell me how I can map it in the xml schema? I do not want to use Oracle SQL type like:
xdb:SQLType="CLOB" since I need a generic type mapping to CLOB. Would xsd:string still hold good for CLOB as well as Long(Oracle datatype) ?
Please help.
Thanks,
Vadi.

The problem is that LONGs are not buffered but are read from the wire in the order defined. The problem is the same as
rs = stmt.executeQuery("select myLong, myNumber from tab");
while (rs.next()) {
int n = rs.getInt(2);
String s = rs.getString(1);
The above will fail for the same reason. When the statement is executed the LONG is not read immediately. It is buffered in the server waiting to be read. When getInt is called the driver reads the bytes of the LONG and throws them away so that it can get to the NUMBER and read it. Then when getString is called the LONG value is gone so you get an exception.
Similar problem here. When the query is executed the CLOB and BLOB locators are read from the wire, but the LONG is buffered in the server waiting to be read. When Clob.getString is called, it has to talk to the server to get the value of the CLOB, so it reads the LONG bytes from the wire and throws them away. That clears the connection so that it can ask the server for the CLOB bytes. When the code reads the LONG value, those bytes are gone so you get an exception.
This is a long standing restriction on using LONG and LONG RAW values and is a result of the network protocol. It is one of the reasons that Oracle deprecates LONGs and recommends using BLOBs and CLOBs instead.

Can't fetch clob and long in one select/query

I created a nightmare table containing numerous binary data types to test an application I was working on, and believe I have found an undocumented bug in Oracle's JDBC drivers that is preventing me from loading a CLOB and a LONG in a single SQL select statement. I can load the CLOB successfully, but attempting to call ResultSet.get...() for the LONG column always results in
java.sql.SQLException: Stream has already been closed
even when processing the columns in the order of the SELECT statement.
I have demonstrated this behaviour with version 9.2.0.3 of Oracle's JDBC drivers, running against Oracle 9.2.0.2.0.
The following Java example contains SQL code to create and populate a table containing a collection of nasty binary columns, and then Java code that demonstrates the problem.
I would really appreciate any workarounds that allow me to pull this data out of a single query.
import java.sql.*;
This class was developed to verify that you can't have a CLOB and a LONG column in the
same SQL select statement, and extract both values. Calling get...() for the LONG column
always causes 'java.sql.SQLException: Stream has already been closed'.
