Missing Documentation for error in SQL.

Hi,
In my application when i try to connect to my .mdf file I got the below error. When I checked for documentation on this error @
http://technet.microsoft.com/en-us/library/cc645603(v=sql.100).aspx
I couldn't find the same in the list.
Error Details : "A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow
remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
Is this missed to document? Can you please confirm.
Please help me in finding documentation on this error.
Thanks
Swapna

Hi,
Thank you for posting in SQL Server Forum.
“SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified” is a common error message when connecting to a SQL Server.
Is it a local instance or remote instance? Default instance or Named instance? What’s the SQL Server version and edition?
The possible cause of this issue could be SQL Server Database Engine is not running, when the server name was typed incorrectly, or when there are network problems or firewalls.
Please check the following suggestions for troubleshooting this issue:
1. Make sure SQL Server Service is running
2. If a named instance, make sure SQL Server browser service is running
3. Make sure SQL Server is configured to allow remote connections
4. Check the SQL Server error log. View the SQL Server error log by using SQL Server Management Studio or any text editor. By default, the error log is located at Program Files\Microsoft SQL Server\MSSQL.n\MSSQL\LOG\ERRORLOG
and ERRORLOG.n files.
Here is the document regarding how to troubleshoot the error message.

Documentation for error codes from tpcall()

Dear all,
while investigating a particular error-handling scenario I realized that the documentation for tpcall() was changed between Tuxedo 6.5 and 7.1.
In the 6.5 docs it's stated that after a TPESVCFAIL error you can do tpcall(..., TPNOTRAN) as long as you haven't run out of TRANTIME.
In the 7.1 (and onwards) docs it's stated that after a TPESVCFAIL error you can only do tpacall(..., (TPNOBLOCK|TPNOREPLY|TPNOTRAN))
In the 6.5 docs this is only stated after TPETIME (which makes some kind of sense - you're already late so don't do a lot of more time-consuming stuff).
On the other handl, in a section in the Tuxedo 10.0 docs about error handling (http://edocs.bea.com/tuxedo/tux100/pgc/pgerr.html#wp1155712) you're again told that it's OK to use tpcall() (and recommended to use TPNOTRAN if doing so)
Is this related to multi-threading, or why was the documentation changed?
Testing shows that you can actually do tpcall(..., TPNOTRAN) after a TPESVCFAIL using Tuxedo 8.1. (after a TPETIME it's another story, but I'm OK with that.) Am I the only one being confused by this?
Best regards,
/Per

I just checked the XATMI spec (dated November, 1995....) which states the following regarding tpcall() failures:
[TPESVCFAIL]
The service routine sending the caller’s reply called tpreturn( ) with TPFAIL. This is an
application-level failure. The contents of the service’s reply, if one was sent, are available in
the buffer pointed to by *odata. If the service request was made on behalf of the caller’s
current transaction, the transaction is marked rollback-only. Note that so long as the
transaction has not timed out, further communication may be attempted before rolling back
the transaction. Such attempts may be processed normally or may fail (producing an error
return or event). Such attempts should be made with TPNOTRAN set if they are to have
any lasting effect. Any work performed on behalf of the caller’s transaction is rolled back
upon transaction completion.
This is consistent with the 6.5 documentation (and 8.1 behaviour). Has the XATMI spec been updated, or what was the rationale for changing the behavior?
Best regards,

Missing Documentation for kernel26/laptop_mode.txt

Since the kernel26 package is stripped of all documentation, I can't get the laptop_mode script for 2.6.7. Do you compile your own kernel? Could you post the laptop_mode.txt on this thread please?

How to conserve battery power using laptop-mode

Introduction
Laptopmode is used to minimize the time that the hard disk needs to be spun up,
to conserve battery power on laptops. It has been reported to cause significant
power savings.

* The short story
* Caveats
* The details
* Tips & Tricks
* Control script
* ACPI integration
* Monitoring tool
The short story
To use laptop mode, you don't need to set any kernel configuration options
or anything. You simply need to run the laptop_mode control script (which
is included in this document) as follows:
# laptop_mode start
Then set your harddisk spindown time to a relatively low value with hdparm:
hdparm -S 4 /dev/hda
The value -S 4 means 20 seconds idle time before spindown. Your harddisk will
now only spin up when a disk cache miss occurs, or at least once every 10
minutes to write back any pending changes.
To stop laptop_mode, run "laptop_mode stop".
Caveats
* The downside of laptop mode is that you have a chance of losing up
to 10 minutes of work. If you cannot afford this, don't use it! It's
wise to turn OFF laptop mode when you're almost out of battery --
although this will make the battery run out faster, at least you'll
lose less work when it actually runs out. I'm still looking for someone
to submit instructions on how to turn off laptop mode when battery is low,
e.g., using ACPI events. I don't have a laptop myself, so if you do and
you care to contribute such instructions, please do.
* Most desktop hard drives have a very limited lifetime measured in spindown
cycles, typically about 50.000 times (it's usually listed on the spec sheet).
Check your drive's rating, and don't wear down your drive's lifetime if you
don't need to.
* If you mount some of your ext3/reiserfs filesystems with the -n option, then
the control script will not be able to remount them correctly. You must set
DO_REMOUNTS=0 in the control script, otherwise it will remount them with the
wrong options -- or it will fail because it cannot write to /etc/mtab.
* If you have your filesystems listed as type "auto" in fstab, like I did, then
the control script will not recognize them as filesystems that need remounting.
* It has been reported that some versions of the mutt mail client use file access
times to determine whether a folder contains new mail. If you use mutt and
experience this, you must disable the noatime remounting in the control script
by setting DO_REMOUNT_NOATIME=0.
The details
Laptop-mode is controlled by the flag /proc/sys/vm/laptop_mode. This flag is
present for all kernels that have the laptop mode patch, regardless of any
configuration options. When the flag is set, any physical disk read operation
(that might have caused the hard disk to spin up) causes Linux to flush all dirty
blocks. The result of this is that after a disk has spun down, it will not be spun
up anymore to write dirty blocks, because those blocks had already been written
immediately after the most recent read operation.
To increase the effectiveness of the laptop_mode strategy, the laptop_mode
control script increases dirty_expire_centisecs and dirty_writeback_centisecs in
/proc/sys/vm to about 10 minutes (by default), which means that pages that are
dirtied are not forced to be written to disk as often. The control script also
changes the dirty background ratio, so that background writeback of dirty pages
is not done anymore. Combined with a higher commit value (also 10 minutes) for
ext3 or ReiserFS filesystems (also done automatically by the control script),
this results in concentration of disk activity in a small time interval which
occurs only once every 10 minutes, or whenever the disk is forced to spin up by
a cache miss. The disk can then be spun down in the periods of inactivity.
If you want to find out which process caused the disk to spin up, you can
gather information by setting the flag /proc/sys/vm/block_dump. When this flag
is set, Linux reports all disk read and write operations that take place, and
all block dirtyings done to files. This makes it possible to debug why a disk
needs to spin up, and to increase battery life even more. The output of
block_dump is written to the kernel output, and it can be retrieved using
"dmesg". When you use block_dump, you may want to turn off klogd, otherwise
the output of block_dump will be logged, causing disk activity that is not
normally there.
If 10 minutes is too much or too little downtime for you, you can configure
this downtime as follows. In the control script, set the MAX_AGE value to the
maximum number of seconds of disk downtime that you would like. You should
then set your filesystem's commit interval to the same value. The dirty ratio
is also configurable from the control script.
If you don't like the idea of the control script remounting your filesystems
for you, you can change DO_REMOUNTS to 0 in the script.
Thanks to Kiko Piris, the control script can be used to enable laptop mode on
both the Linux 2.4 and 2.6 series.
Tips & Tricks
* Bartek Kania reports getting up to 50 minutes of extra battery life (on top
of his regular 3 to 3.5 hours) using very aggressive power management (hdparm
-B1) and a spindown time of 5 seconds (hdparm -S1).
* You can spin down the disk while playing MP3, by setting the disk readahead
to 8MB (hdparm -a 16384). Effectively, the disk will read a complete MP3 at
once, and will then spin down while the MP3 is playing. (Thanks to Bartek
Kania.)
* Drew Scott Daniels observed: "I don't know why, but when I decrease the number
of colours that my display uses it consumes less battery power. I've seen
this on powerbooks too. I hope that this is a piece of information that
might be useful to the Laptop Mode patch or it's users."
* One thing which will cause disks to spin up is not-present application
and dynamic library text pages. The kernel will load program text off disk
on-demand, so each time you invoke an application feature for the first
time, the kernel needs to spin the disk up to go and fetch that part of the
application.
So it is useful to increase the disk readahead parameter greatly, so that
the kernel will pull all of the executable's pages into memory on the first
pagefault.
The supplied script does this.
* In syslog.conf, you can prefix entries with a dash ``-'' to omit syncing the
file after every logging. When you're using laptop-mode and your disk doesn't
spin down, this is a likely culprit.
* Richard Atterer observed that laptop mode does not work well with noflushd
(http://noflushd.sourceforge.net/), it seems that noflushd prevents laptop-mode
from doing its thing.

Java.sql.SQLException: Error while trying to retrieve text for error ORA-24

Hi All,
Am having serious problem with ORA-24327 and the behavior is very very unpredictable. I have couple of environment where the same error comes in different context. The recent one was surprising. I have describe bellow the environment configuration and the stack trace. The error which surprised me was when I use type � 3 driver while starting weblogic I get ORA �24327 but when I use Type �4 it starts properly. If you could kindly provide solution it would be great help. I would also appreciate if u can provide information which driver to use where performance is the major concern. I would also appreciate if u could provide feed-back from the industry about booth the driver. Apart from that I have couple have environment where it occurs when 10/12 user access simultaneously. All the open connection is closed in program properly still am getting the error.
Thanks in anticipation.
Cheers,
Tapas

Hi,
I guess you can try some of these:
- Make sure you're not missing an entry inside your tnsnames.ora file. Thin driver does not require the information inside that file, as opposed to Weblogic's OCI driver. If you are able to connect to the DB using a thin driver, then the problem is most probably (WL)driver-related.
- Make sure you've properly configured the DB user / password inside your weblogic.properties (config.xml if WL6+).
- Make sure you're able to access all drivers and classes required (PATH, CLASSPATH, etc...)
- Make sure the OCI driver version you are using is fully compatible with the Oracle (server) version you are pointing to.
- Try to access the DB user through some other client (for instance, SQLPlus*).
Hope this is of some help,
Freddy.

Error level documentation for 36xx errros

Hi,
Can anyone point me at the documentation for the Error messages for these errors for Sybase 15.x
3606, 3607, 3619, 3620, 3622
Looking in ...
Exception Handling Errors (3600s)
but they seems to be missing.
I can see them in the 12.x manual but I think the severities have changed.
Just wanting to confirm.

Thanks - is any of this docmented anywhere that a developer can read it ?
Since its changed since V12 it might be useful to update the manual.
Its also a little confusing and inconsistent in that sysmessages shows the errors as severity 10.
       select severity from master..sysmessages where error = 3607
but the errors are shown as
       Msg 3607, Level 16, State 0
       Server 'S1', Line 1
       Divide by zero occurred.

The boot configuration data for your Pc is missing or contains errors: error code 0x000014c

Hello,
See if any body may help here... I get this blue screen:
RECOVERY
Your PC needs to be repaired:
The Boot Configuration Data for your PC is missing or contains errors.
file:\\EFI\Microsoft\Boot\BCD
Error code: 0xc000014c
You'll need to use the recovery tools on your installation media. If you don't have any installation media (like a a disc or USB device), contact your system administrator or PC manufacturer.
Press Esc for UEFI Firmware Settings
First I was able to get into the option 11 and run the whole factory reset, i was so happy because I tought it will be easy.. but then after I did the factory reset.. I keep getting this blue screen. if I press ESC I get into this next screen:
F1 System Information
F2 System Diagnostics
F9 Boot Device Options
F10 BIOS Setup
F11 System Recovery
ENTER - Continue Startup.
this is what happen when I click any of this options:
F1 I get into the System Information with no problems, then I click <ESC> to continue and get back to the last screen... then I press F2 and super, I am able to run Memory Test and Hard Drive Check 100% with no problems in any of those, after I am done with my teste I press exit and I am back to the F1,F2, ETC menu... now I want to try F9, F10 or F11. bummer.. in this 3 options I get back to the blue screen described at the beggining of this post. (I already connect a USB with an boot loader, which works perfectly)
so I can't do anything, nothing at all!! crazzines.
So what I did to check why I can't get into the BIOS or at least to boot from my USB... I removed the botton cover of my laptop and removed the hard drive and that's how then I was or I am able to Log into the BIOS, - I did the changes to boot first from the USB and then from the HD and this is how I was able to boot from the USB - BUT If I connect back the Hard drive, I am not able to get into the BIOS or boot from the USB - so basically I am stuck in this blue screen and I can't boot from a USB if I have the HD connected.. I can't use any option.. no BIOS, nothing.. only if again, i disconnect the HD.
This is an:
HP ENVY TS Sleekbook 4
PRODUCT NUMBER D1A99UA#ABA
SYSTEM BOARD ID: 1894
Bios F.25
**** I though that by updating the BIOS I may be able to get help, nothing. What I did is, I removed the HD and then and boot from the USB and with a DOS command propmt I excecuted the Bios Update from F.21 to f.25... but again, when I installed the hard drive back, BUMMER, nothing I can't do nothing but this silly blue screen.
Any idea of what should I do?
Thanks in advance.
This question was solved.
View Solution.

If you can't access BIOS with the hard disk connected, you certainly won't be able to boot to the usb recovery flashdrive. That is indicative of a failed hard disk.
Install a new hard disk and then boot to the recovery flashdrive.

Now i am getting different exception. But still the standalone codeis working.
any clues why I am getting this exception. I will send the code andthe weblogic
properties file for reference if u need.Good. No, I don't need it. Now make sure the library path that the OS
uses to find
Oracle libraries, and our driver libraries etc., is in the same order

Missing mapping for field error

Here is the set up:
Person extends Party using InheritanceType.JOINED
Household extends Party_Relationship using InheritanceType.JOINED
Household has a Set of Persons mapped One to Many unidirectional
When I use PrimaryKeyJoinColumn on the Person and/or Household to rename the column say to PERSON_POID instead of PARTY_POID and when adding Persons to the Household Set the following error occurs:
oracle.toplink.essentials.exceptions.DescriptorException
Exception Description: Missing mapping for field [PERSON.PARTY_POID].
Descriptor: RelationalDescriptor(com.dhsnet.cms.domain.Person --> [DatabaseTable(PARTY), DatabaseTable(PERSON)])
What am I missing? If I do not use the PrimaryKeyJoinColumn mapping this error does not occur. I am stumped! Any help is greatly appreciated.
Here are the mappings:
@Entity
@TableGenerator(name="party", table="generator", pkColumnName="table_name",
valueColumnName="key_value", pkColumnValue="party", allocationSize=1)
@Table(name="PARTY")
@Inheritance(strategy=InheritanceType.JOINED)
@DiscriminatorColumn(name = "PARTY_TYPE")
public abstract class Party extends AbstractEntity{
@Entity
@DiscriminatorValue("PERSON")
@PrimaryKeyJoinColumn(name="PERSON_POID")
public class Person extends Party{
@Entity
@Table(name="PARTY_RELATIONSHIP")
@TableGenerator(name="party_relationship", table="generator", pkColumnName="table_name",
valueColumnName="key_value", pkColumnValue="party_relationship", allocationSize=1)
@Inheritance(strategy = InheritanceType.JOINED)
@DiscriminatorColumn(name = "PARTY_RELATIONSHIP_TYPE", discriminatorType=DiscriminatorType.STRING)
public abstract class PartyRelationship extends AbstractEntity {
@Entity
@DiscriminatorValue(value="HOUSEHOLD")
@PrimaryKeyJoinColumn(name="HOUSEHOLD_POID")
public class Household extends PartyRelationship {
On the Household Object:
@OneToMany
@JoinTable(joinColumns = @JoinColumn(name="HOUSEHOLD_POID"),
inverseJoinColumns = @JoinColumn(name="PERSON_POID"))
protected Set<Person> getMembers() {
return members;
}

This looks to be the same/related issue that has already been entered. See
https://glassfish.dev.java.net/issues/show_bug.cgi?id=1586
The alternative like you mentioned, is to not use a PrimaryKeyJoinColumn to rename the column in the joined inheritance case.
Cheers,
Guy

What is this error java.sql.SQLException: Bad format for number ?

Dear All,
I am reading few values from database. Then I get this error "MyError:Error : java.sql.SQLException: Bad format for number 'Sarawak' in column 6. " So what is this error referring to. I have checked the database column and its value fits according the data type. Any hints please?

I have checked the database column and its value fits according the data type.Check again. Then check again. Keep checking until you find your error. You are trying to read a string containing "Sarawak" as a number. You have "getInt(6)" or other numeric type, and the 6th column in the select statement is not numeric.

Distribution KSV5 dump: K5 011 ERROR IN COIOB MISSING BUKRS FOR OBJECT

Hi All,
Have you met following short dump whenever? It apears during distribution cycle run in update mode? Unfortunately I am not able to find any OSS Notes that could fix it:
Short text of error message:

The 9iAS documentation is available on OTN at:
http://download.oracle.com/docs/cd/A97688_13/index.htm#toplink
