How to check for blob corruption

We had successfully inserted the images into the database blob datatype. But, we found some of the images can't be displayed from the application interface, well others are OK.
Is it possisible that the blobs are corrupted, if it is, how to find out which are the ones?
Thank in advance for your help!

Hi,
Assuming that all the images were uploaded successfully using the same tool, then its unlikely that the BLOBs have been corrupted. In fact, its extremely unlikely that BLOBs are being corrupted at all. To the best of my knowledge, there is no way to verify the contents of a BLOB, as the contents are simply application specific raw binary data. Its much more likely to be an issue with the tool used to load the data, the application used to display the data, or the image data itself.
Can you provide some more information about the problem you are experiencing. For example: what application interface are you using, and what sort of error message is being displayed?
I tend to focus on HTTP and web, but here are some things to consider: some image formats are not supported internally within a browser. For example, an image tag that tries to display a Windows bitmap image is going to result in a broken image tag (unless you have a browser plugin that can render bitmap images). Another issue might be that the image format isn't recognized by the version of interMedia that you are using. For example, progressive JPEG images aren't recognized by interMedia until Oracle8i version 8.1.7. (And even then, only setProperties is supported.) However, if your application uses an exception handler of some sort to catch errors from setProperties, then although the data might be stored in the BLOB correctly, the MIME type is NULL. Although you may not be using a web interface to access the data, some of these issues may still be pertinent to your application.
If you can tell us some more information about your application, how you are using interMedia and the errors you are seeing, then we'll try to help.
Thanks,
Simon

How to check for a function module with its description and functionality

Hi all,
How to check for a function module,with its description and its functionality,in detail how can I know the purpose of a particular function module,how to search for a function module which suits my requirement .

Hi,
You can search a FM of your requirement by putting in the Key words and searching for a FM. Like * KEYWORD * and then pressing F4.
Say for example you need to search something regarding converstion.
Search for * CONVERT * and press F4.
If there is something specfic like converting date to something you can give
DATE * CONVERT *
OR
CONVERT * DATE * and press F4.
Once you narrow down your search you will have a Function module documentation inside the Function module. Please note that all the FMs willl not have documentation.

Want to know how to check for new line character in text file

Hi All,
I`m trying to read data from text file. However I`m not sure whether the data is in 1st line or nth line. Now I`m trying to read the text from the readline. But if text is "" and not NULL then my code fails. So I want to know how to check for new line character and go to next line to find the data. Please help.

                    e.printStackTrace();
          return get_count;
     }

You are calling the readline() only once which means you are reading only the first line from the file...
Use a loop (Do-While preferably)
do{
//your code
}while(text == "")

Hi Sundhar,
According to your description, you might want to check the existence of sub folder in a folder of a library using Client Object Model.
Please take the code demo below for a try, it will check whether there is sub folder in a given folder:
public static void createSubFolder(string siteUrl, string libName, string folderServerRelativeUrl)
ClientContext clientContext = new ClientContext(siteUrl);
List list = clientContext.Web.Lists.GetByTitle(libName);
CamlQuery camlQuery = new CamlQuery();
camlQuery.ViewXml =
@"<View Scope='RecursiveAll'>
<Query>
<Where>
<Eq>
<FieldRef Name='FSObjType' />
<Value Type='Integer'>1</Value>
</Eq>
</Where>
</Query>
</View>";
//camlQuery.FolderServerRelativeUrl = "/Lib1/folder1";
camlQuery.FolderServerRelativeUrl = folderServerRelativeUrl;
ListItemCollection items = list.GetItems(camlQuery);
clientContext.Load(items);
clientContext.ExecuteQuery();
Console.WriteLine(items.Count);
if (0 == items.Count)
//create sub folder here
Best regards

How to check & resolve block corruption if no RMAN backup is there?

*<<+MY Findings+>>*
to check block corruption :

select * from v$database_block_corruption;
DB_VERIFY is useful in these situations:
When block corruption is expected;
Forecast any future problems w.r.t. database file/ block corruption;
When you restore files from a tape. It will help knowing if the first file pulled from tape is corrupt, instead of spending hours to extract all of them.

How to check for updates on SCM packages?

Hey guys,
I wondered for some time now how to check for updates on SCM packages, i.e. -git
or -svn ones. Updates for binary packages are automatically updated by pacman,
no problem there. Checking for updates on non-SCM packages from the AUR is
easily done with one of the various helper tools available (personally, I use
slurpy).
However, SCM packages can change without their PKGBUILD changing, so I'm not
notified that I should recompile and update them.
Is there a "proper" way of doing this? Am I missing something?
Thanks in advance!

If your system is booting then u can say that your bootblks are installed.Usually BootBlks are present in 0 & 1 slice of UFS Filesystem
/usr/platform/platform-name/lib/fs/ufs
directory where ufs boot objects reside.
An x86 FDISK partition for the Solaris software begins with a one-cylinder boot slice, which contains the partition boot program (pboot) in the first sector, the standard Solaris disk label and volume table of contents (VTOC) in the second and third sectors, and the bootblk program in the fourth and subsequent sectors. When the FDISK partition for the Solaris software is the active partition, the master boot program (mboot) reads the partition boot program in the first sector into memory and jumps to it. It in turn reads the bootblk program into memory and jumps to it. Regardless of the type of the active partition, if the drive contains multiple FDISK partitions, the user is given the opportunity to reboot another partition.

How to check for impacts due to upgrade

We are plannining to upgrade from 4.7 to ECC6..How to check for impacts on FTP'S,shell scripts and RFC's etc due to the assesment..Please suggest

Hi,
FTP's and Shell scripts are OS dependant not SAP or Database dependant so there will be no change at all unless you upgrade OS too. RFC's are not afected as per guides, notes and my experience.
I´m doing an upgrade from 4.6C to 6.0 with connections with at least 10 systems and none of them had an issue during tests
Good luck

HT6114 how to check for malware on my mac

My macpro is running slow all of a sudden. How do i check for malware?

No need, really. You've shown no evidence that malware would be causing the issue. Furthermore, OS X has its own built-in anti-malware protection. It's unlikely your problem is due to malware. See the following:
Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with visits to:     OS X Maintenance - MacAttorney;
                                  The X Lab: The X-FAQs;
                                  The Safe Mac » Mac Performance Guide;
                                  The Safe Mac » The myth of the dirty Mac;
                                  Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection
          OS X Lion- Protect your Mac from malware
          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

How to check for archivelog backup on a particular date or time?

Dear All,
We have RMAN full database, cumulative and archivelog backup(eg location: Diskgroup A) scheduled on a regular period basis. Assume archivelog location is Diskgroup B. The diskgroup B became full and unable to archive further, since no space. Unable to connect to database, connect internal only until freed error. alert log also shows that archiver error. So the solution for this to clear some space in diskgroup B by removing some old archive logs. In our environment, everyday the archive logs are stored in a separated folder arranged in date wise. I can do that . But before clearing some space, i need to make sure that the folder( or any date folder what im going to delete) is backed up or not. How to check that? Any idea please?
eg: i have archivelogs like this in folders
01_11_2013/
02_11_2013/
03_11_2013/
04_11_2013/
05_11_2013/
06_11_2013/
If i want to remove the folder 01_11_2013/( and its contents ie archivelogs) , how to check whether the archivelogs in this folder 01_11_2013/ is backed up or not?

How to check for missing fields in the file?

Hi friends,
I have a file to file scenario in which if any of the fields have a blank value, i have to put the file back in the source folder. If none of the fields are missing, the scenario should work normally.
Can anybody tell me how can i check for the field lengths and if any of the fields are blank, how do i send it back to the original folder.
Waiting for your responses,
Divija.

Hi Divija,
>>how can i check for the field lengths
Since you need to basically check if the field has a value or not, i dnt think you need to check for the length of the field. Instead, you can use any one of the booloean functions available in the graphical mapping editor to check if the field has a value or not(filed value true or false)
>>how do i send it back to the original folder.
You can maintain a flag variable in the target structure such that if any of the source fields donot have values, the flag's value becomes 1 else it remains 0.
Now, you can check if the value of flag is equal to 1/0 in the bpm and accordingly send the data.
If in case, you donot want the flag to come in the target file that is loaded/sent from the bpm in the end, i think even tat can be taklen care of.
You can create two receiver communication channels and define one file adapter in each such that one has the destination as the actual target directory and the other has the original source directory as the destination.

How to check for the variable passed to a function inside a component

I'm trying to pass a variable to a function inside of a
component in a conditional statement.
How to check the existance of this variable inside the
function so that I can use the right <CFarguments>:
in aForm.cfm I have:
<cfinvoke component="#application.cfcroot#.business.Order"
method="selOrderItems"
returnvariable="q_OrderItems"
OrderItemAbbreviation="Min"></cfinvoke>
<cfset MCompIDs = ValueList(q_OrderItems.OrderItemID)>
<cfif listFind(MCompIDs,attributes.CompID)>
<cfset isM = true>
<cfelse>
<cfset isM = false>
</cfif>
<cfinvoke component="#application.cfcroot#.business.Order"
method="selOrderItems"
returnvariable="q_OrderItems"
OrderItemAbbreviation="SMEnroll"></cfinvoke>
<cfset SM_CompIDs =
ValueList(q_OrderItems.OrderItemID)>
<cfif listFind(SM_CompIDs,attributes.CompID)>
<cfset isSM = true>
<cfelse>
<cfset isSM = false>
</cfif>
<CFIF isSM>
<cfset temppath = frmcreator.buildFrm(isSMFlag=isSM)>
<CFELSE>
<cfset temppath = frmcreator.buildFrm(isMFlag=isM)>
</CFIF>
On aFormComp.cfc where the function is,
I checked the existance of isSMFlag this way and I got error
saying that :
Context validation error for tag CFARGUMENT.; The tag must be
nested inside a CFFUNCTION tag.
How can I properly check the existance of isSMFlag inside the
function so I can use the right cfarguments?
<CFFUNCTION NAME="buildFrm" access="public"
returntype="String" output="No">
<cfif StructKeyExists(arguments, "isSMFlag")>
<CFARGUMENT NAME="isSMFlag" REQUIRED="YES"
TYPE="NUMERIC">
<cfelse>
<CFARGUMENT NAME="isMFlag" REQUIRED="YES"
TYPE="NUMERIC">
</cfif>
........ etc
</CFFUNCTION>

<CFFUNCTION NAME="buildFrm" access="public"
returntype="String"
output="No">
<cfif StructKeyExists(arguments, "isSMFlag")>
<CFARGUMENT NAME="isSMFlag" REQUIRED="YES"
TYPE="NUMERIC">
<cfelse>
<CFARGUMENT NAME="isMFlag" REQUIRED="YES"
TYPE="NUMERIC">
</cfif>
........ etc
</CFFUNCTION>
NOT this way, that is for sure.
The <cfargument ...> tag is for defining the arguments
a function
accepts either optional or not, but they are not required.
Give this a
try to see the differences.
test.cfc
<cfcomponent>
<cffunction name="a">
<cfdump var="#arguments#">
</cffunction>
<cffunction name="b">
<cfargument name="foo">
<cfargument name="bar">
<cfdump var="#arguments#>
</cffunction>
</cfcomponent>
test.cfm
<cfset something = createObject("component","test")>
<cfoutput>
#something.a("blue","green")#
#something.b("blue","green")#
</cfoutput>
Not tested or debugged so watch out for typos.

HOw to check for the Child Elements USing only SAX Parsr?

HI Guyz,
How to check whether there are any Child Elements in an XML file using ONLY SAX parser ??? I have a requirement of checking first whether there is any Child Elements exists for a Element or not and based on that I have to take certain actions. Can anyone suggest me How to do that ???
Thanx
KK

Since SAX is event controlled, you wont know if there's a child element unless you actually bump into it with the Parser. You'll simply get another startElement event after your current one.
