No matter the file length it gives me this error. It does this at crypto.close(). I've googled around and still is...
|
|
|
|

I've also taken out the encryption and found out that the problem still exists without encryption.

A few statements:
1. I don't know why you are storing the file size; you sure don't need it to store or retrieve the file data.
2. If the crypto code is unhappy about the file size or file data, then the size or data are probably wrong and the problem is NOT in encryption.
3. As long as you fail to store and retrieve binary data, it makes no sense to complicate things with encryption/decryption.
First create methods that deal with arbitrary blobs; then add some methods that handles encryption. So start with a text file, think of it as binary data, store it in a blob, retrieve the blob, store it in a new file, and compare both files. And don't mix separate functions into a single method.
4. Don't create a bunch of code, and then discover it doesn't work; you are wasting your time. Write a small bit of code, and check it works absolutely fine. Then add some, test, fix, and repeat.
5. This has been going on since medio December; all it takes is four methods, each less than 20 lines of code.
6. Suggestion: if you need only one field, use ExecuteScalar.

1) I figured that out already
2) Pin pointed that problem
3) Never dealt with databases before
4) NEVER did that and have constantly repeated testing... I'm always encountering one error.
5) SMDH... I ain't even going to respond there.... this is different direction than before.
6) Thanks for the suggestion...
With little experience inserting into the database and no clue on how to extract the file is where my problem is.

Dear all,
I'm trying to do a project on birds and saving information such as the scientific classification and naming. I want to save images of birds in the database so I can display them later in forms or reports when the user does a query about a bird. For some birds I have more than one image so I want to include all images.
My question is how I can do that, I mean how can I store the images in oracle?
I'm using Oracle 9i. So far I have created a table to store the birds and their classification and tried to google about storing the images but no luck yet 
Could you please help me with that..
I have a quite little background in oracle 9i :$
Thanks folks

I do wonder what you used as the serch criteria, I find pleanty of info with the following oracle 9i store images
If there are to be mode than 1 images per bird then you need a separate table for the images with a FK to the birds table.
BirdsTable
BirdID (PK)
BirdName
ImageTable
ImageID (PK)
BirdID (FK)
BlobField

Hello,
All of a sudden we are experiencing poor performance on our DB server, something that would like 5 seconds is now taking 25 minutes are not completing the query. Checked the sql server logs, nothing.
Only difference is we have started to re-index all our indexes. We started this on Monday, and have schedules set up so that we have a few done every day. Does this hamper the performance? This is the first time the indexes are being re-indexed. Any ideas as where to look for SQL performance?
Thanks!

Hello,
About twice a month our sql server agent stops running all the jobs, till the server has been restarted. on checking the error log we found this message, approximately every 5 seconds in the log file till the time the server was re-started.
Message
[165] ODBC Error: 0, Memory allocation failure [SQLSTATE HY001]
It fails on this job that takes about 12 hours to run.
Any ideas on this error message?
Thanks.

This may be unrelated but check your maximum memory. We had a problem where sql server quit running and it was because the memory was set to the default which meant sql took all the memory and the OS had none.

Hi,
I have a scheduled job set to run on server A, with 5 steps. One of the stored procs in this job, step 4 is taking a long time to complete, we moved it to another which does not take much time to execute. Now we are trying to change this step so it uses the other server B.
So on server A, I tried something like this -- exec serverB.database.dbo.sp_load_data.
This is not working. Is there a way to execute stored proc on another server?
Thanks!

It looks like you're using SQL Server so setting up a linked server on Server A should be all you need.

I am new to Linked servers.
If you have an article or some sort handy could you please post it.
Thanks so much for your time.

I see something set up for tables and view thru Linked servers.
I am using a stored proc. how would we do that?
|
|
|
|
|
Once the link is setup it can be called by
EXEC [linkedserver\instance].database.schema.sp I find it best to put [] around the linked part so I do not forget if I have a named instance (as shown).

|
|
|

I tried this.
Looks like RPC needs to be enabled on the remote server? is that the only way to go about?

I have a requirement that specifies that I need to block the access of a process to some records that are used by another process. This can be easily done by adding a Locked(bit) column and a ProcessID(int) column. The problem appears later in the specification when it says that in the case a process dies the rows locked have to be unlocked. The same must apply if the process is blocked in some way. Another problem is the fact that the login with which these processes run does not have VIEW SERVER STATE permission (nor it can be given that permission) so I can't use sysprocesses view or sp_who procedure.
Is there any way around this or another possible solution?

You fail to mention what db you are using.
If you use Oracle or DB2 you can Select for update...
There's a similar method for SQL server but it locks whole pages instead of records as far as I know.

Just another idea. Could you select the data and then delete it from the table. The data would then have to be persisted in memory or perhaps a different table. Once the process is complete and want's to make the data 'visible' again, it would then restore it to the original table.
