This always happens in any version of Delphi (up to D6 - havent tried in D7), and really isnt due to any problem in DOA. You will see the same error upon loading a project that makes use of a BDE TDatabase component in a shared datamodule. The error comes from forms/datamodules being opened by...

however, CheckConnection() will not work if you have Internal Connection Pooling turned on for your oracle session component. You will receive ccReconnected, but the underlying pooled connection will not actually have been repaired. I posted a possible fix for the problem a while back on these...

I have a minimal oracle dataset, it returns one row with one field. The field is a BLOB that contains a JPG image. Assuming the dataset component is named OracleDataset1, and the field is named Field1 and it is instantiated in the designer as OracleDataset1Field1, how would I go about writing...

Marco, This thread was originally posted by a co-worker of mine, and the problem was subsequently handed off to me to correct. I am not sure how you have taken care of this in version 4, but I thought I should share the patch we came up with for 3.4.6. (this issue was too important to us to...

I dont think I ever got an email through, but this is the code we are using currently to alleviate the problem. It's by no means a permanent fix, and does not even address the real problem of what is raising the errors (evaluating debug information indicates a firewall is killing database...

Hi again marco... I have found another problem in DOA which I feel definately needs to be addressed in the next patch/upgrade. This one has caused all kinds of havoc for us here, until I was finally able to nail down the source of the problem. We are using DOA 3.4.6 in a multi-tier scenario...

Well - I went and "patched" my DOA source with these changes, please consider including them (or some variation thereof) in the next official patch/release. These two changes correct both bugs. OracleData.pas: Near the top of procedure TOracleDataSet.EnableMasterFields: replace with For...

In regards to item #1: I understand how TOracleDataset copies the values to detail datasets, however this only functions when using live datasets. In a MIDAS scenario, where the datasets are nested and ResolveToDataset is False, its the TClientDataSet that actually becomes responsible for this...

I have identified two bugs in the DOA source in relation to updating linked TOracleDataSets using standard "nested" clientdatasets in a remote tier. I searched the forum here and did not see either problem previously mentioned. First bug: TOracleDataSet does not override and implement the...
