This tip is especially useful when migrating to autonomous. The reason is that to enable the magic of the the autonomous database there are things that cannot be done. One such thing is that there are a lot of session settings you cannot use. To see what APIs you can no longer use you can look at the documentation. If you look at alter session there are a number of “alter session set …” that are available. But many you ..read more

Sometimes new things that are really useful show up in new versions and you can miss it if you’r not paying close attention. EZ Connect Plus is one such feature for me. You may think it is not new and that it has been there for a long time. You’d be correct EZ Connect is not new, but the Plus moniker is. In version 19 that was added. I never noticed and then I was looking for how to connect ..read more

This turned into a miniseries. First it was about focusing on a cell and then on entering the cell in edit mode, but I figure there is a related thing one might want to do. You could want to read the data in a cell once the Interactive Grid (IG) has been loaded. Maybe you need it for some other processing or you want to present something in the IG also in another region. Say that you show the user ..read more

A recent post talked about setting up a Base DB Service in OCI and finished with logging into the OS of the srvice and there connecting to the DB. What we often want to do is to be able to connect to it directly from our own computer to use the tools and workflow we have in place. This post is about how to set that up. First you head back into OCI and look at the properties of your ..read more

I recently wrote about how you set focus on a certain cell in an interactive grid. As often is the case, a solution may work well in many cases but there are some cases where something additional is needed. Say that getting one cell in an interactive grid is what you of want, but some cases are so obvious that the user would want to edit a certain cell once the grid is loaded with data. In this case we ..read more

You may already have one or two free autonomous databases at OCI. Why then would you want a lower tier database offering, a database that is not autonomous? It turns out there are many reasons why you may want this. No matter what your reason is, setting it up is pretty easy. One thing before you start though, you canot stop it to stop spending money. You have to then terminate the service and later recreate it if you want ..read more

When an interactive grid is populated with data, most of the time the default setup is great. But for certain applications you know that the user will want to have a certain cell on a certain row in the grid being in focus. Sure you can leave it and just let the user click on it every time. It’s not like a single click is very hard. But helping them be the most productive they can is what most of ..read more

If you are working with Python and using the oracledb driver you may suddenly encounter DPI -1032 – “user name and password cannot be set when using external authentication”. The issue is with using a wallet for authentication. I encountered it on a server where the version of the oracedb-driver had been slightly upgraded. It was developed and working fine on oraceldb 1.2.2. On 1.3.0 I could ot get it to work. Upgrading to 1.3.2 got it back in working ..read more

This post is part of a series that starts with this post. Withy having looked at a bunch of things we can do with something as simple as an Auto-REST enabled view up to and including adding security, I just want to finish off with showing that having a view in the first place is not needed If all you want is a GET-service for a SQL. AUTO-Rest gives you many more things automatically, both like all forms of DML. You can of course get it without AUTO-rest, but for now let’s just have a quick look at a read access (GET). If you go back to the first post in this series, we rest-enabled a view. Th ..read more

This post is part of a series that starts with this post. Having gone through much of what can be done with a basic REST-service earlier in this series, it is time to look at securing the service. When you can access a service with noting noire than just the URL, then so can anyone else that has access to sen toe ORDS-server the URL. Not only can they read, but if the view allows writing then they can do that too as an autoREST view has DML capability too in the generated API. In the example used for this series it will not work as the view goes against a view Oracle has defined and that cann ..read more
