Oracle Portal and APEX RSS Feeds and Traffic Analysis

I try to avoid advertising in this blog, but I'm going to break that rule as I have had a few inquiries lately on these topics. C2 has new product offerings that provide RSS feeds for Oracle Portal and APEX. For details, contact C2. C2 also has a web traffic capture and reporting tool. This tool can be used on any site, but has a few specific capabilities related to Oracle Portal and Application Express. Again, for details, contact C2.

And just an update on my last post -- the fine folks on the APEX team released patch 833890 to solve this import issue. You can get the patch at http://metalink.oracle.com.

APEX 3.2 Gives Error on Import - ERR-3331

Just a quick note regarding the 3.2 import process... APEX added a number of enhancements and checks during the import of an application. The downside is that these introduced some negative performance characteristics. If you are importing a medium to large size app you are likely to get either a timeout or an error message:
ERR-3331 This page was already submitted and can not be re-submitted.

Oracle has confirmed the problem and a fix is in the works. I'll update this post when the patch is available.

The good news is that the application will import anyway. After you get the error, just go back to the builder and check to make sure the import was successful.

25-Mar-2009: More good news -- the fine folks on the APEX team released patch 833890 to solve this issue. You can get the patch at http://metalink.oracle.com.

APEX 3.2 - save state before branching

Just a quick note about a little known new feature in APEX 3.2: save state before branching. When creating a branch and setting items with values, you now have the option to either pass those values in the URL or to have APEX set them into session state prior to doing the branch.

Application Express (APEX) 3.2

We went through the upgrade to 3.2 last night and it was very smooth. We had a couple minor challenges but that is because of our unique environment.

1. We have an SSO configuration. APEX does not specify the owner of the package wwv_flow_custom_auth_sso when it generates the return link for SSO. This means that the APEX_PUBLIC_USER (or whatever user your DAD is configured to use) must have a synonym to wwv_flow_custom_auth_sso. You can also create a public synonym so long as one does not exist for another application.

2. I noticed that some of our custom stylesheets give a slightly different look with date picker items. This may be due to a change in the way APEX 3.2 generates date pickers. I'll look into it and post anything I find.

3. Apex has a new database schema. It has finally moved to APEX_030200. [ removed a comment about the version that was wrong... thanks Patrick! ]

A very easy install, really. Thanks to the APEX team once again!
