The Broken Statistics: "parse count (total)" and "session cursor cache hits"

The values provided by the “parse count (total)” and “session cursor cache hits” statistics are subject to several bugs. And, what’s worse, for years Oracle didn’t care to fix it. This is my impression, at least.

Then, when few weeks ago I read in the Oracle Support note 13837105.8 (Bug 13837105 – statistics “parse count (total)” and “session cursor cache hits” miscounted) that the bug introduced in 11.2.0.3 was fixed, I hoped that others bugs in this area were fixed as well.

Unfortunately, it’s not the case. What a disappointment!

Even though several posts were already wrote about this topic (e.g. here and here; check the comments as well…), I thought it could be useful to summarize what the current status is.

Oracle Database File System (DBFS) Enhancements in Oracle 12c

Oracle 12c includes a really neat feature I first mentioned after Oracle OpenWorld 2012. You can now access your DBFS file systems over HTTP/HTTPS, FTP or WebDAV. I’ve been having a play with it over the last couple of days, so I thought I would write it up here.

This should be quite a welcome addition for those people on platforms other than Linux, who don’t get to use FUSE.

As mentioned in the article, WebDAV support under Windows 7 broken. Even the Oracle manual has a screen shot from Windows XP. I can’t believe Windows 7 has been out all this time and Microsoft have not bothered to fix it…

Cheers

Oracle 12cR1 RAC Installation on Windows 2012 Using VirtualBox…

After having a play with Oracle 12c on Windows 8, I decided to give Windows Server 2012 a go. Here is the resulting virtual RAC installation.

As you would expect, much of the process is pretty similar to the 11gR2 RAC installation on Windows 2008.

Scripts to Download Oracle Database 12c Release 1 Documentation

In the past (here and here) I already shared with you the scripts I used to download the documentation related to Oracle Database. The aim of this short post is to provide the scripts I just wrote for the latest version: 12c Release 1.

Happy download as well as happy reading!

PS: it is interesting to note that the number of manuals is more or less stable. Some were added (e.g. SQL Tuning Guide), some were removed (e.g. all related to OWB).

Oracle 12c: XMLIndex Support for Hash Partitioning

XMLIndex support for Hash Partitioning is now also supported in Oracle 12c. In Oracle 11 there was already support for RANGE and LIST partitioning, but not yet for HASH partitioning.

Oracle 12c: PGA_AGGREGATE_LIMIT

There is no difference in behavior between PGA_AGGREGATE_LIMIT being explicitly set or being set to
