A minor update 4.01 to the XPLAN_ASH utility is available for download.
These are the notes from the change log:
- More info for RAC Cross Instance Parallel Execution: Many sections now show a GLOBAL aggregate info in addition to instance-specific data
- The Parallel Execution Server Set detection and ASSUMED_DEGREE info now makes use of the undocumented PX_STEP_ID and PX_STEPS_ARG info (bit mask part of the PX_FLAGS column) on 18.104.22.168+
- Since version 4.0 added from 22.214.171.124 on the PX *MAX* DOP in the "SQL statement execution ASH Summary" based on the new PX_FLAGS column of ASH it makes sense to add a PX *MIN* DOP in the summary to see at one glance if different DOPs were used or not
A new version of the XPLAN_ASH tool (detailed analysis of a single SQL statement execution) is available for download. The previous post includes links to video tutorials explaining what the tool is about.
The new version comes with numerous improvements and new features. The most important ones are:
A new major release (version 3.0) of my XPLAN_ASH tool is available for download.
In addition to many changes to the way the information is presented and many other smaller changes to functionality there is one major new feature: XPLAN_ASH now also supports S-ASH, the free ASH implementation.
If you run XPLAN_ASH in a S-ASH repository owner schema, it will automatically detect that and adjust accordingly.
XPLAN_ASH was tested against the latest stable version of S-ASH (2.3). There are some minor changes required to that S-ASH release in order to function properly with XPLAN_ASH. Most of them will be included in the next S-ASH release as they really are only minor and don't influence the general S-ASH functionality at all.
Catchy title, huh? :-)
The Snapper v4 is getting ready! I am going to launch it on Wednesday 13 Feb 11am PST at the Snapper V4 webinar (register here).
The major new features include:
Snapper is still a free-to-use tool and it still does NOT require any object creation nor changes in your databases for use. Now even DBMS_LOCK access isn’t needed, although it’s still useful for convenience.
Some years ago I wrote about how sqlplus allows you to run sqlplus scripts directly from HTTP and FTP locations instead of the local filesystem. By the way, I didn’t even notice – my blog is over 5 years old already! :)
I a recent email thread Marco Gralike just showed the simplest way I to open a HTTP URL and download + list its contents in a CLOB datatype. It’s the HTTPURITYPE and its getCLOB (and getBLOB) methods.
I think I’ve finally gotten the blog formatting to be like I want … The syntax highlighter plugins were not good enough as I want very flexible output formatting (not just code snippets, but sqlplus script output) as below:
A new version 2.0 of the XPLAN_ASH utility introduced here is available for download.You can download the latest version here.The change log tracks the following changes:- Access check- Conditional compilation for different database versions- Additional activity summary- Concurrent activity information (what is/was going on at the same time)- Experimental stuff: Additional I/O summary- More pretty printing- Experimental stuff: I/O added to Average Active Session Graph (renamed to Activity Timeline)- Top Execution Plan Lines and Top Activities added to Activity Timeline- Activity Timeline is now also shown for serial execution when TIMELINE option is specified- From 126.96.36.199 on: We get the ACTUAL DOP from the undocumented PX_FLAGS colu
Jagjeet Singh mentioned that he has built a V2 of his cool SQL Dashboard sqlplus-based monitoring script, which now also shows a nice colored ASH graph output. Yes, right inside sqlplus!
I’m happy to announce Enkitec TV which is a video channel/aggregator of some of the coolest stuff we do here at Enkitec. I have uploaded some of my videos there, including the previously unpublished Oracle parameters infrastructure hacking session and Kerry’s & Cary’s E4 Exadata interview is available there as well!
