11.2.0.3 v$sqlstats.last_active_time stops changing and breaks AWR | Nigel Noble's Oracle Blog
https://nigelnoble.wordpress.com/2013/03/28/11-2-0-3-vsqlstats-last_active_time-stops-changing-and-breaks-awr
Nigel Noble's Oracle Blog. 11203 v$sqlstats.last active time stops changing and breaks AWR. 8212; Nigel Noble @ 3:18 pm. 8221;…. I thought! Well, I recently discovered that any time a sql statement drops off the 3rd party monitoring tool…… IT STOPS BEING MONITORED IN AWR’s DBA HIST SQLSTAT table as well. Let’s start at the very beginning…. V$sqlstats.last active time can stop changing with multiple child cursors. I wrote the following script to compare v$sqlstats to v$sql. Output looks like this:.

“enq: TX – contention” on SELECT with a large buffer cache and 2PC | Nigel Noble's Oracle Blog
https://nigelnoble.wordpress.com/2013/07/12/enq-tx-contention-on-select-with-a-large-buffer-cache-and-2pc
Nigel Noble's Oracle Blog. Enq: TX contention on SELECT with a large buffer cache and 2PC. 8212; Nigel Noble @ 12:08 pm. Note: The following is based on testing with 11.2.0.3 (I believe same issue exists within other Oracle versions). A new variation of “enq: TX – contention”. Our application had the following profile on TWO separate databases:. The Batch Job on DB1. UK DB 1: Starts a transaction. UK DB 1: Updates lot of data in local tables. UK DB 2: returns control back to DB1. UK DB 2: running a criti...
10.2.0.5 dbms_sql leaks memory AND performance degrades | Nigel Noble's Oracle Blog
https://nigelnoble.wordpress.com/2011/01/11/10-2-0-5-dbms_sql-leaks-memory-and-performance-degrades
Nigel Noble's Oracle Blog. 10205 dbms sql leaks memory AND performance degrades. 8212; Nigel Noble @ 11:24 am. We applied the patch for 10269717 and the PGA memory leak was resolved but more importantly the performance remained constant. I just checked the 10.2.0.5 known issues document and this does now list the bug, but it still only references the leak and not the performance implications. 4 Comments ». Thank You for sharing such vital information. This is really useful to me. Comment by Vega Lin.

Nigel Noble's Oracle Blog. 8212; Nigel Noble @ 4:19 pm. The company where I work run a large web infrastructure with many different Java based applications and servers. Most of these application servers connect to the database using a connection pool to manage database connections and reduce the cost of starting/destroying database sessions. Over the years we have spent a lot of time trying to get the right balance to keep session usage as smooth as possible. Maximum connections in the pool set too low?
dbms_scheduler.drop_job “leaks” PGA memory | Nigel Noble's Oracle Blog

Nigel Noble's Oracle Blog. Dbms scheduler.drop job “leaks” PGA memory. 8212; Nigel Noble @ 1:00 pm. I thought I would post a very short note about a recent PGA memory “leak” issue we found in one of our applications that appears to exist in Oracle versions 10gR2 through to 11gR2. I would not expect the problem to actually affect many sites so I am not going to spend a huge amount of time showing the test case but thought I would make people aware of the potential issue.

https://jarneil.wordpress.com/2014/04/07/oracle-asm-12c-new-features
The thoughts of Jason Arneil. Oracle ASM 12c: New Features. Last week I was lucky enough to be presenting at the UKOUG AIM SIG. There was a decent enough crowd in attendance and there were some really interesting talks and some really good speakers. In particularly I found Chris Lawless speaking on replication a particularly engaging speaker, and Dave Webster. Really held the audiences attention late in day. For clearest understanding, you probably want to download the ppt. April 7, 2014. Oracle 12.1...

https://nigelnoble.wordpress.com/2010/07/05/10-2-0-5-keep-pool-serial-direct-read
Nigel Noble's Oracle Blog. 10205, KEEP pool / Serial Direct Read. Filed under: 10.2.0.5. 8212; Nigel Noble @ 11:36 am. Jonathan Lewis made reference to a 11g bug related to using a KEEP POOL in his note Not KEEPing. Oracle 11g introduced a new feature called adaptive serial direct path reads. The 10.2.0.5 patchset has also back-ported. The same direct read feature which is new to 11g although I don’t know if the rules are the same as 11g. The site where I work makes significant use of KEEP pool...I want ...

10gR2 – 11gR2, ASSM Space Management “Bug” | Nigel Noble's Oracle Blog
https://nigelnoble.wordpress.com/2010/07/23/10gr2-11gr2-assm-space-management-bug
Nigel Noble's Oracle Blog. 10gR2 – 11gR2, ASSM Space Management “Bug”. 8212; Nigel Noble @ 10:59 am. ASSM (Automatic Segment Space Management) has an issue when trying to re-use “deleted” space created by another session. There is a very specific set of circumstances. Which must occur for this issue to show itself, but will result in tables (and I suspect indexes) growing significantly larger. The conditions required to cause the issue. What we found was the INSERT statement could not. 5 Comments ».

Another daughter to love
Another daughter to love. Monday, March 28, 2011. Friday, February 11, 2011. Maybe she needs a liver ultrasound or scan? I was stressed, stunned, and crying a few days ago about this. Just start up treatment again soon and keep praying. Her thyroid came back high as well this lab. this level fluctuates between high and normal every other lab, normal, high, normal, high, etc. I got an appt for Julia March 9. Always something. Tuesday, January 25, 2011. Better than planning a party, and easier.
