On one of the pages you'll get to check the 'Distributed Polling' option:
Leave it like it is, since it adds the 'SKIP LOCKED' option in the 'FOR UPDATE' clausule.
In my example screendump I set the Database Rows (more...)
Read and monitor Oracle related blogs and news sources, all in one place.
This blog post is inspired on work I have been doing on Standard Edition databases and the returning confusion about what is and what is not part of Standard Edition.
DBA_FEATURE_USAGE_STATISTICS is a tool in determining license usage for the Oracle database. It is good to understand the implications of each entry, know what is happening in your database and thus be able to have a substantial conversation about the usage of your license, being (more...)
In a hectic year it is good to attend and contribute to Oracle user group sessions. This adds an element of a ‘Working Holiday’ to someones schedule. I can promise you, the vacation isle of Rovinj is a perfect venue for this and especially since it is the last week of the opening of the Hotel for this season.
Of course you can find all information about contributing to these events right here!!
I had the pleasure of rebuilding an Exadata rack for a customer a while back, and it provided a pretty good refresher in backup and recovery for me. As DBAs, we back up databases all the time, but the restores are performed much less frequently. In the case of this rack, there were several databases across multiple ASM diskgroups. One of the goals of the rebuild was to consolidate all of the databases into a (more...)
A rather not so great post about an ORA-00600 error i faced on a standby database. Environement was 184.108.40.206 on Sun Super Cluster machine. MRP process was hitting ORA-00600 while trying to apply a specific archive log.
The error message was something like this
MRP0: Background Media Recovery terminated with error 600 Errors in file /u01/app/oracle/product/220.127.116.11/diag/diag/rdbms/xxxprd/xxxprd1/trace/xxxprd1_pr00_6342.trc: ORA-00600: internal error code, arguments: , , , , , , , (more...)
This is no regular bit of work and it will probably (and hopefully) never hit you in a production setup…
The prerequisite is that you know how on-line data replication in general, and Dbvisit Replicate specifically, work.
The following case is true:
I had half of a replication pair running.
It means that the MINE process was running, converting REDO-log in PLOG-format. The APPLY process had not yet started because the target database was (more...)
If you’ve run an exachk report, y0u may have seen the following message with regard to your databases:
|FAIL||Database Check||Database parameter CLUSTER_INTERCONNECTS is NOT set to the recommended value||db01:dbm011, db02:dbm012||View|
This check is commonly seen when a database is created on Exadata without using the custom “Exadata” templates included with the database creation assistant. These customized templates include a multitude of recommended parameter settings found in (more...)
Just a quick note to point out that the October PSU was just released. The database has a few more vulnerabilities than usual (31), but they are mostly related to Java and the high CVSS score of 9 only applies to people running Oracle on windows. (On other operating systems, the highest score is 6.5.)
