This forum is for raising questions about the contents of the Concurrency chapter.

database concurrency

Should we use only transactions for database concurrency control, or are we expected to also use locks or Java synchronized? —The preceding unsigned comment was added by 65.95.151.153 (talk) 19:02, 27 February 2007 (UTC).

Transactions are the most reliable and comprehansive way of handling concurrency issues for a database. Locks are suited for controlling access to simple objects such as files. Java synchronized is best for mediating access to a shared data object within a Java class. --C09notes 19:17, 27 February 2007 (UTC)

File permission problem with File:Dom-css2-browser.PNG

Thanks for uploading File:Dom-css2-browser.PNG. I noticed that while you provided a valid copyright licensing tag, there is no proof that the creator of the file agreed to license it under the given license.

If you created this media entirely yourself but have previously published it elsewhere (especially online), please either

• make a note permitting reuse under the CC-BY-SA or another acceptable free license (see this list) at the site of the original publication; or
• Send an email from an address associated with the original publication to permissions-enwikimedia.org, stating your ownership of the material and your intention to publish it under a free license. You can find a sample permission letter here.

If you did not create it entirely yourself, please ask the person who created the file to take one of the two steps listed above, or if the owner of the file has already given their permission to you via email, please forward that email to permissions-enwikimedia.org.

If you believe the media meets the criteria at Wikipedia:Non-free content, use a tag such as {{non-free fair use in|article name}} or one of the other tags listed at Wikipedia:Image copyright tags#Fair use, and add a rationale justifying the file's use on the article or articles where it is included. See Wikipedia:Image copyright tags for the full list of copyright tags that you can use.

If you have uploaded other files, consider checking that you have provided evidence that their copyright owners have agreed to license their works under the tags you supplied, too. You can find a list of files you have uploaded by following this link. Files lacking evidence of permission may be deleted one week after they have been tagged, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you. MBisanz ^talk 05:13, 7 January 2010 (UTC)

Notification of automated file description generation

Your upload of File:Conc-wd-dep2.PNG or contribution to its description is noted, and thanks (even if belatedly) for your contribution. In order to help make better use of the media, an attempt has been made by an automated process to identify and add certain information to the media's description page.

This notification is placed on your talk page because a bot has identified you either as the uploader of the file, or as a contributor to its metadata. It would be appreciated if you could carefully review the information the bot added. To opt out of these notifications, please follow the instructions here. Thanks!
