If you do need to start worrying about contention for highly concurrent inserts, you need to investigate the relative benefits and costs of the features that Oracle gives you for avoiding contention. In particular, you need to be careful when there are only a few processes doing all the work.

Reducing Contention in RAC (Freelist Groups)

One of the great things about owning a BlackBerry is that you immediately become a part of a large, worldwide camaraderie of BlackBerry owners. Many BlackBerry owners would be classified as enthusiasts and are part of any number of BlackBerry user groups. These user groups, along with various forums and web sites, serve as great resources for BlackBerry users. Many of these resources are available right from your BlackBerry, and others are web sites that you might want to visit on your computer. Sometimes, you might just want to connect with other BlackBerry enthusiasts, ask a technical question, or keep up with the latest and greatest rumors, apps, and accessories. This chapter gives you some great resources.

Table A-4. XML Doc Comment Reference (Continued)

Another option for reducing contention on tables subject to highly concurrent inserts, particularly for OPS (as it was) and RAC (as it is now) was the option to create a table with multiple freelist groups. The manuals still make some comment about this feature being relevant only to multiple-instance Oracle, but in fact it can be used in single-instance Oracle, where it has an effect similar to setting multiple freelists. (Of the two options, freelists is usually the sensible, and sufficient, one for single-instance Oracle.)

Where to go for more help for anything to do with your BlackBerry: Do a web search for BlackBerry Technical Knowledge Base or BlackBerry Technical Solution Center. One of the top links will usually get you to this page on www.blackberry.com. You may also be able to get directly to the Solution Center by typing in this web address: www.blackberry.com/btsc/. Just type your question in as few words as possible in the Search box in the middle of the screen. The Solution Center may look similar to the image in Figure 36-1.

Multiple freelists, as we saw earlier, reduce contention because each freelist has its own top block, so insertion takes place to multiple table blocks instead of just one block. There is, however, still a point of contention because a freelist starts with a pointer to its top block, and all the pointers are held in the segment header block. When running RAC, even when you have eliminated contention on table blocks by specifying multiple freelists, you may still have an overheated segment header block bouncing around between instances. You can specify multiple freelist groups as part of the specification for a table (see script flg.sql in the online code): storage (freelist groups 5) If you do this (in a non-ASSM tablespace), you get one block per freelist group at the start of the segment, after the segment header block. Each block (group) gets associated with an instance ID, and each block (group) handles an independent set of freelists. So the contention on the segment header is eliminated.

One of the classes recorded in the view v$waitstat is named free list. Given the existence of freelists and freelist groups, the name is a little ambiguous. In fact, this class refers to freelist group blocks. Waits for segment header freelists may be one of the causes when you see waits in the class segment header.
