This framework process is slow, in hours.The problem with bulk pipelines is that usually we don't
. if the MAXSIZE clause is specified for an auto-extending undo tablespace, when the maximum size is reached, the database may begin to overwrite unexpired undo information.
When undo is automatically extended, oracle will try its best to ensure the undo retention time set by undo_retention. When undo space is insufficient, oracle will automatically expand the undo tablespace first, instead of overwriting undo information that has not expired, if the maxsize parameter is set for undo
These days the installation of the CentOS 6 virtual machine always prompts the file system full, at first it was assumed that the recent Oracle operation of large data volumes caused an infinite expansion of the undo TBS, and later found that the NFS cache Management Pack CACHEFILESD problem.

5. Custom tablespace
For index fields, indexes are created in the tablespace set by settings ult_index_tablespace in settings by default. You can specify indexes by specifying the db_tablespace attribute of the field, as shown in figurePublish_date = models. datefield (db_index = true, db_tablespace = 'another _ TBS ')For the model class, use the db_tablespace attribute in Meta to
have at least two 1 Gbps network interface controllers (NICS ). Since the throughput of most hard drive is about 100 MB/s, your Nic should be able to handle disk traffic on the OSD host. We recommend that you use at least two NICs as the public network and one as the cluster network. The cluster network (preferably not connected to the Internet) processes data replication and helps prevent denial-of-service attacks (preventing PG in active + clean status from replicating data across clusters ).

In the above example, the output result is a

You do not need to set storage parameters for each segment. In the same version,
C # determine whether a user uses a browser and display the actual content or QR code accordingly,
When we look at some webpages, we will find such a feature: some pages can only be accessed in, if accessed on a computer, only the QR code of the current address is displayed. How to implement this using C? Let's take a look at the code.
First, we need to determine which browser the user is using, which requires Request. the UserAgent attribute. The difference is discovered by capturing the UserAg

. Pursue Perfection
Why should I mark him as a shortcoming? Imagine if something perfect exists? The pursuit of perfection is often easy to bring people into an extreme demand. I advocate the pursuit of beauty, but the method is based on a measurement. After this measurement, it will make all the members of the team very uncomfortable. It is like a person who wants to learn hygiene from an early age and wash his hands before and after meals, but if a person keeps washing his hands all day long,
CSS style in skin to re-design the pjblog interface. In addition, it is very convenient to combine DIV layout with js for webpage special effects, which gives a lot of creativity. The other is that DIV complies with W3C standards, and no one wants to make their own website in such a browser. It looks like another browser. I used to deploy the network in TBS. The website in ie is displayed normally, and the layout changed to maxthon is messy.Of course
