Summary of PHP compression and archive extensions To open the PHP user manual, we can see the following library of functions for processing compressed files, Bzip2,lzf,phar,rar,zip,zlib So what are the actual application scenarios for each of these, and we'll pick one up next. BZIP2: The official introduction is this: The BZIP2 function is used to transparently read and write bzip2 (. bz2) Compressed files. Self-Understanding as follows: This library

Failure phenomena:Data Guard archive Gap, the tragedy is that the lost archive on the Main library was deleted by Rman Backup, the lost archive about 20, the database size of about 2T, if the Rebuild DG will be very time-consuming, so decided to use incremental backup to recover the DG, the main steps are as follows:1. Backup Repository spfile filesql> create pfi

Prior to the use of archived technology in the project, also used in the MjextensionBut the problem is, this public library encountered some problems can not be archived, so that the egg pain, how to do it.For the parts that cannot be archived, the function is manually archived, very silent.Find out why:Originally for two models, how a inherits B, then A has a big situation is unable to archive!Wrote it myself.For the A model and the B-mode above, the

The size of ipa generated by archive is smaller than that generated by bulid and then dragged to itunes. The size of ipa is 7 and 8 Mb. Cause The archive execution file does not contain debugging information, Xcode first generates the dSym file using the release execution file, then deletes it, and re-generates the archive execution file. You can use the fo

Always feel that using Windows to run Oracle is not reliable thing, can this world there are always a lot of people like to do things like this, for the database more common two things: Rman and delete the DG Standby archive log, on the Linux/unix platform using shell implementation is very simple, But ran to win inside, became vexed, not because of the trouble, but because the use of less people, do not know how to deal with the matter, I wrote a sim

For most Java developers, the JAR file and its "close relatives" WAR and EAR are just the end result of a lengthy Ant or Maven process. The standard step is to copy a JAR to the appropriate location in the server (or, in a few cases, the user machine) and then forget about it. In fact, the jar can do more than just store source code, you should know what the jar can do and how to do it. In this series of 5 events, you will be shown how to maximize the use of Java

If the activity of the database is not very frequent, you can see that its flashback log is relatively small. So what is the way to flashback to the past? The schematic is as follows: 12:50 change data for the first time (100-->200) 1:00 Flashback Log write for the first time. Record content is before the change data: 100 1:10 Se

This extension allows you to read and write the zip archive transparently and the files inside them. After PHP5.2, in order to use these functions, you must use the--enable-zip configuration option to provide zip support when compiling PHP. Example #1 Create a ZIP archive Example #2 output document details and list Example #3 Zip Stream package to read meta information for a OpenOffice file This example

Most people will first check whether the disk space in the archive directory is full and determine whether the archive space is full based on the free space of the archive directory, however, I think this method does not necessarily represent the actual situation. What you see may be a superficial phenomenon. By default, when we create a database in dbca, the

The disk space of the DG slave database is full, leading to the failure to create an archive.Last Friday, I went to a customer to perform database inspection. It was the database of a 10 Gb NC System on Windows 2008 and configured with DG. However, I found the database error during inspection:Tue Nov 11 10:13:57 2014LNS: Standby redo logfile selected for thread 1 sequence 3945 for destination LOG_ARCHIVE_DEST_2Tue Nov 11 10:14:29 2014 Errors in file d: \ oracle \ product \ 10.2.0 \ admin \ nc \

Oracle databases can be run in 2 modes: Archive mode (Archivelog) and non-archive mode (Noarchivelog) 　　 Archiving mode can improve the recoverability of Oracle databases, the production database should run in this mode, the archive mode should be combined with the corresponding backup strategy, only the archive mode

I don't know if there's anything to clean up. A directory history file needs to be cleaned. There will probably be a lot of other places to clean up the history files, which may be used. I spent the past two days writing a script, cleaning more convenient, there will be a large number of historical documents to clean up the words can be used. The commands used in scripts are only Linux, and are not supported like Solaris, so they can only be run on Linux. If it is NAS storage, it can be mounted
