Generally, backup is required at the operating system level. One of the most common backup methods for an operating system is mirroring. In practice, generally, the volume group rootvg is used as an image. Check whether rootvg has been mirrored: 1) lsvg-o 2) lsvg-l rootvg # Lsvg-l rootvgRootvg:Lv name type LPs PPs PVs LV STATE MOUNT POINTHd5 boot 1 2 2 closed/syncd N/Hd6 paging 16 32 2 open/syncd N/Hd8 jfs2log 1 2 2 open/syncd N/Hd4 jfs2 12 24 2 ope

Recently, compare the query performance of xpath and JCR-SQL2 in jackrabbit, although JCR no longer recommends the use of xpath from version 2.0, but in terms of the query performance, XPath seems much higher than the JCR-SQL2 The following are the comparison results. Test environment: Jackrabbit 2.2.7 Windows 2003 4 GB memory AMD athlon (TM) II X4 640 3.01 GHz processor Data source: 1033 node records, including 917 files and 116 folders Query comparison: Test records JCR-SQL2 (MS)

1521 (Oracle also officially registered two new ports 2483 and 2484, maybe the new version may be the default port number after it is released, among them, 2484 is used for SSL connections. Almost all scanners can directly scan whether the port is opened. If it is set to an uncommon port number, it may give an illusion, even if the port is opened, You need to guess what service the port is running, which m

concept of scope is similar to that in other languages. Each time a function is called, it enters the scope of a function. After the function is returned, returns the scope before the call. The syntax style of JS is similar to that of C/C ++, but the implementation of the scope is different from that of C/C ++. Instead of using the "stack" method, the list is used, the procedure is as follows (as described in ecma262 ):The scope of any execution context is implemented by the scope chain.When a
