Close all SQL anywhere and adaptive Server Anywhere database servers because version 10 of the uninstall utility is not available for the running database. For example:

single command Listing 1 demonstrates one of the most common UNIX bad habits: defining a directory tree at a time. Listing 1. Bad habits 1 Example: define each directory tree separately ~ $ Mkdir TMP~ $ CD TMP~ /Tmp $ mkdir~ /Tmp $ CD~ /Tmp/A $ mkdir B~ /Tmp/A $ CD B~ /Tmp/a/B/$ mkdir C~ /Tmp/a/B/$ CD C~ /Tmp/A/B/C $ Using the-P option of mkdir and creating all parent directories and Their subdirectories in a single command is much easier. However, even for administrators who know this o

alert_oracle.log file and found many error messages. Here, this problem has taught me a lesson: oracle-related operations will certainly write logs to the alert_oracle.log file as long as there is a problem, check whether you are aware of this log file. After checking the information on the Internet, I learned that Oracle 10 Gb archive logs are stored in the Flash recovery area by default. For me, E: /oracle/product/10.2.0/flash_recovery_area/ORACLE/

An integer literal is expressed in decimal (base), hexadecimal (base), octal (base 8) , or binary (base 2).int decimal = ten; int hexadecimal = 0x10; int octal = 010; = "Ten"; System.out.println (decimal); // Ten SYSTEM.OUT.PRINTLN (hexadecimal); // - System.out.println (octal); // 8 // 2Hex starts with 0xOctal starts with 0No binary numb

In the performance testing, we often refer to a number of indicators and standards, today to share a more popular industry "2-5-10 principle."The specific statement can be attributed to the following 4:1. When the user is able to 2 when the response is received, the response of the system will be felt quickly.2. When t
