In this article, we will focus on the differences between Linux kernel 2.4 and 2.6 in POWER.

Some Cl commands do not produce an OUTFILE like the command in Example 4-99 does.
However, please allow you to spool the output. In this section, we show how to process
Results of a command that produces a spool file. First, we create a program on the iseries
Host that copies a spool file into a database file. Then we show an example that callthe
Dspautusr to generate a spool file, callthe program to copy the spool file into a database
File, and reads
myschema. myfile use the second Member, member2.
Example 4-98 using ovrdbf to access the second member of a multi-member File
Rc = callpgm ("ovrdbf file (myfile) tofile (myschema/myfile) MBR (member2) ovrscope (* job )",
CN );
// Now a select * From myschema. myfile will access member member2
Cmd. commandtext = "select * From myschema. myfile ";
Idb2datareader DR = cmd. executereader ();
// Etc.

Using Cl commands provide an option to store the comm
Brief introduction
When people consider parallel processing in the database engine, they immediately think of an improved query response time by using multiple processors to process a single query. It is often not noticed that parallel processing can also speed up index processing, thereby improving the overall performance of the database server. Using the Ibm®db2®universal database™ (UDB) for iseries™, it is possible to use multiple CPUs for index p
In our example, account is a single table operation.
The preceding essays have generated the accountdataset accountdatatable accountentity accountrule accountsystem class.
So I will not repeat it here.
If you do not want to do this, you can download the Demo code directly.
Create a new winform named testsingletable. CS.
And draw the interface as follows.
Here I am lazy and pull accountdataset to the screen as the data source of the screen's gridview.
1. Add on using
Using wildfish. Data.
The previous method was very stupid. It was to concatenate each field into a string using the | method.In fact, only now can we find that we can use runsqlstmt to run this SQL statement and then output it to a spool file.The following is the idea:1.
1. Create a physical file
Direct operations in strseu or navigator are recommended.
2. Create a primary key for a physical file
Navigator is recommended.
3. Logging physical files
In strjrnpf or in navigator, select the table and log record,
1. External Storage Process-think this is better and can save the encapsulated RPG or CL
Program . The efficiency is also significant,
After all, it is direct Io.
It is relatively simple to bind Cl. sqlrpg hasn't done it yet. Some people know it,
The
1. The host v5r4, that is, the I5 machine, has a function row_number ()-this is not verified because its host environment is v5r3.

UI interface is completely different, then upload the logic and interface to write the dead, encounter different situations need targeted transformation. For a single case, of course, the lightest, only to consider the current situation, not the function can be completely thrown away, can be the most streamlined, but not easy to reuse. If a wheel cannot be reused, it certainly cannot be counted as a qualified wheel. Be aware of this, and now that you have embarked on the road of making wheels,

Android associated source code support-v4, v7, v13 source code, support-v4v13
In the actual development process of Android, you will often encounter the use of v4, v7 or v13 compatible packages, such as ViewPager, Fargment, but cannot be associated with the source code.
There are a lot of solutions on the Internet. Here we will only introduce a small series that have passed the test. I hope it will help you
