Oracle tune v $ UNDOSTAT a 11g database running on an 18-touch AIX database. During the check, it is found that the data in view V $ UNDOSTAT is very strange, 1st records have never been cut. the start time is 09:52:08 and the end time is 15:20:34. Of course, no records are recorded in the archive table. Under normal circumstances, the view should be filled with data for less than 10 minutes, lasting for four days, that is, 6*24*4 = 576 records, and t

IOS Performance Tuning series: Use Time Profiler to discover performance bottlenecks and tune profiler Hardware wide: The fifth article in the IOS Performance Tuning series, which is expected to be updated continuously over 20 articles. The last four articles focus on memory and Analyze memory leakage, zombie objects, and memory allocation. This article introduces the use of Time Profiler to start a true "performance" Tuning journey. Time Profiler als

The first article introduces Analyze's static analysis of the App, which can detect memory leaks in the App. If some memory leaks cannot be solved through static analysis, it can be found through dynamic analysis, the analysis is more targeted.

Android from hardware to application: Step by Step 4-use the JNI method to tune the hardware driver In Android, java applications call the hardware abstraction layer module through the JNI method, from hardware to application in Android: Step by Step 3 -- access the hardware driver in the Hardware Abstraction Layer We have compiled the hardware abstraction layer module. Next we will begin to compile the jni method for the hal layer to provide services

It is very useful for us to realize that Samba can share files with Linux and Windows machines. Here are a few practices to learn about Samba, note: Before you practice, check if Selinux is off or it might not be successful.Practice 1Requirements: Share a directory, anyone can access, that is, without entering a password to access, require read-onlyOpen the Samba configuration file in the [Global] sectionVim/etc/samba/smb.confChange to Security = ShareChange to Workgroup = WorkgroupThen add the
