The following article describes the suspension of DB2 diag during the parallel LOAD Operation of DB2. log shows the DIA8533C error. If you encounter a similar situation in the actual operation, but you do not know how to solve it correctly, so the following articles must be good teachers and friends for you.
Product: DB2 UDB ESE
Platform: HPUX 11
Version: V8
Problem description:
On the HPUX operating system, a physical machine has multiple logical

A netizen's database is deployed in a windows environment. It may be due to storage problems or windows file system problems. After I/O problems occur, the database cannot be started after it is restarted, when an error is reported, several files cannot be read. The alert log is as follows:Nov 14 12:33:12 2014Errors in file d: \ oracle \ diag \ rdbms \ orcl \ trace \ orcl_m0000001704.trc (incident = 60577 ):ORA-00700: soft internal error, argument
