cannot allocate new log&Private strand flush not complete
There are two Oracle10g(10.2.0.5) Database running on SUN M5000(SPARC64 VII 2.53 GHz Quad-Core Processors*4/32GB Memory).
The first Oracle10g DB is running with 8GB SGA and 1GB PGA, the second Oracle10g DB is runing with 7GB SGA and 2GB PGA.
We encountered a issue on the second Oracle DB. When we manually switch the online redo logs with an alter system command as below.
SQL> alter system switch logfile;
The Alert log will display the following messages:
Thread 1 cannot allocate new log, sequence xxx
Private strand flush not complete .
All other Oracle10g DB will not occur "Private strand flush not complete" messages except for the second Oracle10g DB. I want to know the detail reason.
I also saw two Doc ID:[ID 372557.1] and [ID 435887.1] from Oracle Metalink. But I am not satisfacted with what they wrote.
My last target to resolve the issue.
Anyone help me ?
