| Would you be able to share real-life experience with setting
| underscore parameter
| _kgl_version_count to value more than 31? This parameter controls
| number of
| child latches for library cache latch.
|
| It is recommend to increase the value of _kgl_latch_count if instance
| experiences issues
| with library cache, for example:
|
| http://www.ixora.com.au/q+a/library.htm
|
| However Metalink Note 420308.1 states that as a result of bug 5508574
| the instance may hang if the value of parameter is more than 31.
|
| We are looking at increasing value of this parameter for database
| running on
| server with 24 CPU. Default value of the parameter is 29 (next prime
| number after CPU count).

Do you see that your referenced page has 10 years old? Don't you think Oracle rdbms engine evolved during this time?
