OutOfMemory getNewTla occurred in production environment.
When looking into the heapdump at OutOfMemory, the suspicion is that com.splwg.base.support.scripting.PreparedXQueryCache$CacheAssoc is needed to be decrease, because heap histogram shows that PreparedXQueryCache is the one of the biggest class which seems to be used on Thread Local Area.
Steps to replicate
-------------------------
1. According to Doc 1980997.1 when OOM referencing PrepareQueryCache, the following changes/additions should be made in spl.properties:
com.oracle.XPath.LRUSize=2000
com.oracle.XPath.flushTimeout=86400
2. Check for OOM errors
3. Onsite these default values seem not to be sufficient.
