JAVA_HEAP_SIZE option [database]

Function 

To limit the memory used by Java applications for a connection.

Allowed values 

Integer

Scope 

Can be set for an individual connection or for the PUBLIC group. Takes effect immediately. DBA permissions are required to set this option for any connection.

Default 

1 000 000

Description 

This option sets the maximum size (in bytes) of the memory that is allocated to Java applications on a per-connection basis. Per-connection memory allocations typically consist of the user's working set of allocated Java variables and Java application stack space.

While a Java application is executing on a connection, the per-connection allocations come out of the fixed cache of the database server, so it is important that a run-away Java application is prevented from using up too much memory.
