Increased heap memory per user in ASE 15.7

Hi there,

since we updated to ASE 15.7 we noticed more 'heap memory per user' is required for some DML transactions that ran fine in earlier versions (e.g.15.5).

The error message says: There is insufficient heap memory to allocate 65520 bytes. Please increase configuration parameter 'heap memory per user' or try again when there is less activity on the system.

Following the Sybase docs, heap memory per user should be 3 time the page size, in our case 3*4K. But nearly 64K seems to be a big step.

Does anyone else faced similar behavior in 15.7 or can someone explain why this happens in 15.7 only ?

Some details:

- ASE 15.7 SP100 on RHEL 6 (64bit)

- Java application using jTDS

Thanks

Mat
