Hi how can i increase my parameter values in my system

Question

Dear Experts ,
here my functional consultants gets below shotdump and how can i solve that an error
Runtime Errors         TSV_TNEW_BLOCKS_NO_ROLL_MEMORY
Short text
    No roll storage space of length 1802248 available for internal storage.
hat can you do?
   Try to find out (e.g. by targetted data selection) whether the
   transaction will run with less main memory.
   If there is a temporary bottleneck, execute the transaction again.
   If the error persists, ask your system administrator to check the
   following profile parameters:
   o  ztta/roll_area            (1.000.000 - 15.000.000)
          Classic roll area per user and internal mode
          usual amount of roll area per user and internal mode
   o  ztta/roll_extension       (10.000.000 - 500.000.000)
          Amount of memory per user in extended memory (EM)
   o  abap/heap_area_total      (100.000.000 - 1.500.000.000)
          Amount of memory (malloc) for all users of an application
          server. If several background processes are running on
          one server, temporary bottlenecks may occur.
          Of course, the amount of memory (in bytes) must also be
          available on the machine (main memory or file system swap).
          Caution:
          The operating system must be set up so that there is also
          enough memory for each process. Usually, the maximum address
          space is too small.
          Ask your hardware manufacturer or your competence center
          about this.
          In this case, consult your hardware vendor
   abap/heap_area_dia:        (10.000.000 - 1.000.000.000)
          Restriction of memory allocated to the heap with malloc
          for each dialog process.
   Parameters for background processes:
   abap/heap_area_nondia:        (10.000.000 - 1.000.000.000)
          Restriction of memory allocated to the heap with malloc
          for each background process.
   Other memory-relevant parameters are:
   em/initial_size_MB:         (35-1200)
          Extended memory area from which all users of an
          application server can satisfy their memory requirement.
   Note which actions and input led to the error.
   For further help in handling the problem, contact your SAP administrator
   You can use the ABAP dump analysis transaction ST22 to view and manage
   termination messages, in particular for long term reference.
how much can i increase please suggest me
Regards

Answer 1

hih mark,
for what base i can increase my parameter values
presently in my parameter values are recomended valus
Parameter          present value          Recommended values
ztta/roll_area-           6500000                      (1.000.000-15.000.000)
ztta/roll_extension-      2000683008          (10.000.000-500.000.000)
abap/heap_area_total u2013 2000683008            (100.000.000-1.500.000.000)
abap/heap_area_dia u2013 2000683008          (10.000.000-1.000.000.000)
abap/heap_area_nondia u2013 2000683008           (10.000.000-1.000.000.000)
em/initial_size_MB u2013           4092                (35-1200)
how much can i increase
