Case:

During Client import you get an error something like that:

No main memory available (42500000)

twrtab reached memory limit; memory usage 42000000

139596 entries from INDTEXT (DISR %) deleted.

Solution:

Providing more memory for Rtrans,  try to reimport at operating system level with following command:

tp import <TR> <SID> clientxxx “-Dr3transoptions=tcs=200000000”  pf=TP_DOMAIN_SID.PFL

If needed with more u options:

tp import <TR> <SID> clientxxx “-Dr3transoptions=tcs=200000000”  u01268 pf=TP_DOMAIN_SID.PFL
