With your /etc/security/limits values set unlimited (-1), in Cshell
you might try the following:
dsmc q systeminfo -con osinfo (see values before)
unlimit
dsmc q systeminfo -con osinfo (no change in data segment size?)
setenv LDR_CNTRL MAXDATA=0
dsmc q systeminfo -con osinfo (data segment size now infinite)
Ok, it seems that this a bit more hairy than that.
With LDR_CNTRL set to MAXDATA=0 the systeminfo command says that data
segment size is infinite. Great. But when I try to run the
incremental backup, it fails after 15,000 files! Also, the way it
fails, is somewhat random.
First try:
Fatal error: got signal 11
IOT/Abort trap
Second try:
ANS1030E The operating system refused a TSM request for memory
allocation.
Third try:
Fatal error: got signal 4
IOT/Abort trap
I believe the MAXDATA setting is the number of 256 MB segments and 0
is the default (256 MB).

Well, the naive idea is to set MAXDATA to 0xF00000. But it seems that
8 is the maximum, and the backup fails after using ~ 2 GB, like
before. Maybe I need to use LDR_CNTRL=LARGE_PAGE_DATA=Y or something?
