Did you see any error message in $SPECROOT/SS/DDM/ARCHMGR.OUT?

Is the new system in production already?

There are two paths you can take:

1.       Re-import Ddmdb after optimizing (might cut down size a little bit - 
if not already done else try second path if it is an option)

a.       On the existing Spectrum server run maintenance scripts for ddm - 
db_optimize.pl and db_maintenance.pl (See Database guide)

b.      Create checksum for the file, transfer to destination and verify 
checksum on the destination (I have seen corruptions in transferring a single 
big file).

c.       Load it again and keep eye on ARCHMGR.OUT.

2.       Re-install new server (if this is an option)

a.       Un-install existing installation.

b.      On the existing Spectrum server run maintenance scripts for ddm - 
db_optimize.pl and db_maintenance.pl (See Database guide)

c.       Create checksum for the file, transfer to destination and verify 
checksum on the destination (I have seen corruptions in transferring a single 
big file).

d.      Refer to migrate and upgrade section (chapter 3 in the Installation 
guide)

e.      Create directory structure for DDMdb and then do the install.

Subject: [spectrum] Long ArchMgr start with huge DDM DB

Hi all,

after importing (via ddm_load) a rather huge DDMdb (about 25 gig, make with 
ddm_save under SPECTRUM 9.2.2H9) into a fresh 9.2.2H9 installation on another 
hardware (same IP, same hostname, same LH, same landscape name), first ArchMgr 
start hangs with "ArchMgr validating database" for at least 20 minutes without 
mysqld or ArchMgr consuming significant CPU resources.

Our SPECTRUM partner advises me to give it at least 30 minutes, just wanted to 
check if anyone has experiences with moving DDM-Dbs that big from one machine 
to another - and especially what happens when you start ArchMgr for the first 
time. I mean, the database files are there, there is nothing obvious ArchMgr 
has to do compared to an installation that had this DDM DB already up - so what 
takes that long or do I have a problem?

Freundliche Grüße / Best regards
