I have a problem with DB2 8.2 on AIX 5.3, I am no longer able to start the database.

db2 was running since 1 year without problems, but since it was recently run out of space I am no longer to start it.
I even completly reinstalled db2 8.1 + FP13 but the problem still exist.

The error message I receive seems to multi partitioned releated but I just have a single partition installation.

When I run dbstart as the instance owner, I get the following error:

0 0 SQL6048N A communication error occurred during START or STOP DATABASE MANAGER processing.
SQL1032N No start database manager command was issued. SQLSTATE=5701


The db2diag.log looks like this:

I can run the db2 shell without problems, i can get and update the dbm configuration, loopback is resolved as commonly as 172.0.0.1 and pingable

Any Ideas what's the cause is?
Haven't found a solution yet.
Thanks in adavnce

can you check db2nodes.cfg file
this file is being used for detecting the nodes/hosts

The nodes.cfg was looking good.

0 hostname 0

But the loopback error was conncerning me, so I took a look to my /etc/hosts file and noticed that the 127.0.0.1 adress was before the main IP adress.

After changing this I get the same error in db2diag.log, but this time I was receiving the real hostname in the error.

So I just following stupd the instructions to allow remote exectuions:
http://publib.boulder.ibm.com/infoce...6f%73%74%22%20

Which was fixing the issue

But I wonder why this had nnot to be done after the initial setup before a hlaf year???

what about the DAS server is it running ? Did you do netstat -na | grep <port#>, is the port that db2 uses still LISTEN, TIME_WAIT or CLOSE_WAIT mode ? What is the timeout value of a TCP connection on AIX
