DB2 8.1 db2cc DB2JAVIT : RC = 11 Error // SuSE 9.0 Kernel 2.4.25

Data Goob

I searched far and wide for more information on how to correct this
problem, but did not find any information on what to do.

We have successfully installed DB2 8.1 on Linux.

SuSE 9.0.
Kernel 2.4.25
Dell PowerEdge 6650
Filesystem jfs

DB2 software installed perfectly as root, but cannot run db2cc when
becoming db2inst1.

We get the following error:

DB2JAVIT : RC = 11

We do have Sun's Java installed. We did a search in YaST2 and found
the java2-jre installed version 1.4.2-35
URL ( http://java.sun.com/j2se/1.3/download-linux.html )
RPM ( java2-jre-1.4.2-35.i586.rpm )

We also have installed java2-jre-1.4.2-35.i586.rpm, which is the GNU
runtime library for gcc.
This is the only Java RPM we have installed outside of IBM's Java
software. Yast reports IBMJava2-1.3.1, Java Help, Java Support, Java
Common files installed, from the DB2 installation.
Environment:

Before you suggest things, we unset all JAVA_ related env vars as root
before installing, and everything went real smooth, and successfully
installed, and the engine is up and running, no problems. We just can't
get the db2cc running. We installed DB2 before with db2cc running on
another server, but can't seem to debug why it doesn't work on this one.

Your help would be greatly appreciated. Please post to the group as I
can't always get to netscape.

Peter,

Although that may work, I'm not sure that "pretending" to be a 2.2 kernel is
the best answer.

Alternatively, try the workarounds for Red Hat Enterprise Linux 3 in the
"Errata" on the "Validation" page -

http://www-306.ibm.com/software/data...dfs/errata.pdf

Java versions used by DB2 are very specific (not only does the system expect
you to have the IBM JDK, but also a specific version of it).

One of the things I've noticed is that if you have a Sun JDK newer than the
IBM JDK supplied with DB2 then the install will fail. You have, as per the
doc above, to ensure that the Sun JDK isn't found during the install. You
also have to, after the install, set DBM CFG parameter JDK_PATH to point to
the IBM JDK.

This is really a shot in the dark, but could you try removing the -l option
in sqllib/db2cc?
The '-l' option is a single JVM option but it didn't work on UNIX before
FP4. With FP4, the option has been fixed but it might never have been tried
on SuSE 9, so you should probably report this to service.

For what it's worth, db2cc is now working, and here's my env:

db2inst1@xxxxxx:~> cat sqllib/userprofile
PATH=/db2home/db2inst1/bin
PATH=$PATH:/db2home/db2inst1/sqllib/bin
PATH=$PATH:/db2home/db2inst1/sqllib/adm
PATH=$PATH:/db2home/db2inst1/sqllib/misc
PATH=$PATH:/usr/local/bin
PATH=$PATH:/usr/bin
PATH=$PATH:/usr/X11R6/bin
PATH=$PATH:/bin
PATH=$PATH:/opt/gnome/bin
PATH=$PATH:/opt/kde3/bin
export PATH
# unset JAVA_BINDIR
# unset JAVA_HOME
# unset JAVA_ROOT
# unset JRE_HOME
export LD_ASSUME_KERNEL=2.2.5

You'll notice I had previously tried to unset the JAVA_ vars but it had
no effect. The LD_ASSUME_KERNEL=2.2.5 did the trick, and we're on the
air. But I do agree that we should be pointing to the right JDK. The
biggest problem as everyone knows is that every time a java application
is installed it seems like I need yet another version of the JDK that
somebody made just for their software.

"Java, write once, run everywhere but be sure to use our version of the JDK"

If you have some specific vars I should be using for IBM DB2 please let
me know, otherwise it appears to be working correctly. We'll also be
applying the FixPacks shortly.

Thanks!

FYI: The reason why db2cc did not work without LD_ASSUME_KERNEL=2.2.5 is
a floating stack feature of the glibc which is incompatible with
some JDKs. Unfortunately, this feature ist enabled in the SuSE 9.0
distribution (SuSE 8.2 would work).
By setting LD_ASSUME_KERNEL=2.2.5 you disable this floating stack feature.

I'm very curious about these. Why are you clearing out the PATH, only
to reset it to include what dbprofile has? What would happen if IBM
changed db2profile to add another directory to your PATH?

at your own risk.

DB2 doesn't need one made just for it - but it is only validated
against certain JVMs.

JDK"
Yes, something like that. Problem is that the JVMs aren't really as
compatable with each other as some would like ;-)

You're right, we had DB2 running with no problems on an 8.2 system. We're
about to rebuild that system shortly so it'll be 9.0 before too long.

So...We got that problem solved, but then had problems with clustering, which
we then figured out were NFS issues. We have two 9.0 systems we are clustering
as MPP, with node A being the NFS server, and then n-servers as clients mounting
a /db2home directory. Strange thing about NFS on SuSE 9.0, node B could mount and
see and use the /db2home on node A, but kept getting the SQL6048N error. It was
figured out by Toronto Tech Support, we hadn't started rpcd.statd, even though it
appears it wasn't really necessary--to my mind at least--and we didn't catch that
we needed rpc.statd in any documentation. But now things are working, and hopefully
we will be smokin' shortly with a lot of data. ( I have to say that the nuts-b-bolts
aspects of DB2 are becoming more appealing over time. Hopefully my enthusiasm will
be rewarded, keep your fingers crossed! ) I'm not too thrilled that we have to use
the r-commands to make things work, there should be a better way than rlogin, etc.
