I installed DB2 luW 11.5 on RHEL KVM and facing issues with operations. The install itself is going through without any issues, and I am able to create a DB2 Instance. First explicit connection to the instance with password locks up the server / instance with db2sysc hitting 100% CPU. There is nothing on the diaglog (with diaglevel 4) or any other linux logs. Below are the sequence of steps.
a) Installed all necessary pre-requisites - basically just 32
bit pam and libstdc++ libraries
b) Installed db2 data server - no purescale
c) create ese db2inst1 instance (no database yet)
d) "Db2 attach to db2inst1" - works perfectly.
e) "db2 attach to db2inst1 user db2inst1 using xxxxxx" - hangs indefinitely
Local users, no fancy ldap, sssd etc. No SSL. My Host OS is RHEL 8.2 with all the latest updates. I tried the below guests with the same results.
a) Rhel 8.2 (I realized that this is not in the supported OS
list for DB2 Luw 11.5 )
b) RHEL 7.5
c) centOS 7.5
My hunch is, there is something on the new host kernel (4.18) that is making db2 slip. While i understand i am trying something that may not be fully supported yet (rhel 8), I am looking for any workarounds to make this work. I was hoping to keep the guest at a supported version, but it is not working, as such.
I am trying hard not to degrade my RHEL to a 7.x version with a 3.10 kernel as I was hoping DB2 will bring support to rhel 8 sometime very soon.
