Users started reporting some inconsistency on connecting to a database on DB2 9.5 on RHEL 5.I performed an initial check on connecting via Putty, and received an error of not being able to access the table container.
A db2dialog.log snippet revealed:
ZRC=0x8402001E=-2080243682=SQLB_CONTAINER_NOT_ACCESSIBLE "Container not accessible"
I attempted a backup - which failed due to "not being able to write over a read only file".
The problem was resolved by stopping the LinuxSheild 1.6. It appears LinuxSheild 1.6 had been rolled out without the relevant testing. Modifying the exclusion list solved the problem.
