There is an omnirc setting we strongly recommend for Data Protector (DP) Cell Managers (CM) where ECC (Encrypted Control Communication) is implemented...
OB2_DNSTIMEOUT=2
It changes the OB2_DNSTIMEOUT value from the default to 3 (we count 0, 1, 2).
It is the number of dns lookup attempts for every client. The default is 30.
With 30 attempts per client, and ECC, we often see strange performance problems, timeouts, or hangs of crs, or bsm.
If the CM can not lookup a client in 3 attempts, there is little advantage in proceeding with an extra 27 tries.
In fact the extra lookup attempts can cause problems.
For this reason please set OB2_DNSTIMEOUT=2 in the omnirc file of all Cell Managers using ECC.
The omnirc (.omnirc on unix) file, by default, can be found as follows...
\ProgramData\OmniBack\omnirc - Windows 2008 and later
/opt/omni/.omnirc - unix systems
The omnirc does not exist by default.
If it is required, make the file by copying omnirc.tmpl (or .omnirc.TMPL) found in the same directory.
