Administering CDS

 

Known CDS Problems

 

Resource Problems

 

It is important to configure sufficient resources for DCE according to the

 

instructions in this manual. CDS can fail if a CDS server or client system

 

runs out of system resources such as swap space, disk space, or kernel

 

resources. Symptoms usually include a cdsadv or cdsd crash with one of

 

a variety of error messages (which may not directly indicate the source of

 

the problem.)

 

If a CDS problem is linked to a shortage of resources, stop DCE, free or

 

configure more resources, and then restart DCE to bring the node back

 

on-line in the cell.

 

Clock Reversal Problems

 

Timestamps are used in the CDS database to establish the order of

CAUTION

 

events in changes to the name space. If the date/time on a DCE node is

 

manually set backward more than a few minutes, the CDS database can

 

become corrupted, crashing cdsd, and leaving the cell unusable. This is

 

unrecoverable unless you have a recent backup. It is therefore

 

imperative that manual clock resetting be avoided on DCE nodes.
