Troubleshooting
Problem
The DataType is not being correctly replicated across the ImpactServer Cluster
Symptom
The .type file of the Secondary ImpactServer configuration is truncated with the error message:
- Error 500: Mark invalid
Cause
APAR "IZ81446: IMPACT 511 CLUSTER UNABLE TO REPLICATE DATATYPES WITH USERPARMETERS VALUES IN EXCESS OF 16,000 CHARACTERS." [link below]
Resolving The Problem
Additional comments associated with APAR IZ81446 release notes:
"a new property is added to increase the file size limit:
- impact.cluster.readlimit=<size limit>
Add the property to $NCHOME/impact/etc/<SERVERNAME>_server.props file
where size limit can be 8192, 16384, 32768, etc.. "
The property would have to be added to all ImpactServers in the Cluster and would require a restart to enable - ensuring that the ImpactServer started as Primary had the correct, uncorrupted .type file to be replicated across the Cluster. Also ensure that there are no trailing white-space characters on the property as these invalidate properties in lower versions of Impact.
The APAR is not an issue in Impact 6 and 7, but one would still have to include this property with an appropriate value to handle a large character length for the USERPARAMETERS parameter.
The character length includes the whole USERPARAMETERS property name as well as the definition.
For example one would add the property:
- impact.cluster.readlimit=32768
to the files:
- $NCHOME/impact/etc/NCI1_server.props
$NCHOME/impact/etc/NCI2_server.props
where one wished to allow the replication of a DataType between two ImpactServers called NCI1 and NCI2 in a Cluster where the USERPARMETERS property line were 20,000 characters long.
