DataType incorrect on Secondary

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.
