Issue/Introduction



When I tried to unload our history data from the history files by using the IDB2UIFI utility, the unload job failed with the following error messages. The job failed with RC=8.
DBG73110E DB2S 16:13:06 UNABLE TO COMMUNICATE WITH DATA COLLECTOR. DBSUB=DB2S, D
DBG73117E DB2S 16:13:06 FAILING REQUEST CODE: POSTHIST AND TYPE: TCLOSE
How should I do?

The execution jcl is was follows.

Resolution

The TESTVER parameter in the IDB2UIFI job was specified as the following.
TESTVER=R180  (Because the client uses R18.0, it should be specified as R180. If R19.0 is used, it should be specified as R190.)
However, the TESTVER parameter in the IDDCPARMS member was commented out as follows. (The IDDCPARMS is usually specified in the SYSPARMS DD in the Data Collector.)
* TESTVER=R180

Please see the explanation of the TESTVER parameter in the Reference Guide.
TESTVER=xxxx
Specifies a 1-4 character identifier for a separate unique data collector, which can be started on the same DB2 subsystem as another data collector.
Default: Rxxy, where xx is the version number and y is the release number or space if the release number is zero. For example, r12.0 has a default TESTVER of R12 , r12.1 has a default TESTVER of R121.

Threfore, "R18" was set for the TESTVER vaule of your data collector as the default. (because the TESTVER parameter in their IDDCPRMS was commented out.)

You should do one of the following.
1. Specify the TESTVER=R18 in the IDB2UIFI job and rerun the job.
2. Remove the asterisk(*) for the TESTVER=R180 line in the IDDCPARMS and recycle the data collector and rerun the IDB2UIFI job.

Additional info;
The following parameter values should be synchronized between a data collector and the IDB2UIFI job.
DBSUB, DBLOC, TESTVER
