With OPTIONS(32) set in the CA Top Secret parameter file, the following is seen in the TSSUTIL report:
*08*-04 USS RESOURCE TYPE & NAME : USSLOG CHECK_PRIVILEGE
*08*-2C USS S003011 RESOURCE TYPE & NAME : USSLOG R_DATALIB
For the *08*-04 with CHECK_PRIVILEGE, USS is issuing a check_priv check, which checks to see if the user has UID(0). It is a common check done by USS. The reason why this call is made would have to be explained by USS support.
The *08*-2C on the R_DATALIB call means that there are no more certificates. This is perfectly normal. So, if there are 5 certificates, each time there will be a data getnext call, which will get RC=0, until the last one, which gets the 8/8:44 (x'2C') because there are no more certificates.
