If CA Vtape was installed with Dynamic Cache Management, the CA Vtape LDS allocations requested by the SVTS and SVTSAS started tasks should be exempted from third party DASD allocation control products. Products which intercept space abends or adjust allocation amounts based on DASD pool conditions are not needed since Space Constraint Relief is coded in the SMS data class defined for CA Vtape use. Also, CA Vtape requests specific primary and secondary space values based on the CachePrimary and CacheSecondary attributes coded in its parmlib and takes appropriate actions when these amounts cannot be honored. Adjusting these values with a third party product could result in CA Vtape taking inappropriate actions or an ABEND.
