A customer has recently upgraded to a z13 processor. As part of the migration process, the LPAR image profiles ware copied form the old processor to the z13.
After the upgrade, transactions on the production z/OS environment continue to run well; however, in the development z/OS environment, transactions are now timing out.
What tool should the technical specialist use to help the customer resolve this problem?
IBM's Processor Capacity Reference (zPCR) is a PC-based productivity tool under Windows. It is designed to provide capacity planning insight for IBM System z processors running LPAR configurations with various workload environments under z/OS, z/VM, and Linux. Capacity results are based on IBM's LSPR data supporting all IBM System z processors.
Which type of coupling link allows two z13 machines to connect at the maximum distance apart?
The HCA-O LR fanout supports InfiniBand 1x optical links that offer long-distance coupling links. With direct connection, the supported unrepeated distance3 is up to 10 km (6.2 miles), and up to 100 km (62 miles) with z Systems qualified DWDM.
A customer has just installed a new z13s. They need to obtain the required configuration file for channel-path identifier (CHPID) mapping to the new system.
Where can a customer access this information directly?
The eConfig tool is available from an IBM representative. Use it to build new configurations or upgrades of existing configurations and to maintain installed features. eConfig also produces a PCHID report.

A customer has decided to move all of their Linux workloads from their current x86 platforms to a recently purchased IBM LinuxONE Rockhopper. To simplify the migration process, the customer will continue using KVM as the hypervisor. The x86 administrator has no experience with the LinuxONE Rockhopper, but is expected to create and provision new LPARs to support the migrating Linux workload.
What tool could the x86 administrator use to simplify the creation of new partitions and the configuration of I/O adapters?
A new administrative mode, IBM Dynamic Partition Manager (DPM), is introduced for Linux only systems for IBM z13, IBM z13sTM, IBM LinuxONE Emperor (Emperor), and IBM LinuxONE Rockhopper (Rockhopper).
A customer is upgrading a zEC12 to a z13 and has FICON Express8 channels installed to support their 2Gb I/O devices, which must also be connected to the z13. They are migrating to the z13 to take advantage of larger memory configurations supported on the z13 for DB2.
In order to take advantage of LPARs which can support memory sizes greater than 2TB, what must be configured on this upgrade?
The FICON Express8S feature is exclusively in the PCIe I/O drawer. Each of the two independent ports is capable of 2 Gbps, 4 Gbps, or 8 Gbps. The link speed depends on the capability of the attached switch or device. The link speed is auto-negotiated, point-to-point, and is transparent to users and applications.
