What problem are you trying to solve? Creating an alt master cat and importing it to a new system may only fix some of your issues.
Consider the master catalog like the ROOT in Unix. It controls where things can be found in z/OS. It is the key to the IPL Process. If anything is not correct in the MCAT then an IPL may not work. There is a manual on working with catalogs. And if this is not a sandbox - that is - if this system cannot take outages if there are issues you should take care there could be challenges by doing this. It helps if you have a system programmer sandbox when working with catalogs. This is an environment where if things get broken, there is not impact to other work going on in the shop. If there are issues with your catalog, you may need to IPL or other activities to fix it. For example - catalog recovery processes If you are not the system programmer, you should contact the one at your shop. They can help you with your activities and reduce potential problems. This list does not know your shop or your configuration. It can only provide guidance based on information provided. You system programmer can be better at helping you with these types of questions. When you import the master cat from another system, you cannot not see all of the datasets. Anything currently cataloged on the new system in the MasterCat may not be seen. If you want datasets that are in the MCAT on SYSA on SYSB and you want are SYS1.** datasets, then you may not see them on SYSB. A catalog is a tree structure. MCAT entries over ride UCAT (user catalog) entries. IMPORT CONNECT does - https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.idai200/toc.htm The IMPORT command moves or restores a cluster or alternate index, or restores a catalog. Import a Catalog: Example 2 https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.idai200/imicf.htm In this example, a catalog, USERCAT4, that was previously exported, is imported. (See the EXPORT example, Export a Catalog: Example 1.) The original copy of USERCAT4 is replaced with the imported copy, from the portable file copy in CATBACK. Access method services finds and deletes the duplicate name, USERCAT4. Any aliases in the master catalog for USERCAT4 are preserved. (A duplicate name exists because the catalog was exported with the TEMPORARY attribute.) Access method services then redefines USERCAT4, using the catalog information from the portable file, CATBACK. USERCAT4 is locked to prevent access to anyone except authorized recovery personnel. Another search for CONNECT MASTER CATALOG in www.ibm.com produces many hits https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.e0zb100/migrtas.htm Migrating to another system section in z/OS Planning manual. This section only lists actions you need to take to move a copy of software from one system to another. It does not list the actions needed to install and migrate new levels of software. For that information, see other documentation such as z/OS Migration. I went to www.ibm.com and searched on CATALOG MASTERCAT http://www-01.ibm.com/support/docview.wss?crawler=1&uid=isg3T1019473 http://www-01.ibm.com/support/docview.wss?uid=isg1II13354 And many other hits. I went to http://www.redbooks.ibm.com/redbooks.nsf/searchsite?SearchView And searched on CATALOG in the REDBOOK site on IBM. Many hits that will be helpful http://www.redbooks.ibm.com/abstracts/sg248262.html?Open http://www.redbooks.ibm.com/abstracts/redp4212.html?Open http://www.redbooks.ibm.com/abstracts/sg246983.html?Open ** There are a series of Redbooks called ABC and ABCs and they explain a lot of the functions in z/OS and how to work with them http://www.redbooks.ibm.com/abstracts/sg246105.html?Open There are many more.
