https://www14.software.ibm.com/webapp/set2/sas/f/redAlerts/home.html
DESCRIPTION:
After the installation of the PTF(s) for APAR OA18860, a sysplex-wide hang can occur waiting for CATALOG resource SYSIGGV2 which requires an IPL of the system holding the resource in order to to recover. The PTFs in error
include: UA30834, UA30835, UA30836, UA30837 UA30838 for z/OS 1.4 through
1.8 respectively. A restart of Catalog is not sufficient to clear the condition. Please see APAR OA19429 for more information.
RECOMMENDED ACTIONS:
Issuing the following command on each system will show if the error PTFs are installed: F CATALOG,ENTRY(IGG0CLEG)
Schedule an IPL (with CLPA) to correct the problem on each system that contains the error PTFs by:
1) Applying the PTFs for OA19429 when available, or
2) Applying the ++APARs which are available from the Support Center, or
3) Restoring the error PTFs UA30834, UA30835, UA30836, UA30837, UA30838.
