Error description
When you do either a CEMT INQUIRE CONNECTION or an INQ UOWLINK you get an abend AEXZ. This is occuring because there are no more RMTK tokens for the link browses. You will see RMLN START_LINK_BROWSE return with a browse token of x'00000000'. This is then followed by the GET_NEXT_LINK with RESPONSE(EXCEPTION) REASON(INVALID_BROWSE). RMLK class anchor + 470 = 000000FF. Which is the number of blocks allocated for the RMLK browse token set. 'FF' does not allow for any more to be allocated.

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: INQUIRE CONNECTION and INQUIRE UOWLINK * * may abend AEXZ. * **************************************************************** * RECOMMENDATION: * **************************************************************** In the reported problem, a task issued an INQUIRE CONNECTION command. This caused DFHEIUOW to attempt to scan for UOW Recovery Manager Link Objects. To do this, DFHEIUOW required a UOW_BROWSE_TOKEN but was unable to obtain one because they had all 'leaked' from the system. As a consequence, the task abended AEXZ. . The uow_browse_tokens had 'leaked' due to prior INQUIREs not performing an DFHRMLNM END_LINK_BROWSE call which would have freed the tokens for subsequent reuse. The same problem could occur with INQUIRE UOWLINK BROWSE. . Keywords: abendAEXZ
Problem conclusion
DFHEIUOW has been amended by the addition of a DFHRMLNM END_LINK_BROWSE call which will free the browse token.
