After customizing Thread Terminator for Db2 for z/OS (PTT) the following message is seen:
TT005E: DSNALI module not available. Load from DB2 Loadlib failed.
The Db2 SDSNLOAD loadlib is not concatenated in the Xmanager STEPLIB.
Check the Xmanager started task and verify that the Db2 SDSNLOAD loadlib is concatenated in the STEPLIB:
//STEPLIB DD DISP=SHR,DSN=<hlq>.CDBALOAD
// DD DISP=SHR,DSN=<hlq>.SDSNLOAD
If the Db2 SDSNLOAD loadlib is not present in the STEPLIB add the library and recycle Xmanager.
