As of version 10.5.1, you can configure IMS netport jobs and PowerCenter Db2 Loader connections with a user ID and a long passphrase. Before this enhancement, PowerExchange restricted the password to eight bytes or less.
You must modify the JCL templates to adhere to the following rule:
The PASSWORD=%PWD specification must start at column 4 and it must be on a JCL line by itself within the JOB statement at the beginning of the template JCL.
This rule applies to the JCL templates in the RUNLIB data set including DB2LDJCL, DB2LDJCP, IDMSMJCL, and IDMSMJCX.
