With DBCTL, you must issue DBRC commands via DBCTL console commands (/RMxxxxxx) because DBRC runs outside the CICS® address space. You can issue the /RMxxxxxx commands via the CICS-supplied transaction CDBM.
You can use the following /RMxxxxxx commands online:
For example:
/RMINIT DBRC='DB DBD(IVPDB2) SHARELVL(3)'.
See the IMS™ Operator’s Reference manual for further guidance on the syntax of these commands.
You can also enter DBRC commands in batch, but the syntax is slightly different, as shown in Figure 22.
