Dynamically extending the Jobtrac 161 database area while the database is open

Products

Issue/Introduction

    Jobtrac database area is approaching capacity and needs to be increased.  Is there a way to increase the 161 database area while database is open and without having to take Jobtrac down?

Environment

Jobtrac 11.0

Datacom/AD 15.1 15.0

Resolution

Datacom/AD r15.0 and later has a modified extend command that can be used within the MUF joblog to allocate additional space while the base is open.

The DYNAMIC_EXTEND can be issued either as a console command to the MUF or via DBUTLTY COMM statement.

Below is an  example of the command syntax  issued via DBUTLTY COMM statement :   

DYNAMIC_EXTEND 161,IXX,###,CYL 

 

Below is an example of console command to the MUF: 

/F mufstc,,DYNAMIC_EXTEND 161,IXX,50,CYL

 

This command will also work for Datacom/AD 14.0 when RO71530 has been applied.  This can be done during live Jobtrac access to the base. 

The on-demand DYNAMIC_EXTEND feature is discussed in   Datacom Core - 15.1 section in section entitled  DYNAMIC_EXTEND

For additional information please also  refer to the example shown in the following Datacom/AD article “How to extend a  Datacom area while the database is open” which shows an example for base 430, area IXX.  For Jobtrac  use DBID 161 to increase the space to the desired size.
