I have a VSAM DB where its reaching 3.7 GB regularly.Hence we want to change it to OSAM so that 8 GB of space is available and prevent DB crash. We are using IMS batch &online programs to access the DB.
I would like to know
1)how complex is the process of converting VSAM to OSAM DB
2)does the existing programs needs to be changed so that they are compatible to OSAM
3)does the existing jcl's needs to be changed so that they are compatible to OSAM
I am reading about OSAM for 1st time and any information would be greatly helpful.
