hi this is madhu.
main differences b/w datastage 7..52 to 8.0.1
1. in ds 7.5.2 we have manager as client. in 8.0.1 we dont
have any manager client. the manager client is embeded in
designer client.
2.in 7.5.2 quality stage has seperate designer .in 8.0.1
quality stage is integrated in designer.
3.in 7.5.2 code and metadata is stored in file based
system.in 8.0.1 code is a file based system where as
metadata is stored in database.
4.in 7.5.2 we required operating system authentications. in
8.0.1 we requiree operating system authentications and
datastage authentications.
5.in 7.5.2 we dont have range lookup. in8.0.1 we have
range lookup.
6. in 7..5.2 a single join stage can't support multiple
references. in 8.0.1 a single join stage can support
multiple references.
7.in 7.5.2 , when a developer opens a particular job, and
another developer wants to open the same job , that job
can't be opend. in 8.0. it can be possible when a developer
opens a particular job and another cdeveloper wants to open
the same job then it can be opend as read only job.
8. in 8.0.1 a compare utility is avilable to compare 2
jobs , one in development another is in production. in
7.5.2 it is not possible
9. in 8.0.1 quick find and advance find features are
avilable , in 7.5.2 not avilable
10.in 7.5.2 first time one job is run and surogate key s
generated from initial to n value. next time the same job
is compile and run again surrogate key is generated from
initial to n. automatic increment of surrogate key is not
in 7.5.2. but in 8.0.1 surrogate key is incremented
automatically.a state file is used to store the maximum
value of surrogate key.
