Question about SQL 2000 TLOG replication

Hi to all,
i have 2 questions about SQL replication :
1- If i configure a trasaction replication between 2 SQL server 2000 (online
and subscriber) and after i schedule the distributor agent for start onlyone
to week
this maybe generated a problem as more incresase of code and so slowing sql
or other proiblem ?
2- Exists any to the tail for replication ?
3- if i manually insert a data only on subscriber database can i generte any
replication problems ?!'! Problems as stop of replica or other problem ?!!?
4- What happened if i do a bckup log with truncate only for online databse
or distributor ?
Thanks in advance.I count 4 questions not 2, but whose counting?
1) This won't work unless you set the history retention to 14 days or so.
Once you do this you will find performance degrades after several days
depending on your load. Ideally you would run the agents continually.
2) What do you mean by the tail of replication?
3) if the data you enter on the subscriber conflicts with the data entered
on the publisher it will cause a problem. Use the continue on data
consistency error profiler to skip this.
4) This should work ok. Replication will work fine after a truncate.

No i would schedule the agent for example every week at 02:00

> 2) What do you mean by the tail of replication?
Sorry i would tell : Exists any problem if i schedule the agent for
distribution only every 2 week and the distribution database and the data to
replicate are more grows ?

Ideally you would replicate as frequently as possible, having the agent run
once or twice a week will not offer good performance if there is significant
load.
