Run an magento function cron at every hour

cron, magento, magento-1.7

Solution

Use this cron expression for each hour:

<cron_expr>0 * * * *</cron_expr>

This will make it run at `12.00`, `1.00` and so on. If you want to make it run at `12.30`, `1.30` and so on replace `0` with `30`

Problem

I want to run an magento function that would run at every hour , i am written code in config.xml but i did not working.here the code is ``` <crontab> <jobs> <stockalert_autosend> <schedule><cron_expr>**/1 * * *</cron_expr></schedule> <run><model>stockalert/observer::backinstock</model></run> </stockalert_autosend> </jobs> </crontab> ``` Please help me
