zero byte extracting in PI

[Former Member]

Hi Experts,

i have weird situation here. We have a scenario where we are using file receiver adapter on the receiver side. We are placing the files in PI folder and MQ is picking up the files from this folder. We are using dynamic configuration for the file name for this interface. What happens is sometimes MQ is picking up zero size files even though PI is sending data in the message. File adapter is creating the file name from dynamic configuration but unable to write the data in the file even though the message is having the data and we are unable to reproduce this scenario again. This happens only for few messages.

Can you please help me on how to solve this issue.

Thanks,

Srinivas.

Hi Srinivas

If the problem is with message data , I mean if some times PI receive empty data, then you can choose the option 'ignore empty message'  option in the file receiver adapter.

are you creating the file directly or using temparory file name scheme?

Hi Hareesh,

Direct File name.

[former_member184720]

If your MQ is identifying the files based on the name, then you can use the temp file name scheme so that MQ won't be able to find the files.

PI will rename it to the actual file name only after writing the entire message content.

Hi Srinivas,

If XI put empty file in the directory then you can select ignore empty message option. But you confirmed XI put the file in the directory with the full data. hence issue is at the MQ end. When XI is trying to write the file in the directory, before the file completion MQ is picking the message. pls check with MQ team how they confirmed the MQ channel. is there any specific reason of using file adapter? you can use JMS adapter to send the message to MQ,

Cheers
