Part II, Using the Reporting Services Trace Log File – Dean Kalanquin's Reporting Services Blog. Hey There – About a year ago I posted thisblog about troubleshooting subscriptions. Since then I’ve received quite a few questions and come across more subscription problems in our production Reporting Services server that identified a few gaps in my previous posting, so I thought I would elaborate more on the subject here. To recap a few key points from before: When you create a subscription several things are added to the RS server: - A row is placed in the Subscriptions table. I often find my investigation of these problems go well beyond my “this can usually be tested by running the report manually” recommendation, so I’ll attempt to give this area better justice here by sharing some of my experience with the trace log file. The Trace Log: More Than You Ever Needed or Wanted to Know About Your RS Server. The trace log file is created in a folder under your SQL Server installation path.
In my machine this happens to be: C: \Program Files\Microsoft SQL Server\MSRS1. Previous versions of SQL Server will be named differently, but your’s should be in a similar location. A quick search of the SQL Server books online will give you some configuration options that allow you to control how big the files get, how long they are kept, and the type of information and activities that are logged to the file and so on. For a detault RS installation, these files will be limited to a max size of 3. The file will also be closed and recreated each time the RS server is recycled, which by default will happen every day at midnight.
The name of the trace log file will be similar to . If you happen to be researching a problem that just ocurred, you can just view the newest file, otherwise you will have to find the file that contains the range of information including the entries you are looking for, based on the timestamps in the file names and the entries in the file. A common response when people ask for help with a report problem is, “What did you see in the trace log file?”.
However, it can be a bit daunting the first time you open the file, and it can take some practice to get good at reading it effectively. The first problem is the sheer bulk of content that is logged in the multi- mb file, and the next problem is the cryptic nature of the multi- mb content. I’d like to help you make sense of this information to diagnose and fix subscription and other Reporting Services problems. This file contains a multitude of information about practically every action, operation, process etc that occurs in the RS server. Some of them are for internal processing, and some are related to the processing of reports, subscriptions or other user initiated or defined operations.
For example: library! Windows. Service. W G A V Crack Iit on this page.
Ensure the user name and password are correct. First of all, each . The remaining parts of the entry line describe what occurred in the server. And finally, as you will see below, there is sometimes a set of callstack frames following (what I call) the regular entry lines, and they typically have the form: at System. Data. Sql. Client.
Sql. Connection. On. Error(Sql. Exception exception, Boolean break. Connection) at System. Data. Sql. Client. Tds. Parser. Throw.
Exception. And. Warning(Tds. Parser. State. Object state. Obj)These entries refer to the code inside the Reporting Services server and its referenced libraries. They will not typically be of much value to you in researching report or subscription errors, but if you do happen to experience other types of RS server problems (or yes, even server bugs we may have unfortunately missed in testing), including the callstack with an explanation of the problem will be very helpful for us or CSS to understand more about the problem. Locating Subscription Entries in the Trace Log File.
Step 1: Get the Schedule Id. A good general approach to researching problems in the trace log file is to determine when a problem occurred, find the entries in the log file around that time, and just start poking around.
This can be enough if you have a quiet RS server with very little activity, but an active server can have hundreds of entries within a few minutes, so “poking around” may not be too successful. The next step would be to get a more precise date/time value for when a problem occurred, this can be obtained from the Time.
Start or Time. End fields in the Execution. Log table, or the Last. Run. Time field of the Subscription table in the catalog database. But again, even with this information, there may still be hundreds of entries in the trace log file at key times (say, 8am) when there is a lot of other successful and unsuccessful subscription or report activity in the server at the same time as the failed subscription. Adobe Professional 8 Serial Number.
The key point in isolating subscriptions further goes back to what happens “When a subscription runs”. As I said before, when a subscription runs, the status in the subscription table is updated, but I should have added “andentries are placed in the trace log file with the schedule id.” In other words, the key link between a subscription execution and the entries in the trace log file is the schedule id for the subscription.
The schedule id must be obtained from the Subscription table, it is not visible via the UI tools, and the query below can help, assuming you understand the legal stuff: Disclaimer: we do not officially support querying all of the Reporting Services tables mentioned below, the columns and information in them may change in the future. Subn. Desc'= s. Description,'Subn. Owner'= us. User. Name,'Last. Status'= s. Last. Status,'Last.
Run'= s. Last. Run. Time,'Report. Path'= c. Path,'Report. Modified. By'= uc. User. Name,'Schedule. Id'= rs. Schedule.
Id, - - This is what you need'Subscription. Id'= s. Subscription.
IDfrom Report. Server. Subscriptions sjoin Report. Server. dbo. Catalog c on c. Item. ID = s. Report. The good news is that the schedule id is a guid; the only entries you find in the file with that string will be the entries for this subscription. I only use custom schedules, and the examples here assume a custom schedule. The not- so good news is that if the subscription fired several times within the timeframe of the contents in the trace log file, you will have to find the entry nearest to the one that failed based on the timestamp of the entry.
In my local server, I created a subscription and waited for it to fire. The rows in the Subscription table using the query above told me that my schedule id was “4. Windows. Service. Your log file content may be somewhat different, but the approach is the same. Step 3: Look at the other entries with the same thread in the same time proximity.
Based on the entry above with the schedule id, you can see that the thread is “1. Windows. Service. I also used a quiet local report server, so all my entries were literally next to each other in the file making them easy to identify. But again, in our production server, there are a lot of subscriptions firing at common times, so their entries may be spread more broadly throughout the file. Also, be careful to watch the timestamps of the entries for each thread, if the same thread happened to process another subscription later, you need to make sure you don’t associate your current subscription with the entries for the next.
Common Types of Subscription Failures. Now, lets have more fun and look at a couple common types of subscription errors and their trace log file entries. Invalid logins. In today’s world of defense against hackers (those guys really take the fun out of developing software. L) the sorry truth is that SQL passwords have to expire.
This is the most common cause of recurring problems I see, and they often happen when people forget to update their passwords in all the necessary data sources. In my example here, I changed the password for the data source of the report used by my subscription to be invalid.
