|
| The following error message is display when sending: :: '''Microsoft Access - System resource exceeded'''
| | This problem was fixed with [[CCMDB.accdb_Change_Log_2019#2019-12-07]]. |
| *Internally this is also noted in the dbengine object as error number 3035.
| |
| *The error occurs specifically when the send program runs [[Query send check centralized is owner]].
| |
|
| |
|
| == Interim work-around: Pagasa will send for a collector who gets this error ==
| | See page history for details, deleting from here so they don't pollute the searches. |
| *Nov 28.19- '''Sending only allowed between: 1430 to 1530 daily'''.
| |
| *'''NO SENDING or ADDING NEW DATA to your CCMDB records after 1530 daily''' ---until further notice.--[[User:TOstryzniuk|Trish Ostryzniuk]] 11:43, 2019 November 28 (CST)
| |
| **'''Collector''': must finish going through all data entry for that day that would benefit from Patient Copier since you will need to delete records as part of this
| |
| **'''Collector''' must run [[Pre-send Checker]] and correct all error ID'd before running [[News and backup]] '''each day'''.
| |
| *Try sending.
| |
| *If get this error message, stop trying to send
| |
| *'''Collector''' must coordinate with '''[[p:Pagasa Torres | Pagasa]]''' so that Pagasa can send your completed files. You must work very closely together on this so that no records are lost.
| |
| **'''Pagasa and Collector''': establish a phone call or email between the two of you
| |
| **'''Collector''': close out of Access and leave Access closed.
| |
| **'''Pagasa''': download the newest backup file.
| |
| **'''Pagasa''' will email the '''Data Collector''' to open their CCMDB and delete all the COMPLETED profiles.
| |
| **'''Collector''' '''must check email''' for notification from '''Pagasa''' that they can proceed in the follow order to:
| |
| ***(a) delete COMPLETED files
| |
| ***(b) do New and Backup and
| |
| ***(b) now be able to add any new data to their CCMDB
| |
| *'''Collector''': you must delete the completed files because otherwise it will be impossible otherwise to distinguish between the completes that Pagasa sent, and the completes she has not yet sent.
| |
| *'''Collector''': after you delete the completed files Pagasa sent, you must do one more News and Backup. This will help reduce the number of records being kept on laptop that no longer need to be there.

| == Observation - A new build of Windows10 was deployed at around the same time this became more common again ==
| |
| * In order to find out the running Windows 10 version do this:
| |
| ** Press the Windows key + R
| |
| ** Type winver
| |
| ** Press Enter
| |
| ** The result will be the About Windows window with information on the current running build. e.g: Version 1809 (OS Build 17763.720)

| |
| | |
| == Observation - Timing of this becoming a problem again ==
| |
| *Pagasa observed that this became a problem again around the same time we changed the schedule of [[PHI Loader.accdb]]. We discussed possible connections but could not think of anything causal. Just putting this down here in case someone else can think of the connection. Ttenbergen 15:34, 2019 September 12 (CDT)
| |
| ***Pagasa and Tina had a look at STB_MEDD (Debbie’s) data, and it possibly seems to be a matter of there really being too many records. MS Access is reaching its limit. For testing I tried to send with the first half of your patients and with the second half, and each works. Of course that is not a solution, but it confirms that the volume is the issue. In the long term we need to find an alternative to MS access, and to bring down the backlog, but that won’t be quick.
| |
| | |
| == Solution approach: Purging some old data from centralized ==
| |
| I made a copy and deleted records:
| |
| * all child records before 2015-01-01 (ie kept L_Log complete, but deleted corresponding records in L_TmpV2 etc). This shrunk centralized from 1GB to 618MB. However, it did '''not''' solve the problem.
| |
| * all records before 2019-01-01 (incl. Log purge)
| |
| ** this would create a problem because [[Query send check centralized is owner]] would no longer be able to conclusively check for records that already exist in the db, ie. someone accidentally uses Pat_ID 100 rather than 1000)
| |
| | |
| == Solution approach: Query size limiting ==
| |
| The error happens when trying to run [[Query send check centralized is owner]]. That query actually ties into the [[Centralized data.mdb]]'s L_Log. This makes for a very large record set, and have a max size of 1GB rather than the general Access limit of 2GB.
| |
| | |
| * 13:29, 2019 September 4 (CDT) - optimized the query further, seemed to eliminate error for now, but error has recurred since
| |
| | |
| == Solution approach: disconnecting wifi ==
| |
| Darryl from STB desktop had suggested that turning off wifi might fix this problem. Since they don't actually have wifi in their area this is easy to try. This worked during his tests, but they have had additional problems sending after that.
| |
| | |
| During additional tests at HSC Tina found out that sending is faster with wifi disabled, so she added some lines to the sending code that disconnect wifi at the start of sending.
| |
| | |
| == Solution approach: Maxlock setting ==
| |
| *https://access-programmers.co.uk/forums/showthread.php?t=285553 sugggests to apply the following
| |
| **DBEngine.Idle dbRefreshCache
| |
| **DbEngine.SetOption dbMaxLocksPerFile, 1000000

| Tried, doesn't solve the problem

| ==Status==
| |
| As of 09:48, 2019 September 4 (CDT) this is still a problem, and recently more of a problem.
| |
| | |
| Next things I will try:
| |
| * try to send from local to local - the query works fine when I run it while connected to a local version of CFE
| |
| * updating ccmdb.mdb to .accdb; if that is the solution we will also need to update many scripts and VBS/VBA programs.

| ** Big queries?
| |
| *** Had heard about update queries in general being more likely to cause this error; ours isn't an update on. It is large-ish, but as small as it can be. When the query runs successfully it finishes in ~5 seconds, so I kind of doubt the size is the issue.

| ** Windows 10?
| |
| == Steps Sending Locally ==
| |
| ** Open ccmdb.data.mdb
| |
| ** Go do Database Tools
| |
| ** Visual basic
| |
| ** Click Global -You will see txt message
| |
| *** ‘ Public Const Centralized_data_accdb = Outpath & "Centralized_data.accdb" –become green once you add apostrophe (')
| |
| *** Public Const Centralized_data_accdb = "C:\Centralized_CCMDB\" & "Centralized_data.accdb"
| |
| ** Then save
| |
| == Sending ==
| |
| | |
| ** Before you send make sure you have the newest version of ccmdb.data.mdb and you are in Pull of CFE
| |
| ** Copy the latest backup you want to send
| |
| ** Click Send
