Support - Maintenance:

The following are z/XDC maintenance files available for download. For more information about these files, including their maintenance levels and dates, select the appropriate "Text" button ( or ) under "Contents and Dates".

Please note, when downloading the "Maintenance (.ebc)" files:

• Mozilla Firefox Users: Right-click on the "Binary" button, then click on "Save Link As ...".
• Internet Explorer Users: Right-click on the "Binary" button, then click on "Save Target As ...".

General Instructions:

• Click on the above links to download the desired files to your PC.
• 1st Sanity Check: Check the EXACT byte length of the maintenance (.ebc) file. (One way to do this is with DOS's DIR command. Another is with the ZTREE program.) The length of maitenance file should be an exact multiple of 80. If this is not the case, then something is wrong. You may have to contact us for assistance.
• Upload the maitenance file to your mainframe as a binary file, i.e. with ASCII-to-EBCDIC translation turned OFF. Use IND$FILE, FTP, your workstation program's File Transfer Facility, or whatever program you have available to perform the upload.


The DCB attributes for the uploaded file must be RECFM=FB, LRECL=80, BLKSIZE=n*80.
• 2nd Sanity Check: Use ISPF View or Browse (or a similar program) to look at the contents of the uploaded file. Check the number of records that it contains. That number, times 80, should exactly match the maintenance file's size. If this is not the case, then the process that you used to upload maintenance from your PC to the mainframe has corrupted the file. (This is a problem that actually occurs more frequently than you would expect!)


Retry the upload, using a different method if you have one available. If you are still having problems, then contact us for assistance.
• To APPLY the maintenance, run the SMPMAINT job located in the DBCOLE.XDCZ18.INSTALL.JCLLIB library. For detailed instructions, please refer to the section of the "z/XDC Installation Guide" titled "Step 2: Run the SMPMAINT Job". You can download the Installation Guide from our Documentation page.
