Question :

In the db2diag.log file – I’m getting the the error message

Vendor RC=0x00000019=25 -- see DB2 API Guide for meaning.

How can I troubleshoot the  SQLUV_IO_ERROR  25   IO error encountered  error message?

Answer:

Read the post Troubleshooting DB2 Return Codes, failed to archive log and SQLUV_INIT_FAILED   for DB2 return code interpretation

The definitions for all DB2 to Vendor API return codes are found under the instance home directory <sqllib>/include/ in the sqluvend.h header file.
The DB2 error code returns :
#define SQLUV_IO_ERROR         25  /* I/O error encountered */
The Vendor Code is returned using the return code 155
0155 T: DSM_RC_COMPRESS_GREW Compressed Data Grew
Explanation

 


The size of the file after compression is greater than the size of the file before compressed.


System action


Even though the size of the file increased, the file is compressed.

The error message  related to  TSM  trying to compress an object that has already been compressed.  Setting the local option file to  COMPRESSALWAYS  is YES overrides this error.
